At present, the cooling of gear-box is the most air-cooled, in some low speed, the less gear-box of pinion ratio, when design even without considering its radiator structure.Dispelling the heat in the air-cooled surface depending on gear-box, when being necessary, can arrange a number of radiating fin by increasing heat radiation area with auxiliary heat dissipation.In the gear-box of more severe easy heat, even gear-box arranges water jacket, to improve cooling effect further.But using under environment specific, limited by the source of water, water-cooled becomes unrealistic, such as western China, even if electromotor, also have to use air-cooled.And water-cooling structure is relatively complicated, thus, air-cooled structure is with the presence of its unique value.
In some applications, by changing the trend of oil groove and increasing the area of oil groove, to increase the cooling to bearing, this kind of structure can effectively improve the cooling capacity of bearing, but the cooling capacity that gear-box is on the whole does not improve.
Typically, in Chinese patent literature CN104235332A, have employed the hollow fin of rectangle, and the corrugated tube arranging S type in fin belongs to the form of increase area of dissipation to improve radiating efficiency with the lubricating oil that circulates, this kind of structure.But corrugated tube belongs to consumable accessory, especially in the case of temperature is higher, (such as 70 degrees Celsius) are easier aging.It further provides air-cooled structure, offers passage the most on a heat sink, and its essence remains by the way of increasing area of dissipation to improve radiating efficiency.
In addition, such as Chinese patent literature CN103912666A discloses a kind of from radiation tooth roller box, it is provided with fixing fin on gear-box, i.e. increasing area of dissipation, structure is relatively easy, but comparatively speaking, relative to the gear-box being not provided with fin, its radiating efficiency is higher, even if but relative to previous patent documentation, its radiating efficiency is relatively low.
Comparatively speaking, the commonly used cast structure of gear-box, the direct casting of fin, maintainable poor, then disclose one such as Chinese patent literature CN204114085U on gear case body, offer detent, heat sink strip is set in detent, there is dismoutability.Natural, split in conjunction with structure can produce the blocking-up of thermally conductive pathways, and affect radiating efficiency.

Detailed description of the invention
With reference to Figure of description 1, routinely, gear-box includes casing 1 and case lid 2, and both are typically attached by bolt, matchingly, as shown in Figure 3 according to the mounting bolt hole 18 of certain rule distribution.
Gear-box needs to consider to seal, and configures a pair alignment pin by needs, for the assembling of casing 1 with case lid 2, pin-and-hole 16 as shown in Figure 3, is used for squeezing into alignment pin, carries out the assembling of casing 1 and case lid 2 the most again.The assembling structure formed is found in Fig. 1, in order to understand reaction radiator structure in Fig. 1, dispenses the securing members such as bolt, and omits the gear in gear-box, to manifest radiator structure and layout thereof.
Two technical problems are mainly solved in the present invention, first technical problem is that heat dissipation problem, relate to interior air-cooled structure and flow-disturbing thermal component 3 as shown in Figure 4, another wear problem then related to, i.e. detracted by spoiler 31 and produced by the agitation of gear mesh lubricating oil, the deposit bottom casing 1 is mixed into the problem of lubricating oil, thus reduce abrasive wear.
Can be seen that from the structure shown in Fig. 1, this type of gear-box has the arcuate structure on case lid 2 due to the big footpath of coupling gear, its structure is done certain correction by the present invention, but from profile baseline, has added the space shared by the gear-box of air-cooled structure and do not significantly improve.
Additionally, for conventional understanding, gear-box typically direction based on its main shaft, the direction at main shaft place is generally width, the horizontal direction vertical with the direction is its length direction, except there is the application scenarios of bevel gear, worm and gear, but does not affect the understanding in the general orientation of gear-box.
And for casing, in casing be relative outside casing.
First technical problem is the most first described, the radiator structure of gear-box reality as shown in figs 1-9, especially accompanying drawing 1,2,5 and 6, in figure, the top at the case lid 2 of gear-box is provided with air inlet 21, is used for introducing cold air, natural, can be that air inlet 21 configures blower fan, owing to need not the highest blast, the axial flow blower that air quantity volume ratio is bigger can be used, axial flow blower is relatively simple for structure, also adapts to pipeline configuration.
Cold air is wanted to be introduced by external structure, provides only air inlet herein.When using pipeline air-supply, can consider that lubricating oil passes through air inlet 21 and spills to a certain extent, when especially configuring relatively long pipeline for air inlet 21.
If using blower fan air-supply, it is recommended to use axial flow blower, the wind that axial flow blower is sent will not significantly increase the temperature of introduced wind.
As it is shown in figure 5, in figure, the air outlet structure being positioned at middle part is positioned at the centre position of two air inlets 21, relatively increases cooling wind path in gear-box, can significantly more efficient raising cooling effect.Additionally, air inlet 21 to be arranged on the top of case lid 2, it is introduced from above into cold air, formation down current, and the meeting generation convection current that hot-air is relative, and produces ascending air, thus cooling effect can be more preferably.
