COUNTERWEIGHTING SCROLL COMPRESSOR FOR MINIMAL BEARING LOADS.

Author(s) : NIETER J. J., DEBLOIS R. L.

Summary

THE AUTHORS DESCRIBE A NEW OPTIONAL METHOD FOR COUNTERWEIGHTING A SCROLL COMPRESSOR. THE TECHNIQUE INVOLVES SIZING AND POSITIONING COUNTERWEIGHTS ON THE DRIVE SHAFT SUCH THAT THE RESULTANT LOAD IMPARTED BY BOTH THECOMPRESSION PROCESS AND BY THE INERTIA OF THE MOVING SCROLL ELEMENT IS NEARLY CANCELLED AT THE DRIVE SHAFT SUPPORT BEARINGS. CONSEQUENTLY, EXPENSIVE BEARINGS COULD BE REPLACED WITH LOWER COST BEARINGS WHILE MAINTAINING OR IMPROVING RELIABILITY AND LIFE OF THE COMPRESSOR. SOME INCREASE IN VIBRATION OF FRAME ALSO CAN BE EXPECTED. THUS, A TRADEOFF MUST BE MADE BETWEEN REDUCED BEARING LOADS AND INCREASED VIBRATION.
