introduction：Colpate zone（Multigrain tape，Wedged belt）It refers to the flat belt as the matrix、The inner surface is arranged longitudinally with equal spacing40°Trapezoidal wedge ring rubber belt，The working face is the side of the wedge。 advantage： The contact area and friction between the multi-wedge belt and the pulley are larger，The load is evenly distributed along the bandwidth，Thus the transmission capacity is greater；Because the belt body is thin and light、Good flexibility、Reasonable structure，So the working stress is small，Works on smaller pulley；The multi-wedge belt also has low transmission vibration、Radiate quickly、Smooth running、Low service elongation、Large transmission ratio and high limit linear speed，And therefore live longer；Obvious energy saving effect，High transmission efficiency；Compact drive，Take up little space。In addition，The back of the multi-wedge belt can also drive，An automatic tension regulator is also available，Make the transmission safer、reliable。The multi-wedge belt is especially suitabl

introduction：Triangular beltThere are two kinds of special belt core structure and rope core structure，Respectively by wrapping cloth、Rubber bushing、The tensile body and the substrate are composed of four parts。 The triangle belt with rope core structure is convenient to manufacture，The tensile strength is average，Low price，Widely used The triangular belt with special core structure has good toughness，High strength，Suitable for high speed applications。 Classification introduction： 1、Plain core： Most of the common core with core triangle belt adopts the cord core，A few use cord core。Because these two core structures are fiber twisting or weaving，In the operation of the triangular belt, the fibers shear each other, resulting in the gradual fracture and elongation of the core。therefore，The common triangle belt made of cord core and cord core can only be used in low-load transmission system。
