Compressor coupling component for coupling a drive shaft and a movable spiral in a scroll compressor

Abstract

A compressor coupling component includes a planar main body with a first, front side and a second, rear side opposite the first side, a cylindrical coupling neck, wherein the cylinder axis of the cylindrical coupling neck runs perpendicularly to the plane of the planar main body, and the cylindrical coupling neck protrudes from the planar main body in the axial direction, a counterweight, is integrally formed on an outer region of the planar main body, and protrudes beyond the planar main body in the axial direction on the rear side of the planar main body, wherein the planar main body has opposing outer edge regions which extend as far as ends of the counterweight which oppose each other in the arc direction of the counterweight, and run linearly in the manner of increasingly spaced-apart V-legs.
