摘要： An electromagnetic clutch is provide that includes a fixed component, a driven component and an elastic component. The fixed component includes a magnetic yoke provided thereon with multiple iron cores, and each iron core is provided thereon with a coil. The driven component includes an armature disc provided thereon with multiple magnets. The armature disc and the magnetic yoke are disposed correspondingly, and the iron cores and the magnets are disposed correspondingly. The elastic component is used to keep the armature disc at a disengaged position from magnetic yoke. When the coil is energized in a forward direction, the iron core attracts the magnet and when the coil is energized in a reverse direction, the iron core generates an electromagnetic force to reduce an attractive force of the magnet.

摘要： An interrupter includes: an intermittent member having a meshing tooth meshing with a second rotary member, and moving in an axial direction between a coupled position and an uncoupled position; and an actuator making the intermittent member move in the axial direction. The actuator includes: a coil generating magnetic flux; and a plunger moving with the intermittent member in the axial direction. The plunger is disposed in a manner capable of making relative rotation to one of the first and second rotary members via first and second air gaps. When the coil is energized, the magnetic flux is introduced to the plunger from one of the first and second air gaps, the magnetic flux is led out of the plunger to the other air gap, and the plunger moves in the axial direction so as to reduce at least one air gap of the first and second air gaps.

摘要： A differential apparatus includes a differential mechanism, a differential case that accommodates the differential mechanism, and a clutch mechanism that transmits a driving force between the differential case and the differential mechanism. The clutch mechanism includes a side member movable inside the differential case in an axial direction and an actuator for moving the slide member to the axial direction. The slide member has a first meshable portion at one end in the axial direction, is allowed to move relative the differential mechanism, and is prevented from rotating relative to the differential mechanism. The differential case has a second meshable portion facing the first meshable portion in the axial direction. When the slide member moves toward the second meshable portion by actuation of the actuator the first meshable portion meshes with the second meshable portion so that the differential case and the slide member are coupled to prevent a relative rotation between the differential case and the slide member.

摘要： A clutch module which includes a first rotating member including at least one strut actuation module and a second engaged member including cam surfaces thereon for engagement by said strut actuation module. The strut actuation module includes a frame with a strut pivotally movable with respect to the frame. The strut includes an engagement end and a base end including a first side and a second side thereof. A pin or post portion extends from the frame and has an insulated bobbin with an energizable coil surrounding the bobbin. A U-shaped member including a pair of actuation legs is attached to the pin member and forms a magnetic gap between the base end of the strut and peripheral ends of the legs, such that when the coil is energized the peripheral ends of the legs are polarized in a first polarity and the frame and the strut are polarized with an opposite polarity thereby biasing the strut toward the peripheral ends and pivoting the actuation end into engagement with a cam surface of the engagement member.

摘要： A dog clutch includes: a first rotational member; a second rotational member; a clutch member; and a pressing mechanism. The clutch member includes a meshing portion meshing with the second rotational member, an engageable portion circumferentially engaging with an engaged portion provided in the first rotational member, and a cam surface configured to generate a cam thrust in a direction of a rotation axis by a relative rotation with respect to the first rotational member. When the clutch member moves, a depth of meshing with the second rotational member is deepened by the cam thrust, and then the engageable portion engages with the engaged portion, so that the clutch member receives a torque from the first rotational member.

摘要： Apparatuses and methods are provided for facilitating air-cooling of, for instance, one or more electronics racks within a data center. The apparatus includes an air-moving assembly and an auxiliary turbine drive. The air-moving assembly includes a shaft, one or more mechanical fans coupled to the shaft to rotate, at least in part, with the shaft, and a motor coupled to the shaft to rotatably drive the shaft. The auxiliary turbine drive is coupled to the shaft of the air-moving assembly to provide backup rotational energy to the shaft to facilitate continued rotation of the shaft during interruption in power to the motor. In one implementation, the auxiliary turbine drive is configured to facilitate, for a specified time period, continued rotation of the shaft at a specified percentage, or greater, rotational speed of the shaft compared with a shaft speed when rotatably driven by the motor.

摘要： A clutch apparatus comprises a torque limiter body and a solenoid brake magnet. The torque limiter body is pivotable relative to the solenoid brake magnet when torque acting between the torque limiter body and the solenoid brake magnet is greater than a threshold value, and is not pivotable relative to the solenoid brake magnet when the torque is less than the threshold value. Energisation of coil assembly enables the torque limiter body to pivot relative to the solenoid brake magnet.
