ABSTRACT:
A drive assembly for connecting a governor (10) to an engine (12) for absorbing torsional vibrations in the shaft while providing a direct drive between the engine and the governor during overtravel. The drive assembly includes a shaft (16) driven by the engine (12) and a rotor (24) mounted on the end of the shaft and received within a housing (18) mounted for rotation about the shaft. The housing contains magnets (35 and 37) which interact with magnetically permeable portions of the rotor (24) to establish a magnetic flux coupling therebetween. During operation, torsional vibrations in the drive shaft (16) will tend to rotate the rotor (24) relative to the housing (18), thereby reducing the torsional vibration imparted from the engine (12) to the governor (10). Pins (32 and 34) limit the amount of relative movement between the rotor and the housing so that the rotor engages the pins, providing the direct drive to the governor during overtravel. The housing includes a gear (20) mounted about its circumference for driving a pinion (22) leading to the governor (10).
