Classification method of planetary gear reducer according to gear meshing The classification method of planetary gear reducer can be classified according to the standard of planetary gear reducer JB 1977-1976 of the Ministry of Machinery Industry. It has adopted the classification of planetary gear transmission according to its meshing mode. This classification method usually uses the following basic code:
N——Internal gear pair W——External gear pair G——Common gear that meshes with the two center wheels at the same time According to the meshing mode of the planetary gear transmission, the transmission type of the planetary gear transmission can be divided into:
NGW - a planetary gearing NW with internal and external meshing, but also a common gear - a planetary gearing WW with internal and external meshing - with two externally meshed planetary gearing NN - Planetary gearing NGWN with two internal meshes - a planetary gearing N with two internal and one external meshes, and also a common gear - only one planetary gearing with a planetary gearbox The model number is also indicated as above, and the machine can be selected according to the needs and environment.
