ABSTRACT:
A motor with a decelerating apparatus includes a motor, a gear box connected to the motor, a pinion gear attached to an end of an output shaft of the motor, two or more decelerating gears engaging with the pinion gear, a rotation shaft connected to each of the decelerating gears as a unity, a bearing for supporting the rotation shaft of each of the decelerating gears provided in the gear box, and a mounting unit for fixing the gear box to a load, an output terminal of the rotation shaft of each of the decelerating gears being connected to a rotating load, the gear box comprising a bearing for supporting a rotation shaft of a first decelerating gear which engages with the pinion gear and a bearing for supporting a rotation shaft of a second decelerating gear which engages with the pinion gear and is different from the first decelerating gear in the number of teeth, the mounting unit connecting the output terminal of the rotation shaft of either of the first and second decelerating gears to the rotating load, and the gear box selectively having either of the first and second decelerating gears to vary a decelerating rate.
