Isolating ring preferably uses as the spacing washer between two adjacent in transmission shaft segment each other gears.It is also conceivable to, isolating ring uses as the spacing washer between gear and another transmission component, and another transmission component is such as gear housing, axle chamfered edge, bearing etc.Gear can be not only such as be fixed in transmission shaft segment or with transmission shaft segment Integral design and then relative to driving the non-rotatable gear of shaft segment by press fit, and can be rotatable gear in driving shaft segment.Latter case is as being called escape wheel or free pulley and being often arranged in transmission shaft segment by sliding bearing is rotatable.It is also conceivable to, spacer sleeve is set between the gear be arranged on regularly in transmission shaft segment and free pulley.
In addition isolating ring makes other any transmission component such as plate-like group or the drive bearing be arranged on transmission shaft, shaft segment or like keep certain distance, and/or is also supported on gear-box or axle chamfered edge at this.It is also conceivable to, isolating ring makes two tilting ball bearing devices mutually clamped such as in main transmission, keep certain distance.
Isolating ring short time or be subject to high axial force constantly in the layout determined.If isolating ring by impacting force such as with gear or the parts that form with other transmission components in compress time bear load, this axial force such as acts on isolating ring when assembling.This assembly force is in the order of magnitude of 60-80N when assembling.This isolating ring often bears and axially loads constantly between the tilting ball bearing of clamping.For this application, isolating ring must axial high capacity ground design.
Therefore JP11-303947AA discloses a kind of isolating ring, it around at least one transmission shaft segment, and makes at least one remain at a certain distance in the shaft segment of live axle relative to rolling bearing with the transmission component of gear forms at this on the circumference of spin axis.Isolating ring has and spin axis portion's section in the same way, and described portion section has hollow cylinder shape.Circular cylinder is designed to columniform in this case.US7,036,391B2 disclose the two kinds of isolating rings be made up of cylindrical portion section in the bearing arrangement of the axial grip of transmission device.
Profile is interpreted as the lines of the main body limiting isolation ring portion section around in this case, and observer's these lines when watching these sections set off out from background.This be it is also understood that to the view seen from different directions, observer can be made to determine the basic shape of matrix and not consider details.These details about overall profile be recess or projection or recess covered on visual direction as hole, these recesses again give the profile accurately seen truly, but these profiles do not change the essence of body.Therefore basic shape and the profile of hollow cylinder to be installed after radial flange, after inside and outside introducing annular groove or had all the time after introduction hole or recess from the teeth outwards to such as annular or polygonal hollow cylinder.Polygonal also can have bight, and this bight is with recessed or convex radius rounding.
Summary of the invention
Therefore the object of the invention is to realize a kind of isolating ring, itself function of unity and can manufacturing economical.
This object realizes thus, and namely described isolating ring is the parts be made up of sheet material.
A design proposal of the present invention proposes, and this isolating ring is designed to shell-like tensioning member.Another design proposal of the present invention proposes, and this isolating ring is made up of sheet material.Described isolating ring is such as made by the sheet material of annular curved, its crooked end by phase mutual designation and shape in locking manner, force closure ground or material be connected to each other in locking manner.
Can very accurately manufacture according to isolating ring of the present invention.Can when by stretch, shear or bending time additionally do not consume produce different drip moldings.Therefore described parts are particularly advantageous relative to prior art at cutting manufacture view, because in cutting manufactures, extra drip molding such as recess and flange are merely able to as turning, plane and milling and only to be manufactured with repeatedly material removal by bothersome material removal.
Can be lighter than the solid torus of prior art according to isolating ring of the present invention, especially when the sheet metal thickness of isolating ring is less than the bridge joint size between the inside envelope contour and outer envelope profile of isolating ring.Inner envelope contour is such as described by internal diameter in the ring of solid design, and outer envelope profile is described by external diameter.In this case, bridge joint is of a size of the half of the difference of external diameter and internal diameter.For bridge joint size that is cylindrical and non-cylindrical parts can be understood as on the base of isolating ring with norminal size, the outside dimensions of driving shaft segment of being surrounded by isolating ring and with norminal size, distance between each outside dimensions radially outer back to back of isolating ring.Shaft segment is driven to be such as triangle profile, quadrangular configuration or another polygonal profile in cross section, or Outer cylindrical as stated in the beginning.Inner envelope contour is correspondingly described by triangle, corner or another polygon.Outer envelope profile is corresponding and the triangle, quadrangle or the polygon that expand on the contrary with gap bridge size therewith, or has another geometrical shape.According to above-mentioned explanation, term envelope contour is not only applicable to cylindrical cross section.The norminal size of size corresponding to the driving shaft segment be less than on the base of isolating ring of the inside envelope contour of the isolating ring in transmission shaft segment is arranged on press fit.