Wherein, air outlet structure includes the holding part of a tubulose, is specifically found in Fig. 5, the main body of the oily filter core pilot hole 25 shown in Fig. 5 be one columnar structured, one end connection air of this holding part, for being provided with one end of flange 26 in figure, the other end is communicated in case lid 2 by oil and gas import 27.
Wherein, about holding part, its on the whole can together with case lid 2 casting, oil and gas import 27 therein as shown in Figure 6, can be arranged on the bottom of holding part, and in certain embodiments, oil and gas import 27 is directly configured to the inner mouth of pipe of holding part.
In order to be conducive to the assembling of oil filter core 6, under conditions of being not provided with the such as oily filter core assembling screw rod 23 shown in Fig. 5, can arrange oil-gas room 22, the axial port of oil-gas room 22 is docking port 24, and the screw thread of end can be used to carry out the assembling of oil filter core 6.
After oil filter core 6 crosses oil strain, drip from oil filtering bodies 61, be then refluxed for gear-box.
Therefore, oil filter core 6 mainly has two kinds of assembling modes, a kind of is threadeding by the screw thread of termination and the docking port 24 in Fig. 5, another kind is that the oily filter core assembling screw rod 23 by being arranged on assembles, now can retain oil-gas room 22, the docking port 24 of this oil-gas room 22 is for the location of oil filter-core of filter 6 the inner.
Accordingly, it is seen that in the structure shown in Fig. 8, in figure, the left end of oil filter core 6 is that it is inner, and right-hand member is its outer end.Two major parts are generally comprised for oil filter core 6, one is skeleton, another is oil filtering bodies 61, wherein skeleton includes that inner support 63(is usually circular ring structure), support arm 62(be typically provided centre bore, i.e. screw rod via 67 shown in Fig. 9, for the assembling of oil filter core 6), and connect inner support 63 and the cartridge type support of support arm 62, wherein cartridge type support is that porous plate winding forms, directly as the supporter of oil filtering bodies 61.
Oil filter core 6 can directly use the filter element of oil formula orbiting vane vacuum pump, without carrying out special design.
Oil filter core 6 assembles with holding part coaxial line, and present in Fig. 9, screw rod via 67 does not represent oil filter core 6 and need not sealing-in at this end, on the contrary, after this end is compressed by clamp nut, can play the sealing function adapted.To this structure, may refer to the assembling structure of oil formula orbiting vane vacuum pump upper filter.
In Fig. 8, oil 6 sections of the inners of filter core are the inner supports 63 shown in figure, are provided with sealing ring 64 on inner support 63, realize, for coordinating with the docking port 24 shown in Fig. 7, the sealing that end face is connected.
Additionally, as shown in Figure 8, in figure, inner support 63 is additionally provided with counterbore, based on this counterbore, forms the clamp to docking port 24 end face bulge loop, it is achieved simple labyrinth seal, also is able to effectively realize relatively reliable positioning to oil filter-core of filter 6 simultaneously.
Obviously, in order to meet the discharge of gas, between oily filtering bodies 62 and the holding part inwall of oil the filter core 6 and outer end of oil filtering bodies 62 and holding part inwall should leave gap, this section is gap section, by this gap, gas can be discharged, and also leaves the passage gaps that the lubricating oil of backflow is certain for simultaneously.
In order to reduce the interference of backflow, the holding part being positioned at gap section has oil return opening 28, and the oil circuit being configured at oil return opening 28 extends under gear-box liquid level, thereby structure, and oil gas will not directly be scurried out from oil return opening 28.
For oil level, routinely, as it is shown on figure 3, right part is provided with oil ga(u)ge hole 15(omission oil ga(u)ge in figure), the lubricant level in gear-box can be checked by oil ga(u)ge.
As it is shown in figure 1, configure air intake installation for the air inlet 21 shown in Fig. 1 owing to needing, such as blower fan, it is only necessary to consider the air inlet spatter property of blower fan side.
About the gear-box under gear-box, especially fully loaded transportation condition, it is usually fixedly installed, such as lathe, and lathe vibrations are not enough so that lubricating oil overflows from air inlet 21.
Additionally, the oil level typically ratio in gear-box is relatively low, typically floods maximum gear bottom and be not more than at 1/3rd, for little gear, routinely, oil tanker can be dipped in by increase, to provide the lubrication of little gear.
Owing to the Lubricating Oil bit comparison in gear-box is low, under conditions of not being severe especially using environmental vibration, air inlet 21 can not be done specific Protective Design.
In some embodiments, the axis horizontal of described holding part, because there being the setting of oil filter-core of filter 6, it is not necessary to considers that lubricating oil directly spills at holding part.
Relatively, the axis of air inlet 21 is obliquely.In certain embodiments, air inlet 21 axially can be forward.
Finding through overtesting, although can reduce difficulty of processing forward, and cooling effect is also fine, but comparatively speaking, cooling effect obliquely can more preferably, and the especially outlet of air inlet 21 rolls the most better to air outlet structure.
