Background technique
Single direction thrust ball bearing generally comprises a blowout patche, seat ring and steel ball, retainer assembly, and wherein, blowout patche, seat ring, steel ball-holder assembly can be installed separately.This class bearing, can bear unidirectional axial load, and can make unidirectional axially locating, but must not bear any radial load.
At present, the design of thrust ball bearing is open architecture, and without any sealing configuration or dustproof construction, open type design bearing is because of its function that does not possess any the isolation external world with bearing working district, and bearing is subject to the impact of operating mode larger working life.As mounting sealing device outside bearing, require installing space large, during the high and installation fee of cost.
Model utility content
The defect existing for prior art, the purpose of this utility model is to provide a kind of simple in structure, good thrust ball bearing of sealability.
The technological scheme that realizes the utility model object is:
A kind of thrust ball bearing, comprise seat ring, blowout patche, rolling element, case and seal ring, between described seat ring and blowout patche, form an annular space, in this annular space, be provided with a raceway, rolling element is arranged in raceway, and described case is arranged on the outside of foundation ring and blowout patche; The bottom of case contacts with the lower surface of foundation ring, seal ring is arranged between blowout patche and case, described seal ring comprises skeleton and O-ring seal, O-ring seal is fastened on the external diameter of annular skeleton, the internal diameter of skeleton is fixed on blowout patche external diameter, described O-ring seal is provided with lip, lip and encloser inner wall interference fit.
Above-mentioned skeleton cross section is L shaped, and the external diameter of skeleton is wrapped up by O-ring seal, and described O-ring seal is oblique lips structure, and two lips are inclined upwardly all and encloser inner wall interference fit.
Described rolling element is spherical rolling body.
Described case is straight cylinder type, and its bottom surface is provided with through hole, and the diameter of this through hole is more than or equal to the inner diameter of foundation ring, is less than the outer diameter of foundation ring.
Described seat ring, blowout patche, rolling element all adopt GCr15 steel to make, and the skeleton on case and seal ring adopts No. 10 steel plates to make, and O-ring seal adopts nitrile butadiene rubber to make.
The utlity model has positive effect: of the present utility model simple in structure, easy to assembly, be provided with seal ring and case, the outer radial of O-ring seal tilts and the tight butt of case internal diameter.Adopt this structure effectively to solve the problem that bearing working district is isolated from the outside, improved the applying working condition of bearing, practicability is good, and has leakproof fat and dust reduction capability, has promoted the working life of bearing.
Accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
