深沟球轴承装球口结构与工艺改进

在加工带装球口的单列深沟球轴承时,装球口的加工工艺为热处理前铣削加工,热处理后磨削加工。由于没有专用的磨削机床,无法进行自动磨削,操作者只能手持套圈在砂轮上进行磨削,使装球口锁量尺寸精度无法保证,散差较大,而且劳动强度大,安全性低。通过对加工工艺进行改进,解决了存在的问题;同时,改变了装球口角度,减少了钢球的挤压损伤,提高了轴承质量。

Improvement on structure and process of iflling ball notch of deep groove ball bearing

When processing single row deep groove ball bearings with a iflling ball notch, the processing technology of the iflling ball notch was milling before heat treatment, grinding after heat treatment.Because there is no special grinding machine, no automatic grinding, operators can only hold ring on the wheel for grinding ,so size accuracy for locking balls of the iflling ball notch cannot be guaranteed, the size distribution and the intensity of labor are big with low security. Through processing technology improvement, the existing problems were solved. At the same time, the iflling ball notch angle was changed, the steel ball squeezing damages were reduced to improve quality of the bearing.
