In an engine having an arrangement of cylinders with reciprocating pistons for drivingly rotating a crankshaft, the following assembly is provided comprising:
a crank journal orbitally linked to the crankshaft and having a central axis offset and parallel to a central axis of the crankshaft;
a spider bearing coaxially fixed to said crank journal and including a plurality of round cavities;
a wrist pin fitted within each of said plurality of round cavities
a plurality of connecting rods each having opposite ends including a first end structured for pivotal linkage to a respective one of the reciprocating pistons and an opposite second end structured for pivotal receipt within a respective one of said plurality of round cavities and about said wrist pin to pivotally link said second end to said spider bearing; and
wherein reciprocating movement of the pistons within the cylinders drives the connecting rods to rotate the spider bearing, crankshaft journal and crankshaft.
