KOMPRESSOR TIL KOELEFLUIDUM

摘要

In a compressor for refrigerant fluids, the thrust bearing for a vertical crankshaft 18 comprises an annular element 52 of a material with a low coefficient of friction, which is rotatable with an upper main journal 28 and which has a flat lower radial surface, and a flat radial surface 50 machined on an upper main bearing 36 fixed in the compressor casing 12. The flat lower surface of the annular element 52 bears upon the flat radial surface 50 of the upper main bearing 36. A circlip 58 seated in a groove 56 in the crankshaft has a finger 60 for drivingly engaging a projection 54 on the thrust bearing element 52.
