Abstract
The utility model relates to a kind of thrust angular contact ceramic ball bearing, comprise outer ring, inner ring and ceramic ball, described outer ring is provided with the R type raceway with fore shaft, and described inner ring is provided with R type raceway, and described ceramic ball is located between the R type raceway of outer ring and the R type raceway of inner ring.Compared with prior art, the utility model has the advantages such as bearing capacity is strong, performance better, Applicable scope is wider.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of thrust angular contact ceramic ball bearing.
Background technique
At present, the bearing on the large-scale rotating disk of oil drilling and extracting equipment, uses in the rugged environment of higher rotation speed, high loading, high temperature.Conventional has self-aligning thrust roller bearing and common angular contact thrust ball bearing, and self-aligning thrust roller bearing has high bearing capacity, but is subject to the impact of frictional heat, is not suitable for High Rotation Speed; Common angular contact thrust ball bearing is by having higher rotation speed, but bearing capacity is limited.In addition, the requirement of these two kinds of bearings to lubrication is high, once insufficient lubrication, bearing can lose efficacy at once.
Model utility content
The purpose of this utility model be exactly provide that a kind of bearing capacity is strong to overcome defect that above-mentioned prior art exists, performance is better, Applicable scope is wider thrust angular contact ceramic ball bearing.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of thrust angular contact ceramic ball bearing, it is characterized in that, comprise outer ring, inner ring and ceramic ball, described outer ring is provided with the R type raceway with fore shaft, described inner ring is provided with R type raceway, and described ceramic ball is located between the R type raceway of outer ring and the R type raceway of inner ring.
This bearing is full spherical structure, is uniformly distributed ceramic ball between the R type raceway of the R type raceway in outer ring and inner ring.
Described outer ring and inner ring are the lasso through the manufacture of case-carbonizing process GCr15 material.
Described ceramic ball is the ball of Si3N4 material manufacture.
Lubricant oil is provided with between described ceramic ball.
Compared with prior art, the utility model has the following advantages:
1, bearing capacity is strong, guides, saving a part of free space in Internal and external cycle raceway, for filling more ceramic ball, improve the bearing capacity of bearing without retainer;
2, ceramic ball thermal expansion coefficient is little, bearing ball will be caused to expand because of the reason of temperature in high temperature environments, substantially increase the serviceability temperature of whole bearing like this;
3, ceramic ball bearing friction factor is little, compared with plain bearing steel matter, adapts to higher speed demand;
4, ceramic ball has self-lubricating function, still can normally run during short-term oil starvation;
5, Internal and external cycle is through case-carbonizing process, improves the hardness of raceway face, wear resistance and fatigue strength, under equal operating mode, extends the working life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of without retainer thrust angular contact ceramic ball bearing, comprise outer ring 01, ceramic ball 02, inner ring 03, ceramic ball is uniformly distributed between outer ring 01 and inner ring 03 raceway.
Described bearing adopts full ball design method, saving a part of free space in Internal and external cycle raceway, for filling more ceramic ball, improve the bearing capacity of bearing.
Ceramic ball 02 thermal expansion coefficient and friction factor little, there is high temperature resistant and high-revolving feature.Ceramic ball 02 has self-lubricating property, and short-term oil starvation still can normally run.Outer ring 01 and inner ring 03, through case-carbonizing process, improve the hardness of raceway face, wear resistance and fatigue strength, under equal operating mode, extend the working life of bearing.
Claims (5)
1. a thrust angular contact ceramic ball bearing, it is characterized in that, comprise outer ring, inner ring and ceramic ball, described outer ring is provided with the R type raceway with fore shaft, described inner ring is provided with R type raceway, and described ceramic ball is located between the R type raceway of outer ring and the R type raceway of inner ring.
2. a kind of thrust angular contact ceramic ball bearing according to claim 1, is characterized in that, this bearing is full spherical structure, is uniformly distributed ceramic ball between the R type raceway of the R type raceway in outer ring and inner ring.
