Toothed belt, toothed belt transmission mechanism, and method for manufacturing a toothed belt

Abstract

We provide toothed belts with high durability and jump resistance. [Solution] The back portion 1c has a core wire 4 embedded in it that extends along the circumferential direction of the belt, The inner circumferential surface of the back portion 1c is provided with a plurality of teeth 1a formed at intervals in the belt circumferential direction, It includes a back rubber layer 5 formed on the outer circumference side of the belt relative to the core wire 4, and a tooth rubber layer 3 formed on the inner circumference side of the belt relative to the core wire 4, In a toothed belt 1 in which a tooth cloth is laminated on the inner circumferential surface of the tooth rubber layer 3, A fluororesin-containing rubber layer formed from a crosslinked rubber composition containing fluororesin is laminated on the inner circumferential surface of the tooth cloth, and A resin film layer containing a thermoplastic resin is laminated on the inner circumferential surface of the fluororesin-containing rubber layer.
