Technical Field

[0001] The invention relates to the technical field of planetary gear processing, in particular to a tooth profile positioning milling device for producing planetary gears of a reducer. Background Art

[0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. According to its use, the reducer can be divided into two categories: general reducer and special reducer. The design, manufacturing and use characteristics of the two are different.
