ROTOR BALANCING METHOD AND DEVICE

摘要

The invention relates to measurement engineering. The inventive method consists in oscillating a rotor and a balanced body coaxial thereto about a fixed point located on the axis which is common for the rotor and the balanced body, in measuring the amplitude and phase of the rotor angular oscillations, thereby making it possible to estimate the rotor unbalance parameters on one of unbalance planes and in tangentially applying on the balanced body forces opposite to the angular oscillations of said body about the axis thereof simultaneously at each instant on the plane crossing the fixed point. The inventive device comprises a frame, a shaft which is fixed to the rotor, disposed inside the balanced body on an elastic support in such a way that it is shiftable with respect to the balanced body axis, is provided with a spherical support on one end thereof and is connected to a drive shaft by means of an adjustable eccentric. The device also comprises unbalance-measuring sensors, a reference signal sensor and a unit for processing signals received from the sensors. In addition, said device is provided with an elastic support arranged on the plane crossing the center of the spherical support disposed on the opposite end of the balanced body. Said invention increases accuracy of measurement.
