Abstract
A refrigeration compressor having a plurality of pistons reciprocated by a crankshaft and in which the crankshaft is made up of two parts that are permanently fixed together by means of a sleeve which is press fit over adjacent ends of the two pieces of the crankshaft. The adjacent ends also have complementary parts which inter-engage with one another so as to hold the throws of the crankshaft parts in proper relationship and timing to one another. A bearing is mounted on the press fit sleeve and a split bearing support then embraces the bearing so as to hold the assembly in precise support in the compressor frame. The split bearing support includes a lower bearing support case to which is bolted an upper semi-circular cap. The support case is also semi-circular and has a radial split cut into it which is bridged by a tapered pin so that upon tightening of the pin the bearing support case is urged apart or expanded to thereby be tightly mounted in the compressor frame.
