PURPOSE: A dynamic damper is provided to promote the device of entire durability and stable driving by detachable vibration suppression at an arbitrary point on the axis of rotation. CONSTITUTION: A dynamic damper comprises an adapter and absorption unit. The adapter supports the axis of rotation(500) by combining detachably coupled along the outer circumference of the axis of rotation. The adapter comprises a support bracket(110), a contact bearing(120) and a housing(130). The support bracket is arranged at same intervals along the outer circumference of the axis of rotation. The contact bearing is installed respectively at the end of the support bracket. The housing is installed along the direction of the support bracket at a central hole. The vibration absorption unit approaches or separates from the adapter the mass position which is equipped at the side of the adapter. The vibration absorption unit changes a rigidity of the spring which is installed at the other side of the adapter. The vibration absorption absorbs the vibration arising from the axis of rotation. |
