GEAR AUTOMATICALLY BALANCING ROTATING BODIES Russian patent published in 2000 - IPC

FIELD: balancing technology. SUBSTANCE: gear can be used in automatic balancing of rotating articles in process of their running. It has bushing anchored on shaft of balanced body and two rings with eccentric masses mounted with clearance fit on outer surface of bushing for turn about its axis. In this case one of diametrically opposite halves of inner cylindrical surface of each ring has considerable coefficient of sliding friction exceeding that of the other half of ring and eccentric mass is positioned on outer surface of each ring in area of boundary of surfaces with different friction coefficients. EFFECT: increased balancing accuracy, simplified design of gear and enhanced efficiency of balancing process. 3 dwg
