Abstract: A support is described for a bearing arrangement of a balancing machine for determining the effect of unbalance in two measuring planes. The support has a spindle that holds the component to be balanced in two planes. Vibration force pickups with a relative position indicator are provided for the determination of the fraction of the unbalance attributed to the individual plane as a function of size and magnitude. The design of a support integrally as box profile on which the spindle is laterally arranged is proposed to prevent the problems thusfar caused by the supports which influence the measured results in their reproducibility.
