Abstract
The utility model provides a thrust kingpin combination bearing for spindle. The taper bearing belongs to the technical field of a rolling bearing. It mainly be solve current for the knuckle thrust bearing exist assembly precision adverse effect and filth entering bearing and influence life's problem. Its leading features is: including dustcoat, outer lane, blowout patche, rolling element, blowout patche O shape sealing washer, kingpin, holder and inner ring spacer, the big terminal surface chamfer department of blowout patche takes a step, the dustcoat has than the big terminal surface of blowout patche narrow bottom surface, and the bottom surface of dustcoat and the step laminating of blowout patche chamfer department, the terminal surface of dustcoat is less than the terminal surface of blowout patche, rolling element and holder set up between blowout patche and outer lane, be equipped with the sealing washer subassembly at outer ring end face. The utility model has the characteristics of make combination bearing under the prerequisite that does not reduce outer lane sealing performance, eliminate dustcoat, the adverse effect of seat circle to assembling the precision, improve sealing performance to reduce bearing weight, can be used to serial spindle combination bearing.
Description
Technical field
The utility model belongs to technical field of rolling bearings, and in particular to new structure bearing is saved in a kind of motor turning,
For the kingpin support of spindle.
Background technology
Knuckle is the hinge of wheel steering, and its pattern is mainly fork-shaped.To make steering flexibly, under knuckle ear with it is front
Thrust bearing, or damping bearing, or sliding bearing, or drawn cup needle roller bearing are housed between axle 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 are constituted, generally by seat ring 01, blowout patche 02, roller 04, retainer 07, needle roller 14, the sealing of blowout patche O shapes
Circle 48, outer ring spacer 53, cone spacer 63, outer cover 93, outer ring 94 etc. are constituted, as shown in Figure 1.Because outer cover 93 is by the outer end of blowout patche 02
Bread is sealed, and is not provided with narrow bottom structure, thus outer cover 93, seat ring 02 have adverse effect to assembly precision.Due to the end face of outer ring 94
Sealing structure is not provided with, thus there is a problem of that dirt enters bearing and affects bearing service life.
The content of the invention
The purpose of this utility model is just to provide one kind on the basis of knuckle flexibility of revolution is not reduced, and eliminates outer cover
Needle roller thrust combination bearing is saved in adverse effect to assembly precision, the motor turning for improving sealing property.
To reach above-mentioned purpose, the technical solution of the utility model is：Needle roller thrust built-up shaft is saved in a kind of motor turning
Hold, including outer cover, outer ring, blowout patche, rolling element, blowout patche O-ring seals, needle roller, retainer and cone spacer, the internal diameter tape spool of blowout patche
Circle O-ring seals, it is characterised in that：One step of band at the large end face chamfering of the blowout patche；The outer cover carries end bigger than blowout patche
The narrow bottom surface in face, and the bottom surface of outer cover fits with step at blowout patche chamfering；End face of the end face of the outer cover less than blowout patche；It is described
Rolling element and retainer are arranged between blowout patche and outer ring；Seal ring assembly is provided with cycle surface.
Outer ring, blowout patche described in technical solution of the present utility model is with the relationship type with rolling mates
The steel ring of formula raceway, raceway groove.
Rolling element described in technical solution of the present utility model is cylindrical roller thrust, thrust cone roller, steel
Ball or metal slide ring.
Seal ring assembly described in technical solution of the present utility model is the single lip sealing ring with steel plate frame.
Retainer described in technical solution of the present utility model is engineering plastics cage.
The external diameter of the outer cover described in technical solution of the present utility model is in 30 ~ 100mm.
The utility model has the positive effect that：
1st, one step of band at blowout patche large end face outer diameter chamfering, the step is engaged with the narrow bottom of outer cover and eliminates drawn cup pair
The adverse effect of assembly precision, it is ensured that bearing face run-out tolerance is fallen below in 0.02mm by original 0.10mm or so, so true
Protect bearing and installed and used precision, improve 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 holds, is also greatly reduced the weight of combination bearing, meets the trend that automobile develops towards lightweight.
3rd, the two ends of bearing are designed with sealing structure, it is to avoid dirt enters bearing, can improve the service life of bearing.
The utility model has makes combination bearing on the premise of outer ring sealing property is not reduced, and eliminates outer cover, seat ring pair
The adverse effect of assembly precision, improves sealing property, and the characteristics of reduce bearing weight.The utility model can be used for series automobiles
Knuckle combination bearing.
Description of the drawings
Fig. 1 is the structural representation of the existing class bearing.
Fig. 2 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings explanation is further explained to the utility model.
As shown in Figure 2.A kind of motor turning of the utility model saves needle roller thrust combination bearing including blowout patche 03, rolling element
05th, 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,
The internal diameter band blowout patche O-ring seals 48 of blowout patche 03, blowout patche O-ring seals 48 are ring-shaped rubber sealing ring, and retainer 07 is engineering
Plastic cage.One step of band, is easy to the edge of outer cover 95 to be fitted on the step at the large end face chamfering of blowout patche 03, eliminates
Adverse effect of the outer cover 95 to assembly precision.Outer cover 95 carries the bottom surface narrower than the large end face of blowout patche 03, and the end face of outer cover 95 is less than
The end face of blowout patche 03, and the bottom surface of outer cover 95 fits with step at the chamfering of blowout patche 03.Rolling element 05 and retainer 07 are arranged at axle
Between circle 03 and outer ring 96, the seat ring of thrust bearing is canceled, on the premise of flexibility of revolution is not reduced, greatly reduce group
The quality that sympodium holds.In outer ring 96, end face is provided with seal ring assembly 68, and seal ring assembly 68 is the single lip seal with steel plate frame
