4Do you know the processing characteristics of large and small modular gears?

Different from ordinary module gear processing, small module gear processing has the following 4 major characteristics:

1. Machining with fewer teeth.

In the small modulus gear transmission, in order to reduce the volume and obtain a larger single-stage transmission ratio, the number of teeth of the product is less.

2. Reasonable formulation of small module gear processing technology is a particularly important factor to ensure quality.

Because of the small modulus gear, the transmission torque is small, so in the product design, the strength calculation and rigidity check are generally not carried out.Gear moduleUsually selected by the structural size of the transmission mechanism.

The cutting force, clamping force, supporting force and other factors in the processing of small module gears sometimes causegearDeformation and fracture.

3. External factors such as vibration, impact force, temperature change, etc. will directly affect gear machining accuracy.

In the process of small-modulus gear processing, the influence of machine tool tangential error is small, and the gear radial accuracy and backlash accuracy are required to be high.

4. There are special requirements for the precision of tools and equipment for processing small modulus gears.

Because there are many types of meshing of small module gears, in addition to the commonly usedInvolute gearIn addition to meshing, there are various modified cycloid gear meshing and simplified meshing.

In order to ensure the accuracy of the product, the tooth profile curves of various gears must be processed correctly.