If the sheet material of isolating ring is thinner than bridge joint size, the distance between inner envelope contour and outer envelope profile by drip molding as crimping, punching press, radial edges, jacket layer and other carry out cross-over connection by the drip molding of forming without stock removal.Therefore a design proposal of the present invention proposes, and the sheet material of isolating ring has the slotted recess of at least section of one-tenth.Described slotted recess is preferably longitudinal recess on circumference.Described recess, by break-through, punching or bending, makes thus only has comparatively small part (curved section) sheet material to be elastically deformed in it is produced.Limit the bridge joint size of the wall segment cross-over connection of recess between inner envelope contour and outer envelope profile.
Design proposal of the present invention proposes, the radial sheet material limiting slotted recess thickness diametrically with identical adjacent to the sheet metal thickness in portion's section of recess.This isolating ring is by bending method with bending method similarly and thus with the sleeve manufactured compared with small deformation degree.
Relative to previous designs scheme alternatively, the recess on ring is such as manufactured by stretching or roll extrusion process, and described ring has most elasticity extrded material.Therefore design proposal of the present invention proposes, and at least the section of one-tenth ground is thinner than the sheet material of adjacent section on circumference of isolating ring diametrically for the sheet material of the isolating ring of radial restriction slotted recess.Form the radial structure height being four times in sheet metal thickness by the structure of sheet material portion section and size when needed, wherein utilize sheet material portion section, slotted recess by axially, circumference ground, tangentially or radially to limit.
In slotted recess one, two, preferably three or more longitudinal direction spirally or along isolating ring extend.Longitudinal direction is interpreted as the central axis being parallel to isolating ring or driving shaft segment.On the isolating ring of (rotation) symmetric design, longitudinal direction and (rotation) or the axis of symmetry are in the same way (parallel).All slotted recess of isolating ring are in the same way, or adjacent slotted recess alternately on the contrary inwardly envelope contour or towards the outside envelope contour on bottom land side, utilize the sheet material of spacer ring to limit, and to be spaced from each other by sheet material.The slotted recess with the shell-like isolating ring of substantially cylindrical cross section radially-inwardly or the sheet material passing outwardly cover limit.If isolating ring to be arranged in transmission shaft segment and radial direction outwards limits slotted recess, isolating ring and transmission shaft segment surround passage in-between, by described passage, lubricant oil such as can be delivered to the rolling bearing of another free pulley kept at a certain distance by isolating ring from the rolling bearing of free pulley.
In addition the present invention proposes a kind of isolating ring, described isolating ring around at least one transmission shaft segment, and to remain in transmission shaft segment with an axial distance at this at least one transmission component on the circumference of spin axis.Isolating ring at least by one with spin axis in the same way, the portion's section with hollow cylinder shape forms.
Portion's section/hollow cylinder is at least formed by a sheet material bar, its end local inclination interfixing on circumference.
Design like this, makes mutually directed end shape be bonded with each other with the form of riveting parts in locking manner.Riveting parts is that the drip molding thereon with undercutting is bonded with each other the link had accordingly in the drip molding of another undercutting.Such typical link is the link being designed to dove-tail or button shaped on cross section.
This isolating ring can to manufacture with relatively less tool expense with larger piece count.Produce a small amount of waste material aborning.Produce this isolating ring or at least produce there is or not have portion's section of flange time, first preferably sheet material bar is cut from continuous material and carries out form-cutting.The initial length of sheet material bar conforms to the circumference of the hollow cylinder made on deflection curve.In form-cutting, flange, recess and hole or similar structural characteristics are rolled, punching press, die-cut or cut out.Circumference is circular or polygonal.
The light sheet that portion's section can be 0.2 to 1mm by thickness of slab is made, or is greater than 1mm by thickness of slab alternatively and makes to the sheet material being greater than 5mm.If isolating ring temporarily or constantly bears higher thrust load, this isolating ring just designs in the axial direction as far as possible forcefully.In this case, light sheet is easy to bend under a load and heave.Strive in this case using heavy wall isolating ring.
A design proposal of the present invention proposes, and portion's section closed on circumference has at least one radial hole.Therefore there is the volume of the isolating ring of relatively thick wall and portion of material can be reduced based on the weight of volume thus, in order to realize that Kong Ercong isolating ring eliminates this part material.Under the best circumstances, the hole of multiple passage section distribution on circumference is set.In addition, the hole on multiple isolating ring being made up of thin or thick sheet material is lubricant passageway or grease storage.In addition, such hole is the device for distribute lubricant, and it stirs or be distributed in the oiling agent on through surface and in the surrounding environment of the isolating ring rotated rotatably.
