Using the lubricants with solid additives in the sliding support with the reverse movement of the shaft

Possibility of increase in durability of sliding supports which working surfaces in the mode of reverse movement are exposed to considerable wear because of impact of sign-variable shift deformations is considered. The purpose of work consists in assessment the efficiency of using lubricants with solid additives of ultradisperse diamond-graphite for decrease in wear of details in the conditions of reverse friction. Results of research the influence of lubricants at a size of friction forces and intensity of wear of samples are given. The analysis of condition of friction surfaces and change of microrelief after using the studied lubricants is made. The received results showed efficiency of using the lubricants with ultradisperse powder of diamond-graphite. Results of researches can be applied to choice the lubricants which are used for the knots of friction working in the mode of the sign-variable movement.
