摘要
为研究齿面磨损对齿轮系统动态特性的影响,综合考虑齿轮齿侧间隙、传输误差、齿面磨损,采用集中参数法建立齿轮平移-扭转非线性动力学模型,分析齿轮的转速、运行次数对含有齿面磨损的齿轮传动系统动态特性的影响。结果表明:在啮合区域内,齿根处的齿面磨损量呈减小趋势,在节点处理论磨损量为零,齿顶处的齿面磨损呈增加趋势,齿面磨损量减小趋势大于增加趋势,整个过程中齿面磨损会造成啮合刚度的减小;存在齿面磨损时,过大或过小的转速都会使齿轮系统的振幅波动变大,幅值减小;当转速一定时,含有齿面磨损的系统随着运行次数的增加,振幅幅值会逐渐减小,传动的波动会加剧。
To study the effect of tooth surface wear on the time-varying mesh stiffness of gear pairs,by considering the gear tooth side clearance,transmission error and tooth surface wear,the gear-shift-torque nonlinear dynamic model was established by the lumped parameter method.The effect of the gear speed and the number of runs on the dynamic characteristics of a gear train with tooth surface wear was analyzed.The results show that in the meshing area,the wear of the tooth surface at the root of the tooth is decreased,the wear of the tooth at the node is zero,and the wear of the tooth surface at top of the tooth is increased.The decreasing trend of the tooth surface wear is greater than the increasing trend.During the whole process,the tooth surface wear will cause the reduction of meshing stiffness.In the case of tooth surface wear,too large or too small rotation speed will increase the amplitude fluctuation of the gear system and decrease the amplitude.When the speed is constant,with the increase of operating times,the amplitude of the system with tooth surface wear will gradually decrease and the transmission fluctuation will be intensified.
