Abstract

PURPOSE: To prevent torsional oscillation of a crank shaft with simple constitution by providing a torsional damper coaxially with the crank shaft, supported either by a one-way clutch or a generator.
CONSTITUTION: A torsional damper 46 provided coaxially at the left end of a crank shaft 26 is made of a bowl-like bracket 47, a cylindrical weight 48 and a cylindrical elastic body 49 made of rubber or the like interposed and bonded between them with the bracket 47 fixed to a one-way clutch 33 with a bolt 34. This torsional damper 46 has a natural frequency different from that of the crank shaft 26, the crank shaft 26 is rotated by driving of an engine 8, and a torsional vibration is absorbed and damped, if generated. In this case, as the one-way clutch 33 is lighter than a generator 38 provided at the right end of the crank shaft 26, right and left weight balance is made favorable by the torsional damper 46. Thus, the torsional vibration of the crank shaft can be prevented with the simple constitution.
