BEAMLESS PUMPING UNIT WITH THE FOR OF THE ENGINE OUTPUT SHAFT ALIGNMENT DEVICE (OPTIONS) Russian patent published in 2018 - IPC F04B47/02 

FIELD: machine building.

SUBSTANCE: invention relates to the field of beamless pumping unit, more particularly to the beamless pumping unit with the motor output shaft leveling device. Beamless pumping unit includes frame, post and drive mechanism. Frame is rigidly attached to the ground. Post lower end is pivotally connected to the frame. Tie-rod connects the post and frame. Tie-rod two ends are pivotally connected to the post and to the frame, respectively. Post and frame hinged connection point and the tie-rod two end points together form a triangular support structure. Post upper end is equipped with a platform. Platform has a drive mechanism, including engine, large roller, small roller, belt and the counterweight device. Engine is connected to the large roller by means of chain and sprockets. Belt one end is connected to the balance beam suspension. Other end hangs down after wrapping around the large roller and small roller on the upper side and is connected to the counterweight device. Engine output shaft end is equipped with the shaft end alignment mechanism. Shaft end alignment mechanism includes leveling support A, adjustment support, and adjustment screw A.

EFFECT: increase in the mechanical transmission efficiency, reduction in the energy consumption, reduction in the maintenance difficulty and failure rates.
