Abstract
The utility model relates to 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 bearing cover and a gland, wherein a sealing ring is arranged in the seam allowance of the central hole of the bearing cover; the gland is fixed on the bearing cover through a first bolt; a circular ring bump is arranged on the lower part of the inner side of the gland and is vertical to the gland; a screw hole is formed in the circular ring bump; an anti-dust ring is arranged between the circular ring bump and a rotating shaft; a baffle is arranged between the anti-dust ring and the circular ring bump; a second bolt is mounted in the screw hole. The sealing device for the reduction gearbox of the oil pumping unit has the beneficial effects that: sealing is realized as an axial pressure from the circular ring bump to the sealing ring enables the sealing ring to be deformed elastically so as to accumulate certain energy and enables pressure contact to be formed between the shaft surface of the rotating shaft and the sealing ring, and the anti-dust ring is tightly attached to the rotating shaft as the second bolt is rotated to generate a radial pressure for the baffle; in addition, the sealing device for the reduction gearbox of the oil pumping unit is reliable in design principle and simple in structure, and achieves very wide application prospect.
Description
Technical field
The utility model belongs to field mining equipment technical field, relates to a kind of oil pumping unit reduction gearbox, especially a kind of seal arrangement of oil pumping unit reduction gearbox.
Background technique
Continuous progress and development along with economic society, oil is also more and more important as role in mankind's industrial processes, as industrial a kind of important energy source resource, oil has become and the closely bound up and requisite raw material of mankind's daily life, and oil affects a national economic lifeline equally.Therefore, the production efficiency of oil and yield have very important impact to national economic lifeline and the daily life of people equally, if the too low reduction that will cause oil extraction of the production efficiency of oil, thereby have a strong impact on a national industrial production and quality of residents'life.So improving petroleum production efficiency and yield is the important topic of petroleum industry always.
The exploitation instrument that oil field at home is used mostly at present is the beam pumping unit of crank balance mode, this kind of pumping unit is all provided with speed reducer, utilize speed reducer to reduce rotating speed and improve moment of torsion, but cause the situation of seal failure very general along with the continuous operation of speed reducer, this not only wastes raw material but also befouling environment, more seriously affect the normal work of pumping unit, reduce oil recovery efficiency and oil production; In addition, due to poorly sealed, tightly the impurity in the speed reducer external world is entered in the fuel tank of speed reducer by rotating shaft, affect the normal work of speed reducer, increase engineering time, impact is produced.
Model utility content
The purpose of this utility model is, for the defect existing in above-mentioned prior art, provides the seal arrangement of a kind of oil pumping unit reduction gearbox of design.
The utility model is achieved through the following technical solutions:
A seal arrangement for oil pumping unit reduction gearbox, comprises bearing cap and gland; It is characterized in that: in the seam of bearing cap center hole, be provided with seal ring, described gland is fixed on bearing cap by the first bolt, described gland lower inside is provided with annulus projection, described annulus projection is vertical with gland, described annulus projection is provided with screw, between described annulus projection and rotating shaft, be provided with dust ring, between described dust ring and annulus projection, be provided with baffle plate, the second bolt is installed in described screw.
Preferably, described seal ring is Polyurethane Wearing Ring.
Preferably, between described the first bolt and gland, be provided with leather packing.
Preferably, the axial thickness of described seal ring is 20mm-30mm.
Preferably, the axial thickness of described dust ring is 25mm-35mm.
The beneficial effects of the utility model are, axial pressure seal ring being produced by annulus projection, thereby make seal ring generation resiliently deformable put aside certain energy, between the axial plane that makes rotating shaft and seal ring, mineralization pressure contacts and realizes sealing, by rotating the second bolt, baffle plate is produced to radial pressure simultaneously, make dust ring be adjacent to rotating shaft, better avoid introduced contaminants by rotating shaft, to enter into the fuel tank of speed reducer; In addition, the utility model design principle is reliable, simple in structure, has application prospect very widely.
Accompanying drawing explanation
Fig. 1 is the seal arrangement embodiment's of oil pumping unit reduction gearbox of the present utility model structural representation.
Fig. 2 is the partial enlarged drawing of A part in Fig. 1.
Fig. 3 is the stereogram of gland in Fig. 1.
