The difference between precision gear processing and helical gear processing

The difference between precision gear processing and helical gear processing


The following introduces the difference between precision gear processing and spiral gear processing:

1. Because the engagement surface reaches from small, the engagement is stable, the impact is small, and the noise is small;

2. Large carrying capacity, improve life and stability;

3. Small gears are not easy to cut, and the volume is small;

4. But the axial thrust is large, the herringbone gear-no axial thrust, but it is troublesome


The helical gear transmission is composed of two helical pinions meshing. Uses: To transfer the movement between two staggered axes in space. Features:

1. The spiral direction can change the center distance and transmission ratio

2. Steering can be changed by spiral rotation

3. Fast wear

4. Point contact

5. Low axial force


Commonly used gear tooth processing methods

There are two types of processing methods for gear tooth profile, whether there are chip processing and cutting processing.

Chipless processing methods are: hot rolling, cold extrusion, die forging, precision casting and powder metallurgy.

Cutting methods can be divided into two methods: forming method and forming method, and their machining accuracy and application
