Originální abstrakt

This paper is focused on the roughness induced effects in EHL contact under high sliding conditions when thermal effects can be expected. High sliding conditions include both the case when both surfaces are moving in the same direction and that when they move in the opposite directions. The presented results show that increasing magnitude of sliding connected with high in-contact temperatures has almost no effect on roughness deformation until the dimple phenomenon occur. The observations of film variations evolution, caused by roughness pass (complementary effect), can give information about flow processes in an EHL contact under dimple phenomenon conditions. Essentially different behavior was observed in a classic EHL contact and in a contact when dimple phenomenon has occurred.
