Connecting rod for hermetic refrigerating compressor

Image Number 5 for United States Patent #6272971.

The invention concerns a connecting rod for a hermetic refrigerating compressor, in which the connecting rod forms the mechanical connection between a crank and a piston. The purpose of the invention is to reduce wear in the crank bearing of the compressor with simple means. This is obtained by reducing compressive stresses in the connecting rod by making a cut-out in the connecting rod near the crank bearing. The cut-out causes deflection of compressive stresses, so that they are distributed over a larger share of the crank bearing surface. Also the outer shape of the connecting rod is adapted, so that also here the compressive stresses are distributed over a larger bearing surface. This reduces the wear on the crank bearing of the compressor and increases the life.
