Abstract: A planetary gear type reduction gear with torque limiter including an input shaft (7) of an output shaft of a DC motor and an output shaft (14) are journalized on a stationary member (11). At least one stage of the planetary gear type reduction mechanism includes a central gear (8), a planetary gear (34) meshed with the central gear (8), an inner gear (22) meshed with the planetary gear (34), and a carrier (30) journalizing the planetary gear (34). The inner gear (22) is disposed with a clearance to the stationary member 11 in a radial direction, and the inner gear (22) is opposed and disposed to the stationary member (11) in the axial direction by means of friction members (26, 28), which are urged against the inner gear (22). The inner gear 22 is retained at the side of the stationary member (11) in a slip rotation condition by the friction force between the friction members (26, 28) and the inner gear (22).

Abstract: An object of the present invention is to provide a planetary gear type reduction gear with torque limiter that demonstrates always stably torque limiter function, and the invention is characterized in that an input shaft and an output shaft 7 consisting of an output shaft of a DC motor and an output shaft 14 are journalized on a stationary member 11, and at least one stage of the planetary gear type reduction mechanism comprising a central gear 8, a planetary gear 34 meshed with the central gear 8, an inner gear 22 meshed with the planetary gear 34, and a carrier 30 journalizing the planetary gear 34 and a torque limiter are provided between the input shaft and the output shaft.

Abstract: The provision of a one-way clutch having a high strength and a small size and manufactured significantly readily. The one-way clutch includes a casing for supporting a rotating shaft, and a clutch mechanism provided inside the casing. The clutch mechanism allows the shaft inserted in the casing to slide in the casing when the shaft is rotated in one direction and locks the sliding of the shaft when the shaft is rotated in the other direction. The casing 22 include a laminate of a bottom plate member 23a and a plurality of intermediate plate members 23b. Each of the plate members has a press-fit recess 31 extending on one surface, and a press-fit height 32 which extends on the other surface and is press-fitted into a corresponding press-fit recess 31 of an adjacent plate member.

Abstract: A flanged ball bearing has an inner race, an outer race made of sheet steel which is disposed around the inner race with an annular space defined therebetween, and a plurality of balls disposed in the annular space. The outer race has a flange extending radially outwardly. The inner race has a ball groove defined in an outer circumferential surface thereof. The outer race comprises a first annular member and a second annular member which are joined to each other. The first annular member has a first ball guide surface having an arcuate cross-sectional shape. The second annular member has a second ball guide surface having an arcuate cross-sectional shape. Each of the balls is rollingly supported by the first ball guide surface, the second ball guide surface, and the surface of the ball groove.
