水轮发电机托瓦支撑推力轴承的润滑计算

The Lubrication Calculation of Thrust Bearing With Pivoted Supports for Hydrogenerator

本文对具有水冷和双层结构的刚性单点球面支撑推力轴承及托瓦支撑推力轴承分别进行了三维热弹流动力润滑计算，分析比较了托瓦式支撑推力轴承较单点支撑推力轴承具有的较好的工作性能。

dimesional therinoelastic flow dynamic lubricarion calculation of watercooling and double-layer Pads thrust bearing with rigid single-point spherical surface supports and thrust bearing with pivoted supports for hydrogenerators is conducted in this paper.The working behavior of the thrust bearing withpivoted supports being better than that of the bearing with single-point supportsis analysed and compared also.
