Problems solved by technology

However, under the existing processing conditions, the strength and elasticity of the synchronous belt made of HNBR rubber are low, and there are inevitably microscopic defects such as microcracks, impurities, and microvoids inside; and the shear strength and High temperature resistance and wear resistance are not ideal, which may easily lead to problems such as tooth loss, tooth deformation, transmission power and service life reduction

Abstract

The invention relates to a high-strength synchronous belt. The synchronous belt comprises a synchronous belt framework and an adhesive piece attached to the outer side of the synchronous belt frame. The adhesive piece comprises the following components in parts by weight: 70-90 parts of hydrogenated butadiene-acrylonitrile rubber, 10-30 parts of chloroprene rubber, 14-25 parts of trans 1, 4-polyisoprene, 4-8 parts of methylacryloyl silane, 5-15 parts of aramid pulp, 10-20 parts of reinforced fiber SP-6701, 20-40 parts of carbon black, 4-7 parts of peroxide crosslinking agent, 1-4 parts of assistant crosslinking agent, 0.5-1.5 parts of hexamine, 2-5 parts of plasticizer and 1-3 parts of antiaging agent. The invention also relates to a manufacturing method of the synchronous belt. According to the high-strength synchronous belt and the manufacturing method thereof, the hydrogenated butadiene-acrylonitrile rubber and the chloroprene rubber are used together, so that the performances of the hydrogenated butadiene-acrylonitrile rubber and the chloroprene rubber are complementary, and thus the wear resistance and the heat resistance of the adhesive piece of the synchronous belt can be effectively improved; the shear strength and the quality stability of the synchronous belt are improved by use of the trans 1, 4-polyisoprene, the methylacryloyl silane and the aramid pulp.

Description

technical field [0001] The invention relates to the technical field of synchronous belts, specifically a high-strength synchronous belt with good mechanical properties, and also relates to a preparation method of the high-strength synchronous belt. Background technique [0002] The synchronous belt is an endless belt with equally spaced teeth on the inner peripheral surface. When rotating, the power is transmitted through the meshing of the belt teeth and the gear teeth. The synchronous belt combines the advantages of belt drive, chain drive and gear drive, and has the advantages of high transmission efficiency, accurate transmission ratio, large transmission ratio range, stable transmission, small force on the shaft, low noise, and energy saving. [0003] The main body of early synchronous belts was mostly made of polyurethane rubber. Polyurethane rubber has the advantages of general liquid rubber, good wear resistance, simple process, and convenient molding. However, polyu...