In this isolating ring, be at least preferably full of a volume by the material of the sheet material of its forming portion section, its value ratio holds the space body product value little 40% to 60% by the specifically described hollow cylinder of profile.The weight of this isolating ring decreases 60% or 40% relative to the approx weight (100%) of hollow cylinder.In this case preferably based on, at least portion's section fills cylindrical profile diametrically completely.Describe the profile of hollow cylinder in the ideal case with the body rib of spin axis portion's section in the same way, its wall is solid material.The real material volume of portion's section or the size of material weight passing hole and quantity are determined in this case.Size and quantity determine portion of material volume or portion of material weight, and it is removed from hollow cylinder when manufacturing hole, to produce (vacancy volume) portion's section.
If the cross section of the connecting sheet between each hole is formed at least foursquare, especially ensure that the isolating ring rigidity relative to the high capacity up to 80KN.In other words, from hole to edge (end face) or to adjacent hole, preferred at least the same with the radial dimension of connecting sheet with the size (width) of spin axis connecting sheet in the same way.
As stated in the beginning, sheet material bar mutual to curved end shape in locking manner, force closure ground or material be interconnected in locking manner.Force closure between end occurs with shape is as stated in the beginning sealed thereupon, and described force closure is such as produced by the material extruding on the position that shape is sealed, thus shape sealed be that lasting intangibility removes.
Material fit is guaranteed preferably by welding.If soldered with long weld seam with the isolating ring length in the same way in spin axis, weld phase mutual designation and tangent to each other or be oppositely arranged on circumference sheet material bar end time heat input can cause undesirable distortion of isolating ring geometrical shape.The length of isolating ring is longer compared with the radial dimension of wall (wall thickness).If soldered with long weld seam with the isolating ring length in the same way in spin axis, this can cause the control problem of the welding current of end-contact-welding position or the mass defect in weld seam/welding position.Therefore the cross section of welding position will be reduced in an advantageous manner.
Realize this object thus according to the present invention, described portion section is soldered at least two positions independent of each other.Also be provided with, first the end of sheet material bar has two or more outstanding fritter on end face, and its volume approximately conforms to the material volume melted to be connected when welding.End is only connected to each other partly each other on the total length of portion's section after welding.Welding current can be controlled to be less preferably simultaneously, there is less welding flame and the heat be transferred in isolating ring is less.That there is the steel that Kohlenstoffgehalt mass percent is C < /=0.5% as the welding steel for portion's section.
Aforementioned design design proposal of the present invention proposes, and connecting sheet portion section positioned opposite to each other is welded to one another on sheet material bar end.Delivered heat when welding is relatively limited.In addition, the requirement of the very applicable welding technique of material section of connecting sheet, in this case, the plate cutting end of the mutual aligning formed when the sheet material bar of zonal cooling material is so designed, make thereon preferably at least each only stamping-out go out the part in one or more hole.Another part is formed respectively on the end be oppositely arranged.Described hole on side open wide and each other and/or towards end face in a longitudinal direction (with spin axis in the same way) by corresponding to part connecting sheet portion section separate or limit.The end of connecting sheet portion section is the interface of connecting sheet portion section positioned opposite to each other respectively, and is relatively guided and weld each other, finally forms complete connecting sheet.Therefore between the end of soldered sheet material bar, two or more complete hole is surrounded.
For due to cost reason or the isolating ring should in main wall based on the high request of axial load with solid material, according to the optimum welding providing holes on the link position of sheet material bar end.Cost reason is such as due to additional cost in this case, and it is owing to being formed for the cycle of the prolongation in the multiple hole of stamping-out successively replaced for one or two the short period in stamping-out hole.If each in the cutting tip of sheet material bar cuts out respectively the half profile in a hole or multiple hole when utilizing cut-out film to block continuous material simultaneously, the such as this process time for stamping-out is all cancelled.
Correspondingly, the volume by the spatial volume little 1% to 5% of the specifically described hollow cylinder of profile is held by the preferred packing ratio of the material of the sheet material of its forming portion section.
Another design proposal of the present invention proposes, and portion's section has two flat end faces mutually deviated from, and it has the permissible error of maximum 1% of size for portion section wall thickness S each other in norminal size with spin axis distance in the same way.Portion's section wall thickness calculates like this:
Be applicable to polygonal embodiment at this, Da be from bight to bight or from bight to flat wall segment outside ultimate range, Di be from bight to bight or from bight to flat wall segment inside minimum range.Each distance and jante et perpendiculaire.Transmission component and gear can axially by very accurately mutually positioning.
If when the material of separation sleeve is formed from steel and has the tensile strength Rm of minimum 2000Mpa at least from the teeth outwards, can high strength be realized.
