DYNAMIC DAMPER
Document Type and Number:
Japanese Patent JP2015209884
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamic damper having a structure capable of restricting an eccentric state of a vibration ring without applying any exclusive stopper member and easily discharging slurry immersed into damper to an outside of the damper.SOLUTION: This invention relates to a dynamic damper in which a vibration ring is connected to an outer circumference side of a hub through a resilient body made of rubber-like resilient body. The hub has integrally a hub main body fixed to a shaft and an outward facing flange part. The vibration ring has integrally a vibration ring main body and a cylindrical part. The cylindrical part is arranged at the outer circumference side of the outward facing flange part and the inner circumferential surface of the cylindrical part is provided with a plurality of inward protrusion stoppers for use in setting a fine radial clearance between it and the outer circumferential end of the outward facing flange part. A circumferential upper location other than the location where the stoppers at the inner circumferential surface of the cylindrical part are placed is provided with a tapered slurry discharging surface where the inner diameter size is gradually expanded toward the extremity end of the cylindrical part.
