Its Structure Mechanism of the utility model oil production machine is taken from the hypocycloid equation, sees Fig. 1, and its definition is: a circumference (a) rolls along the inside of another circumference (A) and when fricton-tight, (0) line of being retouched a bit on the circumference (a). As D(A)/D(a)=2 the time, the line that the upper point (0) of circumference (a) is retouched is a diameter of circumference (A). According to this principle, surely round internal gear (1) of the present utility model is fixed on the support (16); Moving circle external gear (2) meshes and is placed on crank (4) bearing of bent axle (3) with (1); Bent axle (3) is a T shape steel-casting, and it is the axle center of this machine revolving part, and crank (4) is loaded on an end of T oblique crank Z (3) securely with securing member, consists of bent axle, and bent axle (3) places the bearing block of bearing (5), and bearing (5) is fixed on the support (16). The rotating shaft of motor (6) and bent axle (3), crank (4) are installed on the transverse arm of bent axle (3) abreast, driving wheel (2), motor (6) consist of symmetrical slewing equipment at transverse arm, and motor torsion is delivered on the internal tooth of fixed wheel (1) by gear (7), (8), (9), (2). Take in the axle center of T shape bent axle (3) as the transverse arm two ends of pivot, the matter of its driving wheel (2) Amount adds that putting forward the quality that loading with of pump bar be equal to other end motor (6), gear (7), (8), (9) adds the motor torque, and this device is got and replaced common balancing weight. When motor (6) obtains electric power from collector ring (15), when motor rotary shaft cogs (6) generation torsion, (4) on the bent axle (3), (6), (7), (8), (9), (2) rotatablely moving take (3) as the axle center appears in total movement spare, and driving wheel (2) is subjected to the restriction of gear (1), the not only revolution take axle (3) as axle, the simultaneously also rotation take crank (4) as axle, the rotation-revolution period ratio is D(1)/D(2)=2, also namely surely justify internal gear (1) and move centripetal arc dia D(1 in its tooth of circle external gear (2))/D(2)=2, and moving circle external gear (2) is when fixed round internal gear (1) inner periphery rolls by the engagement of tooth, move on circle external gear (2) circumferential edge a bit---turn the diameter that axle (10) is retouched into fixed circle (1), when moving circle external gear (2) turns to 720 °, turn the reciprocal of the complete in line motion of axle (10), this reciprocating motion affects pump bar (11) work done, turning axle (10) affects pump bar (11) back and forth to move up and down in pump (12), change the volume of penstock, form one positive one negative pressure reduction, thereby crude oil is mentioned on the ground. (13) be to hide the grid outer casing, two partly before and after it was divided into, and with whole parts sealing, anti-invasion and attack of unloading wind sand sleet ensure normally carrying out of oil production machine. (14) be the suspension ring supports, (15) are the motor power collector rings.

Transverse arm on the T shape bent axle (3) of the utility model, it rotates take bearing (5) as the center of circle and moves back and forth in turning the upper accomplish linear of axle (10); Bearing (5) also is transverse arm---the fulcrum of lever, namely take advantage of the arm of force to equal with motor (6) as the force take the torque of wheel (2) and wheel (1) engaging tooth, the attach most importance to correspondence of dot product weighing arm of the synthetic gross weight of ratio wheel (7), (8), formation work (carrying oil) heavy burden add potential energy subtract the light lotus of return (air-breathing) add kinetic energy (accumulation of energy) be comparable to zero complementary balanced. For this reason, heavy, the power lotus amount in the two ends of fulcrum (5) will be according to working medium operating mode (viscosity, weight, frictional dissipation etc.) rule and motor power (output) and given, mainly meet following principle: when turning axle (10) when affecting pump bar (11) upwards to put forward oily merit (arm of force moves upward), motor is puted forth effort, and this moment, motor was exerted oneself and lucky being fully loaded with from the potential energy compensated motor of weighing arm end (6), (7), the release of (8) acquisition weight; Affect pump bar (11) to do to reply that (arm of force is downward downwards when turning axle (10), operation) motor underloading, at this moment upwards operation of weighing arm end (6), (7), (8), motor makes potential energy for the upwards elevate a turnable ladder that improves weighing arm or accumulation of energy is puted forth effort, motor is fully loaded, and consequently: bent axle (3) is connecting lever (10) in front 180 ° of corners In the individual reciprocal stroke, the oily workload loss of weight arm release potential energy merit of carrying of pump bar (11) equals the motor full-load power; In (10) strokes that return of connecting lever, the return of pump bar (11) load weighting arm absorbs kinetic energy (accumulation of energy) merit and equals the motor full-load power in rear 180 ° of corners. Cycle changes and so forth, still guarantees the motor full load operation of all loading. Cancelled common balancing weight, actual is that parts have two functions simultaneously, has saved material, has also saved electric power.
