  • Publication number: 20080060465
    Abstract: A damping material for mechanical parts includes a non-coupling interface that comes into contact without being metallically coupled. The non-coupling interface is formed from the surface to a predetermined internal depth, and may assume a non-penetrative structure. In such circumstances, it is preferable that a depth of the non-coupling interface be equal to, or greater than 20% of a dimensional thickness in the same direction. The non-coupling interface may be formed so as to penetrate from one surface to another surface. The damping material for mechanical parts is a gear damping material for forming a gear having damping characteristics, and has: a main body portion formed in a ring shape or in a disk shape; and a predetermined portion to form teeth shape provided at the outer periphery side face or at the inner periphery side face. The non-coupling interface is formed from at least one end face in an axial direction of the main body portion.
