Description
The present invention relates to a kind of be used to clean IC engine lubricating oil freely spray sedimentator, it has a shell by a removable sealing cover sealing, has a rotor that can be rotatably set in the shell, and have and be used to import and be cleaned, be in the passage and the passage that is used to discharge the stress-free lubricating oil that has cleaned of the lubricating oil under the pressure, wherein said rotor double-body bike ground constitutes, promptly, comprise that one has the driver part of at least one recoil nozzle and dirt that one has a dirt collecting region captures parts, wherein driver part can divide circulation stream by one first lubricating oil, and dirt captures parts can divide circulation stream by one second lubricating oil, wherein driver part and dirt capture parts be configured with form fit is connected mutual coefficient torque-transmitting mechanisms, they are received on the driver part and mesh by dirt being captured the component axial cover, and from driver part, axially extract the disengaging engagement by dirt being captured parts, wherein dirt capture parts are separated with driver part in order to remove or to clean, and wherein in sedimentator, be provided with or Placement Cell, they are used to prevent or limit dirt capture the axially-movable of parts with respect to driver part in that sedimentator is in service, and they lost efficacy when taking off sealing cover and maybe can unclamp.
Disclose first kind by DE 200 10 612 U1 and freely sprayed sedimentator.In this sedimentator, rotor case is made up of two parts, and they releasably interconnect, and wherein driver part has first bindiny mechanism, and dirt capture parts have corresponding second bindiny mechanism.These bindiny mechanisms are made of fast kayser in concrete embodiment, and the limited rotation of two parts that it can be by rotor is meshing with each other or breaks away from engagement.
For this known sedimentator alleged occurrence defective of freely spraying, for capturing parts, separates the dirt that makes rotor with the driver part of rotor, must at first whole rotor be taken out from the shell that freely sprays sedimentator, must rotate relatively at two parts that apply under the condition of certain torque rotor then, this need be used to unclamp fast kayser.Because the rotor that should freely spray sedimentator is in service also lubricated by fuel injector on its outer surface at it, often is difficult to manually apply and is used to remove and set up the required torque of connection between two rotor parts.This just needs especially to be used to unclamp the required torque of fast kayser at the oil that two rotor parts are adhered at first must the rotor for cleaning outer surface before being separated from each other so that can apply.Scheme also it is contemplated that tool using as an alternative, but must make two rotor parts be furnished with the placement surface that is suitable for each instrument on the one hand for this reason, and must prepare suitable specific purpose tool on the other hand, they can be chimeric with each parts in two rotor parts.In all cases, if make rotor be divided into two parts, this is necessary when freely spraying sedimentator and maintain at every turn, all causes a time-consuming and loaded down with trivial details rotor operation.What be regarded as defective in addition is, need a firm and measuring body rotor here, because have whole hydraulic pressures of the lubricating oil that will be cleaned at internal rotor, because all are input to the recoil nozzle in the driver part then by the at first through-flow internal rotor of oil stream that sedimentator imports.
Disclose a kind of device that is used to make the crank case of internal combustion engine exhaust by DE 43 11 906 A1, wherein this device comprises a separating mechanism that is used for making the oil particles that imports to crank case gases together, and it is connected with a blast pipe that directs into gas handling system.Use an oily sedimentator that is used to clean IC engine lubricating oil at this as separating mechanism.The rotor of this oil sedimentator is made up of two parts, and they interconnect hermetically in that sedimentator is in service.Do not have to describe in above-mentioned document about two mutual separabilities of rotor part, therefore infer thus, described rotor part is although made still subsequent connection for good and all by single parts.And in this document also openly dirt capture parts and the independent erasability that is deposited in dirt wherein.For this sedimentator, rotor also is under the hydraulic pressure of the lubricating oil that will be cleaned, wherein this hydraulic pressure is used for making rotor to be in operation lifting from its lower bearing targetedly, and with respect to a cod roof pressure that is arranged on rotor end face and the sedimentator casing cover bottom surface.This rotor must firm and resistance to compression ground formation thus.
Disclose the another kind of sedimentator that freely sprays by DE 1 012 776 B, wherein this rotor double-body bike ground constitutes.Two parts of this known embodiment rotor radially below and the outside have an overlapping part, this overlapping part they by a plurality of screw elements sealings and releasably interconnect.Can realize a removing that separates or cleaning although have only the dirt of rotor to capture parts thus, but rotor is splitted into dirt capture parts and driver part owing to must unclamp connecting thread spare one by one, thereby be loaded down with trivial details and time-consuming, subsequent is loaded down with trivial details and time-consuming with their assemblings equally.Also need a firm and measuring body rotor in addition here, because have whole hydraulic pressures of the lubricating oil that will be cleaned, because the also at first through-flow internal rotor of lubricating oil here just is input to the recoil nozzle in the driver part then at internal rotor.
Disclose a kind of rotor that is used for freely spraying sedimentator by WO 98,/46 361 A1, it has at least one guiding parts, and this guiding parts extends to outer wall from an inwall in internal rotor space.By this guiding parts or a plurality of such guiding parts rotor is strengthened like this, make to have such possibility, make it make by a kind of plastics.Here made by two parts according to a kind of this rotor of described embodiment, they are interconnected to, tighten into complete rotor here.Constitute this chucking bindiny mechanism like this at this, make and after connecting first, no longer can without damage separate these two rotor parts, because whole rotor makes it not have cost defective ground can be entirely processed after it uses to fall because it is made of plastics and becomes cheap in this wise.For this known rotor within it portion be in operation and also have whole hydrodynamic lubrication oil pressures because the at first through-flow internal rotor of lubricating oil space then is input to the recoil nozzle that is used to drive rotor.Here rotor also needs a kind of firm structure thus, is used to realize required crushing resistance.
