摘　　要：滚动直线导轨副是高速高精度数控机床的重要功能部件,其摩擦特性对机床整机的力学特性具有重要影响,因此对导轨摩擦力的大小进行检测具有重要的意义。针对摩擦力检测要求,设计了一种自动检测滚动直线导轨副摩擦力的试验装置,将测量结果与手动测量进行对比,并对某一型号的滚动直线导轨副进行重复性测试,验证了该测量方法的可靠性。针对35和45型号的滚动直线导轨副进行不同速度条件下的摩擦力测试,试验结果表明,随着速度增加,导轨副摩擦力有先减小后增大的趋势。Linear rolling guide is an important Functional part of high-speed high-precision CNC machine,its great influence on the mechanical properties of the friction characteristics of the whole machine,so the size of rail friction detection is of great significance. For friction test requirements,This paper presents a automatic detection of roller linear guides friction testing device,the measurement results were compared with manual measurements,and repetitive testing for a certain type of linear Rolling guide,verify the reliability of the measurement method. The friction testing conditions at different speeds for 35 and 45 models rolling linear rolling guide,test results showthat with the increase in speed,the friction have after the first decreases and then increases.
