Abstract
Official abstract text for this publication.
A dynamic damper assembly may include a plurality of bodies arranged at predetermined intervals on an outer peripheral surface of a drive shaft, and an elastic body formed to surround each of the bodies and fixing each body to the drive shaft.
First claim
Opening claim text (preview).
What is claimed is: 1. A dynamic damper assembly comprising: a plurality of bodies arranged in a peripheral direction of a drive shaft at predetermined intervals on an outer peripheral surface of the drive shaft; and an elastic body formed to surround each of the bodies and fixing each body to the drive shaft, wherein a slit hole having a slit shape that is elongated in a longitudinal direction of the bodies is formed between a first body and a second body of the bodies, wherein masses of the bodies are different based on at least one of varied radial thicknesses and arc lengths of the bodies in the peripheral direction of the drive shaft, and wherein a resultant of centrifugal forces of the bodies is set to be “0”. 2. The dynamic damper assembly according to claim 1 , wherein distances from a center of rotation of the drive shaft to outer peripheral surfaces of each elastic body surrounding the respective body are equal to each other. 3. The dynamic damper assembly according to claim 1 , wherein each elastic body surrounding the respective body has a same size. 4. The dynamic damper assembly according to claim 1 , wherein the slit hole is formed between adjacent bodies. 5. The dynamic damper assembly according to claim 4 , wherein the slit hole comprises at least one connection portions to connect the adjacent bodies. 6. The dynamic damper assembly according to claim 1 , wherein the elastic body has seating portions formed with ends in a longitudinal direction of the drive shaft extending outward. 7. The dynamic damper assembly according to claim 1 , wherein the drive shaft and inner and outer peripheral surfaces of the elastic body form a concentric circle.
