Effect of Radial Compliance Mechanism on Rotor System and Bearing Load for Scroll Compressor

Abstract:

The imbalance caused by eccentric sleeve radial compliance mechanism rotor system is a main issue in scroll compressor. In this study, the mechanical model of the structure with the eccentric sleeve behind the orbiting scroll is established, the offset level of the main and second balance weight inertia force action line and inertia force action line of the eccentric weight, as well as the effect of this deviation on the second balance and the main and second bearing loads were investigated in terms of working principle, structure and loading. The results show that the structure has great influence on scroll compressor rotor system balance in reducing orbiting radius regulation. It is suggested that the correlated parameters should be optimized in designing radial compliance mechanism structure.
