FIELD: measuring equipment engineering. ^ SUBSTANCE: oscillating movement is induced onto rotor and balanced body coaxial thereto relatively to fixed point on common axis of rotor and balanced body. Amplitude and phase of angular oscillations of rotor are measured, which are utilized to evaluate parameters of rotor unbalance in one of unbalancing planes. Simultaneously in every time moment in the plane passing through fixed point, forces are applied to balanced body along tangents, opposing angular oscillations of body relatively to axis. Device has column, shaft held on rotor, mounted inside the balanced body on resilient support with possible movement thereof relatively to axis of balanced body, on one end provided with spherical support and connected by adjustable eccentric to drive shaft, and also unbalance value measuring indicators, bearing signal indicator and block for processing signals from outputs of indicators. Device additionally has resilient support, positioned in the plane passing through center of spherical support, positioned on other end of balanced body. ^ EFFECT: improved precision of measurements. ^ 2 cl, 4 dwg |
