摘要
大通道四支点接触球推力轴承是涡轮引鞋最重要的组成部分,对其进行承载能力分析有利于提高其使用寿命。文中结合静力接触力学理论及有限元仿真软件进行分析,对三组不同接触角情况下的四支点接触球轴承进行了研究,得出接触角与承载能力的关系,发现通过调整接触角可以提高轴承的承载能力。为涡轮引鞋用四支点接触球推力轴承的优化与设计提供一定的参考。
The four-fulcrum contact ball bearing is the most important part of turbine guide shoe, carrying capacity analysis is helpful to improve its service life. This paper uses contact mechanics theory and finite element simulation software to study three groups of four-fulcrum contact ball bearings with different contact angles. It is found that the bearing capacity can be improved by adjusting the contact angle. It provides reference for design and optimization of fourfulcrum contact ball bearing that used in turbine guide shoe.
