SELF-COMPENSATING DYNAMIC BALANCER

摘要

PURPOSE: A self-compensating dynamic balancer is provided to suppress an internal vibration caused by an eccentric mass, and to reduce an interference between moving members. CONSTITUTION: A self-compensating dynamic balancer(100) includes a circular shaped main body having recessed first race(112a) and second race(112b), moving members(131,132) in the main body, a cover member coupled to the main body for covering the races, and partition members(141) installed in the races. Herein, the steel bodies(131,132) are included in the races for facing a radius direction by centrifugal force of the rotating main body. Moreover, the partition members are formed with an uniform interval in the first race. Thus, the partition members uniformly control moving range of the moving members. The steel bodies have the size and number do not interface with each other by.
