DISPOSITIVO PER LA COMPENSAZIONE DEGLI SQUILIBRI DI SOLIDI DI ROTAZIONE, IN PARTICOLARE DI MOLE

摘要

An apparatus for balancing a rotary member such as a grinding wheel has at least one balancing weight which is guided movably for varying its position with respect to the axis of rotation of the rotary member. The balancing position of the balancing weight is adjusted by means of at least one displacement device including an electric motor. The motor is arranged with its axis of rotary oriented radially with respect to the axis of rotation of the rotary member. The rotor of the motor can be supported by way of a thrust bearing against a main body portion.
