Method for production of device for use in transforming movement of piston in circular motion, involves changing geometry of crankshaft by structural modifications, where structural modifications are used to reduce mass of crankshaft

NOVELTY – The method involves changing the geometry of a crankshaft by the structural modifications. The structural modifications are used to reduce the mass of the crankshaft, and maintaining the mechanical properties and stiffness of the crankshaft. Cavities and holes are formed in the sleeves and bars, due to the structural modifications. The conditions of maximum torque, maximum power and maximum speed for the loads applied on the crankshaft are analyzed. USE – Method for production of device for use in transforming movement of piston in circular motion. ADVANTAGE – The structural modifications are used to reduce the mass of the crankshaft, and maintaining the mechanical properties and stiffness of the crankshaft, and hence ensure that the method is improved. DETAILED DESCRIPTION – INDEPENDENT CLAIMS are also included for the following: (1) a scaling method for analyzing cavities, holes and a low weight device; and (2) a crankshaft. DESCRIPTION OF DRAWING(S) – The drawing shows a perspective view of a crankshaft.
