How does the surface roughness of gear rack affect the performance?

Relevant research and test data show that the surface roughness of gear rack affects the efficiency of components, not only increases the wear rate, but also has more or less influence on the following three aspects.

齿轮齿条

1. The influence of friction loss and transfer efficiency

The smaller the roughness, the smaller the friction loss and the smaller the power loss

2. Impact on lubrication status

The smaller the roughness is, the larger the oil film bearing capacity is, and the smaller the tooth surface wear is

3. Impact on noise

The lower the roughness is, the lower the meshing noise is.

4. Impact on friction factors

The smaller the roughness is, the smaller the contact area between the convex peaks of the tooth surface roughness is, and the friction factor is smaller.

5. Influence on fatigue and bearing capacity

The smaller the roughness is, the longer the fatigue life is, and the greater the bearing capacity is
