三点接触球轴承设计改进浅析

Improvement on design of three-point contact ball bearing

三点接触球轴承结构复杂、设计难度大,为满足航空发动机的配套和延寿需要,对其设计技术进行了改进,并应用在新型航空发动机主轴轴承的设计中,取得了良好效果。

Three-point contact ball bearings are not only complicated in structure but also difficult in design. In order to provide necessary accessories for aero-engine and extend its service life, the design technology of the bearings was improved, meanwhile used in the development of a new type of aero-engine spindle bearing. Good reults were eventually achieved.
