Accurate Examination of Measuring Methods Regulated by Japanese Industrial Standard for Rotational Accuracy of Rolling Bearings

摘要

In this paper, we researched the accurate examination of measuring methods regulated by Japanese Industrial Standard for rotational accuracy of Rolling Bearings. Two methods for measuring are regulated in the section about rotational accuracy. We produced a measuring apparatus based on measuring method 2 and measured angular contact ball bearing in various conditions. The results are summarized as follows. (1) Bearing's Radial Run-Out is considerably influenced by the shape of inner raceway. (2) Influence of weight and rotational speed is lower than method 1.
