But the structure of the belt also determines that the belt has certain defects that the belt is easy to deform and extend in the running process, so that the belt body and the belt wheel generate relative displacement, and the belt body is subjected to sliding friction and heat generation to cause premature failure and damage of the belt body. In the initial stage of oil field exploitation, it is used in large quantity. However, as the depth of crude oil production is increased, from about 1000 meters to over 3000 meters at present, and the number of horizontal wells and thick oil wells is increased, the load of the oil pumping unit is increased. Therefore, the deformation of the connected narrow V-belt is increased, the friction force between the V-belt and the belt wheel is reduced, the transmission efficiency is reduced, and the V-belt is slipped and heated and even burnt.

Compared with the prior art, the V-belt outer cloth layer manufactured by the cloth adhesive has the advantages that the friction coefficient of the V-belt outer cloth layer manufactured by the cloth adhesive and the belt wheel is improved to 0.48 from 0.36, and the relative displacement between the belt body and the belt wheel is greatly reduced. The bearing capacity of the belt body is improved by laying two strong layers. The top strong layer applies larger pressure to the belt body in the running process so that the friction force between the belt body and the belt wheel is improved, and the transmission efficiency is improved. Increase bottom width and make the area body be unlikely to too much to be absorbed in the groove of band pulley under big pressure, guaranteed that area body length can not take place big change to prevent that the drive belt from skidding. The transmission belt is matched with 9J, 15J and 25J belt wheels used by the existing oil pumping unit, so that the oil pumping unit does not need to replace the belt wheels, thereby saving a large amount of funds for users. The production of the transmission belt can partially adopt the production process and equipment of the wrapping belt, has small production investment, and can solve the problems of low bearing capacity, easy slipping, low transmission efficiency and short service life of the original combined narrow V-belt.
