Problems solved by technology

Existing double-sided united belts, such as the double-sided multi-V-shaped transmission belt with the patent No. 971813426 applied by the Goodyear Tire and Rubber Company of the United States, have solved the problem that the position of the groove in the longitudinal direction is easy to break, but the double-sided The combined belt needs to be equipped with a special pulley, its structure and volume are relatively large, and the scope of use is greatly affected by limitations
In the prior art, the special adhesive tape for rice harvesters disclosed in Patent Application No. 201110086161.3 uses aramid cord as the tensile material, which improves the impact resistance and transmission power of the adhesive tape; transverse short fibers are embedded in the primer to improve the adhesive tape. Adding short fibers to the surface glue increases the lateral rigidity of the tape and improves the transmission efficiency of the tape. However, due to the poor weather resistance of the rubber material and the large deformation of the belt body, there are still certain problems that cannot be achieved without maintenance. defect

Description

technical field [0001] The invention belongs to the technical field of transmission belt production, and in particular relates to an edge-cut double-sided transmission tooth-shaped combination belt. Background technique [0002] The transmission belt is an indispensable standard part in the mechanical transmission device. When used for long-distance or multi-wheel-train transmission, the existing combined transmission belt cannot realize multi-wheel-train transmission due to its structural limitation. At present, most of the edge-trimming joint belts produced by domestic manufacturers are in the form of one side. Existing double-sided united belts, such as the double-sided multi-V-shaped transmission belt with the patent No. 971813426 applied by the Goodyear Tire and Rubber Company of the United States, have solved the problem that the position of the groove in the longitudinal direction is easy to break, but the double-sided The combined belt needs to be equipped with a s...
