Embodiment Construction

[0013] From the drawings, the planetary gear pumping unit is composed of a base, a frame, a motor, a support, a gear box, a sun gear shaft, a reduction gear, a planetary gear shaft, a speed gear, a ring rack, a suspension system and a system. composed of moving devices. It is characterized in that: a support 6 is installed in the middle of the frame 2, a gear box 7 is installed on the support 6, a sun gear shaft 9, a reduction gear shaft 15 and a planetary gear shaft 10 are installed on the gear box, the reduction gear shaft 15 and the planetary gear shaft 10 are equipped with a reduction gear 20, 21. Among them, the sun gear shaft 9 meshes with the reduction gear 20 on the reduction gear shaft 15, and the reduction gear shaft 15 meshes with the reduction gear 21 on the planetary gear shaft 10. The gear shaft 10 meshes with the ring gear 4. A reversing guide wheel 11 is installed at one end of the planetary gear 10. Since the two ends of the ring rack 4 are semicircular long r...

Abstract

The invention discloses a planet gear ring oil pumping unit comprising a rack, a motor, a support, a gear box, a sun wheel gear shaft, a planet gear shaft, speed reduction gears, an annular rack and a rope suspending system. The planet gear ring oil pumping unit disclosed by the invention is characterized in that the middle part of the rack is provided with a support, the support is provided with the gear box, the gear box is provided with the sun wheel gear shaft, the speed reduction gear shaft and the planet gear shaft, and the speed reduction gear shaft and the planet gear shaft are respectively provided with one speed reduction gear. The planet gear shaft is meshed with the annular rack and does linear movement, and the two ends of the rack are semi-circular long rings, so that the oil pumping unit operates to an annular gear surface and enters into a guide ring, a planet gear is meshed with a semi-circular gear and moves from the left side of the rack to the right side of the rack under the action of the guide ring, the annular rack starts to operate in an inverted manner at the moment, reciprocation of the rack is realized, the rope suspending system at the top of the rack is driven, and the aim of pumping oil is achieved. The planet gear ring oil pumping unit disclosed by the invention has the characteristics of simple structure, reliable operation, high efficiency, stable reversing, economical efficiency and durability.

Description

technical field [0001] The invention relates to the field of petroleum oil recovery mechanical equipment, in particular to a planetary gear ring pumping unit (hereinafter referred to as a gear ring pumping unit). Background technique [0002] At present, oil production in oilfields is the traditional beam pumping unit. Although it has undergone various improvements and has the characteristics of durability, its motion principle remains unchanged, and there are still disadvantages such as high energy consumption. The patent number is: 200920019023.1 long ring rack pumping unit and the patent application number is: 200910020560.2 inclined elongated rack pumping unit, which adopts a small gear unidirectionally meshing with a ring rack for reciprocating linear motion, Drive the rope to lift the sucker rod up and down through the pulley. In order to prevent the pinion from being repelled when it meshes with the rack, the product relies on the guide wheel installed on the pinion ...
