Type of transmission belt? Pictures? And the characteristics of each kind of belt?
3. round belt. The circular belt is a circular belt with a round profile, which can be freely bent and driven. The belts are mostly made of polyurethane and usually have no core body, the structure is the most simple and the use is convenient. The circular belt has opened up a new way for belt transmission, and the amount of consumption in small machine tools, sewing machines, precision machines and other fields all over the world is increasing rapidly, and the potential is very great in the future. 4. gear belt. The toothed belt, also called synchronous belt, is divided into two types, one side toothed belt and two sided toothed belt. The former is mainly used in single shaft transmission, the latter is multi axle or reverse transmission. It is another new type of high efficiency transmission belt emerging from the world since 1980. The toothed belt is divided into two kinds of trapezoid and arc shapes according to the shape of the tooth, and the torque is the largest with the synchronous belt of the circular tooth. From the materials used, the toothed belt can be divided into rubber and polyurethane two major categories, while the former and ordinary rubber (usually chloroprene rubber) and special rubber (mostly saturated nitrile rubber) points. The structure is composed of steel cord or glass fiber and is made of rubber or nylon cloth. Hope to help you, hope to adopt!
As the flat belt drive efficiency is low (usually about 85%), and occupies a larger area, therefore, from 1960s, the world's output has dropped year by year. At present, in developed countries, in addition to some agricultural machinery and textile machinery is still a small amount of use, has been in a state of being eliminated. On the other hand, in this period, the non - joint and hot - junction ring made of chemical fiber canvas and cord fabric became a great progress all over the world. With high strength, low noise, stable transmission, smooth transportation, flex, long life and no joint features such as, using the field continues to expand, and in the micro belt formed in the mainstream. 2. triangle belt: (1) narrow and wide v-belt. (2) small angle and big horn triangle belt. (3) flexible and punched v-belt. Triangle belt, also known as V belt, is the largest output belt, the most varieties and the most widely used products. Since 1917, the first American made car fan belt, after the early 20s began to spread to the agriculture machinery, more than half a century of development is very rapid, has become the mainstream of the drive belt. In the world's transmission belt, from the rubber consumption point of view, the triangle belt has now accounted for 65%, the tooth belt is 25%, flat belt has been reduced to less than 10%. At present, V-belt has become the main equipment of power transmission and speed change in various mechanical devices in the world. It plays a more and more important role in the fields of agricultural machinery, machine tools, automobiles, ships, office equipment and so on.
The varieties of the belt are classified as follows: 1. flat belts. The flat belt is one of the oldest varieties of transmission belt. It has more than 100 years of history, but it still accounts for about half of the market share in the transmission belt until the middle of twentieth Century. The utility model has the advantages of simple structure, convenient transmission, no limit of distance, easy adjustment and replacement, etc., and is widely used in various industrial and agricultural machinery. Flat belt width is generally 16-600mm, the length of the maximum up to 100 ~ 200m, the number of layers is 6, the most common for the canvas belt, divided into cladding, stacked and stacked three. Laminated tape (also known as the cladding with round edge band) improved products, with soft, elastic, durable advantages such as flexible, suitable for use in small round and above 20m/s fast transmission device. The folded belt is between the two, and is easy to wear at the edges
