短沟距双沟道轴承心轴加工方法

The Processing Method of the Mandrel of Double Raceways Bearing with Short Channel Spacing

为了提高短沟距双沟道轴承心轴的加工精度及生产效率,介绍该心轴的初始加工方案,分析其沟道加工难点以及传统单沟道翻转磨削方法加工精度差、报废率高、磨削效率低、产品装配困难等缺陷,提出短沟距双沟道轴承心轴改进加工方案及其工艺流程、尺寸控制标准。指出:改进方案通过两根心轴组合交错磨4沟道工艺,有效提高了零件的加工精度和磨削效率,满足大批量生产要求。

In order to improve the machining precision and production efficiency of the mandrel of double raceways bearing with short channel spacing.Introduction is made to the initial processing scheme of mandrel, analysis is done to the difficulties of channel processing and the defects of the traditional processing method of single channel roll-over grinding, such as poor machining precision, high scrap rate, low grinding efficiency, product assembly difficulties and such.The improvement of processing scheme,process flow, size control standard is done to the mandrel of double raceways bearing with short channel spacing. It is pointed out that the improvement scheme through two mandrel combination staggered grinding four channel, it can effectively improve the machining precision and grinding efficiency,and meet the requirements of mass production.
