Wear experiment and model of rolling balls in sliding-rolling conditions
Mechanics & Industry, 2017 When the rolling bearing is working, sliding and rolling always exist in the friction pair simultaneously. The operating condition is complicated and fickle. For these kinds of behaviors, it is necessary to simulate the bearing sliding-rolling ratio (SRR), load, speed and other operating parameters in the wear-testing research between the rolling ...
