4 Description of basic technical requirements for large and small modular gears (for reference)

Although the purpose of the small module gear transmission mechanism is different, the requirements for the gear will be different, but the basic four major technical requirements are still the same, respectively as follows:

1. Work smoothly

To control the change of the instantaneous transmission ratio.

In the process of transmitting motion, it must be required to work smoothly, without impact or noise, especially for high-speed runninggear.

2. Motion accuracy

The transmission movement is accurate and reliable, and the movement of the driven wheel and the driving wheel are coordinated to ensure that the rotation angle error in one revolution does not exceed the allowable range.

3. Reasonable tooth side clearance

In order to store lubricating oil, compensate for elastic deformation, temperature and gear manufacturing errors caused by backlash changes, to prevent the product from appearing "stuck".In the transmission process, there should be a certain gap between the non-working surfaces of the two meshing teeth,

However, the backlash also needs to be rationalized and not too large, so as not to cause "backlash" in the transmission.

4. Good contact performance

In order not to cause excessive contact stress due to uneven contact and cause premature wear of the tooth surface, when the load is transferred, the gear working surface should have enough meshing contact surface.

The above is the description of the basic technical requirements of small modulus gears for reference.
