Agricultural machine belt of meridian cord fabric structure

Abstract

The invention provides an agricultural machine belt of a meridian cord fabric structure. The agricultural machine belt comprises a wrapping fabric layer circumferentially wrapping the outer portion of an agricultural machine belt body, top glue, a strength layer, buffer glue, meridian cord fabric layers, compression glue and bonding glue used for bonding the meridian cord fabric layers and the compression glue. The top glue is bonded to the position above the strength layer. The buffer glue is bonded to the position below the strength layer. The compression glue circumferentially wrapped by the meridian cord fabric layers is bonded to the lower portion of the buffer glue. The large top of the compression glue is wrapped by the two meridian cord fabric layers. Meridian cord lines in the meridian cord fabric layers are arranged in parallel, and an included angle between each meridian cord line and the center line of the agricultural machine belt body is 90 degrees. By the adoption of the agricultural machine belt of the meridian cord fabric structure, the transverse rigidity of the agricultural machine belt is improved, the load capacity of the agricultural machine belt is improved, and a transmission belt is prevented from deforming in the use process; a compression glue reverse-wrapping technology is adopted by meridian cord fabric, a cord fabric press seam is in lap joint with the large face of the compression glue, and the transverse rigidity and the bearing and pressure measuring capacity of the belt body can be better improved through the two cord fabric layers on the compression glue.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to an agricultural machinery belt with a meridian cord structure. Background technique [0002] Agricultural machinery belts refer to transmission belts used in agriculture, horticulture and forestry operations. Their varieties and specifications include almost all V-belt varieties and a small amount of flat belts and special-shaped belts. The most important one is the stepless belt for combine harvesters. speed belt. The use of continuously variable speed belts for agricultural machinery is characterized by large alternating loads during use, large starting loads, low speeds and high loads, high impacts, extreme stretching, compression deflection, and skidding to generate heat, and the working environment is harsh (sun and rain) , sediment dust and oil stains, etc.) often occur during the use of the bottom rubber breakage, affecting the overall service life of the ...

AI Technical Summary

Problems solved by technology

[0005] The cord reinforcing layer described in the above-mentioned patent uses a cord of general weaving structure, which not only strengthens the transverse rigidity of the V-belt, but also increases the longitudinal rigidity, which affects the dynamic flexibility of the V-belt circumferential transmission, thus making the belt in the transmission During the process, the bending stress increases and the heat generation increases; at the same time, the reinforcing layer is arranged at the lower part of the compression rubber. Since the lower part of the compression layer is subjected to the largest compression deformation on the pulley, the increase in the rigidity of the lower part will easily increase the heat generation of the V-belt during use, and compression Uneven stress on the rubber, etc., is prone to cracks, and even causes the curtain and rubber to fall off

In addition, if the lower rigidity of the buffer rubber has not been improved, it will still cause the belt body to sag and deform when the V-belt is pulled, and the tensile body cannot be kept at the same level during use, which affects the overall strength of the V-belt, thereby affecting V-belt service life
