Problems solved by technology

[0003] During the use of V-ribbed belts, many problems have arisen in V-ribbed belts, such as: how to improve the transmission efficiency of V-ribbed belts, reduce the wear rate of V-ribbed belts, and reduce the noise during use; The V-belt is set on the pulley on the driving side and the driven side. During the transmission process, the contact area between the V-belt and the pulley is large, and the friction between the V-belt and the pulley is large. Compared with the V-belt, it can transmit higher power. , but this also leads to the noise produced by the V-ribbed belt, which limits its application
[0004] Chinese patent CN200880024509 discloses a V-ribbed belt, which has a wedge-forming surface, and the wedge-forming surface is formed with a plurality of wedges extending in the longitudinal direction of the belt. The noise generated by the wedge belt in water, but its structure is complicated, and the existence of the concave part reduces the contact area between the wedge belt and the pulley, so it is not suitable for transmitting high power, and the application range is not wide enough

Abstract

The invention relates to a noise-reducing and energy-saving EPDM polyrib belt which comprises a belt body made from an EPDM material. A group of trapezoidal wedges are arranged on the inner side of the belt body; a canvas layer vulcanized and adhered to the belt body is arranged on the outer side of the belt body, and the paving direction of the canvas layer is parallel to the transmission direction of the polyrib belt; a framework wound framework rope group along the transmission direction of the polyrib belt is arranged in the belt body, and the framework rope group is composed of an aramidfiber yarn and a hollow fiber yarn clinging to each other in parallel; the yarn diameter of the aramid fiber yarn is 0.7-0.9 mm, the yarn diameter of the hollow fiber yarn is 0.5-0.8 mm and the winding density of the framework rope group is 3-5 / cm. The noise-reducing and energy-saving EPDM polyrib belt not only has the characteristics of being long in service life and non-toxic and pollution-free, but also has the advantage of low noise in a using process.

Description

technical field [0001] The invention relates to an EPDM multi-ribbed belt, in particular to a noise-reducing and energy-saving EPDM multi-ribbed belt. Background technique [0002] As a transmission belt, the V-ribbed belt is widely used in the fields of engines, electrical appliances, compressors, etc. due to its advantages of small transmission vibration, fast heat dissipation, stable operation, small elongation in use and high limit line speed. [0003] During the use of V-ribbed belts, many problems have arisen in V-ribbed belts, such as: how to improve the transmission efficiency of V-ribbed belts, reduce the wear rate of V-ribbed belts, and reduce the noise during use; The V-belt is set on the pulley on the driving side and the driven side.