Disclose a kind of sedimentator that freely sprays in DE 1 105 351 B, it is different with common device to have particularity, and the driver part that promptly has the recoil nozzle constitutes a upper member of rotor, and the dirt of rotor captures parts and constitutes its underpart parts.Two rotor parts interconnect hermetically and releasably by a plurality of connecting thread spares.Also there is defective here, must at first this rotor be intactly split out to come from shell, can must unscrew a plurality of screw elements with before driver part separates making dirt capture parts then in order to take rotor apart.This assembling needs higher relatively cost, can not realize that thus this sedimentator simply and rapidly safeguards.Firm and the resistance to compression of rotor ground is constituted, because rotor is under the full lubricating oil pressure, because through-flow recoil nozzle is followed in the also at first through-flow internal rotor of lubricating oil space here.
WO 00,/23 194 A1 illustrates a kind of sedimentator, and it has the rotor of a double-body bike.Two parts of this rotor or can be threaded mutually can keep a kind of later separation thus, perhaps make their for good and all bonding mutually or welding.At the separation of separable embodiment rotor be used to pack into rotor insert and after certain running time, be used for necessary maintenance afterwards and change this rotor insert.In this known sedimentator, drive unit spatially is provided with the rotor compartment of terrain and or forms by a turbine or by a motor.Two kinds of drive units are compared with epitrochanterian recoil nozzle all to be very bothersome and not only to have higher manufacturing cost but also cause a bigger installing space for sedimentator.This point contradicts with the manufacturability of a common compact structure of pursuing and cost economy.
By provide a kind of rotor structure assembly that is used as the parts of sedimentator than not pre-disclosed DE 10 2,004 005 920 A1 early, be used for from a kind of material of liquid separating particles form.Described rotor structure assembly comprises a collecting chamber, and it holds a particle sorting apparatus, and the drive chamber with main turbine (Hero-Turbine).This drive chamber can be assembled into and can separate with it with collecting chamber.Cooperating between drive chamber and the collecting chamber is directly delivered to the collecting chamber that is used for particle separation with each by the rotatablely moving of drive chamber that main turbine causes.By drive chamber can be separated with collecting chamber, can handle collecting chamber and the sediment that is accumulated in wherein.
Be that described drive chamber is positioned at the outside of collecting chamber fully, here for the bottom for what this known rotor structure assembly was regarded as defective.This make except two be arranged in the drive chamber zone bearing with external away from drive chamber, here be always to need one the 3rd bearing on the upper end of collecting chamber, be used for guaranteeing enough well to support pivotally collecting chamber.This 3rd bearing causes making and assembly fee increases, and causes an additional weight.Be regarded as in addition disadvantageously, when each taking-up and installation collecting chamber, the 3rd bearing on top bears mechanical stress, and this is disadvantageous for its service life.Exist the 3rd bearing thus along with the time has the danger of the attrition value of an increase, this will make otherwise the rotor speed that can realize reduces.What also be regarded as defective at last is, can not guarantee when taking out collecting chamber from the sedimentator shell, makes drive chamber be retained in sedimentator inside reliably.But may by mistake make and when taking out collecting chamber, also carry drive chamber, make the mode machinery carrying of two bearings not expect of drive chamber thus.Each damage of bearing here also causes increasing bearing wear and causes rotor can realize the reduction of rotating speed under given driving power.
Summary of the invention
Therefore the objective of the invention is, what a kind of above-mentioned form was provided freely sprays sedimentator, it avoids above-mentioned defective, and especially realize a kind of light and compact structure form, assurance is with the easily revolution enduringly of high rotating speed, and the dirt that can take out and handle rotor easily respectively captures parts and can be rapidly and carry out required maintenance work easily.To realize a kind of high efficiency, a kind of high operational reliability and a kind of processing economically at this.
Be achieved according to the sedimentator that freely sprays of this purpose of the present invention, it is characterized in that by a kind of above-mentioned form
-described driver part extends in the dirt capture parts from bottom to top or wears this dirt thoroughly and captures parts extension,
-described driver part comprises the parts of the rotatable supporting rotor that is useful on, and
-described driver part prevents axially supporting when opening sealing cover with drawing.
