摘要
研究服役期间的车用弧齿锥齿轮齿面磨损,对各个载荷与磨损状态下单齿和全齿磨损的齿轮构建传动误差曲线,判断载荷与磨损程度引起的弧齿锥齿轮动态传动误差变化。优化齿轮的关键参数,利用非线性分析方式研究齿轮的动力学特性。研究结果表明:提高齿面磨损量时,动态传动误差上升,获得了更大最值;提高载荷后,拟合函数斜率和截距形成了更大绝对值;逐渐提高齿面磨损量时,形成了更大动态传动误差。当载荷提高后,曲线可以在更短时间内进入稳态阶段,大幅减小波动性,形成了更大动态传动误差绝对值。该研究对后续的锥齿轮齿形设计奠定一定的理论基础。
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.
