Industrial belts are classified into three categories: industrial transmission belts, automotive transmission belts and conveyor belts.The first two are all transmission belts.Transmission belts are used to transmit mechanical power, including flat transmission belts and triangular transmission belts (V-shaped belts).Composed of rubber and reinforced materials (such as cotton canvas, rayon, synthetic fiber or steel wire, etc.).It is made of multi-layer rubberized canvas, synthetic fiber fabric, cord and steel wire as the tensile layer, which is covered with rubber and then formed and vulcanized.Compared with gear transmission and chain transmission, belt transmission has the advantages of simple mechanism, low noise and low equipment cost, and is widely used in various power transmissions.The endless belt that is driven on the machine is sheathed on two pulleys and is mostly made of cowhide or thread core rubber, which is generally called a belt.

The transmission belt is the power generated by the rotation of the motor or engine of the prime mover, which is transmitted to the mechanical equipment by the belt through the pulley, so it is also called the power belt.It is the core connecting component of electromechanical equipment, with an unusually wide variety and a wide range of uses.Transmission belts are inseparable from giant motors of several kilowatts to micro motors of less than one kilowatt, and even precision machinery such as household appliances, computers, and robots.Its biggest feature is that it can freely change the speed, drive near and far, simple structure and easy to replace.Therefore, from primitive machinery to modern automatic equipment, there are transmission belts. The products have undergone many changes and the technology has become more mature.

Transmission belts can be divided into V-belts, timing belts (toothed belts, timing belts), flat belts (base belts, dragon belts), agricultural belts, high-speed oil-proof belts, round belts (round belts), flat belts, water towers Belts (wide-angle belts), variable-speed belts, motorcycle variable-speed belts, V-belts (V-belts), parallel belts, multi-groove belts, hexagonal belts, flexible belts, traction belts, automobile belts.

Conveyor belts are widely used in cement, coking, metallurgy, chemical, steel and other industries where the transportation distance is short and the transportation volume is small.The conveyor belt is made of multi-layer rubberized cotton canvas as the skeleton, and a rubber material with good surface covering performance is made by vulcanization.All conveyor belts must be connected in a ring shape to be used, so the quality of the conveyor belt joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly.Commonly used methods for conveyor belt joints include mechanical joints, cold-bonded joints, and hot-vulcanized joints.

Conveyor belt with ordinary cotton canvas conveyor belt, nylon (NN) conveyor belt, polyester (EP) conveyor belt, large inclination (corrugated rib) conveyor belt, skirt partition conveyor belt, endless conveyor belt, pattern conveyor belt, stop Water belt, PVC or PVG whole core flame retardant belt and various special performance conveyor belts (general flame retardant conveyor belt, heat resistant conveyor belt, burn resistant conveyor belt, high wear resistant conveyor belt, acid resistant conveyor belt, alkali resistant conveyor Belt, cold resistant conveyor belt, oil resistant conveyor belt, high temperature resistant conveyor belt, high strength conveyor belt and food conveyor belt).According to the tensile strength of the conveyor belt cloth layer, it is divided into ordinary conveyor belts and powerful conveyor belts.The powerful canvas conveyor belt is divided into nylon conveyor belt (NN conveyor belt) and polyester conveyor belt (EP conveyor belt).