The invention provides a kind of sedimentator that freely sprays, it has a kind of simple and therefore economic structure with a kind of compactness and relative lighter version on the one hand, and it is reliable being in operation on the other hand, and can be rapidly and maintenance easily, wherein can only from shell, take out dirt and capture parts and be deposited in wherein dirt.Because will carry out a kind of regular maintenance for internal combustion engine, normally change oil and change oil strainer, therefore suit to design sedimentator like this, make the dirt capture parts of its rotor have a dirt saturation, it is designed to be enough to satisfy the maintenance time interval of a regulation.According to a major advantage of freely spraying sedimentator of the present invention be, described driver part as service life structure member in its whole service time, can be retained in sedimentator the inside.When safeguarding sedimentator, avoid unnecessarily changing driver part thus, save cost thus.Because described driver part comprises the required parts of swivel bearing rotor that are useful on, promptly especially to its required bearing, need not separate when dirt captures parts and assemble bearing again changing, this helps the quality and the service life of bearing, and guarantees a high rotor speed enduringly.Capture in the parts, extend to promptly that it is inner or pass dirt and capture parts and extend by making driver part extend to dirt from bottom to top, can make bearing rotor axially on advantageously mutually remotely at interval.Thus in the outside of driver part, for example capture at dirt that the swivel bearing for rotor does not need the 3rd an additional bearing on the upper end of parts, but guarantee that also rotor well turns round.The bearing that prevents the driver part of axially drawing when opening sealing cover is avoided capturing parts with dirt undesirably reliably and is drawn driver part, and is responsible for making driver part always to be retained in the sedimentator the inside thus reliably, and makes bearing injury-free.
Have such characteristic according to the sedimentator that freely sprays of the present invention in addition, described driver part and dirt capture parts and divide circulation stream by self a lubricating oil respectively.Thus can in service need of sedimentator make driver part be in whole, clean under the hydraulic pressure of lubricating oil by the pump of carrying lubricating oil being used to of producing, and the hydraulic pressure of the lubricating oil that will be cleaned is no longer carried in the internal rotor space.This point for example can realize thus simply, the oily passage that makes the lubricating oil that will be cleaned be transported to internal rotor has a cross section and dwindles part, and the hydraulic pressure of the lubricating oil of being carried thereon that will be cleaned is throttling downwards before entering internal rotor.Rotor only need be born since its rotation produce, by the power that centrifugal force causes, obviously alleviate the load of rotor thus.This point allow to use simpler and/or still less seal and more low intensive material or reduce the wall thickness of rotor.
In order to make two rotor parts be separated from each other as far as possible simply and interconnect on the one hand, simultaneously in order to guarantee that making dirt capture parts does not have slippage ground and the synchronous also regulation of rotating of driver element, described driver part and dirt capture parts and are configured with mutual form fit and are connected coefficient torque-transmitting mechanisms, and they are by simple axially socket and axially draw away engagement and break away from and mesh.Thus for make dirt capture parts be connected with driver part or make these parts be separated from each other need only in a direction, be that axial simple motion is just enough.Here need not apply rotatablely moving under the torque condition, as for example for a fast kayser required, perhaps need not to unclamp and be provided with a plurality of single screw elements.
In order to guarantee that described dirt captures parts and axially keeping its position with respect to driver part after the socket, be provided with in sedimentator or Placement Cell, they are used to prevent or limit dirt capture the axially-movable of parts with respect to driver part in that sedimentator is in service.These mechanisms are constituted like this, make them invalid or unclamp when taking off sealing cover.Guarantee in this way to capture parts and keep its assigned position freely spraying sedimentator described dirt in service, guarantee sealing required between two parts of rotor thus and required driving torque is delivered to dirt capture parts from driver part with respect to driver part.
In according to another organization plan that freely sprays sedimentator of the present invention, described driver part comprise a center, the body that constitutes a grease channel and the nozzle supporting mass that at least one extends radially outwardly from body, it has at least one oil content subchannel that directs into the recoil nozzle.Realize a kind of favourable organization plan of driver part in this way, wherein said body is used for supporting rotor aptly and is used to make oil to direct into the internal rotor space, and makes the nozzle supporting mass be used for fixing nozzle and the oil that is used for being under the pressure is transported to nozzle.The nozzle supporting mass is positioned at below the body; Scheme also can be arranged on the nozzle supporting mass on the body in the above as an alternative.
In another improvement project of the described said structure that freely sprays sedimentator, described nozzle supporting mass has the shape of double bottom, constitutes the oil content subchannel therebetween in the space.In this structure, the oil that the intermediate space between two bottoms of nozzle supporting mass is used for being under the pressure directs into nozzle, and wherein certain corresponding resistance to compression ground, two bottoms constitutes.
Propose as a kind of replacement scheme, described nozzle supporting mass has the shape of disk, constitutes the oil content subchannel therein.A disk is the simple structure parts that geometry is favourable, and it can constitute on easily enough resistance to compressions ground.
In another kind of replacement scheme, described nozzle supporting mass constitutes with the form of one or more tubular arms, wherein passes each arm respectively and extends an oil content subchannel.Described nozzle supporting mass has a kind of simple especially and need the shape of short space in this embodiment of sedimentator, and especially when having only one or two arm to be furnished with a recoil nozzle respectively, this is normally fully enough.Look on the next door of tubular arm in a circumferential direction or the space that keeps between tubular arm can be advantageously used in the rotor of sedimentator at this.This point can realize a bigger internal rotor spatial volume for the given installing space that is used for sedimentator.
The rotatable supporting of described rotor can differently realize.In a kind of first embodiment, propose about this supporting, described rotor bearing one constitute a shell part, rigidity or hingedly be fixed on the axle on all the other shells, it passes rotor and it releasably supports and be centered in the sealing cover the inside of having settled by its upper end.This solution is a kind of structure of stablizing and carrying especially.Here under normal circumstances axle can be used as the service life structure member and is retained in sedimentator the inside.
Also can be used as replacement scheme and make described rotor bearing on the axle of a rigid element of a formation shell, this shaft extension is advanced rotor and is terminated by its upper end and the sealing cover compartment of terrain of having settled.Said axle has terminated or has exceeded this rotor in the rotor the inside and just terminated.Described rotor and/or sealing cover here can constitute more simply.Described axle here also can be under normal circumstances as service life structure member be retained in the sedimentator the inside.
