The relationship and characteristics between helical gears and helical gears

1、 Advantages and disadvantages of helical gears

Because the meshing surface is from small to large to small, the meshing is smooth, the impact is small, and the noise is low;

2 major load-bearing capacities, improving lifespan and stability;

3zmin is small and difficult to root cut, with a small volume;

4. However, the axial thrust is large, and the herringbone gear has no axial thrust, but it is difficult to manufacture.

2、 Spiral gear transmission is composed of two helical gears meshing with each other.

Purpose: To transmit motion between two misaligned axes in space.

characteristic:

1. Spiral direction can change the center distance and transmission ratio

2. The steering can be changed by spiral rotation

3. Wear block

4. Point contact

5. Small axial force
