Patent ID: 7133251

Claim:
A disk mounting hub for mounting a disk having opposite parallel faces between a disk outside diameter and a coaxial disk inside diameter defining a central opening therethrough, wherein said disk mounting hub comprises: a cylindrical hub body defining a hub outside diameter disposed along a central axis; a cylindrical disk mounting member disposed coaxial with said central axis at one end of said body, defining the mounting member inside diameter extending proximally from said one end of said body, and sized to be received through said disk opening, and; a coaxial hub face extending about said mounting member, said coaxial hub face defining a conical surface of revolution symmetrical about said central axis, that is disposed at an oblique hub face angle Ω relative to said central axis; and wherein said interior central portion of said disk bends toward said conical surface of said coaxial hub face at said oblique hub face angle Ω and away from parallel to the remaining exterior portion of said disk, while said remaining exterior portion of said disk remains disposed within an acute disk conning angle limit Φ min relative to a perpendicular to said central axis.
