THE HIGH MECHANICAL EFFICIENCY OF ROLLING-PISTON ROTARY COMPRESSORS.

Author(s) : ISHII N.

Summary

THE STUDY PRESENTS A COMPUTER SIMULATION WHICH DEMONSTRATES THAT THE MECHANISM FOR THIS INCREASED MECHANICAL EFFICIENCY IS THAT THE ROLLING PISTON EFFECTIVELY DECREASES THE POWER LOSSES DUE TO MECHANICAL FRICTION. FROM THE WEAR ON THE CRANKSHAFT AFTER A 2,000 HOUR ENDURANCE TEST OF A COMPARATIVELY SMALL COOLING-CAPACITY ROLLING-PISTON ROTARY COMPRESSOR, IT CAN BE SEEN THAT THERE IS FLUID LUBRICATION BETWEEN THE ROLLING PISTON AND THE CRANK PIN. THE OIL VISCOSITY COEFFICIENT IS GIVEN ON THE BASIS OF EXPERIMENTS ON OIL PRESSURE AND TEMPERATURE. THE FRICTIONAL STATE BETWEEN THE OTHER PAIRS OF MACHINE ELEMENTS IS CLASSIFIED INTO 2 REPRESENTATIVE BOUNDARY FRICTIONS.
