Technical Field

[0001] This invention relates to the field of planetary gearbox gear repair equipment design technology, specifically a planetary gearbox gear repair equipment and repair method. Background Technology

[0002] A planetary gear reducer is a power transmission mechanism that uses gears to reduce the rotational speed of a motor to a desired speed while obtaining a larger torque. In a planetary gear reducer, the gear with fewer teeth on the drive shaft meshes with the larger gear on the output shaft to achieve speed reduction. Ordinary speed reducers also use several pairs of gears meshing on the same principle to achieve the desired speed reduction effect. The ratio of the number of teeth on the large and small gears is the transmission ratio. As the name suggests, planets revolve around a star; therefore, a planetary gear reducer has three planetary gears rotating around a sun gear. With the rapid development of the planetary gear reducer industry, more and more industries and companies are using planetary gear reducers.
