    Abstract: A reverse-input blocking clutch, comprising a pressed member, an input member, an output member, and an engaging element, the pressed member including a first pressed member element having a pressed surface around an inner peripheral surface thereof and a second pressed member element having a mounting portion fixed to a portion that does not rotate during use, the engaging element configured to transmit rotational torque input to the input member to the output member by moving in a direction away from the pressed surface and to completely block rotational torque reversely input to the output member or transmit a part of the rotational torque reversely input to the output member to the input member and block a remaining part thereof.

    Abstract: A mechanical backstop is provided which comprises a housing, an input impact gear, a frictional plate, a floating impact gear, and an output impact gear. The floating impact gear is movably mounted between the input impact gear and the output impact gear to achieve transmission. The frictional plate is fixed relative to the housing and disposed at a side of the floating impact gear close to the input impact gear. When the input impact gear transmits a torque to the floating impact gear, the floating impact gear floats toward the output impact gear to separate from the frictional plate and transmit the torque to the output impact gear. When the floating impact gear transmits a torque reversely, the floating impact gear floats toward the input impact gear to abut against the frictional plate and achieve reverse locking.

    Abstract: Provided is a clutch unit in which an output-side outer ring member is attached to a base plate without welding. A clutch unit (100) includes an output-side clutch (60) and a housing (11) that accommodates the output-side clutch (60). The output-side clutch (60) includes an output-side outer ring member (62). The output-side outer ring member (62) and the housing (11) have an engagement protrusion (62s) and an engagement groove (11s) that engage with each other to restrict relative rotation therebetween.

    Abstract: An example rotational joint assembly for a robotic medical system, the rotational joint assembly comprising at least one arm segment and a rotational joint provided at one end of the arm segment. The rotational joint is to allow the arm segment to rotate about a rotational axis. The rotational joint comprising a brake to lock rotation of the arm segment at the rotational joint and an actuator to selectively engage or disengage the brake. The actuator comprising a cam having two stable regions separated by two transition regions, the two stable regions comprising a first stable region corresponding to engagement of the brake and a second stable region corresponding to disengagement of the brake.

    CPC classification number: B60B9/28 B60B9/18 F16D67/02

    Abstract: A wheel structure includes a variable spoke configured to connect a wheel and a central shaft and having a length that varies in a radial direction of the wheel, a spoke driving unit configured to provide power for changing the length of the variable spoke in the radial direction, and a power transmission unit configured to transmit power from the spoke driving unit to the variable spoke. A plurality of variable spokes are spaced apart from one another in the circumferential direction. The power transmission unit includes an output shaft configured to rotate by receiving power from the spoke driving unit, and a clutch configured to connect the variable spoke and the output shaft and selectively transmit a rotational force of the output shaft to the variable spoke or cut off the transmission of the rotational force to the variable spoke.

    Abstract: An adjustment device for adjusting seats includes a rotatable drive element, a rotatable output element, a first clamping element freewheel that blocks the output element continuously in different positions in both adjustment directions and that is released by a release element and a second clamping element freewheel that is coupled via the release element to the first clamping element freewheel, blocks the output element continuously in different positions in both adjustment directions and is released by an actuating element. The drive element is pre-tensioned in a middle position via two springs acting in different directions and the two springs pre-tension the actuating element in a middle position.
