Abstract

The utility model relates to a ring-gear and long-stoke type oil-pumping unit, which belongs to the technical field of oil exploiting equipment. The utility model has the structure that a dragging transmission system is composed of a speed changer and an annular speed reducer, and the output shaft of the speed reducer is engaged with an opening type annular gear ring fixed in a crown sheave. The annular gear ring carries out cyclic positive and negative rotation of non-switching type under the condition of the rotation of a gear of the output shaft, and non-circular gear part at the two opening positions of the opening type annular gear ring is a conversion fraction of the crown sheave which carries out the cyclic positive and negative rotation. The utility model has the advantages that the structure is simple, the mechanical efficiency is more than 50 per cent, the transmission mechanism is a gear transmission, the operation is stable and reliable, the service life is long, and the utility model can be used for meeting the requirement of a large torque machine, the stroke of the utility model can be determined by a machine frame, the degree of balance of the utility model reaches to more than 98 per cent after be regulated by a balancing box, and thus, the utility model can realize long stroke and large displacement. Compared with the swinging beam machine of the same type, the energy can be saved by more than 30 per cent.

Description

Ring tooth long stroke pumping unit

Technical field:

The utility model belongs to the oil exploration equipment technical field, relates to a kind of improvement of oil pumper.

Background technology:

At present, in the oil exploitation at home and abroad, use beam pumping unit widely, be characterized in simple in structure, arranged higher application life, but because of its design feature, determined to exist the shortcoming that is difficult to overcome, as be difficult to realize the production demand of the big discharge capacity of long stroke, its counterweight is difficult to adjust to such an extent that mate with suspending point loading, make motor-driven year of walking beam excessive, work operational system disequilibrium wastes energy; In order to improve output, strengthen jig frequency quantity, impel critical pieces such as oil pumper and pump extension system to produce fatigue failure and inefficacy prematurely, the possessor transforms the walking beam machine to the greatest extent, above-mentioned shortcoming still is difficult to overcome, DeGrain, so people think that at large the walking beam machine is the oil pumper that efficient is low, energy consumption is high.

Summary of the invention:

Technical problem to be solved in the utility model is:

A kind of ring tooth long stroke pumping unit that switching can realize rotating that do not have is provided.

The technical solution of the utility model is:

The output of motor directly and coupling device link, drag transmission system by speed changer and annular reductor composition, speed reducer output shaft is meshed with open type annular gear ring in being fixed on crown sheave, under the output shaft gear rotation drives, annular gear ring does not have the periodicity rotating of suitching type, and the non-knuckle-tooth of open type annular gear ring two opening parts partly carries out the periodically conversion portion of rotating for crown sheave.

Reduction gearing and axles all in the ring-like reductor all are assembled on the planet carrier, form an integral body, and planet carrier revolves round the sun under the support of steel ball, ring-like gear ring and output shaft gear center to center distance when adjusting commutation.

The beneficial effects of the utility model are:

It is simple in structure, and mechanical efficiency is more than 50%; Transmission mechanism is gear drive; The reliable long service life of stable working, can realize the needs of high pulling torque type; Frame determines its stroke, and through the adjusting of tandem-driving bogie, the degree of balance can reach more than 98%; But thereby can realize long stroke, big discharge capacity, compare energy conservation more than 30% with same type machine walking beam machine.

Wherein: the 1st, frame, the 2nd, polished rod, the 3rd, polished rod eye, the 4th, belt of wire rope, the 5th, crown sheave assembly, the 6th, tandem-driving bogie, the 7th, motor, the 8th, fluid-flywheel clutch, the 9th, speed changer, the 10th, ring-like reductor, the 11st, planet carrier, the 12nd, steel ball, the 13rd, crown sheave, the 14th, overhead traveling crane wheel shaft, the 15th, baffle plate, the 16th, open type annular gear ring, the 17th, output shaft gear.

The specific embodiment:

Of the present utility model all drag, the parts in the transmission, operating mechanism, all be installed on the crown sheave bearing, form an integrated member, and be assemblied in the top of frame; The crown sheave assembly comprises that the coupling device and the speed changer that are equipped with on the motor output shaft link, and is assembled on the ring-like reductor; Be meshed with annular gear ring in being fixed on crown sheave through the speed reducer output shaft gear again.Wire belt is arranged at crown sheave top, and an end links by polished rod eye and polished rod, and the other end walks around crown sheave and tandem-driving bogie joins, and tandem-driving bogie is in the truss inside of frame; Crown sheave back and forth rotates under the drive of annular gear ring, makes belt of wire rope drive polished rod by rope rotator and finishes oil pumping work.

Ring-like reductor is a kind of reductor of special structure form, and output shaft gear and other driving gearshaft and gear all are installed on the planet carrier.The planet carrier of ring-like reductor relies on steel ball to be supported on the reducer shell, and ring-like gear and output shaft gear are according to the compensation of revolving round the sun of the needs of meshed center distance during commutation.
