The utility model relates to an adaptive double crank flexible transmission pumping unit, which mainly solves the problems that the existing pumping unit has the advantages of excessive power transmission links, motor output power and big torque fluctuation of the speed reducer, resulting in low system efficiency. It is characterized in that both ends of the output shaft of the reducer is respectively connected with a crank, a crank wheel crank are respectively fixed on both sides of the box body, wherein are respectively fixed with the slider stroke adjusting mechanism, the upper part of the box body are respectively fixed with a slide chute, one end of a positioning wheel, between the beams which can slide along the both ends of the flexible beam around the pumping rope and the other end of the crank roller after stroke adjusting slider mechanism connected with the middle part of the beam pumping derrick flexible positioning rollers around the upper part of the bracket wick wellhead connection after oil extraction equipment. The adaptive double crank flexible drive pumping unit reduces the intermediate transmission link, reduces the motor output power and the torque suffered by the reducer, and improves the system efficiency.
