摘要

the utility model belongs to the field of testing for the design of rigid u0438u0437u043du0430u0448u0438u0432u0430u043du0438u0435 and u043au043eu043du0442u0440u043eu0431u0440u0430u0437u0446u0430 friction pair, designed to test them at all u0438u043au0446u0438u043eu043du043du0443u044e fatigue.u043au043eu043du0442u0440u043eu0431u0440u0430u0437u0435u0446 is in the form of a disc, the end surface of which is equipped with u0438u043du0434u0435u043du0442u0435u0440u043eu043c with rounded top. at the end of the disc is a ring canal.u0438u043du0434u0435u043du0442u0435u0440 implemented as entrenched in the balls, and the length of the grooves on its average diameter.as well as her profile cross section selected from the conditions of u0431u0435u0437u0437u0430u0437u043eu0440u043du043eu0433u043e interface in a number of the balls within the ball on a disk surface and segmentsheight of not more than the radius of the sphere. technical result: an opportunity to reduce the test time to develop the necessary base cycles. 1 il.
