Abstract
An unbalance measuring machine has an arrangement for clamping and release a motor vehicle wheel or other rotary member on a motor-driven shaft. The machine has a bar which is guided movably in the shaft in its axial direction. The bar is engaged at one end with the rotary member and at the other end with a belt pulley via interengaged screw threads. When the belt pulley is driven by the drive motor in one direction of rotation, the bar axially clamps the rotary member on the shaft to hold it fast. When the belt pulley is driven by the drive motor in the other direction, the bar moves in the opposite direction to release the rotary member.
