The common conveyor belt are triangular belts. The triangle has two kinds of special 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, has general tensile strength, and is low in price. It is widely used. The V-belt with special core structure has good toughness and high strength, and is suitable for occasions with high speed.

The reference length of the V-belt is as follows: When the V-belt rotates and bends around the pulley, the layer whose length and width remain unchanged is called the neutral layer. Under the specified tension, the circumference measured along the neutral layer of the triangle belt is called the reference length, also called the nominal length. It is mainly used to calculate the geometric size of belt transmission and mark the triangle belt, and its length has been standardized. In addition, the length of the domestic V-belt is also expressed by the inner circumference and outer circumference.

In addition, the hexagonal belts are also one of the common products.
