因此，几何变化或失败而高接触应力和过度磨损或许是可以避免的。
Thus, geometric changes or failure due to high contact stresses and excessive wear may be prevented.
准双曲面齿轮与普通圆锥齿轮相比，具有重合度大、齿面接触应力低、传动平稳、冲击和噪音小、承载能力高和寿命长等优点。
Compared to bevel gear, hypoid gear has larger overlap coefficient, lower gear contact stress, more smooth transmission, lower impact and noise, higher load bearing capacity, longer life and so on.
由于模具在非常高的接触应力下工作，其寿命大为缩短，因此，锻件的制造成本也不断提高。
For working under extremely high of contacting stress, long service life of dies would be shortened.
本实用新型具有传动效率高，接触应力小，承受载荷大，结构简单，制造、装配方便，成本低廉等优点。
The utility model has the advantages of high driving efficiency, simple structure, convenient assembly and manufacturing, low cost, small contact stress, big absorbing load, etc.
