In this study, Effect of Molybdenum disulfide (MoS2), Anglamol(SP) and Tricresyl phosphate(TCP) additives on the tribological performance of loosing and tightening process of screw and nut were investigated by using a self-developed tribological tester. The screw and nut are made of SCM 440 and HBsC3, respectively.
Result shows that the MoS2 additives with Grease#0 give the best tribological performance but TCP with Grease#0 is worst. With increasing concentration of MoS2 , the lubricant life increases, reaches a maximum at about 5wt% and finally diminishes with decreasing. Surface pressure between the screw and nut, the lubricant life increases. Under the surface pressure of 2.64kg/mm2, the lubricant life can achieve 8000 cycles or more. To maintain the long life of the screw and nut, the surface pressure should be equal to or less than 2.64kg/mm2.
