Description

Planet ring gear oil pumper

Technical field

The present invention relates to petroleum recovering machinery equipment field, specifically is a kind of planet ring gear oil pumper, (hereinafter to be referred as the ring gear oil pumper).

Background technology

At present, recover the oil and be traditional beam pumping unit in the oil field, though through various improvement and long-lived characteristics, its motion principle is constant, still has the high deficiency of energy consumption.The patent No. is: 200920019023.1 long annular rack oil pumping machine and number of patent application are: the microscler rack oil pumping machine of 200910020560.2 tilting; What adopt is to do reciprocating linear motion through annular rack of a pinion one way engagement; Drive rope, promote sucker rod through pulley and move up and down.This product is not ostracised when making the pinion tooth bar and is remained engagement, and that leans on is mounted in directive wheel on the pinion in the annular groove of the balance weight of stationary rack, ensures the movement locus of pinion in cannelure.During switching-over, when annular semicircle tooth was engaged to the another side flank of tooth, what lean on was the horizontal move left and right of break-in frame to pinion from one side flank of tooth of tooth bar.This structure exists: directive wheel contact surface in groove is little, and load is big, and quick abrasion causes pinion swing gap big, loses the accuracy of mesh, and other damage of components are accelerated.In addition, the break-in frame is when moving horizontally, and the center to center distance of motor belt also can change thereupon, and the belt degree of tightness is differed.Also exist simultaneously manufacturing process complicated.

Summary of the invention

The objective of the invention is to overcome the deficiency in the above-mentioned technology, provide that a kind of manufacturing process is simple, good energy-conserving effect, reliable stable, the planet ring gear oil pumper of long service life.

The present invention is for realizing above-mentioned purpose; Realize through following technical scheme: planet ring gear oil pumper is made up of frame, motor, bearing, gear-box, solar wheeling tooth axle, deceleration tooth axle, planet tooth axle, reduction gearing, annular rack, outstanding rope system and check mechanism; It is characterized in that: central rack is equipped with a bearing; One gear-box is installed on this bearing, a solar wheeling tooth axle, deceleration tooth axle and planet tooth axle are installed on this gear-box, on this deceleration tooth axle and the planet arbor wheel reduction gearing is installed all; Wherein, Reduction gearing on the solar shaft tooth axle engagement deceleration tooth axle, the reduction gearing on the reduction gearing engagement planet tooth axle, planet tooth axle then meshes annular rack.Because these tooth bar two ends are the long annular of semicircle, therefore, when solar wheeling tooth engagement reduction gearing and the rotation of deceleration tooth axle, through slowing down, planet tooth axle then meshes the annular rack moving linearly.In the time of in moving to annular flank of tooth entering guide ring, under the effect of guide ring, tooth bar continues to keep straight on; Planetary gear then meshes semi-circle gear and moves to the right from the left side of tooth bar; At this moment, annular rack begins inverted running, realizes pumping of tooth bar; Drive the outstanding rope system of frame top, reach the purpose of oil pumping.Because planet tooth axle is installed on the gear-box, therefore, gear-box is that the center swings with the solar wheeling tooth axle also on support thereupon, at the right and left locating piece is installed all, is used for the swing location of gear-box, to guarantee the accuracy of mesh and the bearing capacity of rack-and-pinion.The present invention has simple in structure, and is reliable, and efficient is high, and switching-over is steady, characteristics such as economy and durability.

The specific embodiment

See that from accompanying drawing planet ring gear oil pumper is made up of base, frame, motor, bearing, gear-box, central gear shaft, reduction gearing, planet tooth axle, fast gear, annular rack, outstanding rope system and check mechanism.It is characterized in that: frame 2 middle parts are equipped with a bearing 6; One gear-box 7 is installed on this bearing 6, a solar wheeling tooth axle 9, deceleration tooth axle 15 planet tooth axles 10 are installed on this gear-box, a reduction gearing 20,21. all is installed wherein on this deceleration tooth axle 15 and the planet tooth axle 10; Reduction gearing 20 on the solar wheeling tooth axle 9 engagement deceleration tooth axles 15; Reduction gearing 21 on the deceleration tooth axle 15 engagement

planet tooth axles

10,10 engagements of planet tooth axle annular rack 4. is equipped with a switching-over guide wheel 11 at an end of planet tooth axle 10, because annular rack 4 two ends are the long annular of semicircle; Therefore; When solar wheeling tooth axle 9 engagement reduction gearing 19 and reduction gearing 15 rotations, through slowing down 10 engagements of planet tooth axle annular rack, 4 moving linearlies.When getting in the guide ring 14 when moving to annular tooth, under the effect of guide ring 14, tooth bar continues to keep straight on; 10 engagements of planet tooth axle semicircle tooth moves to the right from the left side of tooth bar, at this moment, and annular rack 4 beginning inverted runnings; Realize pumping of tooth bar; The pulley 13 that drives frame 2 tops through rope 12 hangs the rope systems, promotes sucker rod 19, reaches the purpose of oil pumping.Above-mentioned annular rack 4 is installed on the slide block toothholder 5, and directive wheel 16 then is installed on the slide block toothholder 5, and frame 2 is installed on the base 1, and guide rail 17 is installed on the

frame

2, and 16 of directive wheels roll on guide rail 17, thereby the straight line of realizing slide block toothholder 5 moves up and down.Because planet tooth axle 9 is installed on the gear-box 7; Therefore, during switching-over, gear-box 7 is that the center swings with the solar wheeling tooth axle also on bearing 6 thereupon; At the right and left locating piece 18 is installed all; The swing that is used for gear-box 7 is located, and has guaranteed the accuracy of mesh and the bearing capacity of rack-and-pinion, sees Fig. 6, Fig. 7.

Its structure and transmission principle do; The belt 8 that drives on the solar wheeling tooth axle 9 when motor 3 rotates, but also hand is seen Fig. 2 with the deceleration of direct connection structure through reduction gearing; Planet tooth axle 10 engagement annular racks 4 moving linearlies, as can beappreciated from fig. 5, when being engaged to the semicircle tooth of annular rack 4; Directive wheel 11 on the planet tooth axle 10 also gets in the guide ring 14 that is installed on the slide block toothholder 5, and under the effect of guide ring 14, planet tooth axle 10 must mesh the semicircle tooth and move to the right from the left side; Realize switching-over, when moving to the semicircle tooth of the other end, equally in the above described manner; Planet tooth axle 10 moves to the left side from the right, reaches the purpose that slide block toothholder 5 pumps, and sees Fig. 6, Fig. 7.Slide block toothholder 5 pulling ropes 12 promote sucker rod 19 through pulley 13, to realize oil pumping, see Fig. 1.

The present invention has reduced corollary equipments such as reductor and shaft coupling because simple in structure, therefore, has reliable stablely, and supporting capacity is big, good energy-conserving effect, long service life, characteristics such as easy to maintenance.
