Abstract
Rust -resistant open type bearing, including bearing inner race, bearing inner race, holder, rolling element, the holder is located between bearing inner race and the bearing inner race, the rolling element is located on the holder, the rolling element takes place to roll and then drives the holder and rotates, in the rotational clearance between holder and bearing inner race, the bearing inner race and the rolling element between rolling interval in all fill and have emollient, the utility model discloses rust -resistant open type bearing, bearing inner race, outer lane, rolling element are made by 440 stainless steel material, and the holder adopts 66 materials of increase nylon to make, and all material homoenergetics are rust -resistant, the utility model has the advantages of simple structure, intensity height and precision are high, rust -resistantly lose, corrosion resistance is good, be applicable to the humidity, under water wait easy corrosion, corrode work in the media environment by force, extensive applicability, the practicality is strong.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of antirust open bearing.
Background technique
Bearing rises fixing in mechanical transmission course and reduces the parts of load friction factor, alternatively, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.
When general working environment and higher rotation speed work, bearing adopts that dust cover is dust-proof usually, seal ring sealing, and Internal and external cycle and steel ball adopt Bearing Steel manufacture.When working environment is poor, adopt rubber seal rings for seal to the higher occasion of seal request, bearing just can not be on active service for a long time, and especially bearing is applied in bathroom when doing pulley use, and often to touching water vapour, bearing can not meet antirust requirement.
Summary of the invention
The purpose of this utility model is problem that can not be antirust for plain bearing, provides that a kind of rustless property is good, the antirust open bearing of long service life.
The technological scheme that the utility model solves the problems of the technologies described above and adopts is: antirust open bearing, comprise bearing outer ring, bearing inner race, retainer, rolling element, described retainer is located between bearing outer ring and bearing inner race, described rolling element is located on retainer, described rolling element occurs to roll and then drive retainer to rotate, in running clearance between described retainer and bearing outer ring, bearing inner race and and rolling element between rolling gap in be all filled with oiling agent, it is characterized in that: described rolling element is Stainless Steel Ball, is made up of 440 stainless steels.
As improvement, described bearing outer ring and bearing inner race are made by 440 stainless steels, the madial wall of described bearing outer ring is provided with the rolling surface for rolling element running, the outer side wall of described bearing inner race is provided with the rolling surface for rolling element running, and the gap between described rolling surface and rolling element is 0.0013-0.002mm.
As improvement, described retainer adopts increase nylon 66 material to make.
As improvement, described oiling agent is lubricant oil or lubricating grease, and filling out fat amount is 0.12-0.18g.
Compared with prior art, the utility model has the advantage of: adopt technique scheme, the antirust open bearing of the utility model, bearing inner race, outer ring, rolling element are made by 440 stainless steel materials, retainer adopts increase nylon 66 material to make, and all material all can be antirust; Structure of the present utility model is simple, and intensity is high and precision is high, and anti-corrosion, corrosion resistance are good, and be applicable to work in humidity, easy-to-rust, the deep-etching media environment such as under water, applicability is wide, practical.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Antirust open bearing as described in Figure 1, comprise bearing outer ring 1, bearing inner race 2, retainer 3 and rolling element 4, described retainer 3 is located between bearing outer ring 1 and bearing inner race 2, described rolling element 4 is located on retainer 3, described rolling element 4 occurs to roll and then drive retainer 3 to rotate, in running clearance between described retainer 3 and bearing outer ring 2, bearing inner race 1 and and rolling element 4 between rolling gap in be all filled with oiling agent, it is characterized in that: described rolling element 4 is Stainless Steel Ball, is made up of 440 stainless steels.Described bearing outer ring 1 and bearing inner race 2 are made by 440 stainless steels, the madial wall of described bearing outer ring 1 is provided with the rolling surface 11 operated for rolling element 4, the outer side wall of described bearing inner race 2 is provided with the rolling surface 21 operated for rolling element 4, and the gap between described rolling surface and rolling element is 0.0013-0.002mm.Described retainer 3 adopts increase nylon 66 material to make.Described oiling agent is lubricant oil or lubricating grease, and filling out fat amount is 0.12-0.18g.
The antirust open bearing of the utility model, bearing inner race, outer ring, rolling element are made by 440 stainless steel materials, and retainer adopts increase nylon 66 material to make, and all material all can be antirust; Structure of the present utility model is simple, and intensity is high and precision is high, and anti-corrosion, corrosion resistance are good, and be applicable to work in humidity, easy-to-rust, the deep-etching media environment such as under water, applicability is wide, practical.
Above disclosedly be only a kind of preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
