How to choose the material of the gear box gear of the reduction motor?

The reduction gearbox's movement is influenced by the material of the gear, which also has an impact on the transmission's efficiency and gearbox durability. Let me explain how to choose the reduction gear box gear's material.

1. Steel that has been quenched and tempered, such as 35CrMn and 40CrMoA. Steel's surface hardness possesses high strength and toughness once it has been quenched and tempered. It is appropriate for gear transmissions operating at medium speeds and loads. The surface hardness can achieve HRC45-HRC55 if it is quenched and tempered in accordance with quenching and tempering treatment. It is appropriate for gear boxes that have larger loads.

2. Carburizing steel, including 12Cr2Ni4, 20CrMo, and 20CrMnTi. After being carbureted, this type of steel has a high surface hardness, making it a popular choice for gearboxes that need a large bearing capacity and strong impact resistance.

3. Nitrided steel, including 30CrNi3, 18CrNiWA, and 30CrMnSi. These steels are ideal for high-precision and high-strength gear transmission pairs due to their exceptionally high surface hardness of 56HRC to 60HRC after nitriding.
