Method for determining influences of noise from machine environment to measuring accuracy of oscillation measuring balancing machine, involves computing imbalance comparison value from combined signals by using evaluation process of machine

摘要

The method involves combining a measurement signal of a vibration absorber i.e. vibration sensor (8), of a balancing machine (1) with a predetermined rotary speed signal, where the measurement signal is detected by a stationary motor drive (4). An imbalance comparison value describing environmental influence is computed from the combined signals by utilizing signal evaluation process of the balancing machine. The speed signal is produced by a signal generator (20) and transmitted to signal evaluation devices (10, 14). The generator is attached to an input of the signal evaluation devices. Independent claims are also included for the following: (1) a device for determining influences from machine environment to measuring accuracy of an oscillation measuring balancing machine (2) a balancing machine.
