摘要： A power transmission device includes a first one-way clutch that transmits a rotational power of a pulley to a rotating shaft, and a second one-way clutch that transmits a rotational power of a rotor of a motor to the rotating shaft. The first one-way clutch is of inner cam type in which an engagement cam-surface is formed in an outer periphery of a first inner ring, while the second one-way clutch is of outer cam type in which an engagement cam-surface is formed in an inner periphery of a second outer ring. This arrangement improves engagement performance of the first one-way clutch as well as reducing heat generation of the second one-way clutch, so that the lifetime of grease is prolonged.

摘要： There is provided a compact one-way clutch unit that can perform connection and disconnection of power in two systems. An end portion on a side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in an annular recess 67, which is provided at an end portion in an inner peripheral surface of a first inner ring 7, so that the dimension in an axial direction of a one-way clutch unit is reduced. Further, an outer peripheral diameter on a side of the deep groove ball bearing portion 65 is made smaller than that on the side of a one-way clutch portion 60 of a second outer ring 14 so as to reduce a diameter of the recess 67 and the outer peripheral diameter of the first outer ring 5 of the first one-way clutch 1.

摘要： In this driving force transmission apparatus, with a simple constitution employing a one-way clutch 20 instead of an electromagnetic clutch, the driving force derived from the motor 33 can be transmitted to the rotating shaft 1 during engine stops, and the driving force of the engine can be transmitted to the rotating shaft 1 during engine operations. Also, the pulley 3 is held against the connecting portion 11 and the fixed-side member 26 by means of first and second two ball bearings 21, 30 disposed axially adjacent to first and second inner cylinder portions 6, 7, respectively, between which the opening portion 5 of the pulley 2 is interposed. This simple driving force transmission apparatus can switch between transmission and non-transmission of driving force from pulley to rotating shaft, and transmits the driving force of a motor directly to the rotating shaft in the non-transmission state.

摘要： A pulley unit includes a pulley and a rotor concentrically disposed for relative rotation, a one-way clutch interposed in an annular space therebetween, rolling bearings provided on opposite sides of the one-way clutch, and a seal ring for sealing the annular space. An inner diametrical surface of the pulley forms an outer ring raceway of the one-way clutch and the rolling bearing, and an outer diametrical surface of the shaft body forms an inner ring raceway of the one-way clutch and the rolling bearing. An outer diameter side of an annular portion of a retainer of the rolling bearing on the side of the seal ring is reduced so as to increase a storage volume of lubricating oil between the rolling bearing and the seal ring.

摘要： A pulley is concentrically disposed around a hollow shaft, and a one-way clutch is disposed between the hollow shaft and the pulley. At least one bearing is provided between the shaft and the pulley. In the one-way clutch, a roller as a meshing member and a coil spring as a biasing member are integrally rotated together with an outer ring. The roller moves in a meshing-releasing direction by a centrifugal force when a rotation speed of the outer ring becomes equal to or higher than a predetermined speed, and a biasing force of the coil spring has enough magnitude for permitting this movement. The pulley is provided at its inner periphery with a cam surface, and the pulley and the outer ring of the one-way clutch are integrally formed.

摘要： A rotation adjusting mechanism is provided in a power transmission path from a pulley to a rotation shaft and includes an elastic member and a clutch mechanism. The elastic member reduces a minute change in rotation generated in at least one of the pulley and the rotating shaft by its elastic deformation. The clutch mechanism is provided in an intermediate position of the power transmission path from the elastic member to the rotating shaft and configured to interrupt the power transmission from the pulley to the rotating shaft when a rotation speed of the pulley lowers below a rotation speed of the rotating shaft by a predetermined value or greater.
