摘要

从角接触球轴承内部的几何关系入手

建立了用于分析高速精密角接触球轴承旋转精度的五自由度拟静力学模型.考虑了离心力、陀螺力矩、润滑以及加工误差等

如波纹度的影响

并通过数值迭代方法的求解

着重分析了分布于内外圈沟道及球上的波纹度对角接触球轴承非重复性跳动的影响规律.研究发现

轴承套圈上只有特定阶数的径向和轴向波纹度组合才会使角接触轴承产生十分明显的径向非重复性跳动.对于单一球上存在波纹度的情况

只有当波纹度阶数为偶数时才会对轴承的旋转精度产生十分明显的影响

而奇数阶波纹度几乎不会使轴承产生径向非重复性跳动

并且非重复性跳动值随着球数的增多而减小.

Abstract

A five-degree-of-freedom quasi-static model based on the internal geometric relationship is developed to analyze high speed precision angular contact ball bearings'running accuracy. It takes the centrifugal force

gyroscopic moment of balls

lubrication and manufacturing inaccuracy such as waviness into consideration. A numerical iterative program is adopted to solve the problem. The emphasis of this paper is placed on the influence of running surface waviness on angular contact ball bearings'radial non-repeatable runout. It's found that the radial non-repeatable runout of the bearing rotation center is remarkable only when specific combinations of orders of the radial and axial waviness on the bearing rings are met. For the case of existence of waviness on only one ball

the running accuracy will be affected obviously only when the waviness order is even

but not when that is odd

and the radial non-repeatable runout decreases as the number of balls increases.
