V Belt classification and widely used.
The v belt is also known as double-sided V belt, which is a kind of product of production *, variety * and use * widely used in transmission belt.In the world's belt, the triangular belt now accounts for 65 percent of the total amount of rubber used, and the toothed belt is 25 percent, and the belt has been reduced to less than 10 percent.Triangle has become the world's all kinds of mechanical power transmission and variable speed of main equipment, in the modern agricultural machinery, machine tools, automobiles, ships, office equipment, such as wide range, is playing an increasingly important role.
1. Classification according to section size.
The triangle belt can be divided into two categories: Y, O, A, B, C, D, E, and various fan belts used by automobiles and tractors.Y, O type is * small v-belt, mainly used for typewriter, book cutting machine and other office equipment, household appliances (washing machine, juicer, vacuum cleaner).In general industrial machinery, with the increase of horsepower, A, B, C, D, E and other v-shaped belts are used in order, among which D and E are heavy belts, which are used for large machinery such as ships and electric power.As for the fan belt, besides cars and tractors, it is also used in water pump and air conditioning.In developed countries, the production ratio between the triangle belt and the fan belt has reached the level of 2:1 to 3:2, and the fan belt shows a significant increase.
2. V-shaped belt of v-belt.
The triangle belt generally refers to the package type v-belt, which is to improve the durability of the belt, and also has the cutting edge v-belt.This kind of cutting edge v-belt, because the belt structure is not covered by the fabric, the belt is very soft, the flexural fatigue performance is very good, and thus the rapid development.To solve the triangle dogan group drive with the produce is not the same as the transmission efficiency and service life is long and fell, and rise the more root triangle triangle together with flat belt.It is known as the v-type flat belt of the group triangle, which is of great advantage. Therefore, the v-type flat belt is replaced by the phenomenon of the bag type and the cutting edge triangle.This triangle and flat belt with adhesive tape, although there are special requirements on the pulley groove, however, because the body is very thin, and the pulley contact area is large, good bending, pulley, can make the actuator further miniaturization, energy conservation, production increase sharply in developed countries of the world.
