Abstract

The invention discloses a hydrogenated nitrile butadiene V-ribbed belt for an engine. The hydrogenated nitrile butadiene V-ribbed belt aims to overcome shortcomings that an existing V-ribbed belt is narrow in service temperature range and is short in service life when used at temperature exceeding the service temperature range. The hydrogenated nitrile butadiene V-ribbed belt for the engine sequentially comprises a back cloth layer, an adhesion layer and a compression layer from outside to inside, a framework layer is distributed in the adhesion layer, a plurality of wedge grooves are arranged on the inner surface of the compression layer, both the adhesion layer and the compression layer are mainly made of hydrogenated nitrile butadiene rubber, and base cloth of the back cloth layer is mainly made of rubber cement of hydrogenated nitrile butadiene rubber by means of immersion treatment. The hydrogenated nitrile butadiene V-ribbed belt for the engine can normally and effectively work within a wider temperature range from -50 DEG C to 150 DEG C for a long time, and is stable in performance and long in service life.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a hydrogenated nitrile butadiene rubber V-ribbed belt for an engine. Background technique [0002] Hydrogenated nitrile rubber V-ribbed belts are widely used in automobile engines. As the space of automobile engines becomes smaller and smaller, the power increases, the operating conditions become increasingly harsh, and the operating temperature becomes higher and higher. longer and longer. The V-ribbed belt materials currently used are mostly neoprene or EPDM rubber, the effective use temperature range of neoprene rubber is -30℃~100℃, and the effective use temperature range of EPDM rubber is -40℃~ 120°C, beyond this temperature range, the service life of the V-ribbed belt will be greatly reduced. At the operating temperature of -50°C, these two types of belts have lost their elasticity, and the service life is only about 20 hours. Therefore, most outdoor high-power equip...
