摘要： A clutch includes: a rotor that has a steel material as a base material and is rotated upon receiving a rotational drive force from a drive source; and an armature that has a steel material as a base material and receives the rotational drive force from the rotor when the armature is attracted to the rotor by a magnetic force. The armature has a contact surface side region that includes a contact surface, which contacts a counterpart when the armature is attracted to the rotor. The contact surface side region has a plurality of pores opened at the contact surface and forms a nitride compound of an element of the base material through nitridization of a part of the base material while the contact surface side region is harder than an unreacted portion of the base material that is not reacted at the nitridization.

摘要： An inner peripheral surface of an outer cylindrical tubular portion and an outer peripheral surface of an inner cylindrical tubular portion of a rotor are respectively shaped into a stepped form. A radial distance between the outer cylindrical tubular portion and the inner cylindrical tubular portion at a counter-armature side location is larger than that of an armature side location in the rotor. An outer peripheral surface of an outer cylindrical tubular portion and an inner peripheral surface of an inner cylindrical tubular portion of a stator are respectively shaped into a stepped form. A radial distance between the outer peripheral surface of the outer cylindrical tubular portion and the inner peripheral surface of the inner cylindrical tubular portion at the counter-armature side location is larger than that of the armature side location in the stator.

摘要： An adaptor is disclosed for connecting a generator to a prime mover. The adaptor comprises two separable parts. By providing an adaptor comprising two separable parts, it may be possible for one part to be removed in order to allow access to moving parts which would otherwise be inaccessible. This may simplify the process of servicing moving parts such as a coupling or bearings, without requiring the generator and the prime mover to be moved apart. A coupling with a radially removable elastomeric component is also disclosed.

摘要： A rotary elastic coupling is fitted with an inner ring and with an outer ring surrounding the inner ring around the periphery by forming an annular slit. An elastomer is provided in the annular slit, which is vulcanized or glued to the inner ring and to the outer ring and fills up the annular slit substantially or completely. The annular slit is meander-shaped around the periphery of the coupling so that radially outward protrusions of the inner ring undercut radially inward protrusions of the outer ring. Around the periphery of the coupling, a relief opening is provided in the elastomer on both sides of the protrusions of the inner ring and on both sides of the protrusions of the outer ring.

摘要： A one-way clutch is proposed which includes an outer race having a radially inner surface in which a plurality of pockets are formed. Rollers are each received in one of the pockets. Wedge-shaped spaces are defined between respective cam surfaces of the pockets and a shaft inserted through the outer race. When the shaft rotates in one direction, the rollers are wedged into the narrow ends of the respective wedge-shaped spaces, thereby locking the clutch. When the shaft rotates in the opposite direction, the rollers move toward the wide ends of the wedge-shaped spaces, thereby unlocking the clutch. The casing includes a main body and a cylindrical member fitted in the main body and made of an elastic synthetic resin. The outer race is fitted in the cylindrical member.

摘要： A power transmission apparatus comprising a pulley 1 and a hub 2 is disclosed. The hub 2 includes an inner hub 21 fixed on a rotary shaft 4 and an elastic member 23 coupled over a joint length L to the outer periphery of the inner hub 21. Elastic member 23 includes a hub-side engaging portion having a series of protrusions arranged in a ring and a cylindrical portion connecting the hub-side engaging portion and the inner hub. Pulley 1 has a pulley-side engaging portion having a series of depressions fitted on the hub-side engaging portion. The engagement between hub-side engaging portion 235 and pulley-side engaging portion 14 forms a torque transmission structure of hub 2 and pulley 1. An axial length TL of a torque transmission surface TS formed by hub-side engaging portion 235 and pulley-side engaging portion 14 in contact with each other is larger than joint length L between the cylindrical portion and inner hub 21. Axial length TL, when projected in the radial direction, is partially overlapped with joint length L.
