Being the flywheel device of the motive for action

摘要

PROBLEM TO BE SOLVED: To provide a flywheel device for motor having a compact size in the axial direction and capable of adding an inertial mass effectively.;SOLUTION: The flywheel device 1 is equipped with a drive plate 11 having a ring-shaped projection 11b and attached to a crank-shaft 2a concentrically and a mass ring 12 which has a ring-shaped recess 12a, is attached to the drive plate 11 concentrically by fitting the recess 12a on the projection 11b of the drive plate 11, and transmits the torque of an engine 2 to the input shaft 31 in the condition that its torque variation is reduced.;COPYRIGHT: (C)2003,JPO
