The Research on the Crowned Rollers of Cylindrical Roller Bearings

1、

Based on a systematical discussion on the theoretical research methods of crowned design in roller bearing, several crowned types adopted in the engineering practice are introduced in this paper, and research direction in the future is illustrated based on the authors' experience.

在系统沦述滚动轴承滚子凸度设计研究方法的基础上，介绍了工程实际中采用过的几种滚子凸型，给出相应的母线方程和表面间隙表达式，并阐述了今后的研究方向。
