SPEED REDUCTION MECHANISM OF GEARED MOTOR

摘要

PURPOSE:To contrive to simplify the gear mechanism, to form in a small type and to reduce weight of the speed reduction mechanism of the geared motor by a method wherein an outside gear formed at the tip of a motor shaft protruded from a motor main body case is made to gear into an inside gear formed at the inside edge of an output shaft supported enabling rotation by a motor cover. CONSTITUTION:The outside gear 3 is formed on the outside circumference of the tip of the motor shaft 1 protruded from the motor main body case 2, while a bearing 6 is provided at the supporting part 5 of a left side motor cover 4 fixedly coupled to the main body case 2, and the motor shaft 1 is supported enabling rotation. Moreover a pair of bearing metals 10 are provided in a pair of semicircular arc type bearing supporting parts 9 provided facing to the supporting part 5 of the left side motor cover 4, an inside gear 11 is engaged floating impossibly with the inside circumferential face of the bearing metals 10 thereof to make the inside gear 11 and the outside gear 3 to gear into mutually, while the output shaft 13 protruded being formed in one body from the inside gear 11 is supported by two bearings 16, 17 provided inside of the bearing supporting part 14a of a right side motor cover 14.
