ABSTRACT:
A bearing engagement structure for a hermetic compressor includes a unitary cylinder-frame member having an opening in a central portion thereof, the opening having an internal screw thread formed along an inner periphery thereof, and a journal bearing including an external screw thread formed along an upper outer periphery thereof and a body formed with a polygonal shape in a lower portion thereof. The body of the journal bearing is formed with a circular, square or hexagonal shape. The bearing engagement structure allows the compressor to employ a unitary type connecting rod which is to be engaged to a crank shaft, for thereby obtaining an advantageous strength of the connecting rod with regard to a compressing force and a tension thereof.
