Thermal friction problem and its development: Part 2. The role of heat phenomena in fracture of tooth wheels of cylindrical involute gears of real dimensions

The local pattern of initial of fracture of machine parts is discussed and the practical significance of determination of the zone of manifestation is highlighted. The temperature is considered the main factor in the process of improvement of the thermal friction problem governing operation of a heavily stressed contact. The results of calculation of brakes with the method of thermal dynamics of friction and wear are demonstrated.
