丝杠支撑专用双列角接触球轴承外圈沟道精度检测方法

针对丝杠支撑专用双列角接触球轴承外圈沟道接近半沟型,现有测量技术无法准确测量沟道位置及两沟间距问题,应用轴承高度测量仪,通过制作标准样圈,分别测量轴承外圈两端单边装配高并控制在工艺设定范围内,间接实现轴承沟道位置、直径和沟心距形成的轴承成品组装综合影响因素良好控制,从而保证轴承总体装配精度。

Inspection Method of Outer Ring Raceway Precision of Double Row Angular Contact Ball Bearings for Ball Screw Supporting

As the outer ring raceway of ball screw double row angular contact ball bearings is close to semi-groove type, the existing measurement techniques cannot precisely measure the raceway position and space between. By means of bearing height measuring instrument,with the reference of master outer ring,separately measure the assembly height of outer ring at each side and ensure them to be in the process specification,therefore,comprehensive factors of raceway position,diameter and difference of raceway to center which affect bearing assembly quality,is indirectly well controlled. Eventually,ensure the overall assembly precision of bearings.
