Problems solved by technology

However, the glass fiber rope also has many disadvantages, such as brittleness, intolerance to twists and turns, and poor stability to impact loads, resulting in reduced reliability of the synchronous belt.
[0006] The general lifespan of the existing synchronous belt is not long enough, the main reason is that the temperature is too high under the condition of high-speed operation, and the heat resistance of the material needs to be improved.

Abstract

The invention discloses a novel synchronous belt. The synchronous belt comprises a synchronous belt skeleton, a synchronous belt film wrapped outside the synchronous belt skeleton and a synchronous belt wrapping cloth layer. The synchronous belt film is made of 25-30 parts of Rubber, 35-55 parts of hydrogenated nitrile rubber, 10-20 parts of LCP plastic raw materials, 3-5 parts of dicyclopentadiene, 4-6 parts of polyoxymethylene, 5-8 parts of SEBS, 2-5 parts of ethylene-acetic acid Ethylene copolymer, 4-8 parts of γ-methacryloxypropyl trimethoxysilane, 2-4 parts of curing agent, 1-3 parts of anti-aging agent, 2-4 parts of lubricant. The present invention uses butadiene rubber, hydrogenated nitrile rubber, LCP plastic raw materials, dicyclopentadiene, polyoxymethylene, ethylene-vinyl acetate copolymer, etc. to complement each other in performance, and improves the manufacturing process of the synchronous belt, effectively Improve the heat resistance and wear resistance of the synchronous belt and increase its service life.

Description

technical field [0001] The invention belongs to the technical field of belt transmission, in particular to a novel synchronous belt for belt transmission. Background technique [0002] Synchronous belt transmission is a transmission mode developed by combining the advantages of belt transmission and gear transmission on the basis of chain transmission, and has the advantages of belt transmission, gear transmission and chain transmission. The outstanding advantages of synchronous belt transmission are: the belt and the pulley are strictly synchronized, there is no relative slip, which ensures an accurate transmission ratio; the backlash is small; the pre-tightening force is small, the load on the shaft and bearing is small; the unit length of the belt is small. , high allowable line speed; high transmission efficiency; good shock absorption capacity, stable transmission, low noise; compact structure, good wear resistance, no maintenance and lubrication, etc. Because synchron...
