A power unit is provided that reduces the frictional resistance between a clutch and a rotary shaft while at the same time prevents an increase in the size thereof. The power unit includes an oil catch member (39) having an inner circumferential surface (39a) positioned radially outward of a rotary shaft (21) relative to an outer circumferential surface (21a) of the rotary shaft (21) and spaced apart from the outer circumferential surface (21a). At least a portion of the oil catch member (39) is disposed between a bearing (34) and a first clutch member (25). An oil reservoir space (45) for storing oil is formed between the inner circumferential surface (39a) of the oil catch member (39) and the outer circumferential surface (21a) of the rotary shaft (21), the oil reservoir space (45) being in communication with a clearance gap (37) between the outer circumferential surface (21a) of the rotary shaft (21) and an inner circumferential surface (36a) of a bore (36) of the first clutch member (25).
摘要:
A wave generator (5) for a strain wave gearing (1) makes a flexible externally toothed gear (4) to flex into an elliptical shape and mesh with rigid internally toothed gears (2, 3), and makes meshing positions of the flexible externally toothed gear with the both gears (2, 3) to move in a circumferential direction. On the inner side of a rigid plug (6) of the wave generator (5), a plug support ring (11) is secured and integrated. The rigid plug (6) is formed from an iron-based material, and the plug support ring (11) is formed from a high-rigidity material that is more rigid than the iron-based material. Since deformation of the rigid plug (6) is suppressed, the wave generator (5) provided with a large hollow part (9) can be obtained.

A mobile electronic device fixing module includes a mobile electronic device and a base. The mobile electronic device includes an assembling interface and a first transmission terminal group. A ring-shaped groove is formed in the assembling interface. The base is assembled with the assembling interface. The base includes plural rotary fixing slices and a second transmission terminal group. The second transmission terminal group corresponds to the first transmission terminal group. When the base is assembled with the assembling interface and the plural rotary fixing slices are rotated, the plural rotary fixing slices are inserted into the ring-shaped groove to be in a locked state, or the plural rotary fixing slices are removed from the ring-shaped groove to be in an unlocked state. When the base is assembled with the assembling interface, the second transmission terminal group is electrically connected with the first transmission terminal group.

According to the present invention, there is provided a gear comprising teeth formed on the outer circumference of the gear and a central hole formed at the center of the gear; an intermediate region between a peripheral portion near the teeth and a boss near the central hole formed to have a thickness thinner than those of the peripheral portion and the boss; a plurality of weight-lightening apertures formed circumferentially and equidistantly in the intermediate region; and a vibration absorbing member of synthetic rubber formed on both side surfaces of the intermediate region integrally each other through the weight-lightening apertures, the vibration absorbing member is attached to the radially outer side than an outer diameter of a bearing to be arranged adjacent to the vibration absorbing member. According to the present invention, there is also provided an electric actuator comprising an electric motor mounted on a housing; a speed reduction mechanism for transmitting rotational force of the motor to a ball screw mechanism; and the ball screw mechanism being able to convert the rotational motion of the electric motor to the axial linear motion of a driving shaft and comprising a nut and a screw shaft; the nut being formed with a helical screw groove on its inner circumference, securing on its outer circumference an output gear forming part of the speed reduction mechanism and the screw shaft being formed on its outer circumference with a helical screw groove corresponding to the helical screw groove of the nut, adapted to be inserted into the nut via a large number of balls, and supported not rotationally but axially movably relative to the housing characterized in that the output gear is secured on the outer circumference of the nut with being sandwiched by an inner ring of one supporting bearing and a flange portion of the nut, and that the output gear is configured by a gear defined in any one of claims 1 to 5.
