Abstract

PURPOSE:To shorten the occupation length of a joint part by fixing a sleeve having an internal gear to the end of a motor shaft, providing a cylindrical shaft fitted at its periphery with a pinion of a speed reduction device and at the bore with another internal gear, and coupling the two by an internal shaft which has coupler gears at both ends. CONSTITUTION:A sleeve 25 having an internal gear 26 at its bore is fixed to the end of a motor shaft 10, and a cylindrical shaft 29 is provided whose periphery is fitted with a pinion for a speed reduction device and whose bore with another internal gear. An intermediate shaft 27 is equipped with coupler gears 28 at both ends to mesh with the two internal gears 26, 31, and thus the power of this motor shaft 10 is transmitted to the speed reduction device. This should shorten the occupation length of the joint part to lead to increase of the shafting length of the drive motor, increase of the capacity, and reduction of the risk of vibration generations at the coupler owing to lightweight construction.
