LUBRICATING REFRIGERATION COMPRESSOR:OIL PUMPED BY CENTRIFUGAL FORCE THROUGH AXIAL BORE IN CRANKSHAFT |
摘要 |
<p>A hermetic refrigeration compressor has a two-stage oil pump in the vertically aligned crankshaft that is journaled in a combination thrust and radial bearing at the bottom of the crankshaft. The oil passes upward through an axial passage in the crankshaft and then outward through a radial passage which comprises the first stage of the pump. The oil then passes through a wide and shallow groove around most of the periphery of the crankshaft and is then returned through a second radial passage to another vertical passage offset from the axis of the crankshaft to move the oil upward to lubricate the various moving parts of the compressor.</p> |
