ROTOR BALANCING DEVICE Russian patent published in 2012 - IPC G01M1/00 

FIELD: machine building.

SUBSTANCE: proposed device comprises housing accommodating spherical bearing. Inclined central shaft passes through bearing opening. Lower end of said shaft is coupled with the drive via eccentric coupling made up of intermediate eccentric ring and spherical double-row bearing. It comprises also location frame fitted to move on said shaft and to receive rotor to be balanced so that one of out-of-balance datum planes crosses the spherical bearing center. Besides it includes transducers of magnitude and angular coordinate of unbalanced mass on rotor and multichannel electronic measuring unit. Note here that aforesaid transducers represent LED, translucent screen delineated along hypocycloid with four branches, two dual photodiodes. Note that additionally used is shutter made up of narrow rectangular plate secured on central shaft extension.

EFFECT: higher accuracy and efficiency.
