    摘要： A wheel chuck includes a plurality of movable jaws mounted upon a support structure. A plurality of movable counterweights are mounted upon the support structure with each counterweight opposite from and connected to a corresponding one of the jaws. Upon rotation of the chuck the counterweights develop forces in opposition to centrifugal forces acting upon the jaws.

    摘要： An expansible mandrel for loading and unloading a work member while the mandrel is rotating, comprises a frame having an abutment and a mandrel body slidable in the frame. Two slide members are mounted for radial movement within first recesses in the body and each include a radial projection for pressing the work member against the abutment and an inclined surface facing radially inwardly. A piston is movable relative to the body and includes an inclined surface engageable with the inclined surfaces of the slides. A first spring urges the piston rearwardly to bring its inclined surface into engagement with the inclined surfaces of the slides and urge the latter radially outwardly into engagement with the work member. A second spring urges the body and slides forwardly. A coupling rod moves forwardly by a first distance to become disengaged from the body to enable the body and slides to be pushed forwardly by the second spring, and moves further by a second distance to push the piston forwardly against the bias of the first spring. The coupling rod moves rearwardly by the second distance to enable the first spring to push the piston rearwardly, and moves further by the first distance to engage the body and pull the latter rearwardly. Two weight members are mounted in second recesses of the body for radial movement. A mechanical linkage operably interconnects the weight members and respective ones of the slides such that centrifugally-induced radial outward movement of the weight members produces radial inward movement of the slides and their projections when the piston is moved forwardly.

    摘要： A power-operated chuck having a chuck body and clamping jaws that are displaceably guided in radial guides of the chuck body and that are adapted to be actuated by at least one drive element, which is displaceably guided in the chuck body and is actuated by a force producer that is operated with pressure medium. At least one chamber for receiving lubricating grease is provided in the chuck body, with lubricating bores establishing communication between the chamber and at least some glide surfaces provided for the chuck. At least one chuck component is provided that is moved during actuation of the clamping jaws, with this at least one chuck component extending into the chamber for the production of a pump movement that presses lubricating grease into the lubricating bores.

    摘要： A chuck has a chuck body generally centered on and rotatable about a rotation axis, a head displaceable on the chuck body generally perpendicular to the rotation axis, and three jaws angularly generally equispaced on the head about a clamp axis offset from and substantially parallel to the rotation axis. All of these jaws are displaceable on the head generally radially of the clamp axis. An actuator is connected to the jaws for synchronously displacing same generally radially toward and away from the clamp axis. The actuator includes an actuator member displaceable axially in the head and provided with respective actuating surfaces inclined to the clamp axis and engageable with the jaws. Two of the jaws are pivotal about respective jaw axes parallel to the axes and the other jaw is displaceable in a plane substantially including the clamp and rotation axes.
