Abstract
The article, such as a circular saw tool or a gear wheel, has a visco-elastic synthetic-resin damping layer between, on the one hand, a portion of the body of the article which is integral with, or securely attached to, a work region adapted to interact with another article, and, on the other hand, a counter-element which extends parallel thereto. The damping layer is arranged in the interior of the article in a region covered by an outer member integral with or securely connected to the body. The parts between which the damping layer lies are connected together by the damping layer in a manner which permits shear stresses to occur in the damping layer.
Claims9
A vibration-damped disc-like rotatable article having two faces, a rotating axis and a central plane, comprising a body having a work region adapted to interact with another article;
- at least one thin damping layer consisting of visco-elastic material secured between a portion of the body which is securely attached to the work region and at least one relative thin, disc-like annular counter-element which extends substantially parallel thereto;
- and at least one disc-like annular outer member securely connected to the body;
- the damping layer being arranged between the two faces of said disc-like article and being covered by said at least one outer member, whereby the assembly permits shear stresses to occur in the damping layer.
