Abstract
PURPOSE: To measure both the quantity of eccentricity of a rotary object and the position of a peak of vibration due to the eccentricity simply by using a configuration that consists of a reference frequency generator, detector, BPF, indicator, selector circuit and synchronous luminous circuit.
CONSTITUTION: When the signal change-over switch 800 is turned to the contact 801, the timing lamp 700 emits light ray with a period of 50Hz exactly. The number of rotation of the rotary object 902 is adjusted to set itself to 3,000rpm. At this time, only the primary component of the rotation is separated from a vibration signal, which is detected by the vibration pickup 100, by the BPF300, the indicator 550 is deflected by the meter amplifier 500. The value is the quantity of vibration of the rotation. Next, when the switch 800 is turned to the contact 802, the timing lamp 700 is lighted at a point voltage of the vibration signal changes from negative to positive. It is a point that leads the peak of vibration by 90°. Accordingly, by reading a position at which the rotary object 902 locks as if it stopped at the location the vibration pickup 100 is provided, the fact that the point returned by 90° from the said position is the peak of vibration can be known.
