Abstract

The invention discloses a synchronous belt and a manufacturing method thereof. The synchronous belt includes a synchronous belt frame and a synchronous belt film wrapped outside the synchronous belt frame. The synchronous belt film is composed of the following raw materials in parts by weight: 40 ‑60 parts hydrogenated nitrile rubber, 10‑20 parts polyurethane elastomer, 5‑8 parts polycarbonate, 2‑5 parts ethylenevinyl acetate copolymer, 3‑5 parts polytrimethylene terephthalate, 4 parts -8 parts of γ-methacryloxypropyl trimethoxysilane, 2-4 parts of curing agent, 1-3 parts of anti-aging agent, 1-4 parts of lubricant. In the present invention, hydrogenated nitrile rubber, polyurethane elastomer, polycarbonate, ethylene-vinyl acetate copolymer, polytrimethylene terephthalate, etc. are used in combination to complement their performance, effectively improving the heat-resistant and wear-resistant properties of the synchronous belt. elasticity.

Description

technical field [0001] The invention belongs to the technical field of belt transmission, and in particular relates to a synchronous belt for belt transmission and a manufacturing method thereof. Background technique [0002] The synchronous belt is a new type of transmission belt whose working surface is a toothed structure, and the belt teeth are meshed with the gear teeth to transmit power. Synchronous belt drive combines the advantages of chain drive, belt drive and gear drive, and has the characteristics of accurate transmission, low noise, high efficiency, large speed ratio, no pollution, low energy consumption, compact mechanical structure, etc., and has a large transmission power range. [0003] Synchronous belt mainly includes synchronous belt film and synchronous belt skeleton. [0004] Early synchronous belts were made of cast polyurethane rubber, which has the advantages of general liquid rubber and does not require equipment such as rubber mixing and calenderin...
