摘　　要：首先从理论出发,介绍了滚珠丝杠副的表面加工质量,分析了滚珠丝杠副摩擦力矩的构成,并给出了相应的计算公式;然后给出了摩擦力矩测量试验方案以及测量系统的组成,在此基础上开展了针对不同表面粗糙度的滚珠丝杠副摩擦力矩测量试验。试验结果表明:滚珠丝杠副的摩擦力矩会随着表面粗糙度的增大而增大;并且丝杠表面粗糙度从0.3μm增加到0.6μm产生的摩擦力矩波动要大于表面粗糙度从0.6μm增加到0.9μm产生的摩擦力矩波动。Firstly,starting from the theory,the surface machining quality of ball screw is introduced,the composition of friction moment of ball screw is analyzed,and the corresponding calculation formula is given.Then the scheme design of the friction torque measurement test and the composition of the measurement system are given.On this basis,the friction torque measurement test of ball screw pairs with different surface roughness is carried out.The experimental results show that the friction torque of ball screw increases with the increase of roughness.And the friction torque fluctuation generated by the increase of the surface roughness from 0.3μm to 0.6μm is greater than that generated by the increase of the surface roughness from 0.6μm to 0.9μm.
