Description

The gear wheel reversing long stroke pumping unit

Relate to the field: the present invention relates to a kind of oil pumper, especially a kind of gear wheel reversing long stroke pumping unit.

Prior art: at present, advantage such as the oil pumper that uses in oil exploitation mainly is a beam pumping unit, and this type of oil pumper primary structure is simple, working stability is reliable, but that deficiency is a stroke is short, energy consumption is big; Each oil field is all at long, the energy-conservation blue elephant of development stroke in recent years, on December 31st, 2003, the patent No. of bulletin was that 032114362 Chinese utility model patent manual discloses a kind of: ring tooth long stroke pumping unit, its principal character is: being cogged by speed reducer output shaft is meshed with an open type annular gear ring, and driving open type annular gear ring does not have the rotating of suitching type cycle, the annular reductor is assembled on the planet carrier, planet carrier revolves round the sun under steel ball supports, annular gear ring and output shaft gear center to center distance when adjusting commutation; It is moving axis that the speed reducer output shaft gear of this kind structure meshes two gear shafts relative with the open type annular gear ring, the relative position of diaxon is constantly to change in the engagement rotation process, and output shaft gear is to lean on the tooth top and the contacting of tooth root of two gears to locate with nearly centre distance in the annular gear ring engagement process.This contact engagement belongs to " undercut ", can produce two gears and " kill " phenomenon, perhaps can rotate, but therefore tooth top and tooth root does not meet the gear transmission technology requirement with heavy wear yet; Speed reducer output shaft gear drive annular gear ring rotates, when turning to the tooth conversion of the non-garden of opening part, though reductor revolution under steel ball supports can be adjusted the relative position of engagement of output shaft gear and annular gear ring, but speed reducer output shaft is not because of around the non-knuckle-tooth rotational positioning of annular gear ring opening part controlling organization, only engagement drives by two gear teeth faces, output shaft gear also not inevitablely by (outward) part in (interior) part is transformed into outside the annular gear ring, therefore can not guarantee to reach conversion and commutate.

Summary of the invention: the purpose of this utility model is: in order to overcome the shortcoming that above-mentioned technology exists.Provide a kind of gear drive not have the commutation of switching, working stability is reliable, energy-conservation long stroke pumping unit; The technical solution of the utility model is: the gear wheel reversing long stroke pumping unit is by frame, motor, gear drive, crank driving device, compositions such as gear track rotor plate, head sheave car, wire rope, balance weight; Wherein: motor drives crank driving device by belt pulley and gear reduction transmission system and rotates, the gears engaged of the roller of crank axle output and driven wheel and gear track ring, the forward and reverse rotation of driven wheel orbit ring drives the continuous both forward and reverse directions of crown sheave and rotates; In the casing that frame top is installed, a rotating disk is arranged, fix an external gear by belt track, internal gear and two semicircles in the rotating disk side and be connected the circular gear track ring jaggy of gear train all-in-one-piece, the track of gear track ring one side is justified parallel with gear compound graduation and is an integral body; Be fixed on power transmission shaft one axle head on the casing and stretch on the gear track ring in the middle of the inside and outside track, when the gear track ring turns to the junction, play position-limiting action; With bearing fixing crank is installed on the power transmission shaft, one crank axle is installed on the crank, driving gear engagement on travelling gear, travelling gear and the power transmission shaft is installed in the middle of the crank on the crank axle, the crank axle output is equipped with a roller and a driven wheel, the engagement that cogs of driven wheel and gear track ring, the tangent rolling of getting on the right track of roller and gear track ring, in order to the center to center distance that control driven wheel and gear track ring cog, the assurance correct engagement; When motor drives travelling gear and crankshaft rotation by the deceleration transmission system, when the engagement of roller and driving gear drives gear track ring turns to outer (interior) gear and is connected the gear junction, transmission shaft end spacing down, roller and driven wheel together with crank together around power transmission shaft along be connected gear by outside (interior) gears engaged rotate carry out the transition in (outside) driven wheel orbit ring backward rotation also on the gear, main shaft drives the continuous forward and reverse rotation of crown sheave by shaft coupling on the rotating disk, constantly mentions or puts down sucker rod and finish oil pumping around hanging over wire rope on the crown sheave; The utility model does not switch commutation because gear drive has, the complete machine stable and reliable operation, and the polished rod speed of service is even, and stroke is long, and discharge capacity is big, compares with beam pumping unit and more saves the energy.
