Wear of metals in lubricated joints operating in start–stop mode

Abstract

Friction and wear regularities of the bronze-steel joint have been studied during continuous sliding and friction with recurrent start and stop periods. The test results for friction without cooling and constant temperature of the lubricating material have been compared. Under the conditions of the forced cooling of the oil, transfer from continuous to periodic sliding is accompanied by a growing coefficient of friction and the wear rate of the bronze counterbody. Under conditions without cooling and in certain loading modes, the reverse scenario is probable.
