ABSTRACT:
A centrifugal actuator for mounting on a rotor shaft, the actuator being capable of movement from a first or start position to a second or run position, is provided having a base portion with a pair of opposed, mirror image actuator levers biased towards the first position. The levers are urged to the second position by centrifugal force when the shaft rotates. The levers are cooperatively connected to a sleeve, the sleeve being capable of axial movement allowing the sleeve to move from the first to second position in response to the movement of the levers. The sleeve has a collar and a shoulder portion for the seating of the actuator levers. Unique ramp structures extending from the sleeve collar to the seats on the shoulder cause the actuator levers to seat properly during assembly thereby allowing automated assembly and preventing field failure due to misseating of the actuator arms.
