摘要
归纳整理了数控机床进给系统轴承预紧和滚珠丝杆预拉伸的关键技术参数计算式,对角接触球轴承预紧和滚珠丝杆预拉伸的装配要求进行了讨论,提出了测定轴承预紧量和丝杆拉伸量的实验方法,给出了某进给系统轴承预紧与丝杆拉伸装配的关键技术参数计算实例。
This paper tends to sort out the key technical data computing formulas of the ball bearing preload and the ball screw pre-stretched, and discusses the requirements of CNC feed system assemble. A testing way is advanced to measure the value of the ball bearing preload and the ball screw pre-stretched. An example is cited by way of explanation.
