摘　　要：行星减速机背隙大小是影响减速机传动精度和运动平稳性的重要指标,也是划分减速机传动精度等级的主要参数,针对目前背隙检测设备普遍存在的扭矩加载不精确、兼容性不强、测量效率不高等问题,研制了一种减速机背隙自动检测装置。首先,设计了一种结构简洁、适用于多种机型检测的机械结构,提高了装置的兼容性;然后,结合精密伺服系统和高精度扭矩传感器,构建了扭矩加载闭环反馈系统,实现了扭矩精确动态加载;开发了PLC控制系统,实现了检测工作过程的自动化,提升了检测工作效率;最后,设计了对比测量实验,并对装置进行了测量系统分析。研究结果表明:该测量装置的重复性和再现性GRR为0.218,总变差TV为1.219,测量变差占过程总变差百分率%GRR值为17.9%,说明该装置检测性能良好,可用于中等精度减速机背隙的检测。The backlash of the planetary reducer was an important index that affected the transmission accuracy and smoothness of the reducer,and it was also the main parameter for dividing the accuracy grade.Aiming at the problems of inaccurate torque loading,poor compatibility,and low measurement efficiency that were common in backlash detection equipment,an automatic detection device for the backlash of the reducer was developed.First,a mechanical structure with a simple structure and suitable for operation of multiple models was designed to improve the compatibility of the device;then combining the precision servo system with the high-precision torque sensor,the torque loading closed-loop feedback system was constructed to realize the precise and dynamic torque loading,and the PLC control system was developed to realize the automation of the work process and improve the detection efficiency.Finally,a comparative measurement experiment was designed,and the device was analyzed for the measurement system.The test results show that the repeatability and reproducibility of the measurement device is 0.218,the total variation TV is 1.219,and the measurement variation accounts for the percentage of the total variation in the process.The GRR value is 17.9%,indicating that the device has good detection performance and can be used to detect the backlash of a medium-precision reducer.
