Description

A kind of big channel can bore thrust bearing
Technical field
The present invention relates to a kind of big channels can bore thrust bearing, belongs to oil, natural gas drill and petroleum extraction tools technical field.
Background technology
Turbine guide shoe tool is a kind of Novel down-hole casing pipe running device converting mud liquid energy to mechanical energy, and mud energy It is no efficiently to rapidly flow through the service life that thrust bearing group directly affect completion efficiency and tool.In addition in actual use process In, turbine guide shoe tool can be influenced by factors such as high temperature, burn into salt crust, foulings, if too long in the underground work time, The thrust bearing, alignment bearing, turbine of enclosure interior can be made to deform, or even meeting clamping stagnation is inside housings, result must not be exactly Special equipment is not employed to be salvaged.If can not salvage, it is possible to cause oil well to scrap, bring larger economic loss. Therefore, it is necessary to research and develop a kind of thrust bearing with slurry channel, mud can be allowed to directly flow through bearing through channel, made in completion It need not be also drawn off after industry, bore mill off, thrust bearing is bored to greatly improve completion efficiency.
Invention content
It is an object of the invention to:Offer is a kind of simple in structure, and practicability is good, and larger axial direction can be born in the course of work Load, and slurry liquid passing through rapidly and efficiently can be made, it can effectively ensure that operation of the turbine guide shoe under high-speed condition, and complete The big channel of guide shoe brill mill efficiency can bore thrust bearing after well operations.
The technical scheme is that:
A kind of big channel can bore thrust bearing, it is made of the multiple bearing units being arranged in order, and each bearing unit includes rolling Body, inner ring and outer ring, it is characterised in that:Inner ring, the both sides of the both sides and inner ring outer surface of inner surface are set in outer ring It is in the arc groove that symmetry shape is provided with annular, the arc groove between adjacent bearing unit by being arranged on outer ring and inner ring respectively Mutual cooperation constitute ring raceway, be movably installed with multiple rolling elements in ring raceway;The outer ring of the arc groove periphery of outer ring It is respectively arranged with annular diversion trench on the end face of both sides, multiple fluid courses are evenly equipped on the circumference of annular diversion trench.
Its radius is equal between arc groove on the outer ring and inner ring.
The fluid course quantity is 4.
The rolling element is made of the ball of ceramic material, and the ball quantity in ring raceway is 15-18.
The beneficial effects of the invention are as follows:
(1)The thrust bearing has good self lubricity and Wear-resistant, high-temperature resistant performance, can be good at adapting to underground working.
(2)Diversion trench on the thrust bearing end face can effectively guide slurry liquid to enter fluid course, then quickly through Bearing, and pressure drop is influenced small.
(3)Assembly can be adjusted flexibly in the thrust bearing pair number according to field demand, to provide different carryings.
(4)The thrust bearing structure is ingenious in design, be easily installed, large carrying capacity, simple in structure, efficient.
(5)The bearing is not required to specific purpose tool and is drawn off, salvages after completion practice, bores mill off, avoids because of work Tool deformation causes wellbore to block, and saves duty cycle and activity duration.
(6)The ring raceway of the bearing is by passing through the arc groove that is arranged on outer ring and inner ring between adjacent bearing unit It cooperates and constitutes, make to form four point contacts between rolling element and inside and outside raceway, it is negative to which larger axial direction can be born Load forces increase rated load, improve impact resistance, effectively reduce abrasion, extend bearing service life.

Specific implementation mode
The big channel can bore thrust bearing and is made of the multiple bearing units being arranged in order, and each bearing unit includes rolling element 1, inner ring 2 and outer ring 3 are set with inner ring 2, inner ring 2 and outer ring 3 in outer ring 3 using material manufacture is easily bored, such as Sn-Al alloy, casting The nylon etc. of iron, brass and the additive containing glass, Sn-Al alloy, brass and cast iron have a good casting character, and its wearability, Corrosion resistance and high temperature resistance are good;Nylon material is high molecular polymer, its thermostabilization after glass and fire retardant is added Performance and other physical properties, which are obtained for, to be substantially improved, and its wearability, excellent corrosion resistance, ceramic rolling element have very well Self lubricity, in dry friction, fluid friction and mixed film friction, working performance is excellent, can well adapt to underground working.
The both sides of 2 outer surface of both sides and inner ring of 3 inner surface of outer ring are in the arc groove 4 that symmetry shape is provided with annular respectively, Its radius is equal between arc groove 4 on outer ring 3 and inner ring 4.By being set on outer ring 3 and inner ring 2 between adjacent bearing unit The mutual cooperation for the arc groove 4 set constitutes ring raceway, and the arc groove 4 and the center of circle of the arc groove 4 on inner ring 2 on outer ring 3 exist On the same circumference of ring raceway.
15-18 rolling elements 1 are movably installed in ring raceway;Rolling element 1 is made of the ball of ceramic material, is rolled It is contacted for four-point between body 1 and ring raceway.1 Ceramics material of rolling element has good self lubricity, without glossy Work has the characteristics that have excellent performance when sliding.
It is respectively arranged with annular diversion trench 5, annular diversion trench on the end face of 3 both sides of outer ring of 4 periphery of arc groove of outer ring 3 4 fluid courses 6 are evenly equipped on 5.The purpose of 4 fluid courses 6 is set, first, ensureing inflow-rate of water turbine, second is that ensureing the diameter of outer ring 3 To the intensity of support force, its intensity is avoided to be affected, that is, under the premise of not influencing intensity, to improve inflow-rate of water turbine as possible, solve Existing raising inflow-rate of water turbine and the problem of influence radial support power intensity.
When the big channel can bore thrust bearing assembly, it is sleeved on turbine wheel shaft by the inner ring 2 of each bearing unit, both ends It is fixed respectively by baffle device.In the course of work, work as mud(Drilling fluid)When entering the thrust bearing through baffle device, Most of mud is through fluid course 6 quickly through fraction mud enters in annular diversion trench 5, into annular diversion trench 5 For mud under the guiding of annular diversion trench 5, mud can be quickly through fluid course 5, to be integrally improved inflow-rate of water turbine, and effectively Reduce pressure drop difference.
The big channel, which can bore thrust bearing, can bear larger axial load, slurry liquid can be allowed fast by fluid course 6 Speed efficiently passes through the thrust bearing;Simultaneously as bearing use can bore material and be made, have the characteristics that drillability is excellent, To ensure that the efficient operation under high-speed condition, and the brill of guide shoe grinds efficiency after completion practice, and then solves Existing turbine guide shoe salvages difficulty, and brill milling difficulty is big, and can bearing lubrication and slurry liquid asking quickly through thrust bearing group Topic has positive meaning to oil, natural gas drilling operation.
