  • Patent number: 5726513
    Abstract: An improved connection assembly for connecting a centrifugal governor to the shaft of a fractional horsepower electric motor. The end of the rotor shaft to which the governor is mounted is provided with a circumferential ring seat and is flattened on diametrically opposed sides at the tip of the shaft. The governor assembly carrier plate is provided with a mounting sleeve that is shaped to mate with the flattened sides at the end of the rotor shaft. The mounting sleeve also has an opening that mates with the circumferential ring seat so that when the carrier plate is placed over the end of the rotor shaft, the carrier plate and the rotor shaft can be rotated 90 degrees relative to each other and the carrier plate will be captured by the ring seat to hold the governor assembly in place. A bowed retaining ring is also fitted within the ring seat and between the governor and the stator of the motor forcing the carrier plate of the governor assembly toward the end of the shaft.
