双半内圈沟道的磨加工方法有组合和单片加工两种,各有其优缺点。本文在单片加工的基础上加以改进,其主要特点是先将半内圈车出3/4的沟道,沟道精磨后按沟位置进行分组,多余的工艺留重采用磨、研平面的方法除掉,内圈沟道偏移量通过尺寸链计算保证;沟道测量方法类似于向心推力球轴承套圈的测量;缺点是磨削平面的余量较大和增加了分组工序。 Double-half inner ring groove grinding process and a combination of two kinds of processing, each has its advantages and disadvantages. This paper is to improve on the basis of single-chip processing, the main feature is the first half of the inner car out of the channel 3/4, the channel after grinding groove position grouping, excess process weight with grinding, grinding plane Method to get rid of the inner ring channel offset through the size chain calculation guarantee; channel measurement method is similar to the radial ball thrust bearing ring measurement; disadvantage is the grinding plane margin and increase the grouping process.
