ABSTRACT:
A device for measuring rotor imbalance of a rotor is disclosed. The rotor shaft housing support for the shaft for a rotor to be balanced in a machine includes two pairs of springs disposed in two parallel planes. Each pair of springs consists of two parallel bar or rod springs that support the rotor shaft housing support in a plane of oscillation coincident with the shaft of the rotor on the machine stand in such a way that it oscillates. Each of the two bar or rod springs of each pair of springs forms part of a single-piece frame. Mounting strips are attached to the machine stand and to the rotor shaft housing.