About the axis of air inlet 21, to become 15 degree to be advisable with vertical plane, i.e. deflection 15 degree.
Preferably, as it is shown in figure 5, in figure, oily filter core pilot hole 25 as described holding part is positioned in the middle part of the end face of case lid 2, and inlet gas 21 has two, two air inlets 21 are symmetrical about the vertical midship section of holding part, and thereby structure can play more preferable cooling effect.
Two air inlets 21 can share a source of the gas, is connected by adaptive pipeline.
In some preferred embodiments, as in figure 2 it is shown, 21 be provided with a check valve and be positioned at the filtering bodies 5 for gas filtration of check valve prime in described air inlet.
The produced loss of lubricating oil splash mainly avoided by check valve, even if there being parts of lubricating oil to splash out, also without entering directly into the trachea of cooling gas, thus can be reduced the pollution to cooling air machinery by the stop of filtering bodies 5.
Further, described check valve is diaphragm check valve 4, and diaphragm check valve 4 actually has on the hole of mouth again and covers a tunic, check valve 4 is that pressure-bearing is opened in the side of non-overlay film, relative, in the side with film, can make membrane attaching after pressure-bearing on opening, thus cannot turn on.
Diaphragm check valve 4 structure is very simple, and cost is the lowest, and its axial dimension is the least simultaneously, is conducive to arranging on the gear-box of structure relative compact.
Describing the technical problem of second aspect the most again, this technical problem relates to two aspects, and an aspect remains heat radiation, and another aspect is then to reduce abrasive wear.On a pair flow-disturbing thermal component 3 that emphasis is joined by casing 1 in fig. 2.Additionally, thereby structure also solves the cleaning problem of a beyond thought problem, i.e. casing.Make an explanation the most successively.
Specifically, as it is shown on figure 3, in figure, have the via 13 of the rectangle being communicated in case in the long wallboard bottom of casing 1 liang of gear-box, position of opening should avoid the profile of gear, it is to avoid as described hereinafter and the spoiler 31 interference to gear.
Two assembling motherboards 33 are provided, each via 13 i.e. configures one and packaged joins motherboard 33, assembling motherboard 33 is assemblied in corresponding via 13 by releasable connection, here releasable connection is that bolt connects, sealing for facade, it is not necessary to need encapsulant to seal, can also meet required sealing grade by accurate composition surface assembling, especially lubricating oil generally possesses certain viscosity, is easier to seal than water.
The via 13 of sealing after assembling with to(for) motherboard 33, on the one hand can provide sealing medium, such as stop-leak compound, on the other hand can provide seal member, such as rectangular seal, it is achieved the liquid-tight envelope of lubricating oil.
As shown in Figure 4, the spoiler 31 being provided with on the spoiler 31 extended in casing 1 of level, and two assembling motherboards 33 in figure on assembling motherboard 33 is opposed, leaves gap between the end face that opposed spoiler 31 is relative.
Gear-box is in operation process, abrasive dust can be produced, and along with oil ageing, can produce deposit, abrasive dust and deposit or impurity typically can be deposited on the bottom of casing 1, but the gear in gear-box usually dips in oil lubrication, lubricating oil can be produced agitation, and make abrasive dust, deposit, impurity be mixed in lubricating oil, and it is brought into the field of conjugate action of such as gear pair, and easily produce abrasive wear.
As shown in Figure 4 spoiler 31 agitation of gear can be produced must barrier effect, reduce such as abrasive dust and be mixed in lubricating oil, thus reduce the abrasion of gear.
One beyond thought problem is, clears up casing 1, but after removing spoiler 31, come out from side in the bottom of gear-box 1, is very beneficial for the cleaning of gear-box 1 after being originally used for the replacement of spoiler 31 by removable structure or be used for removing spoiler 31.
Monolayer spoiler 31 can play certain flow-disturbing effect in principle, i.e. bridging effect, arranges multilamellar spoiler 31 and seems that comparison is unnecessary, but finds through experiment, although multilamellar spoiler 31 does not has particularly apparent lifting to improving flow-disturbing effect, but still has relatively good castering action.
For its mechanism, it may be possible to the structure of layering, being also layered by lubricating oil, interlayer is harassed and is further reduced, thus plays extraordinary flow-disturbing effect.
Assembling structure about flow-disturbing thermal component 3, as shown in Figure 4, the inner face (referential, has strict differentiation inside and outside casing on the basis of casing 1) at described assembling motherboard 33 is provided with assembling shoulder 34, as shown in Figure 4, assembling shoulder 34 is the rectangular slab adapting to via 13.
Correspondingly, described via 13 is then provided with counterbore, as it is shown on figure 3, can significantly find out in figure, via 13 has step, correspondingly, is locating shoulder 12 at this counterbore and the body transition of via 13.
And then, assembling shoulder 34 is positioned locating shoulder 12 in the normal direction of assembling motherboard 33.
