For compensating unbalance of vehicle wheels, adhesive weight elements (8) are positioned and pressed onto a determined compensation surface (17) on a wheel (7) using a balancing head (1) and a program-controlled handling device (9). 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) that presses the beginning of the endless weight strand (5) onto the beginning of the compensation surface (17) and thereafter rolls along thereon. A length cut-off device (4) is provided in 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 and a frame upper part, which is mounted on the bearing frame so as to be able to oscillate via spring bars and includes a spindle for rotatable mounting of a rotor. The frame upper part is mounted on the bearing frame via groups of spring bars, the groups being arranged at a distance from the axis of rotation of the spindle and at a distance from one another, and the longitudinal axes of the spring bars forming the spring bar groups being oriented parallel to the axis of rotation of the spindle. The spring bars forming the spring bar groups 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 (36) for the attachment of a balance weight has a clamping device (13) which has at least two mutually opposing jaws (23, 25) designed for pressing against the wheel periphery, said jaws being rotatably mounted around a common clamping axis. At least one jaw (25) is rotatable and movable to and fro in the direction of the clamping axis by means of a drive. By means of a conveyor device (6) the vehicle wheel (36) can be conveyed prone between the jaws (23, 25) of the clamping device (13). The clamping device (13) can be moved into a tilted position wherein the clamping axis is inclined at an angle of at least 30° from the horizontal out of a basic position wherein the clamping axis of the jaws (23, 25) is aligned substantially horizontally. By this means weights can be applied particularly ergonomically to the inner face of the wheel.
摘要:
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.

Disclosed is a clamping device of a balancing machine for coaxially clamping a toolholder on a spindle rotary about an axis of rotation (3), in which the coupling shank (8) is supported in the receiving socket only on discrete supports (11-15) which are spaced from each other circumferentially and lie in three relatively spaced engagement planes (E1, E2, E3) intersecting the axis of rotation (3). Four rigid discrete supports (11-14) are arranged in pairs in the first (E1) and the second (E2) engagement plane and combine to form a rigid support in a first radial direction. Formed in the third engagement plane (E3) lying between the first and the second engagement plane is a fifth discrete support (15) which effects a supporting function in a second radial direction opposite the first radial direction.
摘要:
A device for holding a constructional unit (40) of a double clutch in a balancing machine, wherein the constructional unit (40) comprises a clutch cage (41) to be balanced, with a pivot bearing (45) and driving disks (46, 47), and contains a bearing mandrel (1), which has a first clamping device (24) for clamping the pivot bearing (45) rotatably bearing the clutch cage (41) to be balanced and a second clamping device (11) for clamping the driving disk (47). One of the clamping devices (11) is adjustable in respect of the bearing mandrel (1) in the axial direction by means of an operating device (22). The bearing mandrel (1) additionally has a third clamping device (29, 57) for clamping the driving disk (46), which is stationary or adjustable in respect of the bearing mandrel (1) in the axial direction by means of an operating device (34).
