The tooth surface wear of vehicle spiral bevel gear during service was studied,transmission error curves were constructed for single and full gear wear under different load and wear conditions,and the dynamic transmission error changes of spiral bevel gear caused by load and wear degree were judged.The key parameters of the gear were optimized and the dynamic characteristics of the gear were studied by nonlinear analysis method.The results show that when the tooth surface wear is increased,the dynamic transmission error increases and the maximum value is obtained;after increasing the load,the slope and intercept of the fitting function form larger absolute values.When the tooth surface wear is gradually increased,the dynamic transmission error is larger.When the load is increased,the curve can enter the steady-state stage in a shorter time,greatly reducing the volatility and forming a larger absolute value of dynamic transmission error.This study lays a theoretical foundation for the subsequent design of bevel gear tooth profile.
