Rubber V Belt For Industrial Application And Auto , High Strength Wear Resistant



V belts are a type of belt than run in a pulley with a V-shaped grooved. Typically endless, V belts contain a trapezoidal cross section. Compared with flat belts, V belts transmit higher torque at lower levels of tension and width. V belts are one type of conveyor belting that fits various applications.

Prevent the selection of matching triangular belt for belt pulley with series groove installation


The triangular belt is a rubber belt component used in mechanical equipment such as engines to transmit mechanical energy. Almost all mechanical equipment can not leave the transmission of the triangle belt. In order to protect the performance of the triangle belt, its manufacture is divided into many layers.


1. Rayon and rayon fabrics are soft to the touch, breathable and comfortable to wear, and brightly colored.


2. Man-made fiber fabric has good hygroscopic properties, and its hygroscopic properties are better in chemical fiber. But its wet strength is very low, it is about 50% of dry strength only, and fabric shrinkage rate is bigger, therefore should shrink in advance before cutting had better.


3, triangle belt manufacturers of ordinary viscose fabric with good drape, stiffness, resilience and wrinkle resistance of the characteristics of poor, so its poor garment shape, easy to produce wrinkle.


4. Viscose fiber fabric has good acid and alkali resistance, sunlight resistance and other drug resistance.
