Abstract

PURPOSE: To enable the ratio of speed reduction through only the exchange of the first stage gear, by placing the axis of a motor pinion uncoincidently to the center of a gear case socket-and-spigot fitting means provided in an electric motor.
CONSTITUTION: In application to a one-step speed reducer for an electric motor, the first stage gear is removably secured on an output shaft 5 so that the gear is engaged with a motor pinion 2. A gear case 4 and a motor bracket 3 are fitted on each other by a socket-and-spigot fitting means and positioned by a knocked-in pin. The axis 16 of a motor spindle and the center 14 of the fitting means are placed at a distance of (e) from each other. The axis 15 of the gear 9 and the center 14 of the fitting means are placed at a distance of (c) from each other. The distance of (a) between the axes of the pinion 2 and the gear 9 varies according as the gear case 4 is rotated along the fitting means. For that reason, the case 4 is rotated to move the pin 6 to positions AWC to engage the pinion 2 with the prescribed gear 9. The ratio of speed reduction can thus be changed.
