Abstract

PURPOSE:To determine the position of unbalance from the relation between the unbalance position owing to the unbalance of a rotator and its vibration characteristics. CONSTITUTION:Sahft vibrations are detected by the vibration pickup 6 of a bearing 5, and the output signal thereof is inputted to a vibrometer 7, by which it is converted to an electric signal proportional to vibration amplitudes. This signal is inputted to a multiplex data input device 8. The output signal of the device 8 is inputted via an A/D converter 9 to a control arithmetic device 10. The revolution signal from a revolution detector 13 is amplified and digitized by a tachometer 12, after which it is inputted to the devive 10. The device 10 determines the relation between the number of revolutions and vibration amplitudes by vibration signal and the rotating machine signal at the point of the time when said signal is taken in and further the vibration signal is analyzed by the device 10. By using the vibration value obtained as a result, the evaluation of the cause position for unbalance is executed and the result of the diagnosis is displayed in a display device 11.
