Abstract
The utility model provides a sealing device for a reduction gearbox of an oil pumping unit. The sealing device for the reduction gearbox of the oil pumping unit comprises a reduction gearbox body, a shaft, a bearing, an oil seal mechanism and a packing seal mechanism, wherein the oil seal mechanism comprises an oil seal sleeved outside the shaft, an oil seal steel sleeve and an oil seal frame; the oil seal is arranged on the oil seal frame; the oil seal frame is fixed on the reduction gearbox through screws; an oil throwing ring is also arranged on one side of the oil seal steel sleeve near the bearing and is fixed on the shaft; the packing seal mechanism comprises a sealing base sleeved outside the shaft; one end of the sealing base is fixed on the reduction gearbox body while the other end of the sealing base is connected to a sealing material base; the sealing base, the sealing material base and the shaft compose a sealed cavity; packing and a spring are arranged in the sealed cavity; one end of the spring is fixedly connected to the inner side face of the sealing material base. As double-seal is adopted in the scheme, the sealing device for the reduction gearbox of the oil pumping unit is good in sealing effect and can solve the problem of oil leakage of the reduction gearbox of the oil pumping unit efficiently.
Description
Technical field
The utility model relates to the technical field of pumping unit, especially a kind of oil pumping unit reduction gearbox seal arrangement.
Background technique
Pumping unit is the special device of oil extraction in oil field, and the speed reducer in pumping unit is again the key position in pumping unit, and in oil extraction in oil field work, oil leak of pumping unit speed reduction box problem is perplexing field produces enterprise always, not only waste, and also impact is produced.In prior art, to oil pumping unit reduction gearbox, conventionally adopt seal ring and soft packing to seal, while adopting seal ring sealing, after equipment operation overlong time, seal ring can be worn very soon and be aging, and starts leakage of oil in breakage, loses original sealing effect; While adopting soft packing to seal, because of long-term compressed distortion of soft packing, its elasticity can slowly diminish, and do not have the effect of auto-compensation, thereby sealing effect is poor.Based on the problems referred to above, the seal arrangement of pumping unit need to check frequently, changes in time, has increased like this manpower and materials and cost of production.The existing deficiency of prior art that Here it is.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, and provide a kind of technological scheme of oil pumping unit reduction gearbox seal arrangement, this scheme comprises oil seal mechanism and packing seal mechanism, adopt double seal, good sealing effect, can effectively solve the problem of oil leak of pumping unit speed reduction box.
This programme is achieved by the following technical measures: a kind of oil pumping unit reduction gearbox seal arrangement, comprise Gearbox, axle and bearing, the feature of this programme is: also comprise oil seal mechanism and packing seal mechanism, described oil seal mechanism comprises oil sealing, oil sealing steel bushing and the oil seal frame that is enclosed within axle outside, this oil sealing is arranged on oil seal frame, described oil seal frame is fixed on deceleration box through screw, at oil sealing steel bushing, near a side of bearing, is also provided with disc, and this disc is fixed on axle; Described packing seal mechanism comprises the sealing seat that is enclosed within axle outside, one end of sealing seat is fixed on Gearbox, the other end of sealing seat is connected with envelope material seat, described sealing seat, envelope material seat and axle three form closed cavity, in this closed cavity, be provided with filler and spring, one end of this spring is fixedly connected with the inner side surface of envelope material seat.
The feature of this programme also has, and described sealing seat is fixed on box body of speed reducer through clamping bolt.Between described sealing seat and envelope material seat, by adjusting bolt, connect.Described filler adopts felt or butter packing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1 is bearing, and 2 is Gearbox, and 3 is oil seal frame, and 4 is disc, and 5 is oil sealing, and 6 is oil sealing steel bushing, and 7 is clamping bolt, and 8 is sealing seat, and 9 is filler, and 10 is spring, and 11 is adjusting bolt, and 12 is envelope material seat, and 13 is axle.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, a kind of oil pumping unit reduction gearbox seal arrangement of this programme, comprise Gearbox 2, axle 13 and bearing 1, also comprise oil seal mechanism and packing seal mechanism structure, described oil seal mechanism comprises oil sealing 5 and oil sealing steel bushing 6 and the oil seal frame 3 that is enclosed within axle 13 outsides, and this oil sealing 5 is arranged on oil seal frame 3, and described oil seal frame 3 is fixed on Gearbox 2 through screw, at oil sealing steel bushing 6, near a side of bearing 1, be also provided with disc 4, this disc 4 is fixedly connected with axle 13.Described packing seal mechanism comprises the sealing seat 8 that is enclosed within axle 13 outsides, one end of sealing seat 8 is fixed on Gearbox 2 by clamping bolt 7, the other end of sealing seat 8 is connected with envelope material seat 12 by adjusting bolt 11, described sealing seat 8, envelope material seat 12 and axle 13 threes form closed cavity, in this closed cavity, be provided with filler 9 and spring 10, one end of this spring 10 is fixedly connected with the inner side surface of envelope material seat 12, and what described filler 9 adopted is felt or butter packing.
While using the utility model to seal, first oil seal mechanism is installed, then packing seal mechanism is installed.When oil seal mechanism is installed, first disc 4 is fixed on axle 13, again oil sealing support is fixed on reducer shell, oil sealing 5 and oil sealing steel bushing 6 are installed, make oil sealing steel bushing 6 and oil sealing support hold out against disc 4, can drive disc 4 to rotate when axle 13 rotates, disc 4 can be by the oil that overflows cavity to whipping in chamber, reduce oily spill-out and the pressure of oil to oil sealing 5, thereby reached good sealing effect; When packing seal mechanism is installed, first sealing seat 8 is arranged on Gearbox 2, between sealing seat 8 and axle 13, filler 9 is installed, again envelope material seat 12 is fixedly connected with sealing seat 8, make spring 10 withstand filler 9, when filler 9 use increase the axial force of 10 pairs of fillers 9 of spring by adjusting adjusting bolt 11 after a period of time, make filler 9 there is the function of auto-compensation, strengthened sealing effect.
Although above-mentioned, by reference to the accompanying drawings the embodiment of model utility is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
