Abstract
The utility model relates to an oil pumping machine, which is used for pumping crude oil in an oil well. A lifting flexible cable crosses through a big pulley which is arranged at the upper part of a main beam, one end of the lifting flexible cable is connected with a vibration absorber and a sucker rod, and the other end of the lifting flexible cable is connected with a vibration absorber which is arranged on a balance weight. The lower part of the balance weight is connected with a reverser which is connected with a chain through a special chain link. A rolling wheel is arranged in a long groove of the reverser. A driving chain wheel and a driven chain wheel are engaged with the chain. Both sides of the balance weight are respectively provided with a guide wheel which is contacted with an upright post of the main beam. A bearing unit is connected with a shaft coupling, a speed reducer, and a transfer case. An input shaft of the speed reducer is connected with an input shaft of the transfer case. The utility model has the advantages of high efficiency, low energy consumption, adjustable stroke, and adjustable times of the stroke.
