  • Connecting rod
    Patent number: 9879714
    Abstract: A connecting rod for a reciprocating piston machine may include a hollow-cylindrical connecting rod bushing for receiving a piston pin and a hollow-cylindrical connecting rod bearing having a bearing axis running parallel to a cylinder axis of the connecting rod bushing for mounting a crank pin. An elongated shaft may extend perpendicularly to the bearing axis and be disposed between the connecting rod bushing and the connecting rod bearing for connecting the connecting rod bushing to the connecting rod bearing. The connecting rod bearing may include a connecting rod saddle which is materially connected to the shaft and a connecting rod cap which is materially separated from the shaft. A connecting rod joint may connect the connecting rod saddle to the connecting rod cap. The connecting rod joint may define a Hirth serration between the connecting rod saddle and the connecting rod cap.
