Abstract
The utility model relates to a thrust and straightening double-functional wear resistant bearing of a submersible pump, which comprises an upper bearing assembly and a lower bearing assembly. The upper bearing assembly and the lower bearing assembly are arranged together by a shaft; the upper bearing assembly comprises an upper bearing seat and an upper thrust bearing arranged on the upper bearingseat; the lower bearing assembly comprises a straightening bearing inner ring, a straightening bearing outer ring and a lower bearing seat which are subsequently arranged on the shaft; the lower thrust bearing is arranged on the lower bearing seat; and an upper bearing contacts with a lower bearing. The thrust and straightening double-functional wear resistant bearing of the submersible pump is characterized by the double functions of axial thrust and radial straightening, action of a static block and a dynamic block, simple structure, small occupied space, convenient installation, wear resistance and the like, and is widely applied to submersible pumps and similar equipment.
Description
One, technical field
The utility model relates to the submersible electric pump bearing, and difunctional anti-friction bearing is set upright in particularly a kind of submersible electric pump thrust.
Two, background technique
Being applied in the electric pump manufacturing of pump inner bearing accounting for critical role, traditional electric pump bearing is along with Oilfield developing, the sand production situation is more and more serious, under the trend of oil field to the discharge capacity requirement of electric pump, therefore cause the inefficiency of electric submersible pump, service life is of short duration, causes great economic loss.The thrust washer of bearing often under weight the problem of premature failure highlight.
Three, summary of the invention
The purpose of this utility model provides a kind of submersible electric pump thrust and sets upright difunctional anti-friction bearing, adopt up and down assembly and set upright coil structures and high-abrasive material, make bearing possess thrust with set upright difunctional, and improved wear-resisting property, prolonged the working life of bearing, thereby made the unit operation time more lasting.
Difunctional anti-friction bearing is set upright in submersible electric pump thrust described in the utility model, comprise upper bearing assembly and lower bearing assembly, it is characterized in that described upper bearing assembly and lower bearing assembly are installed together by axle, the upper bearing assembly comprises upper axis bearing and the top thrust bearing that is mounted thereon, the lower bearing assembly comprises alignment bearing inner ring, alignment bearing outer ring and the lower shaft bearing that is installed in turn on the axle, the bottom thrust bearing is installed on the lower shaft bearing, and upper bearing contacts with lower bearing.
Wherein, described upper bearing assembly is corresponding with the lower bearing assembly to be installed on the axle, and upper bearing and lower bearing contact with rolling.
The utility model has the following advantages compared with prior art:
1,, and, this bearing is become possess axial thrust and radially set upright double-acting wear-resisting " O " type structure at friction vice division chief employing high-abrasive material by design to the lower bearing stand structure.
2, the bottom thrust bearing is embedded in the lower shaft bearing, to realize quiet effect of bottom thrust bearing.Lower shaft bearing, alignment bearing outer ring and the acting in conjunction of alignment bearing inner ring, the radially centralizing function of realization bearing.
3, lower shaft bearing, alignment bearing outer ring and the acting in conjunction of alignment bearing inner ring, the radially centralizing function of realization bearing; Simultaneously the lower shaft bearing is embedded in the bottom thrust bearing again, thereby makes the bottom thrust bearing play quiet effect in the process of axial thrust.
4, the top thrust bearing is embedded in the upper axis bearing, the upper axis bearing links together by key and axle, the upper axis that is in operation bearing is followed axle jointly with the top thrust bearing and is rotated, thereby makes the top thrust bearing play the effect of motion block in the thrust process.
5, simple in structure, have simultaneously and set upright and two kinds of functions of thrust.
6, that bearing is taken up space is little for integration of function, simple installation.
7, adopt high-abrasive material, strengthened the wear-resisting property of body, effectively prolonged bearing working life.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic representation of the present utility model.
Five, embodiment
Consult accompanying drawing, difunctional anti-friction bearing is set upright in a kind of submersible electric pump thrust, comprises upper bearing assembly and lower bearing assembly.Upper bearing assembly and lower bearing assembly are installed together by axle 7, the upper bearing assembly comprises upper axis bearing 1 and the top thrust bearing 2 that is mounted thereon, the lower bearing assembly comprises alignment bearing inner ring 6, alignment bearing outer ring 5 and the lower shaft bearing 4 that is installed in turn on the axle 7, bottom thrust bearing 3 is installed on the lower shaft bearing 4, and top thrust bearing 2 contacts with bottom thrust bearing 3.
The upper bearing assembly is corresponding with the lower bearing assembly to be installed on the axle 7, and top thrust bearing and bottom thrust bearing contact with rolling.
Claims (2)
1, difunctional anti-friction bearing is set upright in a kind of submersible electric pump thrust, comprise upper bearing assembly and lower bearing assembly, it is characterized in that described upper bearing assembly and lower bearing assembly are installed together by axle, the upper bearing assembly comprises upper axis bearing and the top thrust bearing that is mounted thereon, the lower bearing assembly comprises alignment bearing inner ring, alignment bearing outer ring and the lower shaft bearing that is installed in turn on the axle, the bottom thrust bearing is installed on the lower shaft bearing, and upper bearing contacts with lower bearing.
2, difunctional anti-friction bearing is set upright in submersible electric pump thrust according to claim 1, it is characterized in that described upper bearing assembly is corresponding with the lower bearing assembly to be installed on the axle, and upper bearing and lower bearing contact with rolling.
