Abstract
A drive shaft balancing machine for dynamic balancing of drive shafts includes two pedestals. Each pedestal includes a spring-mounted upper part receiving a rotary spindle, a support receiving an end of a drive shaft to be balanced and a first vibration sensor detecting upper part vibrations resulting from an unbalance of the drive shaft and further involved forces in at least a first degree of freedom of motion normal to the spindle axis. On the upper part of at least one pedestal a second vibration sensor is mounted which detects the vibrations of the upper part in at least a second degree of freedom of motion. An evaluating circuit analyzes and links the vibration signals of the first and the second vibration sensors so that pitch vibration excitations of the upper part not caused by the unbalance of the drive shaft do not enter the drive shaft unbalance value computed.
