Summary

Scroll compressors are widely used popular in HVACR industry due to their efficiency and versality. Radial compliance is one of key mechanisms allowing these compressors to achieve the high level of efficiency. Conventional radial compliance mechanism is typically integrated in the orbit scroll bearing. Because of uncompensated scroll inertia, the conventional mechanism results in higher noise and flank friction at high speed and/or leakage at low speed. There is a wide variety of mechanisms for inertial unloading at high speed, however they introduce extra parts and result in higher scroll overall inertia. A novel compact compliance mechanism requiring minimum additional parts was proposed in the paper. The new mechanism is located within the main bearing. It results in scroll flank force to be almost independent on the compressor speed. The paper describes functionality and design parameters of the mechanism, force analysis, analytical and experimental evaluation of the mechanism functionality and performance.
