浪形保持架在轴承内径向位移量的计算分析

Calculation for radial dis-placement of bearing ribbon cage

通过对保持架、钢球和套圈沟道之间几何关系的分析计算,建立了浪形保持架在轴承内的径向位移量的计算公式;而《球和滚子轴承设计标准》(1958年版)第23页上,介绍的浪形保持架在轴承内的径向位移量计算公式,仅是在特定条件下的兜孔径向游隙计算公式。

After some analysis and calculation of geometric relationship between cage, ball and raceway, a formula for calculating the radial displacement of ribbon cage in bearing was set up. It is different from the expression introduced in 'Ball & Roller Bearing Design standards' (Published in 1958), the latter is only suitable for calculating the radial clearance of cage pocket on a special condition.
