A system for driving a reel mixing tool, including a unit structure, a bottom output shaft, an output gearbox, a reel mixer driveshaft, a reel mixer gearbox, a flexible coupling, and a reel mixing tool, is provided. The unit structure supports the bottom output shaft which is connected to the output gearbox, the output gearbox is connected to the reel mixer driveshaft, the reel mixer driveshaft is connected to the reel mixer gearbox, the reel mixer gearbox is directly coupled to the reel mixing tool by the flexible coupling, allowing the bottom output shaft to transfer power through to the reel mixing tool.

The engine starter includes a pinion-mobile component which is linked to an output shaft by a helical spline and can be slid in a shaft direction, in a state where the pinion-mobile component includes; an overrunning clutch which is idled when the pinion gear, which is engaged to the ring gear, is driven by the engine via the ring gear so as to be rotated at a rotational speed which is higher than a rotational speed of the output shaft; and a breaking mechanism in which the overrunning clutch breaks a transmission of a torque, which is generated in accordance with a rotation of the motor and is transmitted to the ring gear, when a value of the torque is a predetermined condition value with respect to a direction where the torque is transmitted to the ring gear.

A tolerance ring for a torque transmission device is arranged in an annular space between an inner shaft member and an outer shaft member. The tolerance ring has a ring-shaped portion and a plurality of protrusions. The ring-shaped portion has a cylindrical shape and is brought into contact with one of the shaft members. The plurality of protrusions undergo elastic deformation and are arranged in a peripheral direction. The ring-shaped portion has seat portions formed between the protrusions that are adjacent to each other in the peripheral direction. The plurality of protrusions include selected protrusions that have the same shape and that are situated at the same axial position and unselected protrusions other than the selected protrusions. The selected protrusions and the unselected protrusions differ from each other in axial position of center point in a length direction.

An enhanced material-processing device and method are disclosed, having a processing tool of substantially circular circumference, which is operative with a power tool having a rotating spindle and jaws, which clamp the processing tool. The enhanced material-processing device has a central opening that is entered concentrically in the processing tool for receiving a clutch mechanism, and a hub structure. The hub structure is associated with the clutch mechanism to form a slip clutch that is integrally mounted in the enhanced material-processing device and is operative by application of an axial compression friction fit on the processing tool, which slips relative to the rotating spindle when a threshold torque limit is reached. The clutch mechanism is preloaded in axial compression through a predetermined elastic strain distance to provide a friction fit having a torque limit threshold, which torque limit of the slip clutch is controllably pre-adjustable.

A damper device includes a first member, a second member, an elastic member and a supporting member. The first member has two wall members separated from each other. The supporting member includes projections (preventing portion) that make contact with one of two wall portions (wall members) so as to prevent the supporting member and an elastic member from being inclined (falling, rotationally moving) in the axial direction.

A torque limiter fixed to a flywheel including an annular portion and an accommodation portion is disclosed. The torque limiter includes a first plate, a second plate axially opposed to the first plate, a friction disc disposed between the first and second plates, a pressing member, and a third plate. A torque is inputted to the first plate. The pressing member presses the second plate onto the friction disc. The third plate supports the pressing member with the second plate therebetween while the pressing member is compressed. The third plate includes a support portion supporting the pressing member and a tubular portion provided in an outer peripheral part of the support portion. The tubular portion covers an outer peripheral surface of the friction disc. The tubular portion axially extends and is opposed to an inner peripheral surface of the annular portion of the flywheel, and includes first openings circumferentially aligned.

A return stop device with a freewheel having an internal ring, an external ring, and retaining elements arranged in an annular gap therebetween. A flange is provided at the attachment side and a housing part, between which the external ring is clamped, and a clamping device by which the external ring is pressed with its face between the flange and the housing part against a friction area, in order to generate a friction-fitting connection between the flange and the external ring. A release device is provided to at least partially overcome the contact pressure, in order to reduce or remove the friction-fitting connection. The release device includes an actuating organ, which acts upon a first gliding element, displaceable in an operating direction, to act upon a second gliding element, arranged displaceable perpendicular to the operating direction, that acts via a second wedge against the contact pressure upon the housing part.

An accessory drive tuning device with a torsion spring for angular vibration isolation and having a spring pocket that frictionally engages the end of the torsion spring. The engagement may be with a wedge-shape on either the spring end or the pocket or both, adapted so that the spring end wedges into the pocket. The engagement may be by interference fit. One or both ends of the spring may be engaged in respective pockets.

An isolating decoupler comprising a shaft, a pulley journalled to the shaft, a torsion spring, the torsion spring comprising a flat surface planar in a plane normal to the rotation axis A-A on each end of the torsion spring, a one-way clutch engaged between the torsion spring and the shaft, a weld bead joining a torsion spring end to the one-way clutch, and a weld bead joining the other torsion spring end to the pulley.

In an aspect, a power transfer device, such as a decoupler, is provided for transferring torque between a shaft and a belt. The device includes: a hub configured to 5 couple to the shaft, a pulley rotatably coupled to the hub that includes a power transmitting surface configured to engage the belt, an isolation spring to transfer a rotational load from one of the pulley and the hub to the other of the pulley and the hub, optionally a one-way clutch to permit overrunning of one of the pulley and the hub relative to the other of the pulley and the hub in a first direction, and a damping member 10 positioned to be driven into frictional engagement with a friction surface by a force from the isolation spring acting on the damping member that varies based on the rotational load transferred by the isolation spring.
