Abstract
The invention belongs to the field of petroleum machinery and relates to a stainless steel non-magnetic bearing. The stainless steel non-magnetic bearing comprises an inner ring, an outer ring and a holder. The outer ring sleeves the holder. The inner circumference of the holder sleeves the inner ring. The holder comprises a first-grade sub-holder and a second-grade sub-holder. An annular groove is arranged between the first-grade sub-holder and the second-grade sub-holder. Two side walls of the annular groove are provided with multiple first-grade grooves. The inner walls of the first-grade sub-holder and the second-grade sub-holder for supporting steel balls are communicated through the first-grade groove and the annular groove. The stainless steel non-magnetic bearing is provided with the annular groove so that lubrication oil can be stored between the first-grade sub-holder and the second-grade sub-holder. Through the first-grade groove, the steel balls are lubricated by grease. Each one of the steel balls is provided with multiple pits for storing graphite so that when grease is deficient, graphite has steel ball lubrication effects and thus a lubrication capability is improved.
Description
Technical field
The invention belongs to field of petroleum machinery, particularly relate to a kind of rustless steel no-magnetism bearing.
Background technology
In whole submersible electric machine with oil industry, be introduced into China from 1985 from radar company of the U.S., the complete GCr15 alignment bearing of use, it in use need stator steel disc to be used relative to place with rotor and centralizer as isolation magnetic field.Along with the progress of science and technology, more and more higher to the performance requirement of equipment, work condition environment is harsher, and general no-magnetism bearing requires that the maximum friction moment of bearing is less than 0.4g/cm in the environment of high-intensity magnetic field.By to the process technology research of no-magnetism bearing steel and the exploration of Technology for Heating Processing, develop that meet user's request and annual production 4000 can be formed overlap bearing production capacity, but it is inadequate that existing no-magnetism bearing shortcoming is lubricating ability, usually cause because of fretting wear losing efficacy.
Summary of the invention
It is an object of the invention to for above-mentioned deficiency present in prior art, a kind of rustless steel no-magnetism bearing is proposed, this bearing is provided with annular groove, making lubricating oil can be stored in one-level to divide between retainer and two fraction retainers, and make grease be lubricated steel ball by first recess, steel ball is provided with multiple pit simultaneously, in order to deposit graphite, when making grease deficiency, steel ball is played lubrication by graphite, thus improves lubricating ability.
The present invention solves it and technical problem is that and realize by the following technical solutions:
A kind of rustless steel no-magnetism bearing, including inner ring, outer ring, retainer, described outer ring be placed on retainer, periphery on, the inner circumferential of described retainer is placed on the periphery of inner ring, described retainer includes that one-level divides retainer and two fraction retainers, described one-level is divided and is provided with annular groove between retainer and two fraction retainers, being equipped with multiple first recess on the two side of described annular groove, the one-level of supported steel ball divides the inwall of retainer and two fraction retainers all to be communicated with annular groove by first recess；
Described one-level is divided and is laid with multiple steel ball on retainer and two fraction retainers, and the periphery wall of described steel ball is provided with multiple equally distributed pit, is filled with graphite in described pit, and described graphite-filled pit outer surface is equal with the outer surface of steel ball.
Further, the outer wall of described outer ring is provided with lubricant grease mouth, and a sidewall of described lubricant grease mouth is provided with rotational pin, and described rotational pin is provided with cover plate, the side of described cover plate is provided with projection, and another sidewall of described lubricant grease mouth is provided with the second recess matched with projection.
Further, described inner ring and outer ring are annular.
Further, described inner ring and outer ring all use non-magnetic alloy steel.
Compared with prior art, the beneficial effect comprise that: a kind of rustless steel no-magnetism bearing is provided, this bearing is provided with annular groove, make grease can be stored in one-level and divide between retainer and two fraction retainers, and make grease that steel ball to be lubricated by first recess, steel ball is provided with multiple pit simultaneously, in order to deposit graphite, when making grease deficiency, steel ball is played lubrication by graphite, two kinds of lubrications of summary, the lubricating ability making rustless steel no-magnetism bearing is improved, and inner ring and outer ring all use non-magnetic alloy steel, change in size the most also will not occur.
