ABSTRACT:
A crankshaft including an eccentric cranked section which is divided into two parts. A unitary inner ring is force fit over the outer surfaces of both parts of the cranked section of the crankshaft. At each axial end of the inner ring, a groove is opposite a hole in the shaft. A connecting pin extends between them. This prevents rotation of the inner ring around the cranked section of the shaft. For strengthening the cranked section, there is a continuous bore hole through both of its parts and a connecting screw extending through the bore hole. A support for the connecting rod engages the crankshaft cranked section at the bearing inner ring.
