V-belt kit replaces Volvo 9523857 Bus 9/11/12/13 (D/DH engine)

The triangle has two kinds of special belt core structure and rope core structure, which are respectively composed of four parts: cloth covering, top rubber, tensile body and bottom rubber. The V-belt with the rope core structure is convenient to manufacture, the tensile strength is general, the price is low, and it is widely used. The V-belt with the special core structure has good toughness and high strength, and is suitable for occasions with higher speeds.

Ordinary core

Most of the cores of the ordinary V-belt with core are cord cores, and a small part of them are cord fabric cores. Since these two core structures are fiber twisted or woven, the inter-fiber shearing during the operation of the V-belt causes the core to gradually break and elongate. Therefore, ordinary V-belts produced with cord cores and cord cores can only be used in low-load transmission systems.

Special belt core—polyester tempered brown ribbon core

The belt core of the special belt core triangle belt adopts the whole solid rod-shaped belt core structure of polymer polyester tempered brown wire. Because the polyester tempered brown wire is an integral solid core and untwisted structure, it has good adhesion, flex resistance, high strength, and does not run long. It not only greatly improves the service life of the rubber transmission belt, but also has a balanced service life. It is maintenance-free and replaced regularly. On November 22, 2010, the polyester tempered brown wire skeleton material passed the appraisal of the expert committee: using polyester tempered brown wire as the skeleton material of the transmission belt and traditional polyester soft rope, hard rope, aramid and other fiber rope structure skeleton Compared with the material transmission belt, the service life is increased by 5-10 times, which is the international leading level. The special belt core transmission belt effectively solves the frequent replacement of ordinary transmission belts in the high-load and heavy-horsepower transmission system, and is highly favored by heavy industry enterprises all over the world.
