Description
Technical field
The utility model belongs to technical field of rolling bearings.Be specifically related to serial high sealing performance highi degree of accuracy steering axle of automobile new structure thrust-bearing, turn to supporting for automobile front axle.
Background technique
At present, turn to the bearing of supporting for automobile front axle, have thrust ball bearing, thrust roller bearing, damping bearing.Bearing is arranged on steering axle stub, slowly runs with front-wheel steer.Use the thrust-bearing on steering axle to have band sealing, also have the sealing of not being with, to use the bearing of band sealing be development trend.
Because motor turning bearing is to be contained on stub outside exposedly, be not easy to cause dust and water to enter in bearing with the product of sealing, cause the early failue of bearing.The product of existing band sealing causes sealability because sealing configuration is single be not very desirable, can cause the early failue of bearing yet.
Steering bearing generally has outer cover 93, and blowout patche 02, seat ring 01, rolling element 04 are contained in outer cover, as shown in Figure 1.Under normal circumstances, at the bottom of cover band, cover the whole end face of blowout patche, because cover is stamping part, machining accuracy is lower, bottom surface injustice, larger to bearing height deviation effects while laminating with blowout patche end face, and cause bearing face run-out tolerance larger, and then affect installation precision and the usability of thrust-bearing, the working life that can greatly reduce bearing when serious.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of thrust-bearing that makes both to have good sealing usability for above-mentioned deficiency, has again the good serial high sealing performance highi degree of accuracy steering axle of automobile thrust-bearing of installing and using precision.
Technical solution of the present utility model is: a kind of serial high sealing performance highi degree of accuracy steering axle of automobile thrust-bearing, comprises outer cover, blowout patche, seat ring and slip ring and the collar or rolling element and retainer; It is characterized in that: the both ends of the surface of described outer cover are fitted with blowout patche slope, seat ring slope respectively, and outer cover two ends are all respectively lower than blowout patche, seat ring exterior edge face; Non-skeleton rubber sealing is housed, the internal diameter band race shape seal ring of seat ring on the external diameter circumferential groove of described seat ring; Between described blowout patche and seat ring, be provided with seal ring.
The internal diameter tape spool ring RunddichtringO of blowout patche described in technical solution of the present utility model.
Thrust-bearing external diameter described in technical solution of the present utility model is at 30 ~ 100mm.
The ring-like seal ring of blowout patche described in technical solution of the present utility model is the O-ring seal of O type or special-shaped O-ring seal.
Race RunddichtringO described in technical solution of the present utility model is ring-shaped rubber seal ring.
Seal ring between blowout patche described in technical solution of the present utility model and seat ring is the tubular rubber seal with steel plate frame.
Rolling element described in technical solution of the present utility model can be cylindrical roller thrust, thrust cone roller, guiding principle ball.
Seat ring described in technical solution of the present utility model, blowout patche can be with the relevant pattern raceway matching to rolling element, the steel ring of raceway groove.
Slip ring described in technical solution of the present utility model and the collar are metal slip ring and the engineering plastics collar.
The utlity model has following good effect:
1, non-skeleton rubber seal ring on seat ring, has not only ensured the sealing usability that bearing is good but also ensure the fabrication technology performance that it is good; The effect that can play dust-proof leak-proof between axle, seat ring with tubular rubber seal, dust does not enter, and grease can not leak; Between axle, seat ring, can play the effect of dust-proof leak-proof with tubular rubber seal; When blowout patche and stub interference fit, blowout patche internal diameter can not play the effect of dust-proof leak-proof yet with sealing.This sealing configuration has significantly improved the sealability of bearing, can allow roller normally work for a long time in the space of sealing, thereby improve bearing life.
2, outer cover two ends roll extrusion assembling on the corresponding slope on axle, seat ring with slope pattern, eliminated the bearing height deviation that causes because of shroud floor injustice in the situation at the bottom of outer cover one sideband and the variation of end face run-out tolerance, bearing face run-out tolerance is dropped in 0.02mm above by original 0.05mm.The variation of this structure can improve bearing and install and use precision, improves bearing working life and reliability.
The utlity model has and make thrust-bearing both there is good sealing usability, there is again the good feature of installing and using precision.The utility model is mainly used in serial high sealing performance highi degree of accuracy steering axle of automobile thrust-bearing.
Brief description of the drawings
Fig. 1 is the common structural representation of this class bearing.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further explained to explanation.
As shown in Figure 2.The utility model series high sealing performance highi degree of accuracy steering axle of automobile comprises outer cover 96, blowout patche 09, seat ring 08, rolling element 04 and retainer with thrust-bearing, and thrust-bearing external diameter is at Φ D30 ~ 100mm, and retainer can be stamping steel plate retainer, nylon cages.In the time of full roller, full ball or damping bearing structure, also shouldn't retainer.Wherein, outer cover 96 is not with bottom surface, the both ends of the surface of outer cover 96 are fitted with blowout patche 09 slope, seat ring 08 slope respectively, and outer cover 96 two ends are all respectively lower than blowout patche 09, seat ring 08 exterior edge face, outer cover 96 is the cylindrical structures on band slope, two ends as shown in Figure 2, instead of cup type structure as shown in Figure 1.The internal diameter of blowout patche 09 can tape spool ring RunddichtringO 48, also tape spool ring RunddichtringO not.The ring-like seal ring 48 of blowout patche is the O-ring seal of O type or special-shaped O-ring seal, and special-shaped O-ring seal is other O type modification pattern seal rings.Non-skeleton rubber sealing is housed on the external diameter circumferential groove of seat ring 08, the internal diameter band race shape seal ring 48 of seat ring 08, race RunddichtringO 48 is ring-shaped rubber seal ring.Between blowout patche 09 and seat ring 08, be with seal ring, seal ring is the tubular rubber seal 68 with steel plate frame 99.Rolling element can be cylindrical roller thrust, thrust cone roller, steel ball or metal slip ring.Seat ring 08, blowout patche 09 are with the relevant pattern raceway matching to rolling element 04, the steel ring of raceway groove.Between seat ring, blowout patche, can be also metal slip ring and the engineering plastics collar (damping bearing).
Consider bearing structure and assembling applicable cases, the utility model adopts three kinds of seal form to hinder the leakage that enters and prevent grease of dust muddy water., adopt structures end of with not of outer cover 96 end faces, thereby eliminated the adverse effect of outer cover to assembly precision with end outer cover 93 and the impact that the assembly relation of blowout patche 02, seat ring 01 produces bearing performance for original.This airframe bearing uses in batches on STR bridge.
