Abstract
The utility model discloses a push-type centering clutch bearing unit belonging to the technical field of rolling bearings and being mainly used for solving the problem that the clutch bearing unit is rapidly out of operation because a clutch bearing is easy to burn because of nonuniform stress and lubricating grease in the bearing loses and dust and impurities enter the bearing in the traditional clutch bearing unit. The push-type centering clutch bearing unit is mainly characterized by comprising a clutch bearing and a clutch shaft sleeve which are elastically connected together through a wave spring, wherein a front end sealing ring is arranged between the front ends of an inner ring and an outer ring of the clutch bearing, the front end sealing ring is elastically and axially compacted on the end surface of the inner ring through the wave spring, and a sealing lip on the front end sealing ring is in contact with the inner side of a rib of the outer ring. The push-type centering clutch bearing unit not only is provided with the bearing with favorable double-end-surface sealing performance, but also ensures that the clutch bearing has better radial centering performance than the clutch shaft sleeve, and is mainly used for an automobile clutch mechanism.

Summary of the invention
The purpose of the utility model is exactly to above-mentioned deficiency a kind of good double seals performance bearing that both had to be provided, and makes the relative clutch bushing of clutch bearing have the good radially clutch shaft bearing unit of aligning performance again.
The technical solution of the utility model is: a kind of pushing-type aligning clutch shaft bearing unit; Comprise clutch bearing and clutch bushing; The contact seal structure of band back-end sealing circle is arranged between the inside and outside circle of clutch bearing rear end, and it is characterized in that: described clutch bearing and clutch bushing link together through waveform spring elasticity; Between the inside and outside circle front end of clutch bearing, be provided with the forward end seal circle, this forward end seal circle through waveform spring elastic axis to being pressed on the inner ring end face, and side contacts in sealing lip on the forward end seal circle and the outer ring rib.
Clutch bearing described in the technical solution of the utility model is an angular contact ball bearing.
The endoporus of the clutch bushing described in the technical solution of the utility model can slide on axle, and outer wall is provided with the step-like axle sleeve groove that a side end face can be adjacent to clutch bearing inner ring respective side end face, opposite side can install and fix waveform spring groove.
The elastic ring of waveform spring described in the technical solution of the utility model for axially having fluctuating, a middle place to block along circumference.
Back-end sealing circle described in the technical solution of the utility model and forward end seal circle are the rubber seal of band skeleton.
The utlity model has following good effect:
1) clutch bearing and clutch bushing link together through waveform spring elasticity; Between clutch bearing internal diameter and the clutch bushing radial clearance is arranged; The relative clutch bushing of clutch bearing can move radially, clutch bearing possesses the self-regulated heart function; But self-adapting adjusted positions when combining with the clutch disk diaphragm guarantees optimum contacting state, make the clutch shaft strength evenly, prolong clutch bearing working life;
2) end adopts conventional contact seal circle sealing between the inside and outside circle of clutch bearing; The other end is through cooperating installation, leaning on the seal ring of waveform spring elastic axis side contacts on being pressed on the inner ring end face, in sealing lip and the outer ring rib with clutch inner ring internal diameter; Also realize contact seal from the bottom at this end, reach the effect of clutch bearing double seals.The waveform spring had both played the effect that clutch bearing and clutch bushing elasticity are coupled together, and played the effect that the bottom front portion seal ring is compressed, guarantees sealing effect again;
3) the utility model uses the waveform spring to connect clutch bearing and clutch bushing, has that design of part is simple, cost is low, advantage easy for installation, reliable.
The utility model had both had good double seals performance bearing, made the relative clutch bushing of clutch bearing have the good radially characteristics of aligning performance again.The utility model is mainly used in automobile clutch mechanism.
Description of drawings
Fig. 1 is the existing common structural representation of clutch shaft bearing unit.
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
As shown in Figure 2.A kind of pushing-type aligning of the utility model clutch bearing unit comprises clutch bearing 11, clutch bushing 12, waveform spring 18, back-end sealing circle 16, forward end seal circle 17.
Clutch bearing 11 is to bear thrust load, this end inboard at bearing outer ring side end face (front side) 13 places rib inboard 22 seals in the outer ring from the bottom through cooperate the forward end seal circle of installing 17 with inner ring internal diameter and end face; The other end installed inside has the angular contact ball bearing of back-end sealing circle 16, has the effect that two ends seal fully.
Clutch bushing 12 be its endoporus can slip on axle, step end face is adjacent at end face 19 places with the clutch bearing inner ring and cooperates the step-like sleeve that is used to bear thrust load, there is the groove 21 that installs and fixes waveform spring 18 its front portion.
The elastic ring of waveform spring 18 for axially having fluctuating, a middle place to block along circumference.Waveform spring 18 is installed in groove 21 places on the clutch bushing 12, has both played the effect that clutch bearing 11 and clutch bushing 12 elasticity are coupled together, and plays the effect that bottom front seal ring 17 is compressed, guarantees sealing effect again.
Two seal rings described in the utility model technical solution are the rubber back-end sealing circle 16 and forward end seal circle 17 of band skeleton; Wherein forward end seal circle 17 is installed on the bearing inner race; Seal from the bottom to bearing one end outer ring rib inboard 22; The other end back-end sealing circle 16 is conventional sealing, and two seal rings reach together bearing is carried out the complete seal action of Double End.
Installation process:
Forward end seal circle 17 is installed to bearing inner race internal diameter 20 places, and back-end sealing circle 16 is installed in the bearing outer ring groove, accomplishes the bearing assembling; Then with bearing and axle sleeve in end face 19 central lines placement of aliging along the place; 18 embeddings of waveform spring are installed to axle sleeve groove 21 places; Clutch bearing 11, the clutch bushing 12 axial elasticity power through waveform spring 18 compresses each other at end face 19 places and links together, and promptly accomplishes the assembling of clutch shaft bearing unit.
Bear the end thrust load of clutch disk at 13 places, bearing outer ring side end face and pass to axle sleeve at end face 19 places; Because the elasticity of waveform spring 18; Clutch bearing 11 relative clutch bushings 12 can move radially, bearing possesses the self-regulated heart function; But self adaption is radially adjusted the position at end face 19 places, guarantees optimum contacting state, make shaft strength evenly, prolong bearing working life; The bearing rear end is provided with back-end sealing circle 16; Front end installs, leans on waveform spring 18 elastic axiss to the forward end seal circle 17 that is pressed on the inner ring end face, sealing lip contacts with inboard 22 places of outer ring rib through cooperating with inner ring internal diameter 20 places; Also realize contact seal from the bottom at this end, reach the effect of bearing double seals; Waveform spring 18 had both played the effect that clutch bearing 11 and clutch bushing 12 elasticity are coupled together, and played the effect that bottom front seal ring 17 is compressed, guarantees sealing effect again.
