  • Patent number: 8057196
    Abstract: A compressor assembly includes a compressor coupled to a motor via a belt drive. The belt drive provides a speed reduction between the motor and compressor and causes the compressor shaft to rotate in the direction opposite that of the motor shaft. The relative values of the mass moments of inertia about the axes of rotation of the rotating motor and compressor shafts are engineered to be inversely proportional to the relative shaft speeds, allowing the mass moments of inertia to be balanced to at least substantially eliminate torsional vibration.
