Abstract
The utility model relates to a multi-row serial thrust conical roller bearing, comprising a plurality of shaft rings, a plurality of seat rings, a plurality of outer separating rings, a plurality of rollers and a plurality of inner separating rings; the middle part of the inner separating ring is provided with a seat ring fixedly connected with the inner separating ring, the upper part of the seatring is provided with a shaft ring, and a plurality of rollers are installed in a circle between the shaft ring and the seat ring; the outer separating ring is assembled at lower part of the inner separating ring and is fixedly connected with the inner separating ring so that a single thrust roller bearing is formed; and a plurality of thrust roller bearings are connected in series to form the multi-row serial thrust conical roller bearing. The multi-row serial thrust conical roller bearing has scientific, reasonable, creative design, good economical applicability, stability and reliability,thereby solving the lifting force problem of oil pumping electric submersible screw pump and having good development potential. The utility model is suitable for oil extraction in petroleum industry.
Description
Technical field
The utility model relates to a kind of bearing, and what be specifically related to is the multiple row series connection tapered roller thrust bearing that is used on the oil production equipment.
Background technique
Bearing is all used on some equipment of all trades and professions and utensil widely, and at practical situations such as the structural feature of equipment, load that bearing is estimated carrying and Environmental Conditions, it is varied that the kind model of bearing also presents, complete.Tapered roller thrust bearing just belongs to a series in the bearing, though comparatively general tapered roller thrust bearing can bear suitable radial load at present, but to down-hole oil production, can run into various complexity concrete condition such as viscous crude, contain sand, inclined shaft, gas lock and emulsification, this just needs oil production equipment that effective lifting force is provided, and the oil field uses electric submersible screw pump can be competent at this work at present.Yet the bearing on the electric submersible screw pump is import at present.
Being in great demand of this bearing in petroleum industry is to be badly in need of the key issue that solves.
Summary of the invention
The purpose of this utility model is to rely on the present situation of import at the bearing that " electric submersible screw pump " uses, and a kind of multiple row series connection tapered roller thrust bearing is provided.
The technological scheme that adopts is:
Multiple row series connection tapered roller thrust bearing comprises a plurality of blowout patches, a plurality of seat ring, a plurality of outer ring spacer, a plurality of roller, a plurality of cone spacer; The middle part of described cone spacer is provided with seat ring, and seat ring is fixedlyed connected with cone spacer, and the top of seat ring is provided with blowout patche, a plurality of rollers of week installing between blowout patche and seat ring; Outer ring spacer is installed in the bottom of cone spacer and fixedlys connected with cone spacer, constitutes single thrust roller bearing structure; A plurality of thrust roller bearings are composed in series multiple row series connection tapered roller thrust bearing.
Above-mentioned a plurality of roller is coniform.
The top of above-mentioned a plurality of series connection thrust roller bearings is the blowout patche of a thrust roller bearing at top; A plurality of series connection thrust roller bearings bottom is the seat ring of a thrust roller bearing of bottom.
Principle summary:
Multiple row series connection tapered roller thrust bearing is the bearing that is exclusively used in the oil pumping electric submersible screw pump.Electric submersible screw pump is the screw-pump oil-extraction equipment that the down-hole oil-submersible motor drives, this oil production equipment is handled many difficulties that meet at oilfield engineering and is adopted situation (as viscous crude, contain sand, inclined shaft, gas lock and emulsification) design and make, and effective lifting force can be provided greatly.
Electric submersible screw pump is the oil tool that a kind of radial dimension is little, load-carrying ability is big.Produce very big axial force owing to go out on the screw rod of well when work rotation, radial dimension is little, has limited the size of thrust-bearing, therefore has to adopt the thrust-bearing of one group of a plurality of less external diameter to be shared and bears axial force.The bearing of this kind high load is made of a plurality of identical non-standard thrust conical bearings and cone spacer therebetween, outer ring spacer series connection.Each tapered roller thrust bearing should be born line shaft more equably to load, and this is the big key of multiple row series connection tapered roller thrust bearing group weight bearing power.
Advantage of the present utility model is:
Multiple row series connection tapered roller thrust bearing is owing to be that a plurality of series connection tapered roller thrust bearings are combined into an integral body, thrust-bearing with a plurality of less external diameters is shared the axially bigger power of bearing, make each tapered roller thrust bearing of multiple row bear line shaft more equably to load, improved working efficiency, energy efficient, and good operating stability, installation and removal are convenient in addition, avoid the damage of axle simultaneously.
The utility model design science, reasonable, original, economic serviceability is strong, reliable and stable, adequate solution the oil pumping electric submersible screw pump the lifting force problem, have development prospect preferably.The utility model is applicable to petroleum industry oil recovery use.
