Abstract
A dynamic damper of this invention comprises: a pair of ring-shaped fixing members disposed at a predetermined interval, inserted onto and supported by a rotary shaft; a cylinder-shaped mass member having inner surface larger than the outer surface of the rotary shaft, the cylinder-shaped mass member inserted onto the rotary shaft and disposed between the pair of ring-shaped fixing members; and elastic members integrally connecting the ends of the fixing members with the ends of the cylinder-shaped mass member. The dynamic damper has enabled to down-size the configuration thereof while maintaining the performance thereof and to make the installation thereof easier.
Claims8
A dynamic damper comprising:
- a pair of ring-shaped fixing members spaced from each other by a predetermined distance, inserted onto and supported by a rotary shaft having vibrations to be absorbed;
- a cylinder-shaped mass member having an inner surface larger than the outer surface of said rotary shaft, said cylinder-shaped mass member inserted onto and spaced away from said rotary shaft and disposed between said pair of ring-shaped fixing members;
- and
- elastic members integrally connecting ends of said fixing members with ends of said cylinder-shaped mass member, said mass member being free of support except from said elastic members whereby said mass member vibrates by resonance and said elastic members are subjected to shear deformation between said mass member and said rotary shaft.
