Title:
VIBRATION-PROOF STRUCTURE FOR ROTATING BODY
Document Type and Number:
WIPO Patent Application WO/2015/198792
Kind Code:
A1
Abstract:
Provided is a vibration-proof structure whereby rotational vibrations of a rotating body caused during a cutting process can be more effectively reduced. The vibration-proof structure is configured so that there are provided, in the interior of the rotating body (2), multiple shaft members (20) arranged in the longitudinal direction of the rotational axis (X) of the rotating body and at least one layer of multiple cylindrical members (22) disposed over the shaft members while being coaxial with the rotational axis (X) and arranged in the longitudinal direction of the rotational axis (X), and the boundary position between longitudinally adjoining shaft members (20) and the boundary position between longitudinally adjoining cylindrical members (22) are located at different positions along the longitudinal direction.
