基于双平面研磨方法的圆柱滚子抛光实验研究

Polishing Process study of Cylindrical Rollers by Using a Double-Side Lapping Machine

圆柱滚子的表面质量对轴承的性能、寿命有重要的影响。本文在双平面研磨机上结合绒布抛光垫对圆柱滚子表面进行了抛光。经过20 min时间的抛光,圆柱滚子表面质量得到了极大的改善,获得了镜面加工效果,并且圆柱滚子的圆度有了0.3μm的提高。实验结果表明了基于双平面研磨机上的圆柱滚子抛光实验可以略微改善工件圆度,有效地提高圆柱滚子表面质量。

Cylindrical roller is the key part of roller bearing, and the surface quality of cylindrical rollers has great influence on the working life of rolling bearings. Double-side lapping machine and flannelette pads were applied to polish the cylindrical surface of rollers. After 20 minutes of polishing, roundness of the rollers had an improvement of 0.3 μm. The surface quality was improved, and the rollers with smooth surface were obtained. The results shows that the polishing test of the cylindrical roller can improve the roundness and surface quality effectively.
