ABSTRACT:
Techniques for forming one piece connecting rods for coupling a piston and crankshaft to convert between reciprocating and rotary motion as might be used in an internal combustion engine or piston-type compressor are disclosed wherein the connecting rod is formed of a lightweight material such as aluminum, which material is of an inadequate hardness to form a roller bearing race. The rod includes an elongated arm portion having enlarged annular portions at opposite ends thereof and with one of those annular portions having an inner surface for receiving, in a press fit manner, a hardened steel liner to provide an outer bearing race. Rollers are then interposed between this outer race and an eccentric portion of a crankshaft while the other enlarged annular portion receives a roller bearing assembly for connection to a piston wrist pin. The annular portion for surrounding the crankshaft is of about twice the diameter of the annular portion surrounding the piston wrist pin and the steel liner which is interposed between the larger annular portion and the crankshaft rollers is a relatively thin walled annular member with cylindrical inner and outer surfaces.
