Title: Crankshaft and method of two-stage machining for fillet round part thereof
Inventor: IMAGAWA TOKUHIRO
IPC: F16C3/08
Filed: 2012-03-09
Abstract: PROBLEM TO BE SOLVED: To improve fatigue strength without leading to increase in manufacturing cost and weight of a crankshaft by means of stress distribution in the crankshaft wherein its fillet round (R) parts are formed with a surface of a high roughness degree and a surface of a smaller roughness degree relative to the former.SOLUTION: In fillet R parts 13,14 under stress concentration, an area of a finish machining surface Gf with a small roughness degree is assumed to be a stress concentration region thereby improving the fatigue strength of a crankshaft. In addition, the stress concentration is caused by the shape of the finish machining surface Gf so that increase is not brought about in the manufacturing cost and the weight of the crankshaft.
