摘      要：Rolling contact fatigue(RCF)issues,such as pitting,might occur on bevel gears because load fluctuation induces considerable subsurface stress *** issues can dramatically affect the service life of associated *** accurate geometry model of a hypoid gear utilized in the main reducer of a heavy-duty vehicle is developed in this study with the commercial gear design software *** stress–strain states are simulated with the finite element method,and the RCF life is predicted using the Brown–Miller–Morrow fatigue *** patterns of fatigue life on the tooth surface are simulated under various loading levels,and the RCF S–N curve is numerically ***,a typical torque–time history on the driven axle is described,followed by the construction of program load spectrum with the rain flow method and the Goodman mean stress *** effects of various fatigue damage accumulation rules on fatigue life are compared and discussed in *** results reveal that the Miner linear rule provides the most optimistic result among the three selected rules,and the Manson bilinear rule produces the most conservative result.
