为了确定载货汽车齿轮的失效原因,苏联汽车拖拉机材料科学研究所,在资料分析和试验数据的基础上进行了一系列的工作。在工作过程中,汽车齿轮承受静、动和循环载荷以及在高比压力下的磨损作用。汽车变速器和后桥齿轮所受的应力尤其大。大量的、各种齿轮的失效分析表明,齿轮的损坏基本上是在循环拉伸应力、接触应力、静 In order to determine the cause of the failure of the truck gear, the Soviet Union Institute of Automotive Tractors Materials, based on data analysis and experimental data carried out a series of work. In the course of their work, automotive gears withstand static, dynamic and cyclic loads and wear under high specific pressures. Automotive transmission and rear axle gear are particularly stressed. A large number of gear failure analysis shows that the gear damage is basically cyclic tensile stress, contact stress, static
