This study focuses on the significant effect that a pressure difference across the fixed plate of a thrust-slide bearing has on the improved lubrication of the bearing in scroll compressor applications. A thrust slide-bearing model submerged in a refrigerant oil VG-56 was operated under pressurized conditions using R-22 as the pressurizing gas. The pressure difference across the bearing plates could be adjusted from 0 to 1.0 MPa. The frictional coefficient at the thrust slide-bearing was measured over a range of orbital speeds. A significant improvement in the bearing lubrication due to the pressure difference was confirmed. It is suggested that the improvement in bearing efficiency resulted from the formation of a fluid wedge at the sliding surfaces of the thrust slide-bearing due to both the axial loading and the fluid pressure difference.
