Abstract
The utility model provides an ultra-low-stroke-frequency pumping unit secondary speed reducing device which comprises a motor. The upper portion of a motor bracket is connected with a bottom plate of the motor, the lower portion of the motor bracket is connected with an installation bottom plate, a coaxial type speed reducer is also arranged on the installation bottom plate, the coaxial type speed reducer is connected with the motor, and a small belt wheel is arranged on an output shaft of the coaxial type speed reducer. The ultra-low-stroke-frequency pumping unit secondary speed reducing device is formed by modifying a conventional walking beam type pumping unit, the rotation speed of the motor is lowered before being transmitted to a cylindrical gear speed reducer so as to meet the requirement for low stroke frequency of the beam pumping unit, and the original structure of the pumping unit is not damaged. The motor bracket supports the bottom plate of the motor, coaxiality of a motor shaft and an input shaft of the speed reducer is guaranteed under the working condition of severe vibration of the pumping unit so that the secondary speed reducing device can be adaptive to bad field working conditions, and the secondary speed reducing device has the advantages of being simple in structure, reliable in work, low in cost, and capable of conveniently adjusting stroke frequency.
Description
Technical field
The utility model relates to a kind of driving speed reduction gearing of oil pumper of beam type, belongs to oil production equipment technical field.
Background technology
At present, oil pumper is the ground driving arrangement of sucker rod pumping.By its basic structure, oil pumper can be divided into beam type and without the large class of beam type two.At present domestic and international application is beam pumping unit the most widely, is to be slowed down through belt transmission and secondary cylindrical gear reducer by motor, drives walking beam to realize reciprocally swinging by crank and connecting rod and crossbeam.But owing to being subject to the restriction of transmission device gearratio, the beam pumping unit jig frequency of extensive use is at present higher, cannot meet low permeability oil field, the requirement of stripper well to low jig frequency oil pumping.Too high jig frequency causes the running for a long time under low submergence, the not enough condition of even serious feed flow of most stripper wells, and this not only causes, and pump efficiency is low, system effectiveness is low, a large amount of wastes of system energy consumption.And severe exacerbation the condition of work of oil well pump and sucker rod, seriously aggravate oil well pump wearing and tearing, disconnected de-, the rod and tube partial-wear of rod tube, lowered the pump overhaul period, increased the expense of oil well pump detection and workover.
In order to address the above problem, patent 02237777.8 discloses a kind of speed reducer for oil pumping unit, adopt the belt of former driving device of oil pumping unit slow down and cylindrical gear reducer between installed one-level belt reduction unit additional, realized the secondary speed-reducing of super low-frequency-stroke pumping machine.But it exists, complexity is installed, needs two cover belt stretchers, and need running check to regulate.And oil pumper operation in the wild, easily negligence of management, therefore this kind of secondary speed-reducing device operating mode applicability is poor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy for installation, adapt to the deceleration device of oil pumper field work and Maintenance free management, as again slowing down on the basis of original speed reducer for oil pumping unit, to realize the requirement of beam pumping unit low jig frequency.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of super low-frequency-stroke pumping machine secondary speed-reducing device, comprise motor, it is characterized in that: electric machine support top is connected with the base plate of motor, electric machine support bottom is connected with mounting base, and coaxial-type reductor is also located on mounting base; Coaxial-type reductor connects motor, and small pulley is located on the output shaft of coaxial-type reductor.
Preferably, the output shaft of described motor connects described coaxial-type reductor by shaft coupling, and described motor and coaxial-type reductor are all located on adpting flange.
The super low-frequency-stroke pumping machine secondary speed-reducing device that the utility model provides is for low permeability oil field, the requirement of stripper well to low jig frequency oil pumping, conventional beam-pumping unit is transformed, motor is lowered at the rotating speed being transferred to before cylindrical gear reducer, to realize the requirement of beam pumping unit low jig frequency.Motor adopts B35 mounting structure form, and the base plate of electric machine support support motor can, under the operating mode of oil pumper judder, guarantee the alignment of motor shaft and reductor power shaft, thereby guarantee that secondary speed-reducing device can adapt to the severe operating mode in field.
The device that the utility model provides has overcome the deficiencies in the prior art, replaces the drive motors of former beam pumping unit, realizes the requirement of low jig frequency oil pumping; Simple in structure, reliable operation, with low cost and adjusting stroke frequency convenient, do not destroy the original structure of oil pumper.
