Title: Flexible plate and flywheel assembly therewith
Inventor: DOUMAN TAISUKE
IPC: F16F15/315
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To absorb bending vibration of a crank shaft and reduce noise at the time of acceleration without degrading clutch changing performance by applying anisotropy to flexural rigidity in an intermediate part between a flywheel mounted part and its center part. SOLUTION: For a flexible plate 4, its inner periphery part 4b is fixed at the flange part 3a of a crank shaft 3, and a flywheel 5 is fixed at its outer periphery part 4c. A plurality of through-holes 8 are disposed at uneven intervals in the circumferential direction at the intermediate part 4d of the inner periphery part 4b and the outer periphery part 4c, and a drawing part 12 of elliptic shape is formed. Therefore, the flexible plate 4 reduces its flexural rigidity without reducing its translational rigidity by the through-holes 8 and the drawing part 12. If bending vibration is generated by rotational force from the crank shaft 3 of an engine, bending vibration is hardly transmitted to the flywheel 5 because the rigidity of the flexible plate 4 is low, thus it is possible to suppress excitation of a vehicle body and reduce noise at the time of acceleration.

The wave propagates to a magnet and a grinding vibration effect is enhanced, thereby pressing a grindstone 3 fixed to the tip of the vibrator 2 to a polishing surface for processing. Then, the electrostrictive material 2 expands and contracts due to the application of signal voltage from high frequency power supplies 40 and 41, and the circular vibrator 1 bonded with said material 2 generates a bending vibration. Or high frequency electrical fields having a phase difference of 90 deg. in terms of time generates a progressive wave moving in one direction with time elapsed, while two standing waves are superimposed with each other. And the ultrasonic progressive waves work upon the grindstone 3, thereby enabling polishing a workpiece pressed with the grindstone 3.
