Abstract
Needle roller thrust combination bearing is saved in a kind of entitled motor turning of the present invention.Belong to technical field of rolling bearings.It mainly solves the problems, such as that existing knuckle thrust bearing exists and enters bearing to assembly precision adverse effect and dirt and influence service life.It is mainly characterized by：Including outer cover, outer ring, blowout patche, rolling element, blowout patche O-ring seals, needle roller, retainer and cone spacer；One step of band at the big end surface chamfer of blowout patche；Outer cover carries the bottom surface narrower than blowout patche large end face, and the bottom surface of outer cover is bonded with step at blowout patche chamfering；The end face of outer cover is less than the end face of blowout patche；Rolling element and retainer are arranged between blowout patche and outer ring；Seal ring assembly is equipped with cycle surface.The present invention has the characteristics of making combination bearing on the premise of outer ring sealing performance is not reduced, eliminating outer cover, seat ring to the adverse effect of assembly precision, raising sealing performance, and reduce bearing weight, available for series automobiles knuckle combination bearing.
Description
Technical field
The invention belongs to technical field of rolling bearings, and in particular to new structure bearing is saved in a kind of motor turning, is used for
The kingpin support of spindle.
Background technology
Knuckle is the hinge of wheel steering, its pattern is mainly fork-shaped.To make steering flexible, ear is with before under knuckle
Thrust bearing, or damping bearing, or sliding bearing, or drawn cup needle roller bearing are housed between axis fist shape part.Bearing is installed
On king pin, the low speed oscillations with front-wheel steer.
With the improvement of punching stretch technique, develop out a kind of motor turning and save combination bearing, the class bearing is by needle roller
Bearing and thrust roller bearing composition, are usually sealed by seat ring 01, blowout patche 02, roller 04, retainer 07, needle roller 14, blowout patche O shapes
Circle 48, outer ring spacer 53, cone spacer 63, outer cover 93, outer ring 94 etc. are formed, as shown in Figure 1.Since outer cover 93 is by the outer end of blowout patche 02
Bread seals, and is not provided with narrow bottom structure, thus outer cover 93, seat ring 02 have adverse effect to assembly precision.Due to 94 end face of outer ring
The problem of being not provided with sealing structure, thus entering bearing there are dirt and influence bearing service life.
The content of the invention
It is an object of the invention to provide one kind on the basis of knuckle flexibility of revolution is not reduced, outer cover is eliminated to dress
Needle roller thrust combination bearing is saved in adverse effect with precision, the motor turning for improving sealing performance.
To reach above-mentioned purpose, the technical scheme is that：Needle roller thrust combination bearing is saved in a kind of motor turning, bag
Include outer cover, outer ring, blowout patche, rolling element, blowout patche O-ring seals, needle roller, retainer and cone spacer, the internal diameter band blowout patche O shapes of blowout patche
Sealing ring, it is characterised in that：One step of band at the big end surface chamfer of the blowout patche；The outer cover is with narrower than blowout patche large end face
Bottom surface, and the bottom surface of outer cover is bonded with step at blowout patche chamfering；The end face of the outer cover is less than the end face of blowout patche；The rolling element
And retainer is arranged between blowout patche and outer ring；Seal ring assembly is equipped with cycle surface.
Outer ring, blowout patche described in the technical solution of the present invention are with related pattern rolling matched to rolling element
The steel ring in road, raceway groove.
The present invention technical solution described in rolling element for cylindrical roller thrust, thrust cone roller, steel ball or
Metal slide ring.
Seal ring assembly described in the technical solution of the present invention is single lip sealing ring with steel plate frame.
Retainer described in the technical solution of the present invention is engineering plastics cage.
The outside diameter of outer cover described in the technical solution of the present invention is in 30 ~ 100mm.
The present invention has the positive effect that：
1st, one step of band at blowout patche large end face outer diameter chamfering, which is engaged with the narrow bottom of outer cover eliminates drawn cup to assembling
The adverse effect of precision, ensure that bearing face run-out tolerance is fallen below in 0.02mm by original 0.10mm or so, which ensures that
Bearing installs and uses precision, improves bearing life.
2nd, remove the seat ring of thrust bearing, cylindrical roller thrust is directly rolled on drawn cup, not only reduce group
The assembly difficulty that sympodium is held, is also greatly reduced the weight of combination bearing, meets the trend that automobile develops towards lightweight.
3rd, the both ends of bearing are designed with sealing structure, avoid dirt from entering bearing, can improve the service life of bearing.
The present invention eliminates outer cover, seat ring to assembling with combination bearing is made on the premise of outer ring sealing performance is not reduced
The adverse effect of precision, improves sealing performance, and the characteristics of reduce bearing weight.The present invention can be used for series automobiles knuckle group
Sympodium is held.
Brief description of the drawings
Fig. 1 is the structure diagram of the existing class bearing.
Fig. 2 is the structure diagram of the present invention.
Embodiment
Explanation is further explained to the present invention below in conjunction with the accompanying drawings.
As shown in Figure 2.A kind of motor turning of the present invention save needle roller thrust combination bearing include blowout patche 03, rolling element 05,
Retainer 07, needle roller 14, blowout patche O-ring seals 48, cone spacer 63, seal ring assembly 68, outer cover 95 and outer ring 96.Wherein, axis
The internal diameter band blowout patche O-ring seals 48 of circle 03, blowout patche O-ring seals 48 are ring-shaped rubber sealing ring, and retainer 07 is engineering plastic
Expect retainer.One step of band at the big end surface chamfer of blowout patche 03, is fitted on the step easy to the edge of outer cover 95, eliminates outer
Cover the adverse effect of 95 pairs of assembly precisions.Outer cover 95 carries the bottom surface narrower than 03 large end face of blowout patche, and the end face of outer cover 95 is less than axis
The end face of circle 03, and the bottom surface of outer cover 95 is bonded with step at 03 chamfering of blowout patche.Rolling element 05 and retainer 07 are arranged at blowout patche
Between 03 and outer ring 96, the seat ring of thrust bearing is canceled, on the premise of flexibility of revolution is not reduced, greatly reduces combination
The quality of bearing.Seal ring assembly 68 is equipped with 96 end face of outer ring, seal ring assembly 68 is single lip sealing ring with steel plate frame,
It can replace outer ring spacer 53 and seal.Rolling element 05 can be cylindrical roller thrust, thrust cone roller, steel ball or metal
Slip ring.Outer ring 95, blowout patche 03 are the steel ring with related pattern raceway matched to rolling element 05, raceway groove.Outer cover
95 outside diameter Φ D are in 30 ~ 100mm.
