Toothed belts, toothed belt drive mechanisms, and methods for manufacturing toothed belts

Abstract

This invention relates to a toothed belt, comprising: a back surface having a core wire embedded therein extending circumferentially along the belt; a plurality of teeth formed on the inner circumferential surface of the back surface with gaps in the belt circumferential direction; and including: a back rubber layer formed on the outer circumferential side of the belt relative to the core wire; and a toothed rubber layer formed on the inner circumferential side of the belt relative to the core wire; a toothed cloth layer formed on the inner circumferential surface of the toothed rubber layer; a fluorinated resin rubber layer formed of a cross-linked rubber composition containing fluorinated resin layer formed on the inner circumferential surface of the toothed cloth layer; and a resin film layer containing thermoplastic resin layer laminated on the inner circumferential surface of the fluorinated resin rubber layer.
