Abstract

An adjustable pulley for use in a continuously variable transmission has two coaxial flanges at least one of which is a composite flange having an annular main section with a conical surface adjacent a reinforcing liner of wear resistant material. The liner is secured to the main section of the composite flange by a one-piece or composite disc-shaped insert one side of which has several portions affixed (such as bonded and/or riveted) to the adjacent side of the liner, and the other side of which has several portions affixed to the conical surface and/or another part of the main section. Those portions of the one side of the insert which are affixed to the liner are out of register with those portions of the other side of the insert which are affixed to the main section to thus enable the liner to move relative to the conical surface in one or more directions other than circumferentially of the main section.
