Impeller Belt

The propeller belt is actually a type of power transmission belt that is used in most industrial machines that work with an internal combustion engine. The propeller belt is used in gasoline or diesel engines to drive the cooling propeller that is placed behind the engine radiator system. Impeller belt تسمه پروانه is used both in ribbed form similar to timing belts, as well as grooved in the longitudinal direction of the belt and in many cases V-belt type. In the first two cases, i.e. in the case of having ribs or grooves, the impeller belt can be unidirectional, i.e. it has ridges and grooves only inside the rib, or in some cases, it can be produced as a double impeller belt, which has ribs or grooves on both sides.

Polymer compounds are often used in the production of propeller belts to have high tensile, thermal and abrasion capabilities in addition to high flexibility. The process of replacing polymer instead of leather and fabric belts took place from 1875 to 1925, which became possible with the access of more and more people to modern technologies in the production of strong polymer compounds. The most widely used type of polymer in the production of propeller belts of combustion engines is polyurethane PU. Of course, due to its high flexibility, polyurethane alone does not have the capabilities required for the performance of the propeller belt تسمه صنعتی, and to increase resistance to creep on the one hand and resistance to friction and wear on the other, it must be strengthened by using additives.
