Hydrodynamic Lubrication Effects of Multiple Circular Bump Pattern for a Thrust Sliding Bearing of a Scroll Compressor

The optimum texturing pattern for a thrust sliding bearing of a scroll compressor was investigated. As the basis of lubrication analysis for multiple circular bumps pattern, fundamental hydrodynamic lubrication effects of the axisymmetric circular geometry expressed by the power law formula were ana...

As the basis of lubrication analysis for multiple circular bumps pattern, fundamental hydrodynamic lubrication effects of the axisymmetric circular geometry expressed by the power law formula were analyzed using elastohydrodynamic lubrication (EHL) analysis. The optimum geometry to improve the load carrying capacity and reduce frictional force for the model geometry was discussed.

In order to clarify the robustness against accidental high load, seizure limits of a circular bump pattern were experimentally evaluated.
