The invention relates to a chuck comprising a chuck casing (3) and jaws (1) moved radially outwardly and having an axially extending clamping face (17) for clamping a workpiece. The jaws (1) are guided in radial guides and are provided with two sloping guideways on an axially slidable clamping piece (4) is guided in such a manner that the jaws (1) are moved radially upon an axial sliding motion of the clamping piece (4). A jaw casing (2) accommodating the radial guides of the jaws (1) is carried for axial movement in the chuck casing (3) and is supported on the chuck casing (3) in the direction of the clamping movement of the clamping piece (4) via an axially resilient spring element (9).

The invention relates to a method and an apparatus for the unbalance compensation of vehicle wheels in which adhesive weight elements (8) are positioned on at least one determined compensation surface (17) within a disk wheel (7) and are there pressed-on, with a balancing head (1) and a program-controlled handling device (9). The invention is characterized in that the adhesive weight elements (8) in the form of an endless weight strand (5) are fed by a feed device (2) arranged on the balancing head (1) to a following roll-on roller (3). In that regard, the balancing head (1) is arranged stationarily or is connected by a frictional force transmitting connection with an execution arm (10) of the handling device (9), whereby a roll-on roller (3) of the balancing head (1) presses the beginning of the endless weight strand (5) onto the beginning of the compensation surface (17) and thereafter rolls along thereon. In that regard, a length cut-off device (4) is provided in the roll-on roller (3) or before the roll-on roller (3) and cuts-off the endless weight strand (5) of the adhesive weight elements (8) in a determined length.

A device for mounting rotors, in particular articulated shafts, in a balancing machine has a bearing frame (10) and a frame upper part (11), which is mounted on the bearing frame so as to be able to oscillate via spring bars and includes a spindle (12) for rotatable mounting of a rotor. The frame upper part (11) is mounted on the bearing frame (10) via groups of spring bars (19, 19′), said groups (19, 19′) being arranged at a distance from the axis of rotation of the spindle (12) and at a distance from one another, and the longitudinal axes of the spring bars forming the spring bar groups (19, 19′) being oriented parallel to the axis of rotation of the spindle (12). The spring bars forming the spring bar groups (19, 19′) have an elongated, slender shape such that their rigidity in an axial direction is at least 100 times, in particular at least 300 times, greater than their radial flexural rigidity.

A balancing station for positioning and holding a vehicle wheel for the attachment of a balance weight has a clamping device which has at least two mutually opposing jaws designed for pressing against the wheel periphery, the jaws being rotatably mounted around a common clamping axis. At least one jaw is rotatable and movable to and fro in the direction of the clamping axis via a drive. Via a conveyor device the vehicle wheel can be conveyed prone between the jaws of the clamping device. The clamping device can be moved into a tilted position wherein the clamping axis is inclined at an angle of at least 30 degrees from the horizontal out of a basic position wherein the clamping axis of the jaws is aligned substantially horizontally. In this way, weights can be applied particularly ergonomically to the inner face of the wheel.

In a device for clamping the rim of a vehicle wheel, in particular for mounting tires, comprising a shelf (35), onto which the rim may be deposited by one side, and comprising clamping jaws (12 to 15), which may be moved radially relative to the rim, for clamping the rim edge adjacent to the shelf (35), two pairs of clamping jaws (12 to 15), of which the paths of movement intersect at right angles, are provided. The movement of the clamping jaws (12 to 15) is generated by a cylinder (22) and is synchronized by means of a gear unit (27).
摘要:
A device for changing the rotational angle position of a pneumatic tire relative to a rim, on which the pneumatic tire is fitted to the rim, includes a manipulating device with a gripper adapted to be rotated by a positionable rotary drive mechanism and having radially adjustable gripper fingers with oppositely facing lift-off devices. Via the gripper it is possible to load a wheel into a clamping fixture, and following unseating of the tire beads from the clamped rim the pneumatic tire can be rotated relative to the rim through a computed angular difference.

In a balancing machine for the measurement of, and compensation for, any unbalance of rotors, with a sliding bearing for rotatably mounting a rotor to be balanced and a supply device for supplying the sliding bearing with a fluid, the sliding bearing includes a bearing shell with a hollow cylindrical bearing face mounting a rotor section having a cylindrical sliding face. The bearing shell is made of a hard ceramic material and the supply device is designed to supply the fluid in minimum amounts.

A pneumatic tire filling station includes a support and seal arrangement on which one side wall of the tire is supported and sealed, and a tire filling bell that presses and seals against the opposite side wall of the tire and then supplies pressurized air into the tire. The filling bell includes outer and inner rings that are concentrically slidable relative to each other. One of the rings is selected for the filling operation depending on the size of the tire. The support and seal arrangement includes plural plate members that are joined and sealed together to form a continuous support and seal surface, or moved laterally apart to allow a transport apparatus to carry and support the mounted tire from underneath. The tire filling station is adaptable to different models and sizes of mounted tires even in a mixed process flow, in an automated manner.

A filling bell can be used to fill a tubeless tire arranged on a wheel rim with a pressurized gas. The filling bell includes an annular sealing face which can be pressed onto a side wall of the tire. The filling bell also includes a central opening, into which the wheel rim may penetrate. The sealing face is formed by an annular flange which surrounds the opening and includes a plurality of wedge-shaped segments. The width of the wedge-shaped segments increases away from the opening. The wedge-shaped segments are displaceable relative to one another and substantially radially relative to the opening.
