摘要： A clutch assembly to adapt a clutch for use with a mud motor and a power take off (PTO) assembly is provided. The motor includes a body and a driving shaft, wherein the PTO assembly includes a PTO housing and a driven shaft. The clutch assembly includes a centrifugal clutch and a clutch housing. The clutch includes a hub that engages with the driving shaft, a shoe containing a plurality of fly-weights and an elastic member, and an outer drum casing adapted to selectively engage with the plurality of fly-weights when the rotational speed of the driving shaft is above a predetermined threshold. The clutch housing surrounds the centrifugal clutch and allows the clutch to be installed between the body of the motor and the PTO housing. The outer drum casing has a shaft fixed thereto that is adapted to engage with the driven shaft of the PTO assembly.

摘要： A flywheel is attached to a shaft of a turbine. As the shaft rotates, the flywheel swings outwards away from the shaft and regulates the angular velocity of the rotating shaft. In an embodiment, there are multiple flywheels attached to the shaft. In another embodiment there is a first flywheel that controls a second flywheel. In another embodiment, the flywheel has adjustable or centrifugal displacement of counterbalanced masses for effective rotational diameter with effective rotational balance. In another embodiment, a small pilot centrifugal displacement flywheel may control a clutch by rotational velocity and may include a hysteresis control. An example of a clutch may limit that degree to which the arms of the flywheel may be extended and/or retracted. In another embodiment, a small pilot centrifugal displacement flywheel controls the hysteresis of a centrifugal flywheel displacement.

摘要： Described herein is a system, method of use and Self Retracting Lifeline (SRL) apparatus using a system that governs a dynamic response between members causing a halt in relative motion between the members. Magnetic interactions, eddy current drag forces and centrifugal and/or inertial forces may provide various mechanisms of governing movement.

摘要： Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.

摘要： A centrifugal clutch 200 includes a first drive plate 210 rotationally driven directly by a driving force of an engine and a second drive plate 220 frictionally in contact with the first drive plate 210. The first drive plate 210 includes a bulging body 215 on a supporting portion 214 bulging toward the second drive plate 220. The second drive plate 220 is rotationally driven together with the first drive plate 210 while allowing rotational displacement relative to the first drive plate and includes clutch weights 230. The bulging body 215 is made of a cylindrical roller. The clutch weight 230 is formed with a driven portion 232. The driven portion 232 has a pressing body 232a in contact with the bulging body 215. The pressing body 232a obliquely extends rearwardly and outwardly in a rotational drive direction of the first drive plate 210.

摘要： The present disclosure is directed to a gas turbine engine structure and method for reducing or mitigating bowed rotor. The method includes coupling a rotor assembly to a mechanical energy storage device via a clutch mechanism when the rotor assembly is at or below a speed limit below an idle speed condition; storing mechanical energy at the mechanical energy storage device via rotation of the rotor assembly at or below the speed limit; releasing mechanical energy from the mechanical energy storage device to rotate the rotor assembly following shutdown of the gas turbine engine; and rotating the rotor assembly via the mechanical energy from the mechanical energy storage device.

摘要： A centrifugal clutch apparatus can include a driving-side rotational member rotatable around a shaft member connected to a driving device; clutch devices mounted on the driving-side rotational member and movable radially-outward of the driving-side rotational member. A driven-side rotational member rotatable independent from the driving-side rotational member can be arranged for covering the driving-side rotational member and can have an inner circumferential surface to engage with the clutch devices. Friction members can be adapted to be abutted against the inner circumferential surface so as to transmit the driving power of the driving device to the driven-side rotational member. The inner circumferential surface of the driven-side rotational member can be formed with a groove and a tensioning member formed as a ring-shaped member can be snap-fitted into the groove and held therein under a radially-outward biasing force.

摘要： A transmission clutch module including inner and outer races, a plurality of race engaging pawls and an actuator ring incorporates an actuator having a rotatable spool header adapted to rotate an attached actuator lever between at least two angular positions. The actuator lever moves the actuator ring to selectively block the pawls so inner and outer races may freewheel relative to one another in at least one operating mode. The actuator may be electric or hydraulic powered, and may be spring-biased to a default position in event of power failure. An elongated axially moveable plunger is secured to and supported within a piston at a first end, and has a radially extending pin at its second end. A fixed spool sleeve to which the spool header is supported includes a helical slot through which the pin extends. As the plunger moves reciprocally, the pin undergoes both translational and rotational movement.
