Abstract
The utility model relates to a leakage prevention technology for a speed reduction box of an oil-field oil suction machine, in particular to an output shaft oil-leakage-prevention device for a speed reduction box of an oil sucking machine, which comprises a press cover, a sealing ring and a fastening screw bolt, wherein the press cover is fixed on a box body of the speed reduction box through the fastening screw bolt and the sealing ring. The output shaft oil-leakage-prevention device is characterized in that a lug boss circular ring I is also arranged on the output shaft arranged at the outer side of a bearing, and the maximum diameter of the lug boss circular ring I is smaller than the diameter of the outer ring of the bearing. Excessive machine oil for lubricating the bearing can flow back into the speed reduction box, the outward seeped machine oil is thrown back into the speed reduction box, the occurrence of the oil leakage phenomenon of the output shaft of the speed reduction box is avoided, the lubrication of a gear of the speed reduction box is ensured, the service life of the speed reduction box is prolonged, and the output shaft oil-leakage-prevention device has the advantages that the installation and the operation are simple, the use is convenient, the sealing effect is good, and the work efficiency is improved.
Description
Technical field
The utility model relates to oil-field oil pumper speed reducer leak proof technology, particularly a kind of oil pumping unit reduction gearbox output shaft oil leakage preventing apparatus.
Background technique
Pumping unit is a kind of visual plant in the field produces, for many years continuously the running back since component wear or maintain not in placely cause reduction gearbox output shaft the lubricating oil leakage influence to occur and produce.The oil pumping unit reduction gearbox output shaft sealing means at present field produces scene, mainly be that the high pressure felt seal ring that itself carries when relying on oil pumping unit reduction gearbox to dispatch from the factory seals, but this encapsulating method effect is relatively poor, the leakage of oil of output shaft position is serious, not only causes loss of lubrication, and influences the pumping unit management development, after the loss of lubrication, gear can not get good lubrication, influences the working life of speed reducer, even causes speed reducer to scrap.Prior art can not address the above problem.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of technological scheme of oil pumping unit reduction gearbox output shaft oil leakage preventing apparatus is provided at the above-mentioned defective of prior art existence, adopt the oil pumping unit reduction gearbox output shaft of the technical program can effectively prevent lubricating oil leakage, reach the prolongation pumping unit purpose in working life.
The utility model is to realize like this, a kind of oil pumping unit reduction gearbox output shaft oil leakage preventing apparatus, it comprises gland, seal ring, clamping bolt, gland is fixed on the speed reducer casing by clamping bolt and seal ring, it is characterized in that, on the output shaft in the bearing outside boss annulus I is installed also, the maximum diameter of boss annulus I is less than the diameter of bearing outer ring.
On the output shaft in the described boss annulus I outside boss annulus II is installed also, the maximum diameter of boss annulus II is less than the diameter of bearing outer ring, and is provided with the intilted groove more than 2.
The beneficial effects of the utility model are: this device can be back to the unnecessary machine oil of lubricating bearings in the speed reducer, get back in the speed reducer getting rid of toward machine oil to seepage, stopped the generation of reduction gearbox output shaft oil leakage phenomenon, guaranteed the lubricated of speed reduction gear box, prolonged the working life of speed reducer, and have that fitting operation is simple, easy to use, good sealing effect, increase work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of boss annulus II among Fig. 1.
In the accompanying drawing, 1-speed reducer casing, 2-axle sleeve, 3-clamping bolt, 4-output shaft, 5-boss annulus I, 6-groove, 7-seal ring, 8-boss annulus II, 9-gland.
Embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model and principle are described further.
As shown in the figure, a kind of oil pumping unit reduction gearbox output shaft oil leakage preventing apparatus of the present utility model, it comprises gland 9, seal ring 7, clamping bolt 3, gland 9 is fixed on the speed reducer casing 1 by clamping bolt 3 and seal ring 7, it is characterized in that, boss annulus I 5 also is installed on the output shaft 4 in bearing 2 outsides, and the maximum diameter of boss annulus I 5 is less than the diameter of bearing 2 outer rings; On the output shaft 4 in described boss annulus I 5 outsides boss annulus II 8 is installed also, the maximum diameter of boss annulus II 8 is less than the diameter of bearing 2 outer rings, and is provided with the intilted groove 6 more than 2.
Use the speed reducer of this model utility, in running, the unnecessary machine oil of lubricating bearings 2 can be back in the speed reducer by the gap between bearing 2 Internal and external cycles, the maximum diameter of boss annulus I 5 is less than the diameter of bearing 2 outer rings, the machine oil height that can guarantee output shaft 4 like this soaks less than boss annulus I, prevents that in output shaft 4 operation process boss annulus I from getting rid of oil; Simultaneously, the maximum diameter of boss annulus II 8 guarantees that less than the diameter of bearing 2 outer rings machine oil is back in the speed reducer smoothly, and the intilted groove 6 that has can make the machine oil that flows down on the output shaft get rid of by action of centrifugal force and get back in bearing 2 and the speed reducer.Evidence adopts speed reducer of the present utility model to stop the generation of reduction gearbox output shaft oil leakage phenomenon, has guaranteed the lubricated of speed reduction gear box, has prolonged the working life of speed reducer.
Claims (2)
1. oil pumping unit reduction gearbox output shaft oil leakage preventing apparatus, it comprises gland, seal ring, clamping bolt, gland is fixed on the speed reducer casing by clamping bolt and seal ring, it is characterized in that, on the output shaft in the bearing outside boss annulus I is installed also, the maximum diameter of boss annulus I is less than the diameter of bearing outer ring.
2. a kind of oil pumping unit reduction gearbox output shaft oil leakage preventing apparatus according to claim 1, it is characterized in that, on the output shaft in the described boss annulus I outside boss annulus II is installed also, the maximum diameter of boss annulus II is less than the diameter of bearing outer ring, and is provided with the intilted groove more than 2.
