Title:
トーショナルダンパ
Document Type and Number:
Japanese Patent JP6994364
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To adapt a natural frequency in a radial direction of a torsional damper to a resonance frequency of bending vibration that changes according to a rotational angle of a rotating shaft by preventing a decrease in durability of an elastic body, preventing a loss of assembly properties, and setting a plurality of kinds of natural frequencies in a radial direction.SOLUTION: In a rotating shaft, such as a torsional damper 201 fixed to a crank shaft 111, a vibration ring 231 is mounted to a hub 211 in which an outer peripheral surface is formed toroidally via an elastic body 221, and axial width of the elastic body 221 is made partially different so as to adapt the natural frequency in a radial direction to a resonance frequency of bending vibration of the crank shaft 111 that changes according to a rotational angle.SELECTED DRAWING: Figure 1
