In order to solve the problems, the invention is realized by the following scheme: a transmission belt for an oil field pumping unit comprises a covering layer, a strength layer, a buffer layer, a cloth wrapping layer and a glue layer, wherein the covering layer, the upper strength layer, the upper buffer layer, the cloth wrapping layer, the tensile glue layer, the lower buffer layer, the lower strength layer and the compression glue layer are respectively arranged from the outside to the inside of the transmission belt; the covering layer and the upper buffer layer are bonded into a whole, the upper strength layer is a cylindrical reinforcing rib, and the upper strength layer is uniformly distributed in the upper buffer layer; the outside of the combined V belt is wrapped with a cloth wrapping layer, and the cloth wrapping layer and the upper buffer layer are bonded into a whole; the upper portion of ally oneself with group V area sets up to stretch the glue film, and the lower part is the compression glue film, is lower buffer layer between stretch the glue film and the compression glue film, and lower strength layer is cylindrical strengthening rib, evenly arranges in buffer layer down.
A gap is formed between the two groups of the V-shaped belts, the gap is 0.6-2.7 mm, and the base angle of the V-shaped belts is 40 degrees.
The width of the bottom of the belt body is increased by 0.8-0.5mm compared with the maximum opening of the corresponding belt wheel, and the other sizes of the belt body correspond to the connected narrow V-shaped belts 9J, 15J and 25J.
The covering layer is generally made of canvas.
Compared with the prior art, the utility model has the advantages that the coefficient of friction of the V area outsourcing cloth layer that uses this kind of cloth to glue the preparation and band pulley improves to 0.48 by original 0.36, the relative displacement greatly reduced between the area body and the band pulley. 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.
