Abstract
The invention discloses a pumping unit reduction box sealing device, which comprises a transmission shaft, a bearing and a bearing cap. The transmission shaft penetrates through the bearing and the bearing cap. A sealing ring is arranged between the bearing cover and the transmission shaft. An oil baffle disc is additionally arranged between the bearing cover and the sealing ring. The bearing cap is installed in a cover plate. The bearing and the cover plate are matched with each other to fix the oil baffle disc. A felt is arranged at the matching position of the cover plate and the bearing cap. The pumping unit reduction box sealing device has the advantages that since the oil baffle disc is additionally arranged between the bearing cover and the sealing ring, the oil inlet amount of the cover plate is reduced, the oil pressure is decreased, the sealing between the bearing and the cover plate and the sealing between the bearing and the bearing cover are realized through the sealing ring and the felt, the sealing links are increased, the sealing effect is improved and the sealing effect of a reduction box is guaranteed.
Description
Technical field
The present invention relates to a kind of oil pumping unit reduction gearbox seal arrangement, belong to the speed reducer technical field.
Background technique
Oil leakage phenomenon often occurs in the oil extractor reduction gearbox shaft end, cause bearing and gear to can not get due cooling and lubricating, reduced the working life of equipment, and production crew need to clean greasy dirt through often shut-down well, supplement machine oil, both image crude oil production efficiency, increased again the manpower work, therefore, need to have been improved speed reducer.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: the oil pumping unit reduction gearbox seal arrangement that has proposed a kind of good sealing effect.
Technical solution of the present invention is achieved in that a kind of oil pumping unit reduction gearbox seal arrangement, comprise transmission shaft, bearing, bearing cap, transmission shaft, through bearing and bearing cap, is provided with seal ring between bearing cap and transmission shaft, also is provided with oil baffle disc between described bearing cap and seal ring; Described bearing cap is arranged in cover plate, and bearing coordinates oil baffle disc is fixed with cover plate; Described cover plate and bearing cap cooperation place are provided with felt.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of oil pumping unit reduction gearbox seal arrangement of the present invention, by oil baffle disc also is set between bearing cap and seal ring, reduce the oil inlet quantity of cover plate, reduce oil pressure, realize sealing by seal ring, felt between bearing and cover plate, bearing cap, increase the link of sealing, improve the effect of sealing, guaranteed the sealing effect of speed reducer.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation that accompanying drawing 1 is a kind of oil pumping unit reduction gearbox seal arrangement of the present invention;
Wherein: 1, transmission shaft; 2, bearing; 3, bearing cap; 4, seal ring; 5, oil baffle; 6, cover plate; 7, felt.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is a kind of oil pumping unit reduction gearbox seal arrangement of the present invention, comprise transmission shaft 1, bearing 2, bearing cap 3, transmission shaft 1, through bearing 2 and bearing cap 3, is provided with seal ring 4 between bearing cap 3 and transmission shaft 1, between described bearing cap 3 and seal ring 4, also is provided with oil baffle disc 5; Described bearing cap 3 is arranged in cover plate 6, and bearing 2 coordinates oil baffle disc 5 fixing with cover plate 6; Described cover plate 6 is provided with felt 7 with bearing cap 3 cooperation places; By between bearing cap 3 and seal ring 4, oil baffle disc 5 also being set, reduce the oil inlet quantity of cover plate 6, reduce oil pressure, realize sealing by seal ring 4, felt 7 between bearing 2 and cover plate 6, bearing cap 3, increase the link of sealing, improve the effect of sealing, guaranteed the sealing effect of speed reducer.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
