Miniature motor with a worm reduction gear |
摘要 |
A miniature motor with a worm reduction gear comprising a miniature motor having a motor shaft, which is of a relatively small diameter and which is extended to a predetermined length, at least three bearings supporting the motor shaft, and a worm having a shaft hole into which the motor shaft is inserted. Since the miniature motor and the worm reduction gear are manufactured separately, and subsequently assembled together by press-fitting the motor shaft in to the shaft hole of the worm the assembly of the miniature motor with a worm reduction gear is facilitated. The use of a motor shaft having a diameter smaller than the diameter of the worm helps reduce the size and weight of the miniature motor with a worm reduction gear.
