gear contact ratio

基本解释

The investigate characteristic of system vibration and effects of contact ratio, gear number on dynamic mesh force were discussed.
在此基础上分析了不同速度（频率）对系统振动的影响，并研究了重合度、齿数与系统动态啮合力之间的关系。
High tooth gear has small module, small pressure angle, and large addendum to enlarge the transverse contact ratio, improve gear strength, and reduce the noise.
细高齿齿轮是采用小模数、小压力角、大齿顶高来加大端面重合度，达到提高齿轮强度、降低噪声的目的。
After getting the formula about the normal backlash and the stiffness of the tooth pairs of the gear, the contact ratio and the load correction factor could be obtained.
在获得齿轮内啮合传动的齿侧间隙计算公式以后，结合齿对刚度的计算公式，推导出齿轮内啮合传动的加载重合度及载荷修正系数。
