Numerical analysis of journal bearing in rotary compressor.

Author(s) : SI S., DO G.

Summary

In this study, in order to investigate the characteristics of journal bearing in rotary compressor, numerical analysis of hydrodynamic lubrication and dynamics of the journal were carried out. The Reynolds equation of journal bearing for periodic compression force of rotary compressor were solved to obtain the locus of journal. The lobe bearing is adopted for comparison to the current plain journal bearing. Analysis results compare the minimum film thickness and frictional loss of both bearings. The analysis results reveal that the lobe bearing can improve the efficiency and the reliability of rotary compressor.
