A decoupler assembly for disengaging a shaft transmitting torque between a rotatory engine and an electric generator. The decoupler assembly includes an output shaft, input shaft wherein the output shaft is selectively coupled to the input shaft. Retractable balls are incorporated into the assembly in order to couple and decouple the input shaft from the output shaft.

An end effector includes a drive system to rotatably drive a removeable cutting accessory. The cutting accessory defines a bore. The drive system includes a drive member that defines a lumen. A cartridge is provided to deliver liquid from a liquid source, through the lumen of the drive member, through the bore of the cutting accessory, and to a surgical site.

A clutched component having a locking mechanism that employs a plurality of radially movable locking elements to selectively rotationally couple first and second coupling parts to one another. A sleeve is employed to control radial movement of the locking elements.

A wedge clutch includes an inner race and an outer race. The outer race defines an inner cam surface. A chain of wedges encircles the inner race and are configured to couple the races when the clutch is engaged. The wedges have outer surfaces that match with sections of the inner cam surface such that the wedges have an outer radial position when in first rotational position relative to the cam surface and have an inner radial position when in a second rotational position to frictionally engage the inner race.

A wedge clutch includes an inner race and an outer race circumscribing the inner race. A wedge element is radially disposed between the inner and outer races and actuatable to couple and decouple the inner and outer races. An actuator is operably coupled with the wedge element and is configured to actuate the wedge element to decouple the inner and outer races.

A self-contained switchable wedge plate clutch, consisting of: a housing arranged to receive rotational torque; and a clutch assembly. The clutch assembly includes: an outer race non-rotatably connected to the housing; an output hub; a plurality of circumferentially aligned wedge plate segments, enclosed by the housing, radially disposed about the output hub; and an activation assembly at least a portion of which is enclosed by the housing. The activation assembly is arranged to displace the plurality of circumferentially aligned wedge plate segments to switch the self-contained switchable wedge plate clutch between: a locked mode for the sell-contained switchable wedge plate clutch, in which the housing and the output hub are non-rotatably connected; and an unlocked mode for the self-contained switchable wedge plate clutch, in which the housing and the output hub are rotatable with respect to each other.

A clutch mechanism is used in a rotary power tool having a motor. The clutch mechanism includes an input member to which torque from the motor is transferred and an output member co-rotatable with the input member. The output member defines a rotational axis. A cam surface is formed on one of the input member or the output member. First and second compression springs are carried by the other of the input member or the output member for co-rotation therewith. A follower has a circular cross-sectional shape and is biased against the cam surface by the first and second compression springs. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with each of the first and second compression springs. The line of action does not intersect the rotational axis.
