Description
Technical field
This utility model relates to technical field of bearings, particularly to a kind of wear resistant ball bearing.
Background technology
Bearing be widely used in machine-building, Aero-Space, transportation, the energy, electric power, mining, metallurgy, building, chemical industry,
Nearly all industry that the national defence such as IT, household electrical appliances is civilian.Rolling bearing is a kind of by the sliding friction between axle and the axle bed of operating
Become rolling friction, thus reduce the mechanical organ of a kind of precision of friction loss, the rolling bearing one when high speed rotating
As use precision bearing.Rolling bearing is during running up, and rolling element centrifugal force to be produced, centrifugal action is in bearing
Lasso, it is together with plus load, and lasso is produced contact stress, and contact stress is the main cause that bearing fatigue destroys.Special
It not the CONTACT WITH FRICTION of rolling element and inner and outer ring surface, the most in use occur that fretting fatigue is damaged, reduce whole
The service life of body.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency, it is provided that a kind of wear resistant ball bearing, have mar proof high,
Good corrosion resistance, the feature of length in service life.
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of wear resistant ball bearing, including outer ring, inner ring, rolling element and retainer, medial wall, described outer ring is interior with described
Circle lateral wall is respectively provided with the rolling groove inlaying rolling element, is provided with some installing holes, described installing hole in described retainer
Number is identical with described rolling element number, and described outer ring and described inner ring all use GGr15 bearing steel to make, described outer ring and institute
Stating inner peripheral surface and be provided with a wearing layer, described wearing layer gauge is 0.25mm～0.55mm, and described wearing layer is that carbon nitrogen is total to
Infiltration layer, described rolling element uses Si3N4 ceramic material to make, and described retainer is made up of polytetrafluoroethylmaterial material.
Described wearing layer preferred thickness a size of 0.35mm～0.45mm.

As it is shown in figure 1, this utility model provide a kind of wear resistant ball bearing, including outer ring 1, inner ring 4, rolling element 3 and
Retainer 2, medial wall, outer ring 1 and inner ring 4 lateral wall are respectively provided with the rolling groove 6 inlaying rolling element 3, set in retainer 2
Having some installing holes 7, installing hole 7 number is identical with rolling element 3 number, conveniently completes bearing and installs, and outer ring 1 is all adopted with inner ring 4
Making with GGr15 bearing steel, outer ring 1 and inner ring 4 surface are provided with a wearing layer 5, wearing layer 5 gauge be 0.25mm～
0.55mm, wearing layer 5 is carbonitrided case, is designed by optimization so that it is have good wearability and corrosion resistance, the most excellent
Changing gauge scope, reduce fragility so that it is have good intensity and toughness, increase service life, rolling element 3 uses
Si3N4 ceramic material is made, and can improve the anti-wear performance of rolling element 3, decay resistance, sliding capability and heat-resisting quantity, special
Not being applicable to adverse circumstances use, retainer 2 is made up of polytetrafluoroethylmaterial material, has high temperature resistant, the feature that coefficient of friction is low,
Avoid rolling element 3 that wear phenomenon occurs, improve the serviceability of entirety.
Further, this utility model wearing layer 5 preferred thickness a size of 0.35mm～0.45mm.
Further, this utility model wearing layer 5 preferred thickness a size of 0.40mm.
Further, this utility model outer ring 1 and inner ring 4 case hardness are 63.5HRC～64.5HRC.
This utility model improves by optimizing design, and outer ring 1 and inner ring 4 surface use the wearing layer 5 of carbonitrided case, knot
Close the rolling element 3 of Si3N4 ceramic material, improve the wearability of entirety, corrosion resistance, go for making under adverse circumstances
With, there is mar proof height, good corrosion resistance, the feature of length in service life.
As known by the technical knowledge, this utility model can be by other essence without departing from its spirit or the reality of essential feature
The scheme of executing realizes.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only
's.All in the range of this utility model or be equal to the change in the range of this utility model all by this utility model bag
Contain.
