In accompanying drawing, same or analogous reference represents same or analogous parts.
Detailed description of the invention
Following disclosure provides many different embodiments or example for realizing the different structure of the present invention.For letter
Changing disclosure of the invention, hereinafter parts and setting to specific examples are described.Additionally, the present invention can be at different examples
Middle repeat reference numerals and/or letter.This repetition is for purposes of simplicity and clarity, itself does not indicate discussed various
Relation between embodiment and/or setting.It should be noted that, parts illustrated in the accompanying drawings are not drawn necessarily to scale.This
Bright eliminate the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting the present invention.
See Fig. 1, Fig. 1 and show the cross-sectional view of a kind of bearing that the present invention provides.This bearing includes: outer ring
10, inner ring 20, multiple rolling element 30 and retainer 40.
Described inner ring 20, described outer ring 10 and described retainer 40 are loop configuration, and described inner ring 20, described outside
Circle 10 and described retainer 40 are arranged concentrically.
Due to during bearing operation, it will usually produce bigger noise, therefore in outer wall and the institute of described outer ring 10
State and on the outer wall of inner ring 20, be provided with puigging 50.In order to further enhance soundproof effect, it is preferred that in the present invention, use
The double-layer porous deadener that EPDM is formed with butyl rubber prepares puigging 50.And this double-layer porous material not only sound insulation
Effect is more preferable, and the structure that combines of bi-material can make service life of puigging 50 longer.
Between inwall and the outer wall of described inner ring 20 of described outer ring 10, the diameter of the passage of composition is to the end of described bearing
Face is gradually reduced, and forms a passage being similar to taper.The passage of this shape can reduce sonic propagation of making an uproar further.Excellent
Choosing, the angle between the both sides of this tapered channel and inner ring 20 and/or outer ring 20 is 10 °～20 °, under this angle, it is possible to
While realizing noise reduction, ensure that the normal operation of bearing is unaffected, and do not increase production cost.
Being provided with multiple pocket hole on described retainer 40, the long axis in described pocket hole is perpendicular to described retainer 40 place
Plane of rotation.Described rolling element 30 is arranged in described pocket hole.In order to ensure that what rolling element 30 can be stable is arranged in pocket hole,
And do not increase production cost.Preferably, the width of described retainer 40 is 1.2～1.28 times of described rolling element 30 length,
Such as: 1.2 times, 1.25 times or 1.28 times.
Described rolling element 30 is made up of first the 31, second trapezoidal portion 32 of trapezoidal portion and connecting portion 33.Described first trapezoidal portion
31 is identical with the second trapezoidal portion 32 shape and be symmetrical arranged, the bottom surface in described first trapezoidal portion 31 and described second trapezoidal portion 32
It is attached by the bottom surface of connecting portion 33.
Described first trapezoidal portion 31 and described second trapezoidal 32 respectively along being perpendicular to described bearing plane of rotation to described
The both ends of the surface of bearing extend.Described first trapezoidal portion 31 is contacted with interior raceway and outer raceway by the first trapezoidal faces；Described
Two trapezoidal portions 32 are contacted with interior raceway and outer raceway by the second trapezoidal faces.Described first the 31, second trapezoidal portion 32 of trapezoidal portion,
Interior raceway is identical with the radius of curvature of outer raceway, to ensure rolling element 30 and interior raceway, outer raceway perfect adaptation.
Preferably, described interior raceway is provided with at least two groove 300, described outer raceway is provided with at least two
Individual groove 300.Owing to adding groove 300, rolling element adds with the contact position of inside and outside raceway, and bearing can hold simultaneously
By higher radial load and axial load.The results showed, when interior raceway and outer raceway increase by two grooves 300 respectively,
The axial load that bearing can bear improves more than 3 times than the same money bearing not increasing groove.
Preferably, described interior raceway is set to sunk structure 330, described outer raceway with described connecting portion to corresponding part
It is set to sunk structure 330 to corresponding part with described connecting portion.Sunk structure 330 is further with groove 300
Increase the axial load of bearing.Preferably, in described sunk structure, it is provided with solid fraction lubricant, can reduce in bearing operation
Frictional force, increase bearing service life.
In order to increase the service life of bearing, it is to avoid the use of bearing is impacted by dust, it is preferred that in described outer ring
Dust cap 60 it is provided with between 10 and described inner ring 20.
In order to increase the life-span of bearing further, described bearing is copper-based bearings, and bearing material includes: 5%～10%
The bismuth of the nickel of stannum, 3%～7%, 7%～13%, the phosphorus less than 0.1% and the silver less than 1%；Aforementioned proportion is matter
Amount percentage ratio.
After stannum and cuprio matter alloying, there is high intensity, corrosion resistant characteristic.5%～10% is added in copper-based bearings
Stannum, intensity and the wearability of bearing can be increased, the most also avoid the occurrence of the problem that bearing becomes fragile.Nickel can improve axle equally
The intensity held and corrosion resistance, the nickel of 3%～7% can improve the corrosion resistance of bearing, and it is too high to avoid bearing hardness
Problem.The bismuth of 7%～13% can increase the conformal performance of bearing.A small amount of silver can be protected while increasing the corrosion resistance of bearing
Card cost control.A small amount of phosphorus can guarantee that not flashing when bearing has higher corrosion resistance, wear-resistant and impact.
Except using above-mentioned material, it is preferred that described rolling element 30 can also use zirconium oxide and/or silicon oxide ceramics system
Standby.Ceramic material has the advantage that metal material does not possesses, such as: high rigidity, low-density, low-thermal-expansion rate, high resistivity, low
Dielectric constant and being unaffected by the magnetic field.Preferably, zirconium oxide and silicon oxide being combined use, above-mentioned advantage will more
Substantially.
Bearing life length, assembling that the present invention provides are simple, low cost, it is easy to large-scale promotion uses.
Although being described in detail about example embodiment and advantage thereof, it should be understood that without departing from the present invention spirit and
In the case of protection domain defined in the appended claims, these embodiments can be carried out various change, substitutions and modifications.Right
In other examples, those of ordinary skill in the art it should be readily appreciated that while keeping in scope, technique
The order of step can change.
Additionally, the range of application of the present invention is not limited to the technique of specific embodiment described in description, mechanism, system
Make, material composition, means, method and step.From the disclosure, will be easily as those of ordinary skill in the art
Ground understands, for the technique having existed at present or will having developed later, mechanism, manufacture, material composition, means, method or
Step, wherein they perform the knot that the function that is substantially the same of corresponding embodiment or acquisition with present invention description are substantially the same
Really, they can be applied according to the present invention.Therefore, claims of the present invention are intended to these technique, mechanism, system
