摘要： The device for transferring a pressure medium has a stationary outer component with first pressure medium channels and an inner, rotatably drivable component inside the stationary outer component radially spaced at a distance from the stationary outer component. The inner component has second pressure medium channels. The outer component is connected to the housing of a machine tool and the inner component is connected to the machine spindle. A first and a second intermediate member in the form of an annulus are provided. The first and second intermediate members are positioned fixedly in the space between the inner and the outer components for bridging the distance between them. The first intermediate member has at least one first connecting channel and the second intermediate member has at least one second connecting channel. The at least one first connecting channel connects one of the first pressure medium channels to one of the second pressure medium channels and the at least one second connecting channel connects one of the first pressure medium channels to one of the second pressure medium channels. The first and the second intermediate members are laterally supported at one of the components so as to each define two radially extending sealing gaps and are displaceable relative to the other of the components.

摘要： A device for transferring a pressure medium has a first stationary component and a second component that is inserted into the first stationary component such that it is rotatably drivable therein. A first annular chamber is defined between the first stationary component and the second component and has a first and a second axial end. The first axial end is delimited at least partially by the first stationary component and the second axial end is delimited at least partially by the second component. An inlet line and an outlet line are connected to the first annular chamber. The outlet line guides the pressure medium to a consuming device. Radially extending sealing slots are defined between the first stationary component and the second component at the first and the second axial ends whereby the sealing slots have adjustable slot widths. The first and the second sealing slots are simultaneously adjustable into a same direction with respect to the slot width by an axial relative adjusting movement of the first stationary component and the second component.

摘要： An apparatus for actuating clamping jaws of a chuck via an adjustment member that, to produce a rotational adjustment movement, is drivingly connected with an actuator formed from a reversible drive motor and a subsequent gear mechanism that is drivingly connected to the output side of the motor via a torque coupling. The gear mechanism is embodied as a two-stage synchronized gear in the form of a transmission gear drive having central gears that are rotatably mounted within one another and are drivingly connected via a step-type gearing to a drive member of the chuck and to the adjustment member. The central gears are drivingly and synchronously coupled via two transmission gears fixedly disposed on a transmission shaft that is rotatable about the central gears and engages the torque coupling in a load-dependent manner. The reduction stages of the transmission gear drive correspond to transmission stages of the step-type gearing.

摘要： To check the operating conditions of a power chuck, compressed air is supplied to the contact surfaces of the clamping jaws and/or of the workpiece to be clamped. Air passages are provided in the chuck body which open into the contact surfaces. The escaping air makes it possible to find out whether the contact is planar, and thus whether the clamping is exact.

摘要： A clamping device for machine tools with a power-operated chuck, the clamping jaws of which are actuatable by the clamping device via a movement converter and draw rod. A drive motor is provided with a switching element which is adjustable by axial control in a middle and two limit positions, wherein the switching element is connectable to the clamping device in one limit position and, in the other limit position, to an adjustment element connectable to an auxiliary device. The switching element is lockable in the limit positions with a machine spindle.The clamping device is thereby provided with an increased range of applications, without functions being impaired, with little structural complexity, because the switching element makes possible a clamping element integrated in the power-operated chuck to be operated using the drive motor, such that further procedures can be undertaken without changing the clamping device.

摘要： An apparatus for operating the clamping jaws of a chuck. The clamping jaws are coupled with an adjustment member which, for producing an adjustment movement is in driving connection with an adjusting drive mechanism. The latter is formed by a two-part rotary motor that is disposed externally of the main spindle and is concentric thereto. The rotary motor is rotatably mounted as a self-contained unit. One functional member of the rotary motor is driveable directly by the main spindle and is drivingly supported thereon. The other functional member is drivingly connected with the adjustment member. To maintain the clamping force, the two functional members can be positively secured to one another. To undertake an adjustment movement, the two functional members can be infinitely variably moved relative to one another.

摘要： In a chuck (1) for lathes (4), which is provided with a compensating jaw set (61) for adaptation to unequal workpieces (2) and with a centering jaw set (21) engaging at axial spacing therefrom, the centering jaws (22) are guided normal to the longitudinal axis (A) of the chuck for adjustment in centering jaw heads (16) axially displaceable to a limited extent, which centering jaw heads can be coupled through axis-parallel connecting elements (19) with a common positioning member (18). Also, the connecting elements (19) are provided with wedge surfaces (32,33), by means of which the axial adjustment movement of the adjusting member (18) is deflectable into a radial feed movement. By this design, it is possible to clamp a workpiece (2) in the region (6) to be machined reliably in centered position and thereafter compensatorily, the centering jaws (22) being positioned axis-normal to the workpiece (2) and always engaging at an equal selectable distance from the compensating jaws (62), and this independently of the workpiece diameter.
