ギアードモータ
Document Type and Number:
Japanese Patent JP6625658
Kind Code:
B2
Abstract:
Provided is a geared motor with which a large torque can be obtained without an increase in size. In this geared motor (1), an output member (8) having a helical groove (83) formed in an outer circumferential section is provided between a first plate part (31) and a second plate part (32) of a frame (3), and the rotation of a motor pinion (55) fixed to a rotary shaft (50) is reduced in speed by transmission gears of a reduction gear mechanism (9) and is transmitted to a gear part (85) of the output member (8). Thus, a large torque can be output, even when the gear part (85) of the output member (8) is made smaller than the outer diameter of the section (84) provided with the helical groove (83). Also, even when a gear cover (7) is provided, a lateral plate part (72) of the gear cover (7) covering the outer circumferential section of the gear part (85) of the output member (8) is located close to the rotation center axis of the output member (8). Thus, it is possible to prevent the geared motor (1)from being increased in size by the gear cover (7).
