Problems solved by technology

However, because multiple sets of transmission belts work side by side, the work load and torque they bear are relatively large. Due to the structural design of the belt body, the existing combined belts have the problems of being unable to meet high-intensity work and having a short service life.
[0004] There is a stretch-resistant combined belt on the market, the connecting layer includes an outer layer, a middle layer and an inner layer connected in sequence, the inner layer is connected to the belt, the first composite metal mesh is set between the inner layer and the middle layer, and the middle layer and the outer layer A second composite metal mesh is arranged between them, and a plurality of horizontal high-toughness tensile wires and longitudinal high-toughness tensile wires arranged side by side are evenly embedded on the middle layer, and the horizontal high-toughness tensile wires and the longitudinal high-toughness tensile wires are perpendicular to each other; The composite metal mesh increases the tensile strength of the ganged belt, but also increases the internal bending stress of the ganged belt during operation, which leads to cracks easily appearing inside the connecting layer and reduces its service life

Abstract

The invention relates to a joined E-belt. The joined E-belt comprises a connection layer and three V-belts which adhere to the connection layer through vulcanization; the connection layer is composedof an inner anti-tear rubber layer and an outer flexible polyester-mixed cotton cloth layer, and the anti-tear rubber layer and the flexible polyester-mixed cotton cloth layer are bonded through vulcanization; the anti-tear rubber layer is 2.5-4.5 mm thick, and the flexible polyester-mixed cotton cloth layer is 0.3-0.6 thick; each V-belt is composed of a rubber matrix and a framework arranged in the rubber matrix, the framework is formed by winding HMLS polyester fiber cotton ropes in the circumferential direction of the V-belt side by side, the diameter of the HMLS polyester fiber cotton ropes is 0.6-1.0 mm, and the winding density is 6-9 ropes per centimeter. The joined E-belt suitable for large-power transmission has the advantages of being high in strength, low in operation noise and long in service life.

Description

technical field [0001] The invention relates to the technical field of rubber transmission belt production, in particular to an E-type combined belt. Background technique [0002] The V-belt is the most widely used transmission belt in the transmission belt. The V-belt transmission relies on the friction force generated by the pressure between the two sides of the V-belt and the side of the wheel groove for power transmission; the V-belt relies on its advantages of compact transmission structure and large transmission power. And widely used in various mechanical equipment. [0003] The combined V-belt is a V-belt group formed by connecting several V-belts through the connecting layer. The combination of V-belts can make the vibration of the V-belts cancel each other through the connecting layer, and the combination can endow each V-belt with lateral rigidity and stability, thereby eliminating the vibration phenomenon of each single root. In addition, the combined V-belt ha...
