Scroll Compressor Dynamics : 1st Report, The Model for the Fixed Radius Crank

Abstract

The scroll compressor has been introduced for air conditioning application. This paper describes the dynamic behavior of the scroll machine with the fixed radius crank mechanism. The equations of motion are established for the orbiting scroll and the Oldham coupling including the friction and the motion of the Oldham coupling is shown. The bearing load, the torque and the power to drive the compressor are obtained. The overturning moment of the orbiting scroll is calculated and the stability condition is clarified.
