The high-quality planetary reducer material can effectively extend the service life of the planetary reducer. In view of the structural characteristics of the precision reducer and the load nature of the gears, hard toothed gears should be widely used. There are many heat treatment methods for obtaining hardened gears, such as surface quenching, overall quenching, carburizing quenching, nitriding, etc., which should be selected according to the characteristics of gear reducers. 1. Surface quenching Common surface quenching methods are high-frequency quenching (for small size gears) and flame quenching (for large size gears). When the surface hardened layer includes the root of the tooth root, its effect is very good. The hardness of the tooth surface can reach 45-55HRC. 2. Nitriding adopts nitriding to ensure that the gear achieves high tooth surface hardness and wear resistance under the condition of little deformation, and does not perform good finishing after heat treatment Increased carrying capacity. 3. Carburizing and quenching Carburizing and quenching gears have a relatively large load-bearing capacity, but the finishing process (grinding) must be used to eliminate heat treatment deformation to ensure accuracy. Carburized and hardened gears are usually alloy steel with a carbon fraction of 0.2% -0.3% before carburization. The hardness of the tooth surface is usually in the range of 58-62HRC. If it is lower than 57HRC, the hard surface strength is significantly reduced, and if it is higher than 62HR, it is brittle increase. The hardness of the carburized and quenched gear gradually decreases from the gear surface to the deep layer, and the effective carburizing depth is defined as the depth from the surface to the hardness of 5.25HRC. The role of carburizing and quenching in the bending fatigue strength of gears not only improves the hardness of the core, but also lies in the residual compressive stress on the surface. It can reduce the stress in the large compressive stress area, so the root of the tooth cannot be ground when grinding the tooth. If you want the service life of the planetary reducer, and the working performance is guaranteed, it is crucial to choose the heat treatment method of the planetary reducer.
