任意载荷作用下高速滚动轴承的寿命计算

本文依据套圈滚道控制理论讨论了在任意载荷作用下高速运转的滚动轴承中滚动体的载荷分布、运动状态及轴承使用寿命等问题，并编制了计算机程序，该程序可以分析单个轴承，也可分析同一轴上的几个轴承；可进行静力分析，也可作动态静力分析。程序还考虑到任意载荷、对称载荷和单一的轴向载荷等不同类型载荷的作用，并分别进行了处理。在基本方程的求解中提出了新的计算方法，使得求解对初始点的要求比Newton法大为降低，且收敛性较好，收敛速度较快，应用本程序对某发动机中若干对轴承进行了分析，使用效果使人满意。

THE FATIGUE LIFE OF HIGH SPEED ROLLING BEARINGS UNDER ARBITRARY LOADS

This paper presents the load distribution, the motion of the rolling bodies and the fatigue life of high speed rolling bearings under arbitrary loads according to the raceway control hypothesis. The analysis has been programmed out. Using the program, a single bearing or several bearings mounted on one shaft can be analyzed. And the static of quazi-static analysis can be performed in considering and handling respectively arbitrary, symmetric loads and thrust load acting on the shaft. A new numerical method is also presented in solving those basic equations so that it has better convergence and the lower demand on the initial data than Newton-Raphson method. After we computed some bearing on a shaft in a type of engine by using this program, it shows that it is satisfactory in practice.
