Heat treatment method of planetary reducer
Choosing good material of planetary reducer is conducive to improving the bearing capacity and service life of gear reducer. In view of the structural characteristics of precision reducer and the load characteristics of gears, hard tooth face gears should be widely used. There are many heat treatment methods to obtain hard face gear. For example, surface quenching, whole quenching, carburizing quenching and nitriding should be selected according to the characteristics of gear reducer. 1. Surface hardening The common surface quenching methods are high frequency quenching (for small size gears) and flame quenching (for large size gears). When the hardened layer of surface hardening includes the bottom of the tooth root, the effect is the best. The hardness of tooth surface can reach 45-55HRC. 2. Nitriding The application of nitriding can ensure that the gear can achieve high hardness and wear resistance under the condition of minimum deformation. After heat treatment,
