An end effector is disclosed for use with a surgical robotic manipulator and a cutting accessory. The end effector comprises a nose tube for receiving the cutting accessory and an actuator for driving the cutting accessory. The end effector may also comprise a mounting fixture for coupling the end effector to the surgical robotic manipulator and a handle for gripping by the user. The handle may be coupled to the nose tube and configured to rotate about the axis of the nose tube. The end effector may also comprise a lever coupled to the handle and moveable between depressed and released positions. The end effector may further comprise an activator coupled to the lever and configured to interact with a sensor for sensing the position of the lever.

To provide a simple-structured cam clutch that does not require precise control and is operable with a smaller drive force and less prone to damage on cam surfaces or inner and outer raceways. The cam clutch includes a plurality of cams circumferentially arranged between an inner race and an outer race and supported by a cage member, and a selector capable of changing an orientation of the cams. The selector includes a driven part allowing a rotation angle thereof to be controlled relative to the inner race or outer race to which the cage member is fixedly attached, and a selector body circumferentially displaceable relative to the driven part in a resilient manner by a spring-loaded mechanism. The selector body includes a cam orientation control protrusion capable of changing the orientation of the cams by making contact with the cams.

An actuating device for a transmission has an adjusting element which can be moved in rotation by way of an actuator. At least one actuating element is arranged on one side of the adjusting element and can be moved in translation as a function of a rotation movement of the adjusting element. Roller bodies between the adjusting element and the actuating element concerned are arranged in such manner that each roller body engages in a ramp-shape contoured groove of the adjusting element and in a ramp-shape contoured groove of the actuating element concerned. The roller bodies, which are arranged between the adjusting element and the actuating element concerned, are arranged in at least two concentric roller body rings. Alternatively, or in addition, bearing bodies which serve to support the adjusting element on a housing-side base element are arranged in at least two concentric bearing body rings.

A method of assembling a clutch includes assembling a wedge chain by connecting a plurality of wedges together with links such that the wedges are movable relative to each other, and wrapping the wedge chain around an inner race. The method further includes connecting an end one of the links to an end one of the wedges to secure the chain to the inner race. The may also include installing the inner race into an outer race such that the wedge chain is radially disposed between the inner and outer races.

A pumping device for a seat of a vehicle is proposed. In the pumping device, a plurality of pressure members is provided along an outer circumferential surface of a brake drum, and braking operation is performed through the pressure members moved when the brake drum rotates, so that friction between the brake drum and a housing can be avoided and thus deterioration of operational performance is prevented. In addition, the shape of the brake drum is simplified and the number of components is reduced, so that weight and size of the pumping device, and production cost are reduced, and fuel efficiency increases.