A kind of the 3rd flexible program of described rotor bearing proposes, and described rotor supports by an axle journal respectively in bottom and top, and wherein said axle journal is the parts of rotor or the parts of shell and its sealing cover.Advantageously make internal rotor not have supporting device here.
For few frictionally supporting rotor, can be as use sliding bearing and/or rolling bearing knownly.
Described dirt captures parts and can constitute with different forms and mode.A kind of first organization plan regulation, described dirt capture parts by one axial bottom and axially top respectively fully or local that open wide, have one radially the hollow body of outer circle wall constitute, wherein in axial bottom, described nozzle supporting mass constitutes the bottom down to small part restrict rotor inner space at the assembled state of rotor, and wherein in the axial direction the described hollow body of portion by one independently, dirt fixing or that releasably settle captures the sealing of parts sealing cover.
In a kind of second organization plan of scheme as an alternative, described dirt capture parts by one cup-shaped, axially opened upper end, have one radially the hollow body of outer circle wall constitute, portion in the axial direction wherein, this hollow body by one independently, the fixing dirt that maybe can unclamp arrangement captures the sealing of parts sealing cover.
In the 3rd organization plan as another kind of replacement scheme, described dirt capture parts by a bell shape, axially the bottom fully or local that open wide, have one radially the hollow body of outer circle wall constitute, wherein constitute a bottom at the assembled state of rotor down to small part restrict rotor inner space at the axial described nozzle supporting mass in bottom.
A kind of the 4th organization plan is, described dirt capture parts by a jar shape, axial bottom and axially the top sealing, have one radially the hollow body of outer circle wall constitute.
Capture the tubular wall that the hollow body that can make described formation dirt capture parts in every kind of organization plan of above-mentioned four kinds of organization plans of parts additionally has an inner radial at dirt, it is particularly useful for strengthening dirt and captures parts.
Described torque-transmitting mechanisms can be arranged on the diverse location of rotor.A kind of preferred embodiment in, the torque-transmitting mechanisms that concurs that the driver part of described rotor and dirt capture parts is arranged on the inside, position, axial top of its inner radial.The advantage of this structure of described torque-transmitting mechanisms particularly in, described torque-transmitting mechanisms can see when parts are arranged on the driver part in that dirt is captured for the maintenance personal, and this helps to assemble easily and is avoided the assembling error.
The replacement scheme or the additional aspects that also can be used as above-mentioned embodiment are arranged on its axial lower portion the inside with the driver part of described rotor and the torque-transmitting mechanisms that concurs of dirt capture parts.The dirt that this layout of described torque-transmitting mechanisms not only can be used for axial lower open captures the parts embodiment, and can be used for the dirt capture parts embodiment of axial bottom sealing.When being positioned at the warp-wise outside for the described torque-transmitting mechanisms of this embodiment, produce the less power along driver part and the effect of dirt capture parts circumferencial direction here when transmitting a given torque, this can realize a kind of lighter torque-transmitting mechanisms embodiment.
For the embodiment of the driver part with arm body, described dirt capture feature bottom has a profile that axially overlaps the torque-transmitting mechanisms of the driver part arm, that concur with this arm, as to constitute rotor driver part and dirt capture parts.Described here driver part advantageously need not torque-transmitting mechanisms independently and captures at dirt torque-transmitting mechanisms there is constituted very simply.
The bottom profile that can also make described dirt capture parts as a supplement additionally is made of to engageable and out-of-gear being located by connecting the arm axle with driver part.Thus can by plain mode make dirt capture parts at the driver part epipodium to prevent axial slip.
To be positioned at oil internal rotor, that will be cleaned and to place rotation as far as possible effectively in order to make, also stipulate when rotor places rotation, described dirt captures parts portion's guiding and reinforced wall of having radially or substantially radially extending within it.Can realize thus that in addition dirt captures the mechanical consolidation of parts, this allows to use the material of lighter or thin-walled for dirt capture parts and/or moves with higher rotating speed.
In a kind of improvement project of the described above-mentioned last a kind of embodiment that freely sprays sedimentator, the inner radial end of described guiding and reinforced wall constitutes the parts of a dirt capture parts end of torque-transmitting mechanisms, and the torque-transmitting mechanisms that concurs of the driver part of described rotor and dirt capture parts is arranged on rotor radial inner portion the inside with extending at least a portion of body axial length.Make guiding and reinforced wall obtain another function in this embodiment, this is a kind of favourable high functional integration.
Preferably stipulate on the epitrochanterian location independent of sedimentator ground with torque-transmitting mechanisms, described driver part and dirt capture the torque-transmitting mechanisms that concurs of parts by can axially splicing and the many ribs profile that separates or profile of tooth or waveform or groove-tenon structure formation, look diametrically not respectively or to have a wall recessed.The embodiment of the torque-transmitting mechanisms that all provide captures a kind of simple axially-movable engagement and the disengaging engagement of parts with respect to driver part by dirt, wherein is delivered to dirt reliably in the torque that the described torque-transmitting mechanisms of engagement will be produced by driver part and captures on the parts.Having the recessed groove of wall-this torque-transmitting mechanisms of tenon embodiment and can also bear the power of radial effect simultaneously for torque-transmitting mechanisms.The above-mentioned guiding with driver part center tubes is connected by axially merging equally like this with reinforced wall, makes radial effect power to be transmitted to center tubes by guiding and reinforced wall.Obtain a kind of light weight rotor of stablizing and can carrying especially in this embodiment.
