Abstract
The utility model relates to a high low temperature motor bearing, including outer lane, inner circle, rolling element, first holder and second holder, outer lane and inner circle are connected to the rolling element to with first holder and second holder location, make the rolling element evenly part, the outer lane width is the same with the inner circle width, wherein, outer lane and inner circle all adopt 9Cr18 stainless steel material, the utility model has the advantages of simple and compact structure rationally, have better rust -preventing characteristic ability, optimized bearing material and structure under the prerequisite of guaranteeing high low temperature motor bearing rotational speed, life requirements to resistant high and low temperature performance of bearing and wear resistance have been improved.
Description
Technical field
This utility model is related to a kind of bearing, especially a kind of high/low temperature motor bearings, be mainly used in novel high-definition cleanliness,
On the armarium motor of high/low temperature sterilization, belong to medical electric machine part technical field.
Background technology
It is presently used for high/low temperature motor bearings on general medical equipment motor mainly by outer ring, inner ring, retainer, rolling
Kinetoplast, metal dust-proof cover and grease etc. form.Using installing rolling element between outer ring and inner ring, with retainer positioning, protect
Hold the uniform separation roller of frame and holding rolling element proper exercise, two panels metal dust-proof cover is put in the dustproof groove of outer ring respectively
Interior, play dust-proof and prevent oils and fatss from leaking outside, grease plays lubrication it is therefore an objective to make to be formed one between bearing element face and sliding surface
The very thin oil film of layer, to prevent metal and metal directly contact, thus reducing Bearing inner friction and abrasion, preventing from burning and gluing.
But in high/low temperature motor in the prior art, motor high ambient temperature reaches 250 DEG C, during as little as -196 DEG C of low temperature,
Problems with can be run into：1st, medical motor bearings rustless property is poor, easily gets rusty；2nd, plain bearing steel matter bearing ring is installed
After cannot bear 250 DEG C of high temperature and -196 DEG C of low temperature, lead to bearing material metallographic structure under such environment to change rapidly
Lost efficacy；3rd, oils and fatss are not had can to bear 250 DEG C of high temperature and -196 DEG C of low temperature；4th, because the temperature difference is larger, the material of metal dust-proof cover
Different from lasso material dilation rate will be made different, metal dust-proof cover will be occurred in inner-outer sleeve stuck in temperature change
Phenomenon in collar dustproof groove, leads to bearing failure.
Content of the invention
In order to solve the deficiencies in the prior art, this utility model provides a kind of high/low temperature motor bearings, passes through
Optimization improves bearing each parts material and structure reaches this high/low temperature medical treatment motor performance requirement it is ensured that bearing is in high/low temperature ring
Use in border.
The technical scheme that this utility model is taken is as follows：A kind of high/low temperature motor bearings, including outer ring, inner ring, rolling element,
First retainer and the second retainer, described rolling element connects outer ring and inner ring, and fixed with the first retainer and the second retainer
Position, makes rolling element uniformly separately, described outer ring width is identical with inner race width, and wherein, described outer ring and inner ring are all using 9Cr18
Stainless steel material.
Further, the material of described rolling element is Si3N4 Ceramic Balls.
Further, described first retainer and the second retainer are all using 0Cr18Ni9 stainless steel material.
The beneficial effect that this utility model reaches is：This utility model structure is simple, compact and reasonable, has preferably antirust
Performance, optimizes bearing material and structure, thus improve on the premise of guarantee high/low temperature motor bearings rotating speed, life requirements
Bearing high and low temperature resistance and anti-wear performance.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure, 1, outer ring, 2, inner ring, 3, rolling element, the 4, first retainer, the 5, second retainer.
Specific embodiment
Below in conjunction with brief description and specific embodiment, this utility model is described in further detail：
As shown in figure 1, a kind of high/low temperature motor bearings, including outer ring 1, inner ring 2, rolling element 3, the first retainer 4 and
Two retainers 5, described rolling element 3 connects outer ring 1 and inner ring 2, and is positioned with the first retainer 4 and the second retainer 5, makes rolling
Uniformly separately, described outer ring 1 width is identical with inner ring 2 width, and wherein, described outer ring 1 and inner ring 2 are all stainless using 9Cr18 for body 3
Steel material.
This 9Cr18 stainless steel material has good rustless property, increases -70 in 9Cr18 stainless steel material heat treatment
Freezing in 2 hours below DEG C and the tempering in 3 hours of 300 DEG C of temperature, to improve the rustless property of bearing, and to ensure to use in high/low temperature
The stable material quality of environment.
Further scheme is that the material of described rolling element 3 is Si3N4 Ceramic Balls, instead of grease using it is ensured that
Stable material quality under this high and low temperature environment for the bearing and anti-wear performance, make bearing in the ring of 250 DEG C of high temperature and -196 DEG C of low temperature
Being capable of safe operation under border.
Further scheme is that described first retainer and the second retainer are all using 0Cr18Ni9 stainless steel material.
This utility model, compared with existing high/low temperature motor bearings, employs the open architecture of no metal dust-proof cover, moves
Except metal dust-proof cover, eliminate outer ring and interior collar dustproof groove structure it is ensured that high/low temperature huge poor lower bearing running simultaneously
Motility.
This utility model structure is simple, compact and reasonable, on the premise of guarantee high/low temperature motor bearings rotating speed, life requirements
Optimize bearing material and structure, thus improve the performance of bearing high-low temperature resistant.
Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect
Step describes in detail, be should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model.This utility model expands to any new feature disclosing in this manual or any new combination, and discloses
Arbitrary new method or the step of process or any new combination.
