Abstract

The utility model relates to a long stroke oil pumping machine with an inner engaged planetary gear to form a linear motion, which belongs to the technical field of oil production devices. The utility model is composed of a fixed electric machine 1, a speed reduction device 2, a stroke frequency scaling device 3, inner engaged planetary gear mechanisms 4, 5, 6, a gear rack 7, a gear 8, a stroke scaling device 9 and a chain wheel. Because the tooth number of the inner gear 6 is twice as the tooth number of the planetary gear 5, the gear rack 7 can move to and fro in a linear mode. The utility model has the advantages that the maximal acceleration of an oil pumping well rod is below 0.6 meter/second < 2 >, so the inertia impulse force is greatly decreased; the machine is sealed, and the performance of lubrication and wind sand resistance is good; the electric machine is fixed to enhance the using safety.

Description

Internal-gearing planet gear generates straight-line big stroke beam-pumping unit
This reality has the novel oil production equipment technical field that belongs to, and relates to a kind of improvement of big stroke beam-pumping unit.
At present, the kind of linear type pumping unit is more, and its superiority is that the oil pumping rate is higher, and power consumption is lower.But existing type kind all exists following deficiency, and one is because of reversing impact is big and frequent, so that fault is many, and the life-span is low; One is to do straight reciprocating motion because of the motor random device, so machine can't seal, causes insufficient lubrication, and the wind sand contamination is attacked seriously, and component wear is very fast.
The purpose of this utility model provides a kind of internal-gearing planet gear generation straight line motion pumping unit that reduces inertia impact and can realize machine.
The technical solution of the utility model is as follows:
Be fixed on the motor 1 on the support 17, for pumping unit provides power, motor 1 is to being connected with speed reducer 2 and number of strokes device for zooming 3 between the crank 4, the A of crank 4 is point articulated on frame, B point and planet wheel 5 are hinged, and the number of teeth of internal gear 6 is 2 times of the number of teeth of planet wheel 5, and the C of tooth bar 7 one ends and planet wheel is point articulated, and tooth bar 7 and gear 8 engagement driving, gear 8 is given steel wire drive wheel 10 by stroke device for zooming 9 with power transmission.
Casing 18 is except motor 1, steel wire drive wheel 10 and 12, and in the whole parts beyond the transmission steel wire 11 all are closed in.
The utility model advantage is: 1, the acceleration maximum value is lower than 0.6 meter per second 2, compare with conventional art and can hang down 5-7 doubly, compare also with best linear type pumping unit (ZL98236508X) and reduce about 40%, so inertial impact force descends significantly.2, realize the machine sealing, improved lubrication state and not the wind-engaging sand contamination attack, greatly reduce wearing and tearing.3, motor is fixed on the support, has eliminated the shortcoming that the linear type motor of oil extractor drags the line operation, has improved safety in utilization.
Fig. 1 is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
Wherein: 1, motor; 2, speed reducer; 3, strokes per minute number of times device for zooming; 4, crank; 5, planet wheel; 6, internal gear; 7, tooth bar; 8, gear; 9, stroke device for zooming; 10, steel wire drive wheel; 11, transmission steel wire; 12, steel wire drive wheel; 13, support; 14,15,16, telescoping shoring column; 17, support; 18, casing.
When planet wheel 5 rotated under crank 4 drives, it did planetary motion along being fixed on internal gear motionless on the frame 6.When the number of teeth of internal gear 6 was 2 times of the number of teeth of planet wheel 5, the C locus of point on the planet wheel 5 was the straight line of tooth bar 7 representatives.When crank 4 circled, the one way stroke of tooth bar 7 equaled the calibration garden diameter of internal gear.
Reduce cost in order to alleviate pumping unit weight and compact structure, less 6 designs of clam gear, so the stroke of tooth bar 7 is distal to the required oil pumping stroke of well bar.So for satisfying oil pumping stroke needs, through constituting stroke amplification device to steel wire drive wheel 10 with tooth bar 7 meshed gears 8, stroke device for zooming 9 between them, can cause the revolution difference of gear 8 and steel wire drive wheel 10, thereby realize the convergent-divergent of pumping unit stroke, to adapt to the oil recovery different needs, steel wire drive wheel 10 is identical with 12 sizes, transmission steel wire 11 1 ends are fixed on the wheel 10, and the other end of wheel 12 is that free end links to each other with the well bar.