For the assembling that is operated in that makes the maintenance personal is simplified during rotor as much as possible, and in order to avoid also suggestion of assembling error as far as possible, the torque-transmitting mechanisms that concurs that described driver part and dirt capture parts constitutes by entering the inclined-plane and/or entering the tip self-alignly.
For a kind of economic as far as possible machinability that realizes dirt capture parts stipulates that preferably the hollow body that the dirt of described formation rotor captures parts is a kind of plastic injection piece of integral type.
The hollow body that scheme as an alternative, the dirt of described formation rotor capture parts be one by two plastic injection pieces splicings, best welded structure parts.Although the structure work in-process of double-body bike is bothersome slightly, can realize that more complicated dirt captures the moulding of parts.
Be plugged into together state at it and sufficiently prevent also regulation preferably of leakage of oil ground sealing each other for the driver part that makes rotor and dirt capture parts, capture contact site between the parts at the driver part of rotor and dirt respectively and at least one is set independently settles or the seal of integral type shaping.
Irrespectively preferably stipulate with the above-mentioned organization plan that freely sprays sedimentator for this sedimentator that freely sprays, in order to produce two lubricating oil shuntings, the lubricating oil stream that is input in the sedimentator is divided into two according to flow shunting given, that preferably guide by two definite throttle position in sedimentator, one of them is shunted and be input to driver part and its recoil nozzle under pressure, and another shunting is input to dirt capture parts by at least one with entering the mouth no pressure.The oily flow distribution of carrying by making is avoided being used to distribute and adjust the mechanism that oil flows according to flow in the sedimentator outside in sedimentator inside.This also helps compact sedimentator version.In addition by becoming shunting to determine the flow proportional of two shuntings targetedly oily flow distribution according to flow harmony ground.Can influence the rotor driving power that produces the rotor drive part on the one hand thus.Exist on the other hand in desired mode and influence the possibility of oil in the holdup time of internal rotor.Can determine to move important parameters by simple mode thus, and also can structurally change where necessary for freely spraying sedimentator.
Preferably described two throttle position are arranged on the driver part the inside of sedimentator at this.Its special advantage is can not produce functional fault for the lubricated of internal combustion engine when lacking dirt capture parts unintentionally.Keep lubricating oil pressure fully, because in dirt capture parts, do not have pressure to fall.
The upper bearing of a throttle position by driver part in described two throttle position constituted with a definite gap size, wherein the lubricating oil shunting can be input to dirt and capture parts by this throttle position.Need not a structure member that independently is used for throttle position here; Guaranteed good bearing lubrication simultaneously.Advantageously throttle position is produced an automatically cleaning effect by two mutual counterrotating parts of bearings here in addition, making this throttle position thus is insensitive for dirt.
In this regulation preferably in another organization plan, the described shunting that is input to driver part captures the shunting of parts according to flow greater than being input to dirt.By the fast starting and the high rotating speed of this preferred distribution assurance sedimentator rotor, guarantee simultaneously that wherein through-flow internal rotor and its dirt capture the long holdup time of the shunting of parts.Fast starting with a rapid rotating speed rising realizes that thus promptly before rotor starting, this rotor does not at first also contain oil, and therefore easier starting.When to the sedimentator transferring oil time, the bigger shunting of oil arrives the driving nozzle at once then, and light rotor is quickened, and dirt capture chamber just lingeringly is full of.This organization plan helps the good validity of sedimentator separate little dirt particle, especially carbon black from the lubricating oil that will be cleaned aspect.
In order to obtain one in sedimentator inside in simple as far as possible structure aspect the lubricating oil conveying, described a kind of preferred structure scheme regulation of freely spraying sedimentator, described lubricating oil is not only realized for driver part but also for all axial axle journal that passes through axle or bottom from the bottom of dirt capture parts to the conveying of sedimentator.As known, lubricating oil can for example pass through the realization of sedimentator pedestal or another structure member to axle or to the conveying of axle journal, and it for example is the parts of an oil strainer device.
Scheme as an alternative, described lubricating oil to the conveying of sedimentator for driver part axially from the bottom axle journal by axle or bottom realize, axially realize separately and capture parts from top for dirt.Realize a kind of bigger structure free degree by this additional embodiment, this helps a kind of more favourable solution in some application scenario of freely spraying sedimentator.
For above-mentioned all embodiments of sedimentator that freely spray, regulation preferably in another organization plan, the shunting of described lubricating oil for dirt capture parts in the axial direction portion radially from inside to outside with one around face spray or the form of a plurality of distribution single injection in a circumferential direction imports to dirt by at least one correspondingly configured inlet and captures the parts the inside.This organization plan is responsible for making lubricating oil to capture at dirt looking on the circumferencial direction of parts and is arranged on equably on these dirt capture parts with distributing.Make lubricating oil leading thread far away as far as possible to outside conduction at the same time, centrifugal force is effective especially there.Realize lubricating oil in addition thus in the long as far as possible through-flow path of axially passing through rotor, this same promotion by the centrifugal action eliminating impurities particle in the rotor.
