METHOD FOR BALANCING ROTOR AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01M1/16 

FIELD: machine engineering.

SUBSTANCE: device for balancing the rotor includes a base, a rotation drive, roller blocks, two anisotropic supports. Each support contains sensors that record the vertical dynamic force acting on the support and sensors that record the vibration movement of the support in the horizontal plane. In this case, the device supports are rigid in the vertical direction, and in the horizontal direction perpendicular to the rotation axis, the device supports are made compliant with the possibility to move. Movable elements are pivotally attached to each support with one end. At the other end, the movable elements are attached to the traverse, a nut is fastened to the traverse, and the screw is installed therein, and on which the roller block is pivoted. The method for balancing the rotor includes placing the rotor on the balancer supports, accelerating thereof to selected rotational speed, recording the rotor oscillations, and determining the imbalance. The imbalance is measured simultaneously both in the pre-resonant and resonant modes. In this case, the dynamic force acting on the support is measured in the vertical direction, and the vibration movement of the support is measured horizontally.

EFFECT: increase the accuracy and functionality of the device by providing the possibility to simultaneously measure the imbalance of the product in both the resonant and pre-resonant modes.
