Abstract
The utility model relates to a ground drive unloading main shaft device of single screw pump used for the mechanical oil distracting of oil field and well. Two ball bearings(11, 10), a conical sleeve(3) and a transmission sleeve(9) are arranged between a main shaft(1) and a belt wheel(4); the twp ball bearings act on a box(8) through the transmission sleeve(9); the other side of the belt wheel(4) is provided with a connecting sleeve(12) and a key(2) on the main shaft(1). As the belt wheel is not directly arranged on the main shaft, but two ball bearings are arranged on the box through the transmission sleeve so that the main shaft discharges the radial load(the pull on the belt wheel). As the radial transmission force is discharged, the deflection of the main shaft is reduced so as to be beneficial for the stability of the operation. At the same time, the service life of bearings on he main shaft so as to reduce the labor intensity and cost.
Description
(1) technical field:
The utility model belongs to the helical rotor pump ground surface driving unload-type main shaft device on the well mechanical oil recovery of oil field.
(2) background technique:
Oil pumping screw pump is a kind of novel oil recovery machiner, both has been applicable to that the general thin oil of exploitation contained well, is applicable to that also high viscosity heavy oil, the content of wax contain gummy oil, contain the oil well of sand oil and big oil-gas ratio.It is made up of down-hole helical rotor pump and surface drive two-part.The two is delivered to the down-hole to well head power by rotatablely moving of sucker rod, driven pump work by strengthening grade pumping rod as flexible connection.Surface drive adopts belt and gear the two poles of the earth to slow down, and with the method speed governing of replacing belt wheel.During work, the main shaft of drive unit given transmission of power by belt by motor, transmission by the gear on the main shaft, make sucker rod produce rotation, the rotor that sucker rod drives subsurface progressive cavity rotates in stator, during rotor rotation, the oil that sucks in the ingress enters oil transport pipeline along with the spiral motion of cavity is discharged from well head.Accompanying drawing one is seen in the main movement transmission of the helical rotor pump surface drive that uses on the oil field at present.As can be seen from the figure, there are following two shortcomings in this structure: the one, and belt wheel directly is contained on the main shaft, makes main shaft bear radial load (on the belt wheel with pulling force), and the amount of deflection of main shaft increases, and main shaft is flexible, thus the stationarity of influence running; The 2nd, because the amount of deflection of main shaft increases, main shaft is flexible, and the stationarity of influence running so the bearing on the main shaft very easily damages, is brought great inconvenience to maintenance, has improved labor intensity, has improved cost simultaneously.
(3) model utility content:
Technical problem to be solved in the utility model is at the problem that exists in the background technique, and a kind of helical rotor pump ground surface driving unload-type main shaft device that improves smoothness of operation is provided.
The invention for solving the technical problem can reach by following technical solution: two ball bearings, tapered sleeve, drive sleeve (9) are housed between main shaft and belt pulley; Two ball bearings act on the casing by drive sleeve; On main shaft, adorn joint sleeve, key at the belt pulley opposite side.
Installation on above this main shaft of forecast scheme configuration because belt wheel directly is not contained on the main shaft, but is installed on the casing by drive sleeve by two ball bearings, makes main shaft shed radial load (on the belt wheel with pulling force).
The utility model is compared with the above-mentioned background technology can have following beneficial effect: because belt wheel directly is not contained on the main shaft, but be installed on the casing by drive sleeve by two ball bearings, make main shaft shed radial load (on the belt wheel with pulling force).Owing to shed radially driving force, the amount of deflection of main shaft is reduced, thus the stationarity that helps turning round.Simultaneously, prolong the working life of main shaft upper bearing (metal), thereby reduced labor intensity and cost.
(4) description of drawings:
Accompanying drawing 1 is an installation diagram on the existing main shaft;
Accompanying drawing 2 is installations diagram on this main shaft.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
In conjunction with shown in Figure 2, two ball bearings 11,10, tapered sleeve 3, drive sleeve 9 are housed between main shaft 1 and belt pulley 4 by Fig. 1; Two ball bearings act on the casing 8 by drive sleeve 9; On main shaft 1, adorn joint sleeve 12, key 2 at belt pulley 4 opposite sides.
The installation that above scheme constitutes at main shaft 1, motive force (motor) passes to main shaft 1 by belt wheel 4, joint sleeve 11 keys 2, realizes reduction speed ratio through the transmission of a pair of umbrella wheel.On the belt wheel with pulling force do not act directly on the main shaft, but act on the casing 8 by drive sleeve 9 by two ball bearings 11.The ratchet 6 of anti-reverse mechanism, the driving force of ratchet 5 also act on the drive sleeve 9.These two kinds of power are the bearing 7 on the main shaft all, so the amount of deflection of main shaft has reduced, also improved with regard to corresponding the working life of bearing.
Claims (1)
1, a kind of helical rotor pump ground surface driving unload-type main shaft device that relates on the well mechanical oil recovery of oil field, contain main shaft (1) and go up belt pulley (4), tapered sleeve (3), ratchet (5), ratchet (6) and the casing of installing (8), it is characterized in that: two ball bearings (11,10), tapered sleeve (3), drive sleeve (9) are housed between main shaft (1) and belt pulley (4); Two ball bearings act on the casing (8) by drive sleeve (9); Go up dress joint sleeve (12), key (2) at belt pulley (4) opposite side in main shaft (1).
