Technical Field

[0001] The utility model relates to the technical field of gear reducers, in particular to a gear reducer with adjustable output direction. Background Art

[0002] Planetary gear reducers are also called planetary reducers and servo reducers. Planetary reducers are widely used in transmission systems such as servo motors, stepper motors, and DC motors due to their small size, high transmission efficiency, wide reduction range, and high precision.