If the desired even distribution of the not responsible lubricating oil shunting of described inlet on the rotor circumference direction, then portion can be provided with at least one and insert lubricating oil evenly distribution on the circumferencial direction of dirt capture parts that parts are used to make inflow inside dirt captures parts in the axial direction.
In axial bottom and inner radial the lubricating oil outlet of at least one cross section greater than entrance cross-section is set on rotor according to another improvement project.The export structure scheme that here provides is responsible for making in rotor and does not produce the hydrodynamic lubrication oil pressure except the lubricating oil pressure that produces by centrifugal force.
Also stipulate, on the bottom surface of radially outer at rotor of outlet and/or on an end face that is positioned at the sedimentator shell position below the rotor, be provided with one and turn to muscle structure or a blanking disc, it make no force feed oil content stream from outlet be forced to one that turn to, with the rotor and the trend of separating with oily jet that each recoil nozzle produces.Guarantee that thus the driving mechanism of described rotor is not subjected to the oily flow disturbance from outlet, and does not reduce its validity.Describedly turn to muscle structure and/or blanking disc in the position below rotor, to be responsible for making not have oil stream that pressure discharges and separate from the oily fluidic spaces that the recoil nozzle is discharged from rotor.Guarantee the property in full force and effect of rotor recoil nozzle driving mechanism thus constantly.
In addition as mentioned above, described driver part prevents from upwards to pull out.This fixing fixture of preferably locating or tightening by or being tightened on the axle is particularly realized.Can be fast and settle this fixture simply, and it satisfies its contemplated function with the reliability of height.There is this possibility in addition,, the driver part of rotor can be taken off from sedimentator in case of necessity if under contingent failure condition, must expect cleaning or change this rotor.
As mistake described above, although described torque-transmitting mechanisms will capture parts to dirt by the transmission of torque that driver part produces, but design them consciously like this, make them be easy in the axial direction merge and separates, wherein be provided with special entity with respect to the axially-movable of driver part in order to prevent or to limit dirt capture parts.In order to realize this special entity, described dirt captures component axial and axially has a stop surface respectively in the bottom surface at end face and sealing cover, and dirt captured the axially-movable of parts with respect to driver part when their mutual actings in conjunction prevented or be limited in the arrangement sealing cover.The advantage of this organization plan is that the restriction of cancellation axially-movable when taking off sealing cover can not have other dirt to be captured component axial then with interfering and takes out from the sedimentator shell unlimited by taking off sealing cover.
Replacement scheme as above-mentioned embodiment, one in the axial direction portion and axle can unclamp the backstop that is connected, radially outward protrude in axle and capture parts at axially bottom surface and dirt and have a stop surface respectively at axial end face, their mutual actings in conjunction prevent or are limited in sedimentator dirt in service and capture the axially-movable of parts with respect to driver part.Replace sealing cover to have independent structures parts in this embodiment, i.e. backstop, stop surface, this can realize a kind of simpler frame mode of sealing cover, for example a kind of plastics sealing cover, it need not one and is used for the required metal insert of stop surface.
For the quantity that makes essential single parts keeps less advantageously regulation, described fixture and backstop are merged into a structure member or are incorporated in a structure member the inside.
Upwards act on the sedimentator embodiment that epitrochanterian power produces in the axial direction on important circumference for being in operation, the present invention preferably advises, capture at dirt between the axial bottom surface of the axial end face of parts and sealing cover another bearing is set, it prevents or is limited in, and dirt captures the axially-movable of parts with respect to driver part when settling sealing cover, and bear the power that axially makes progress that dirt captures parts, need not the rotor braking that is in operation at this.
The feature of described another extraordinary repair close friend's who freely sprays sedimentator organization plan is, described dirt captures parts to have respectively in axial bottom surface at axially end face and sealing cover and can mesh each other and the online structure of out-of-gear coupling, detent mechanism preferably, they do not contact when settling sealing cover each other, and they when taking off sealing cover with condition that driver part separates under axially upwards drive dirt and capture parts.In this organization plan, when taking off sedimentator shell sealing cover, drive dirt simultaneously and capture parts, this obtains a kind of special shirtsleeve operation when the maintenance sedimentator.Only old dirt capture parts need be separated with sealing cover for new dirt capture parts are installed, and new, clean dirt capture parts are connected with sealing cover, preferably the location.Can simultaneously dirt be captured the additional installation step of parts ground on the sedimentator shell and reconnect into a complete rotor by sealing cover is placed in then with affiliated driver part.Do not disturb described rotor in the operating rotation of sedimentator by the online structure of coupling,, make the online structure of coupling of two parts when settling sealing cover, not contact mutually because they constitute like this and are arranged on like this on sealing cover and the dirt capture parts.Therefore do not produce an interference and the online structure friction of coupling that cause wearing and tearing in that sedimentator is in service.Only the online structure of described coupling just is in contact with one another when taking off sealing cover.
Also can be furnished with one subsequently according to sedimentator of the present invention in order to make existing internal combustion engine, the present invention also proposes, described driver part and dirt capture parts and have a kind of moulding and size at it aspect the coefficient parts of shell, their allow with driver element and dirt capture parts be installed to existing, be furnished with inside the sedimentator of a traditional rotor at present.Advantageously realize being equipped with again with minimum expense thus.
