ABSTRACT:
An apparatus for unbalance measurement on a rotary member comprising a rotary mounting device for the rotary member and an oscillatable support for the rotary mounting device for supporting same on the foundation of the apparatus. A force and/or oscillation measuring equipment is operatively disposed between the foundation and the rotary mounting device for measuring centrifugal forces and/or oscillations which result from unbalance of the rotary member. To determine the mass of the rotary member in the rotary mounting device, the apparatus measures the force due to the weight of the rotary member, disposed in the path of transmission of force between the rotary mounting device and the foundation.
