What is the difference between the working principle of a hard tooth gear reducer and a regular gear reducer

The working principle of hard tooth surface gear reducer is completely the same as that of ordinary (soft tooth surface) gear reducer, both relying on gear meshing transmission to achieve the purpose of reducing speed and increasing torque. The driving gear drives the driven gear, and the transmission structure and basic working mode are no different.

The main difference between the two lies in the gear performance and application characteristics:

1. Different tooth surface strengths: Hard tooth surface gears undergo carburizing, quenching, and grinding treatment, resulting in high hardness and good wear resistance; Ordinary soft tooth gears have lower hardness due to quenching and tempering or normalizing treatment.

2. Different bearing capacity: Under the same volume, the bearing capacity of hard tooth surface reducers is much greater than that of soft tooth surface reducers.

3. Different structures and accuracies: Hard tooth surface reducers have small volume, light weight, high transmission accuracy, and low noise; Soft tooth surface reducers have a relatively large volume, average accuracy, and relatively high noise.

4. Applicable working conditions are different: Hard tooth surfaces are mostly used in heavy-duty, continuous operation, and high impact situations; Soft tooth surface is suitable for light load, intermittent, and low-cost ordinary working conditions.