Capture and preferably stipulate aspect the parts easily removing the sedimentator dirt that loads by dirt particle, described dirt capture parts are no metals, and constitute plastics that dirt captures parts and be single, a kind of callable plastics preferably of kind, and can unharmful substance or the burning of rare pest quality.
The described sedimentator that freely sprays is a kind of cleaning device in many application scenarios, and it is in the auxilliary stream of an oil; This point often is this situation when the cleaning IC engine lubricating oil for example.In order in an attached stream, to use and freely to spray sedimentator and stipulate aptly, in a passage that lubricating oil is input to sedimentator, a minimum pressure priming valve is set, just it only surpass one can be given in advance the upstream end oil pressure allow oily the input later on.Guarantee that by this sedimentator structure when providing oil on enough circumference and with enough pressure, sedimentator is just through-flow by oil.Guarantee for internal combustion engine thus, before the lubricating oil shunting is by the sedimentator conduction, realize the lubricated of all lubricated positions of internal combustion engine.
Another is for the special compact structure form of sedimentator with for its first as far as possible simply assembling advantageously, described sedimentator is a part that comprises the module of another auxiliary device at least of internal combustion engine, especially oil strainer and/or oil cooler, but its flange under the condition of setting up necessary through-flow connection is connected on the internal combustion engine.
Also stipulate as the lubricating oil centrifugation device according to the sedimentator that freely sprays of the present invention for using according to the present invention in addition, described sedimentator moves at an auxilliary stream that leads to the oil strainer that is arranged in main flow, and the auxilliary stream of through-flow sedimentator comprises 10%, best 5% of main flow volume flow at most.From main flow, draw and the auxilliary stream by sedimentator conduction is so little in this organization plan, make the lubricating oil of affiliated internal combustion engine lubrication position not to be supplied with to exert an influence.But this auxilliary stream little on volume is enough to be used in separating little dirt particle, especially carbon black effectively in sedimentator inside on the other hand, guarantees more cleaning, the less granular state of IC engine lubricating oil in the whole time period of changing oil for twice between safeguarding thus.
Feature according to another organization plan of sedimentator of the present invention is, described sedimentator comprises the axle at a center for rotatably mounted rotor, it is hollow on the part of its length at least, and constitute an intercept of oily input channel, the valve body of a prestrain on closing direction of a minimum pressure valve axially is set in this intercept slippingly, this valve body is stretched from axle, and it is outside that a seal head of this valve body is positioned at axle, and one constitutes on the sedimentator case member of a bolster with the coefficient valve seat of seal head, and described oily input channel is passed this case member and extended.
It is outside to be positioned at axle by the seal head that makes minimum pressure valve, can use an axle with less external diameter.This point allow to be used the lower bearing with corresponding sedimentator rotor than minor diameter, and this helps realizing small friction in this lower bearing, and realizes high rotor speed for a given driving power thus.Minimum pressure valve does not need extra structure space in sedimentator inside simultaneously, guarantees a kind of compact structure form thus.
Another organization plan regulation of above-mentioned sedimentator, described valve body multi-hull type ground is made up of interconnective single parts, especially seal head, a handle bar and a guiding end block.For the handle bar that the hollow parts that passes axle extends, a less diameter is just enough.It is outside to need a larger-diameter seal head to be positioned at axle for its function, therefore can not influence the size of shaft diameter thus.Valve body by multi-hull type can use optimal material respectively for single parts, can realize the best-of-breed functionality of minimum pressure valve thus by simple approach.
As its replacement scheme, described valve body is integrally constituted.Especially realize the machinability of the cost economy of valve body by this organization plan.
Described feature of freely spraying another embodiment of sedimentator is, described driver part comprises the body at a center, it surrounds a central shaft in the compartment of terrain under the condition that forms a ring passage that is used for the oil input, rotatably mounted driver part on this axle, and in the upper end position of the ring passage between the oil-in that the upper bearing and the dirt of driver part captures parts a shading ring is set, it or inner radial are connected on the axle, and perhaps radially outer is connected on the body.
Avoid disadvantageous big oil stream by the bearing under the shading ring protection, big oily stream may cause bearing running hot.But guarantee the enough lubricated of upper bearing simultaneously,, on each mutual opposed side, also vacate an oily passage that is used for the enough oil masses of bearing lubrication thus because this shading ring or inner radial or radially outer connect.Being connected advantage additional in the embodiment on the body at the shading ring radially outer is, constitutes a dirt capture angle that is positioned at radially outer, makes the bearing of dirt particle away from shading ring top.
Described feature of freely spraying another embodiment of sedimentator is, described sedimentator comprises the hollow shaft at a center, its hollow inside constitutes an intercept of oily input channel in one first axial position, and in one second axial position, constitute an oily passing away, restrictive axial is provided with a prestrain on closing direction of a minimum pressure valve slippingly in the hollow interior of axle, with coefficient first valve body of valve seat, in valve body, constitute an oily passage, and second valve body and this oil passage acting in conjunction of a prestrain on closing direction of an overvoltage termination valve.
