Surface treatment technology of planetary gear reducer 2021-08-29
Surface treatment technology of planetary gear reducer Selecting high-quality planetary gear reducer materials helps to improve its load-carrying capacity and service life.In view of the structural characteristics of the Xinghe reducer and the load characteristics of the gears, hard-toothed face gears should be widely used.There are many heat treatments available to obtain hardened gears.For example, surface quenching, overall quenching, carburizing quenching and nitriding should be selected according to the characteristics of the gear reducer.1. Surface hardening The common surface hardening methods are high-frequency quenching (for small gears) and flame quenching (for large gears).Works well when the case-hardened hardened layer includes the bottom of the dedendum.The hardness of the tooth surface can reach 45-55HRC.2. Nitriding and nitriding can ensure high hardness and wear resistance of gears with small deformation, and can not be well finished after heat treatment to improve bearing performance.3. Carburizing and quenching Carburizing and quenching gears have a large load-carrying capacity, but finishing (grinding) must be used
