Automatic balance adjusting rotor for centrifuge apparatus

An automatic balance-type rotor for a centrifugal separator is provided to prevent excessive vibration caused by unbalance of the centrifugal force by precisely compensating unbalance by horizontally transferring a rotor lever through a block worm gear and a power transmitting unit. An automatic balance-type rotor for a centrifugal separator is composed of a rotor lever(100) for supporting a bucket equipped with samples at both ends and having a block worm gear(104) installed in the center of the upside in a longitudinal direction; a rotor body for supporting the rotor lever to precisely move the rotor lever in a horizontal direction; a lever transfer motor(180) installed at the rotor body; and a power transmitting unit(200) for horizontally moving the rotor lever by transmitting rotating power of the lever transfer motor to the block worm gear.
