摘要： A pump includes a stator and a rotor axially between a fluid inlet section and a fluid outlet section. The stator includes a plurality of radially inwardly extending legs; and a plurality of electrical windings disposed about the radially inwardly extending legs. The attenuating circuit includes a capacitor electrically wired in parallel with each winding and at least one switch electrically connected to the capacitor. During energization of the electrical winding, the switch electrically connects the capacitor to an electrical ground and the electrical power source creates a voltage in the capacitor. Following a de-energization of the plurality of electrical windings, the switch isolates the capacitor from the electrical ground and the capacitor discharges the voltage through the electrical winding, creating a decaying oscillating current that attenuates residual magnetization in the winding.

摘要： A hand-propelled, self-driving, traveling machine that includes a clutch which enables transmission between a wheel and a transmission shaft. The clutch provides a drive state in which the transmission shaft drives the wheel to rotate and an unlocked state in which the wheel is rotatable relative to the transmission shaft. The clutch includes a driving member, combined with the transmission shaft, a movable pin, movable between a locked position in which the clutch is in the drive state and an unlocked position in which the clutch is in the unlocked state, a transmission member connected to the wheel, a movable friction member provided with a limiting slot, where the movable pin is partially disposed in the limiting slot, and a fixed friction member that is fixed to the chassis and that is in a frictional contact with the movable friction member.

摘要： A clutch unit includes a lever-side clutch section configured to control transmission and interruption of rotational torque input by a rotation of an operation lever, and a brake-side clutch section configured to transmit the rotational torque from the lever-side clutch section to an output side and interrupt rotational torque that is reversely input from the output side. The lever-side clutch section includes a side plate to which the operation lever is fixed and an outer ring member that fits with the side plate. The brake-side clutch section includes a cover whose rotation is restricted. An angle regulating part configured to regulate a rotation angle of the operation lever is disposed radially inside of outer peripheral edges of the outer ring member and the cover and includes a claw of the outer ring member and a through hole of the cover.

摘要： An object of the present invention is to provide a cam clutch capable of switching from one operating mode to another with a simple structure and with high responsiveness, and of securing an expected torque capacity. The cam clutch of the present invention includes an operating mode switch mechanism (140) for switching between a free state that allows relative rotation between an inner race (110) and an outer race (120) and a locked state that prohibits relative rotation between the inner race (110) and the outer race (120). The operating mode switch mechanism (140) includes a cam attitude change part (142) that is movable circumferentially, radially, or axially independently of the rotation of the inner race (110) and the outer race (120) to forcibly tilts a plurality of cams (131) circumferentially arranged between the inner race (110) and the outer race (120).

摘要： The current document is directed to a two-way, by-passable, overrunning clutch incorporated within a mechanical prosthetic knee that provides functionality similar to a biological knee or incorporated in another articulated device, such as a robotic or orthotic articulated device or member. The currently disclosed two-way, by-passable, overrunning clutch allows for two-way free rotation when disabled, but, when enabled, prevents rotation in one direction while allowing free rotation in the other direction. In the mechanical prosthetic knee, the two-way, by-passable, overrunning clutch is enabled by application of a mechanical force and disabled by removal of the mechanical force.

摘要： A backrest recline mechanism including a first shaft attachable to a first seat assembly component and a second shaft attachable to a second seat assembly component. The first shaft has a slotted ring defining capture slots and an interior annular space. A control ring has a first end disposed in the annular space. The second shaft is engaged with a second end of the control ring. A first collar, having a plurality of release recesses, is rotatably disposed around the slotted ring. First bearings respectively retained within the capture slots are beneath the first collar. In a first rotational position of the first collar, the plurality of release recesses align with the capture slots to rotationally disengage the first and second components. In a second rotational position, the release recesses misalign with the capture slots to rotationally engage the first and second seat assembly components.

摘要： This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.

摘要： A switchable ratcheting clutch achieves four different modes of operation based on a relative rotational position of a cam ring and an inner ring. In a central relative position, an outer ring can rotate freely in either direction with respect to the inner ring. In either extreme relative position, the outer ring is prevented from rotating in either direction relative to the inner ring. In intermediate positions one either side of the central position, the outer ring is permitted to rotate in one direction but not the other. A number of pawls are supported on the inner ring and pushed radially out of engagement with the outer ring by a spring on a spring cage. The spring cage moves with the cam ring between the one-way positions but the cam ring rotates relative to the spring cage when moving into the extreme positions.

摘要： A clutch, including: an inner race forming a pocket; an outer race; a pawl including a portion in the pocket; and a cage radially disposed between the inner race and the outer race. The cage includes a radially outer surface segment and a lift off bump stop extending from the surface segment. For a one-way mode, the inner race rotates, with respect to the outer race, only in one circumferential direction. For a first phase of the one-way mode, the inner race rotates in the circumferential direction and the pawl is arranged to be in contact with the outer race and free of contact with the lift off bump stop. For a second phase of the one-way mode: the inner TO race rotates in the first circumferential direction; and the pawl is arranged to be in contact with the lift off bump stop and free of contact with the outer race.

摘要： A rotation transmission device is provided which includes, in its housing, an electromagnetic clutch, and a two-way clutch by which a first shaft and a second shaft are selectively engaged with, and disengaged from, each other. A rolling bearing is disposed at one axial end of the housing, and supports the second shaft and the housing. Locking arrangements prevent relative axial movement between the second shaft and the rolling bearing, and between the rolling bearing and the housing. A movement restricting arrangement is disposed at the other axial end of the housing, and restricting movement of the electromagnetic clutch toward the other axial end of the housing.
