ABSTRACT:
An arrangement for driving a measuring spindle of a balancing machine has a friction wheel which is drivable by an electric motor and which can be brought into and out of a condition of driving relationship with the measuring spindle. The electric motor and the friction wheel form a motion unit supported movably about a mounting assembly which is disposed on the machine frame structure and which is arranged in displaced relationship with the axis of the rotor of the electric motor. A torque which is produced about the mounting assembly when the rotor of the electric motor is accelerated causes movement of the motion unit thereby to produce the driving connection between the friction wheel and the measuring spindle.
