摘要影响滚珠丝杠使用性能和使用寿命的因素有很多，最主要的是因加工产生的滚道型面几何尺寸误差，因使用前加载的预紧力产生的摩擦力矩以及工作中采用的润滑方式。同时，滚道型面几何误差、摩擦力矩与润滑方式这几个因素之间也存在相互的影响关系。63512

Title The Design of Ball Screw Test-bed Based on Raceway Surface,Friction Torque,Lubrication Fundamental Research
Abstract There are many factors which affect the usability and the working life of ball screw. The dimension error of raceway surface generated by processing and the friction torque generated by preload and the method of lubrication are the leading factors. Meanwhile,there is much relationship among the dimension error of raceway surface,friction torque and lubrication method. The design of synthesizing type fundamental theory test-bed in this paper is used to study the relationship among the dimension error of raceway surface,friction torque and lubrication method and to improve the usability and the working life of ball screw. The design is mainly work out the combination of the measurement between raceway surface and the friction torque,and finish the integrated design of the ball screw test-bed,and finish the selection of the sensor of raceway surface measurement/friction torque measurement and the schematic design of measurement and control system.
Keywords ball screw raceway surface friction torque lubrication test-bed
