在球状轴系中,球和球瓦是旋转运动的基准,因此球和球瓦的不圆度,以及它们与钢珠之间的尺寸合理选择等是决定旋转精度的主要环节,也成为加工工艺的关键。目前球和球瓦加工的方法,根据各工厂的设备条件也可选择不同方法。就我所试制过的整球和半球轴系来说,在加工过程中根据摸索和学习有关兄弟单位加工的经验,进行逐 In the ball shaft system, the ball and the ball is the base of the rotary motion, so the ball and the ball non-roundness, and the size of the ball with the ball between the reasonable choice is the main part of the rotation accuracy, but also become a processing technology The essential. The current ball and ball tile processing methods, according to the plant equipment conditions can choose different methods. In my trial of the entire ball and hemispherical shaft system, in the process of processing according to groping and learning about the brother unit processing experience, by
