D-belt Category A, with a common core with a core common core is mostly belt with wire rope core, a small part of the use of cord with a core. Since both fiber with a core structure are twisted or establishment, in each belt operation between the fibers with a core shear leads to gradual elongation at break. Therefore, the use of wire rope core and ply belt with a common core production can only be applied in low-load transmission system. B, with a special core with a core of special belt with steel core using brown silk polyester polymer overall solid core rod with a core structure. Because brown silk polyester steel solid core untwisted structure as a whole, good adhesion, resistance to flex, high strength, long run, not only greatly improve the life of rubber belts, but with the body balanced life, companies can do maintenance, periodic replacement. November 22, 2010, brown polyester steel wire reinforcing materials identified by the Committee of Experts: brown silk with polyester steel belt as a reinforcing material with conventional polyester cord, hard rope, aramid fiber rope structural skeleton Material belts compared to 5-10 times the service life, an international advanced level. With a core of special belts effectively solve the high-load heavy horsepower transmission belts frequent replacement of ordinary problems, much favored heavy industry around the world.
