Résumé

This paper presents theoretical calculation results of the axis excitation force associated with compression operation of a three-cylinder rotary compressor, and shows that the axis excitation force is reduced to about 30% of that of a two-cylinder rotary compressor. Our paper has performed an axis behavior analysis, and clarifies that the axis runout amplitude of the upper end of the crankshaft during high-speed rotation is reduced by 55% by improving counter balancer arrangement. To demonstrate these effects, we measured vibration and sound of a three-cylinder prototype with a 20% larger displacement volume than a two-cylinder maximum model, and compared them with that two-cylinder model. The vibration due to compression force fluctuation was reduced to less than 30%, and the vibration due to axis runout moment was also reduced to about half. The sound overall value at a rotation speed of 90 rps was reduced three decibels.
