PROBLEM TO BE SOLVED: To provide a secondary driver, a plate spring type flexible coupling using the secondary driver and a mechanical device using the secondary driver.SOLUTION: A plate spring type flexible coupling of reversible hub using the secondary driver can enlarge the conventional allowable maximum shaft diameter to 44% or more (ratio based on flexural plate flange outer diameter), and a main shaft of the mechanical device can increase dangerous rotation number of a shaft as a cantilever having stepped shaft diameters of shaft root and shaft tip protruded from bearing position by about 16%. Otherwise, each half W/2 of further reduced coupling mass can be subjected to moment addition (down-sizing coping) approximately on a center position of the flexural plate flange thickness, in a range of shaft tips of the respective mechanical device main shafts. |
