为了准确地保证每套轴承装配后的允许径向游隙值,提高轴承零件尺寸选择装配的效率和合套率,作者介绍一种球轴承零件尺寸选择装配用的计算转盘,应用这一工具,在内、外圈沟径和钢球直径公差这三个因素中,已知任意二个,在某一型号轴承的径向游隙条件下,便能迅速而准确地求得第三个零件的尺寸公差值。文章介绍了计算转盘的设计原理、使用方法以及制作要点等。附图1幅。
In order to accurately guarantee the allowable radial clearance after assembly of each bearing, and to improve the efficiency and fit rate of bearing parts, the author introduces a calculation turntable for ball bearing part size selection and assembly. With this tool, Inner and outer ring groove diameter and ball diameter tolerance of these three factors, known to any two, in the radial clearance of a certain type of bearing conditions, you can quickly and accurately get the size of the third part Tolerance value. The article introduces the calculation of dial design principles, methods of use and production points and so on. Figure 1 picture.