In this embodiment, the described sedimentator that freely sprays has a valve cell, and it comprises the function that a minimum pressure valve and overvoltage stop valve with unusual compact structure form.At this valve body that advantageously only needs two activities, this helps the compact structure form and simply assembles and obtain reliable functioning.Advantageously so compact in this this version, make whole valve gear to be placed in to be used for the hollow interior of the axle of sedimentator rotor, and axle needn't have king-sized external diameter.Be responsible at this minimum pressure valve, when on the sedimentator inlet, having a definite minimum oil pressure, realize that just the oil by sedimentator flows.If oil pressure is lower than this minimum pressure, then closes minimum pressure valve, and do not have oily stream to pass through sedimentator.Described overvoltage stops valve and is responsible at one too high when entering the oil pressure of sedimentator, at least one oil content stream is discharged by a relief passage with the through-flow path of a weak point, this relief passage captures the guiding of parts next door at the driver part and the dirt of rotor, realizes release rapidly thus.Only otherwise reach and make overvoltage stop the pressure that valve is opened, overvoltage stops valve and just keeps closing.The valve body of the only limited axial slip of minimum pressure valve is responsible in its open mode, closes the relief passage simultaneously at this state.
In this another organization plan that freely sprays sedimentator, described first valve body and the prestrain of second valve body on its closing direction produce by a unique spring.This embodiment obtains a kind of simple especially and version of saving the space.
Scheme respectively produces described first valve body and the prestrain of second valve body on its closing direction by self a spring as an alternative.Exist a bigger active force to change in this embodiment, they will act on two valve bodies as prestrain.
According to another organization plan a kind of sedimentator that freely sprays is proposed, it is characterized in that, described sedimentator comprises the hollow shaft at a center, its hollow inside constitutes an intercept that is used for driver part and is used for dirt capture parts of oily input channel in one first axial position, and in one second axial position, constitute an intercept that only is used for dirt capture parts of oily input channel, thereby restrictive axial is provided with a prestrain on closing direction of a minimum pressure valve slippingly in the hollow interior of axle, with a coefficient valve body of valve seat, and in valve body, constitute an oily passage with definite cross section, the opening of its seal receptacle end is positioned at radially outer, and is positioned at one and the coefficient sealing profile of seal receptacle downstream of valve body.
Advantageously make valve body be divided into the mechanism of two shuntings as the oily stream that is used for to be transported to sedimentator in the sedimentator this freely the injection, one of them shunting is transported to the driver part with recoil nozzle, and another shunting is transported to the dirt capture parts that are used to clean.Constitute a definite cross section at this oil stream by valve body, one of its conduction to dirt capture parts can be given in advance oil volume stream.
If described valve body is positioned at its closed position, then it not only flows by the end of the oil content of driver part fully, and captures the oil content stream of parts fully by the end of dirt.Prevent that thus the closed condition at minimum pressure valve from making the dirt of an oily circulation stream sedimentator capture parts, and in possible mode dirt particle is flowed there and be discharged to the lubricating oil the inside of having cleaned.
A kind of embodiment of the replacement scheme as above-mentioned sedimentator proposes a kind of sedimentator, it is characterized in that, described sedimentator comprises the hollow shaft at a center, its hollow inside constitutes an intercept that is used for driver part and is used for dirt capture parts of oily input channel in one first axial position, and in one second axial position, constitute an intercept that only is used for dirt capture parts of oily input channel, restrictive axial is provided with a prestrain on closing direction of a minimum pressure valve slippingly in the hollow interior of axle, with a coefficient valve body of valve seat, and between the inner periphery of the excircle of valve body and hollow shaft, constitute an oily passage with definite cross section, the opening of its seal receptacle end is positioned at radially outer, and is positioned at one and the coefficient sealing profile of seal receptacle downstream of valve body.
By this as an alternative the solution of scheme realize the advantage identical with above-mentioned sedimentator, wherein difference only is, is transported to oil content stream that dirt captures parts now and conducts by a definite circumferential weld between the inner periphery of valve body excircle and the hollow shaft that directs into valve body when opening minimum pressure valve.If described valve body is positioned at its closed position here, then it is except also capturing the oil content stream of parts fully by the end of dirt by the end of the oil content stream of driver part.
Another according to feature of freely spraying sedimentator of the present invention is, described dirt captures the bottom of parts and is furnished with the fracture that radially distribution is provided with circumferencial direction, and below the bottom that disconnects with axially spaced-apart ground, bottom and the blanking disc of a sealing is set on nozzle, it is the part of driver part, perhaps capture in the parts on the top by the bottom of its sealing at dirt a central bottom is set, it is furnished with radially the fracture that distributes and be provided with circumferencial direction.
Rotor radial is only observed from outside to inside be full of oil in its radially outer part for this sedimentator that freely sprays, the solid rotor of mass ratio that rotor is comprised be positioned at oil wherein is littler, and this obtains a higher rotating speed when given driving power.This higher rotating speed is responsible for quickening dirt particle is separated from lubricating oil by centrifugal force.If the many like this leading threads of the dirt particle that precipitates in the radially outer position of internal rotor group are to inside growth, make its cover one of fracture radially bead of ragged edge, lubricating oil is discharged by radially inner nearest fracture bead, wherein can make again and have only a limited oil mass to be included in the rotor the inside, but this superiority of increase of rolling into a ball along with the dirt particle of growth diminishes gradually.
Above-mentioned a kind of improvement project regulation of freely spraying sedimentator, described bottom or central bottom of being furnished with fracture is orifice plate or sieve plate.
Additionally can on bottom or central bottom, lay one can through-flow oil the material layer of its fracture of covering, the material layer of making by felt or fabric preferably.Although this material layer can through-flow lubricating oil, prevent by bigger dirt particle part or dirt particle regiment headquarters branch.
