Abstract: According to the characteristics of mini planetary reducer, the main causes affecting the lost motion of mini planetary reducer were analyzed. Taking a φ8 mm planetary reducer as an example, controlling the backlash between the gear pair, and the fit clearance between the planet gear and planetary pin, coupled with method of grading assembly, the lost motion of reducer was controlled.

Key words: mini planetary reducer, lost motion, grading assembly
