Abstract
This invention provides a manufacturing method of a dynamic damper comprising steps of: forming an annular elastic body; fitting a weight on the inner periphery of the annular elastic body and an outer pipe on the outer periphery; and bonding the weight and the outer pipe on the inner periphery and the outer periphery of the annular elastic body.
Claims8
A manufacturing method of a rotating dynamic damper comprising an outer pipe, a weight disposed inside the outer pipe and an elastic body interposed between the outer pipe and the weight, comprising the steps of:
- forming an annular uniform cross section elastic body separate from contact with any other elements of the damper;
- fitting a weight having an annular groove and corresponding flanges in an inner periphery of the annular elastic body and fitting an outer pipe on an outer periphery thereof such that the flanges extend beyond the annular elastic body and the outer pipe;
- bonding the weight and the outer pipe to the inner periphery and the outer periphery of the annular elastic body respectively, and press fitting the damper inside a hollow rotatable propeller shaft.
