First Claim
Patent Images
1. A product comprising:
- a transfer gear for use in a vehicle comprising;
a hub;
a web that extends radially from the hub;
a plurality of teeth circumferentially disposed around the web; and
a friction damping component carried by the hub, carried by the web, or carried by both the hub and the web, and wherein the friction damping component includes at least one non-bonded surface that contacts an adjacent surface and damps vibrations in the gear.

Abstract
One exemplary embodiment includes a transfer gear that carries a friction damping component that damps vibrations in the gear. The friction damping component may be carried on or in a hub, a web, or both the hub and the web, and may include at least one non-bonded surface that contacts an adjacent surface.

13. A product comprising:
a transfer gear for use in a vehicle comprising; a hub that defines a cavity delimited by at least one internal surface of the hub; a friction damping component that includes at least one non-bonded outer surface that contacts the at least one internal surface of the hub and damps vibrations in the gear; and a sealer that seals the friction damping component in the cavity and protects the at least one non-bonded outer surface against exposure to lubricant fluids. - View Dependent Claims (14, 15, 16)

17. A product comprising:
a transfer gear for use in a vehicle comprising; a hub; a web that extends radially from the hub and includes at least one face; a friction damping component that includes at least one non-bonded surface that contacts the at least one face and damps vibrations in the gear; and one or more joints that fasten the friction damping component to the gear and protect the non-bonded surface against exposure to lubricant fluids. - View Dependent Claims (18, 19, 20)

21. A method comprising:
-
providing a transfer gear that includes a hub, a web extending radially from the hub, and a plurality of gear teeth circumferentially disposed around the web; providing a friction damping component that includes at least one non-bonded surface; and disposing the friction damping component in or on the hub, the web, or the hub and the web; causing to power transfer gear to be vibrated so that frictional contact between the at least one non-bonded surface and the adjacent surface damps vibrations in the gear. - View Dependent Claims (22)
