A one-way clutch, including: a load rotor, a driving member, and at least one self-locking gripper. The load rotor is spool-shaped and includes two circular contact races, one race at each end of the rotor. The driving member includes a plurality of inward facing cams on an inner circumference arranged to rotate co-axially with the load rotor. The cams rotate within the space separating the two load rotor races. When in a locking position each gripper presses against both load rotor races and a cam over area-to-area contacting surfaces. Rotation of the load rotor and driving member are locked in the first direction when one or more grippers are in the locking position. The driving member is rotatable independent of the load rotor in the second, free-wheeling direction. During free-wheeling rotation centrifugal force acts to disengage the grippers from the load rotor, thus reducing or eliminating friction.

The present disclosure discloses one example of a one-way coupling that eliminates the need for a component corresponding to a guide piece. The one-way coupling of the present discloser includes an input shaft and an output shaft, and is configured to transmit a drive force from the input shaft to the output shaft, and inhibit the drive force inputted to the output shaft from being transmitted to the input shaft. The one-way coupling includes: a transmitter; an immovable ring; a pressure-contact cam; a first wedge member displaceable between a locked position and an unlocked position, and receiving a pressing force from the pressure-contact cam when the drive force is inputted to the input shaft, and thereby the first wedge member is displaced to the locked position; and a first holder holding an arrangement of the first wedge member when the drive force is inputted to the output shaft.

Disclosed is a continuously variable transmission which can simplify a structure and contribute to miniaturization of a device. A continuously variable transmission including a first disk unit with a first guide slot, a second disk unit with a second guide slot which the first guide slot crosses, and a guide member provided to move along the first guide slot and the second guide slot in response to relative rotation of the second disk unit to the first disk unit, includes: a rotation driving unit rotating any one of the first disk unit and the second disk unit with respect to the other one, wherein the rotation driving unit includes a barrel cam member, a linear movement member linearly moving in response to rotation of the barrel cam member, a driving cam member linearly moving together with the linear movement member, and a driven cam member rotatably connected integrally with any one of the first disk unit and the second disk unit and selectively rotating in response to the linear movement of the driving cam member.

A wedge friction clutch with onboard enable and disable function, including: an axis of rotation; an inner race; an outer race; a wedge plate located between the inner and outer races in a radial direction; a first resilient element; and a piston. For a locked mode, the first resilient element is arranged to displace the wedge plate in a first circumferential direction to non-rotatably connect the inner and outer races. For a free wheel mode the piston is arranged to displace in a first radial direction to displace the wedge plate in a second circumferential direction, opposite the first circumferential direction such that the inner and outer races are independently rotatable with respect to each other.

Aspects of the disclosure relate to a clutch assembly (100) for handling a container, and an associated method for using the clutch assembly. The clutch assembly includes a shaft (102) configured to rotate in a first direction and a second direction, opposite from the first direction. The clutch assembly further includes a clutch coupled to a first end of the shaft. The clutch includes at least two rollers (108) configured to move into a first position, extending radially beyond a periphery of the clutch, and out of the first position, extending radially flush with or inward from the periphery of the clutch.

A one-way clutch, including: an inner race including a first outer circumference with a first plurality of ramps and at least one wedge plate including: a first inner circumference with a second plurality of ramps; a second outer circumference; and a first plurality of slots: passing through material forming the at least one wedge plate in an axial direction; including respective first ends open to the second outer circumference; and including respective second ends radially outward of the first inner circumference and enclosed by the at least one wedge plate. The one-way clutch includes an outer race including a second inner circumference. The outer race is able to rotate with respect to the inner race in a first circumferential direction. Rotation of the outer race in a second circumferential direction, opposite the first circumferential direction, causes the rotation of the outer race to lock to rotation of the inner race.
