Patent ID: 7645204

Claim:
A method for improving resistance to bearing spin in a pulley assembly, said pulley assembly comprising a polymeric pulley having an integral bearing concentrically positioned therein, said method comprising: providing a polymeric pulley having a central axial hub exhibiting a concentric axial bore therethrough, said concentric axial bore having an axial bore surface; providing a metal tubular insert adjacent said axial bore surface, said metal tubular insert having an outer surface and an inner surface, wherein said outer surface of said metal tubular insert is coated with a brass or zinc coating to enhance adhesion of said outer surface of said metal tubular insert to said axial bore surface of said polymeric pulley; providing an integral bearing having an outer axial race and an inner axial race, wherein said outer axial race of said integral bearing is coated with a phenolic primer; applying at least one drop or bead of a fastening element onto said outer axial race having said phenolic primer coated thereon; and forming said pulley assembly wherein said metal tubular insert is fixedly mounted in said axial bore of said polymeric pulley, and said outer axial race of said integral bearing is fixedly mounted to said inner surface of said metal tubular insert, wherein said pulley assembly retains constant position of said integral bearing relative to said polymeric pulley.
