STRUCTURE FOR COUPLING CAULKING OF FRAME IN HERMETIC TYPE COMPRESSOR

摘要

PURPOSE: A structure for coupling caulking of a frame in a hermetic type compressor is provided to easily manufacture caulking protrusions on a frame. CONSTITUTION: A frame body(31) is formed by pressing a board, having a through hole(32) vertically passing through the frame body. A boss part(40) is installed by passing through the through hole of the frame body to support a crank shaft rotatively, and has a flange(45) to be coupled with the frame body. A caulking part is formed on the flange of the boss part and the frame body, and includes a plurality of caulking protrusions(34) and caulking holes(46). Supply grooves(35) are formed on a surface opposite to the other surface where the caulking protrusions are protruded, to form the caulking protrusions.
