ABSTRACT:
A refrigeration compressor includes a polyamide annular thrust bearing pressfit within a countersunk recess in the rotor aperture and having radially extending lubricating oil grooves on a lower surface thereof. A vertical crankshaft being concentrically disposed within and secured to the rotor at one end and being journalled for rotation within a vertical bore defined by a bearing hub formed in a frame. The bearing hub supports the rotor and crankshaft combination. The bearing hub includes an upper end face which is machine ground and polished to a smooth surface and which is in contact with the smooth lower surface of the thrust bearing thereby forming a frictional pair. A reduction in mechanical friction and power consumption is realized by use of the polyamide thrust bearing and the smooth polishing of the hub upper end face thereby increasing the overall efficiency associated with the refrigeration compressor.
