SELECTION CONSIDERATIONS FOR ROTARY COMPRESSOR SHAFT GEOMETRIES.

Author(s) : KASSOUF T. L., TOMAYKO E. A., VACCARO J. P.

Summary

CONSIDERATION IS GIVEN TO THE DEVELOPMENT OF ROTARY COMPRESSOR SHAFT GEOMETRIES TO OPTIMIZE EFFICIENCY AND RELIABILITY. THE CYLINDER TO PISTON DYNAMIC CLEARANCE IS OF PRIME IMPORTANCE WITH RESPECT TO LEAKAGE LOSSES. AN ANALYSIS OF BEARING FILM THICKNESSES AND SHAFT DEFLECTION WAS CONDUCTED. THE CHARACTERISTIC BEARING EDGE LOADING FOUND IN ROTARY COMPRESSORS ISA MAJOR RELIABILITY CONCERN. EXAMINATION OF THE CAUSES OF EDGE LOADING IS MADE AND DESIGN RESPONSES EVALUATED. MATCHING SHAFT STIFFNESS TO LOCAL BEARING STIFFNESS IS CRITICAL.
