Problems solved by technology

Thrust self-aligning roller bearings and ordinary thrust angular contact ball bearings are commonly used. Thrust self-aligning roller bearings have high load capacity, but are not suitable for high-speed rotation due to the influence of friction and heat generation; ordinary thrust angular contact ball bearings are affected by Can have a high speed, but the carrying capacity is limited
In addition, these two types of bearings have extremely high requirements for lubrication. Once the lubrication is not good, the bearings will fail immediately.

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] like figure 1 As shown, a cageless thrust angular contact ceramic ball bearing includes an outer ring 01, ceramic balls 02, and an inner ring 03, and the ceramic balls are evenly distributed between the raceways of the outer ring 01 and the inner ring 03.

[0017] The bearing adopts a full-ball design method, which saves a part of free space in the raceway of the inner and outer rings, which is used to fill more ceramic balls, and improves the bearing capacity of the bearing.

[0018] Ceramic ball 02 has small thermal expansion coefficient and friction coefficient, and has the characteristics of high temperature resistance and high speed. The ceramic ball 02 has self-lubricating properties, and it can still operate normally in a short-term oil shortage. The outer ring 01 and the inner ring 03 are carburized on the surface, which impr...

Abstract

The invention relates to an angular contact thrust ceramic-ball bearing. The bearing includes an outer ring, an inner ring and ceramic balls. The outer ring is provided with an R type roller path having a locking hole. The inner ring is provided with an R type roller path. The ceramic balls are disposed between the R type roller path of the outer ring and the R type roller path of the inner ring.Compared with the prior art, the bearing has advantages of high bearing capacity, better performance, a wider application range, and the like.

Description

technical field [0001] The invention relates to a bearing, in particular to a thrust angular contact ceramic ball bearing. Background technique [0002] At present, the bearings used on large turntables of oil drilling and production equipment are used in harsh environments with high speed, high load and high temperature. Thrust self-aligning roller bearings and ordinary thrust angular contact ball bearings are commonly used. Thrust self-aligning roller bearings have high load capacity, but are not suitable for high-speed rotation due to the influence of friction and heat generation; ordinary thrust angular contact ball bearings are affected by Can have a high speed, but the carrying capacity is limited. In addition, these two types of bearings have extremely high requirements on lubrication. Once the lubrication is not good, the bearings will fail immediately. Contents of the invention [0003] The purpose of the present invention is to provide a thrust angular contact ...
