PROCESS OF BALANCING STRUCTURALLY NON-UNIFORM RIGID ROTOR WITH INCLINED DISC Russian patent published in 2000 - IPC

FIELD: radio engineering. SUBSTANCE: invention is intended to correct moment disbalance of rigid rotor made from structurally non- uniform material with disc inclined to rotation plane at stages of design and subsequent adjustment balancing with due account of structural peculiarities of rotor. Internal mounting surface of disc is coaxial to rotation axis and two side washers whose moment disbalance is characterized by centrifugal moment of inertia, is equal in value and opposite by sign to moment disbalance of disc are used to fix it in working position. Geometrical parameters of rotor are so chosen that dependence following from equality of values of centrifugal moments of inertia of inclined disc and oblique washers is adhered. Thickness of layer of material subject to removal either from external surface of disc or from external surfaces of oblique washers depending on source of residual moment disbalance is computed by results of adjustment balancing on balancing machine. EFFECT: simplified design and reduced cost of rotor. 2 cl, 5 dwg
