Power belts have been used for more than 200 years. At the beginning the driving belt was flat and run on the horizontal sliding wheel. Later, cotton ropes or hemp ropes and V groove pulleys gradually entered the scope of use, and their use greatly reduced the belt tension. Since 1917, the V belt has gradually been in the public eye.
Today, flat belts and V belts are still widely used in power transmission. Compared with other forms of power transmission, belt drive provides a more flexible choice. It has advantages of low cost, simple installation and maintenance. The most important thing is its relatively low price. These advantages make it attract a large number of faithful users. The difference between flat belt and V belt is as follows:
The biggest advantage of the V belt is the function of wedging into the pulley groove. V belts are usually used in industrial applications. They are relatively low-cost, easy to install, and have a wide range of sizes. The toothed structure of the V belt makes it easier for the fast-moving belt to be fixed in the pulley groove instead of simply being held on the pulley like the flat belt. And the flat belt materials are various.
Although the surface of the flat belt is relatively smooth and does not have a toothed structure like the V belt, the surface of different flat belts will also have different patterns, which can meet different drive requirements. In high-horsepower applications and outdoor installations, flat belts have longitudinal grooves on the surface. The presence of these longitudinal grooves not only reduces the friction between the pulley and the belt, but also almost eliminates the influence of dirt, dust, oil and grease and helps to reduce the noise when flat belts are running.
