| Abstract: | 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. |
