<P>PROBLEM TO BE SOLVED: To couple a crankshaft 5 of an internal combustion engine 2 with a motor rotation shaft 14 of an electric motor 3 while allowing a certain degree of eccentricity or misalignment of angles between the crankshaft and the rotation shaft. <P>SOLUTION: A coupling device 1 disposed between an internal combustion engine 2 and an electric motor 3 comprises a first flange plate 21 mounted on a crankshaft 5, a second flange plate 22 mounted on a motor rotation shaft 14, and a plurality of coupling arms 23 coupling the flange plates. The coupling arms 23 are composed of spring steel sheets and a plurality of sheets are radially arranged. Even when a coaxial degree between the crankshaft 5 and the motor rotation shaft 14 is low, both are coupled without difficulty. An arm portion 43 of the coupling arm 23 has a low stiffness portion composed of a slit 70 along a tangential direction in an intermediate portion in a radial direction, which lessens stress concentration in the mounting portions on the first and the second flange plates 21, 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
