摘要:

研制适用于钢/钢摩擦副的含软金属Sn,Zn粉体的自修复润滑剂,在摩擦磨损试验机上考察该润滑剂的修复性能和摩擦学性能,用ANSYS软件仿真计算齿轮传动的齿面接触应力.研究结果表明,研制的Sn-Zn修复润滑剂可在钢表面摩擦形成修复层,在不同载荷下有良好的减摩和抗磨性能.仿真计算结果显示,该修复润滑剂可使修复齿面的接触应力降低16.7%.

Abstract:

A type of selfrepairing lubricant containing Sn and Zn powder additives and suitable for steelsteel tribopair is developed. Its repairing and tribological properties are reviewed on a rebuilding model MS800 tester. The tooth contact stress of gear transmission is calculated with ANSYS. The findings showed that repairing coatings can be formed on steel surface because of the SnZn selfrepairing lubricant, which has good antifriction and antiwear properties under different loads. Simulation results indicate that tooth contact stress is reduced by 16.7% after repairing with the lubricant.

Key words: soft metal additive; selfrepairing; gear transmission; friction and wear; contact stress
