helix angle

The helix angle is great generally that is close to about 45 °, this makes the cross helical gear be under to three-dimensional stress state after it is received strength;

交错轴斜齿轮的螺旋角一般较大，接近45°左右，这使得交错轴斜齿轮受力后处于三维应力状态；

The method of helix angle choosing of involute gears do not ensure hobbing precision. It cause large lead error.

这种选择往往在齿轮滚齿加工时，不能保证螺旋角β的精度，因而引起螺旋线偏差过大，接触时往往达不到全齿长的接触。
