调心球轴承外沟沟位置的测控

Measuring and Control of Grove Raceway Position of Self-Aligning Ball Bearing Outer Ring Grooved Raceway

利用调心球轴承的外沟分别以正反端面为基准在同等固定高度下所测得的直径差，随沟位置的变化而变化的规律，把对外沟沟位置的测量与控制转化为固定高度的两端直径差的测量与控制．实践表明效果很好。

Using outer ring grooved raceway of self - aligning ball bearing and taking its obverse and reverse side of end face as datum respectively, the diameter difference is measured under equal fixed height. Utilizing law of change of the diameter difference with change of the raceway groove, position can convert measuring and control of raceway groove position of outer ring grooved raceway to measuring and control of two end face diameter difference under fixed height. Practive shows that its effect is very good.
