As we all know, there are some general types of belts. In addition to flat belts and timing belts, V Belt and film belts also have many features and applications. V belt, is a cross-section for the trapezoidal ring belt collectively, sub-special belt with a V-belt and ordinary V-belt two categories. Compared with the flat belt, with easy installation, small footprint, high transmission efficiency and low noise, etc., in the entire transmission area occupies an important position.

V-belt is the basic power transmission type, providing the best combination of traction, running speed, bearing load and service life. They are generally endless and have a trapezoidal cross-section that extends in a pulley having a V-shaped groove. Their wedging action in the pulley groove allows them to transfer higher torque at a smaller width and tension than flat.

They are far superior to flat belts in the case where the center distance is small and the reduction ratio is high. Because of their larger thickness, they require larger pulleys than flat belts. When the transmitted power exceeds the power of a single conveyor, several separate belts running on the same pulley in a separate slot are usually used. These are called multi-band drives. When the ring belt does not meet the needs, you can use to connect and connect the belt. The connecting V-belt is made of metal fasteners that are secured together by a number of rubber fabrics. They can adjust the length by disassembling and removing the links.

Film belts are usually classified as a variety of flat belts, but in fact they are of a separate type. They consist of a very thin belt (0.5-15 millimeters or 100-4000 microns) strip of plastic and occasionally rubber. They are typically used for low power (10 hp or 7 kW), high speed applications, enabling high efficiency (up to 98%) and long life. Which can be seen in commercial machines, tape recorders and other light operations.

All the different types of belts have their own characteristics. They can find their own functionality during the application. Of course, this is the same as the above type. Although they have many shortcomings, their advantages outweigh their disadvantages. Therefore, they are still very important in many industries.
