摘 要: 以冲击电钻小模数变速齿轮为研究对象,采用有限元方法研究,冲击电钻在堵转时所引起的不同的冲击载荷和冲击时间,对小模数齿轮齿根动态应力的影响,并分析比较在相同的静载荷作用下的静应力状态,以及不同的齿根过渡曲线对齿轮强度的影响。 The dynamic stress response of the small module gear is analyzed under impact load by means of finite element method. Analyzing the tooth root stress of small module gear under different impact load and impact time, the curve of dynamic stress in different time is obtained. In order to compare, the static stress of tooth root under stable load is also analyzed. The stress of tooth root and transition curves of tooth root is analyzed using different fillet radius. The curves of variation of stress with different fillet radius is given. Thus the optimum fillet of tooth root can be specified.
