METHOD OF DYNAMIC BALANCING OF ROTORS AND OSCILLATORY SYSTEM OF BALANCING MACHINE FOR ITS IMPLEMENTATION Russian patent published in 1997 - IPC

FIELD: dynamic balancing of rotors. SUBSTANCE: in compliance with proposed method rotor is supported in mobile system with two degrees of freedom. System is so adjusted that frequencies of inherent oscillations of two degrees of freedom are equal. Rotor is set in rotation. Induced oscillations of system are measured and used to determine parameters of disbalance of rotor. Rotor is supported in mobile system with the aid of elastic elements and adjustment is carried out by way of such longitudinal deformation of elastic elements that forces of each of them are equal. Speed of rotation of rotor and centrifugal force of rotation of rotor are taken as parameters. Rotor is rotated with variable speed not equal and not multiple of adjustment frequency of system, present value of centrifugal force of rotation of rotor is measured and speed of rotation of rotor is fixed by certain conditions. balancing machine has two mobile supports, suspension system with supports to mount balance article anchored with the use of elastic elements, air-measuring speed of rotation of article and aid measuring deformation force in elastic elements. The latter are installed for change of linear dimensions inside outline of mobile supports with equal angular spacings relative to balanced article and are hinged with one ends to inner outline of support and with the other ends are positioned in planes perpendicular to rotation axis of balanced article. EFFECT: enhanced reliability and efficiency of method. 2 cl, 3 dwg, 1 tbl
