轮毂球轴承(第一代)沟间距测量仪器改进

Improvement of measuring device for distance between grooves of hub ball bearing(the first generation)

针对轮毂轴承沟间距测量较为困难的情况,对测量推力球轴承沟径及径向跳动的检查仪器(D802)进行改装,满足了生产和工艺要求。

To counter the difficulties in measuring the distance between grooves of hub bearing,the measuring device （D802） used for determining the groove diameter and radial runout of thrust ball bearing was improved so as to meet the requirements of production and technology.
