Abstract

When roller linear guide pair works, rollers in and out of load-bearing area can cause slider vibration and friction force change. Here, to control and reduce this change, the structural design method for rail guide surface of slider was studied. Combined with the principle of force-deformation when roller enters load-bearing area, a calculation model of guide surface based on the principle of "equal work" was established, and the parameter equation of guide surface was derived. The vibration performance of design-improved guide pair was tested and analyzed through tests. The test results showed that the optimized slider rail guide surface can effectively reduce slider vibration and motion noise.
