BALANCING MACHINE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: Balanced piece is placed on buckets 6, 7 of flexible support of machine. After rotor achieves required speed (120-3000 r/min) vibration acceleration sensors 9, 10 register information signal, that comes to microprocessor processing unit 11. Microprocessor 15 switches inputs of switch 12 in turn. Signal after its analog filtering in unit 13 in band of lower and upper frequencies (2 Hz 60 Hz) and analog-digital transformation by converter 14 comes to microprocessor 15, that using special software exercises its Fourier integral processing, its vector averaging and according to factor of influence calculation of correcting masses. Calculation results are shown on screen of visual display unit 16. Then using one of known method correcting masses location is exercised. EFFECT: increased accuracy of balancing. 3 dwg
