The gear force mode of the reducer

In the gearbox of the reducer, its input bearing bears the axial force and torque transmitted by the motor shaft. The gears on the intermediate shaft receive torque from the input, braking torque from the output when braking, and braking torque from the output when braking. The gear on the output shaft bears the torque from the intermediate shaft, and also bears the braking torque from the output end when braking.

The commonly used materials and properties of the gears of the reduction box; in the reducer, the commonly used material of the gear is low-carbon alloy steel, and the material of the gear of the reducer is carburized steel. The performance requirements of carburized steel are as follows.

1. The ability to accept carbon should be strong, the surface can absorb a sufficient amount of carbon; the infiltration speed is fast; the carbon concentration gradient is gentle; sufficient hardness, strength and toughness.

2. The overheating sensitivity should be small. When heated for a long time at the carburizing temperature, the austenite can still maintain a fine-grained state, so as to realize direct quenching and prevent the mechanical properties from deteriorating due to coarse martensite grains after quenching. .

3. It must have sufficient permeability to ensure that the core has high yield strength and toughness after quenching; in addition, a moderate cooling medium can be used to greatly reduce the possibility of deformation and cracking of carburized parts.

4. Low carbon alloy steel is not allowed to have serious band structure, and coarse inclusions and cracks are not allowed, especially on the surface of carburized layer.
