摘　　要：传统的滚珠丝杠副预紧力值是通过计算测量摩擦力矩或采集机床振动信号,属于间接测量,其操作烦琐、无法在线测量,且数值不够准确。本文提出一种在线测量预紧力产生应变方法,通过微处理器控制,实现数据测量及检测数据的本地存储,并将数据无线传输至云端服务器。实验表明:该系统能较好地测量预紧力,并通过无线传输发送至云端,为滚珠丝杆副预紧力的在线测量提供了一种新的方法。The traditional preload value of ball screw pair is measured by calculating the friction torque or collecting the vibration signal of the machine tool,which is an indirect measurement.Its operation is cumbersome,can not be measured online,and the value is not accurate enough.This paper proposes an online method to measure strain gen-erated by preload,which realizes local storage of data measurement and detection through microprocessor control,and transmits data wirelessly to cloud server.The experiment shows that the system can measure the preload well and send it to the cloud through wireless transmission,which provides a new method for the on-line measurement of the preload of ball screw pair.
