镶嵌用固体润滑剂对锡青铜轴承摩擦学性能影响的研究

The Effect of embedded Solid Lubricant on the Tribological Properties of Tin-Bronze Bearings

摘要: 用端面摩擦试验机考察了几种镶嵌用固体润滑剂及添加剂在常温条件下对锡青铜轴承摩擦磨损性能的影响,并用X-射线衍射法、俄歇电子能谱法分析了摩擦表面转移膜的化学组成和结合情况。结果表明,几种固体润滑剂的嵌入均可提高轴承的耐磨性,并对减小摩擦系数有一定的作用;摩擦表面固体润滑剂转移膜的形成能够有效地减少摩擦副表面间的粘着现象,是改善轴承摩擦磨损性能的主要原因。

Abstract: The effects of several embedded solid lubricants and additives on the friction and wear properties of tin-bronze bearings under room temperature are examined by using an end-face friction test machine, moreover, the chemical compositions and combinations of transfer film of friction surfaces are analysed by X-ray diffraction and Auger electron spectroscope. The results show that PTFE, MoS2 and graphite as solid lubricants of tin-bronze bearings can reduce the friction and wear under dry friction. The transfer film of solid lubricant on friction surface can reduce effectively the adhesion of surfaces of friction pairs.
