Description

Annular bearing with rolling contact seat assembly structure with good vibration damping
Technical field
The present invention relates to field of mechanical technique, particularly relate to a kind of annular bearing with rolling contact seat assembly structure with good vibration damping
Background technique
In the prior art, annular bearing with rolling contact generally is made up of inner ring, outer ring, rolling element and retainer four parts, and in most cases, its inner ring matches to merge with axle and rotates together with the axis; Matching with bearing support in the outer ring, plays a supportive role; Rolling element is evenly distributed between inner ring and the outer ring by means of retainer, and retainer can make rolling element evenly distribute, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.The rolling bearing working service is convenient, reliable operation, and starting performance is good; Its deficiency is that the damping capacity of annular bearing with rolling contact seat of prior art is relatively poor, to being installed on the structure of the used annular bearing with rolling contact seat of some rotor on the vehicles such as automobile, remove the extraneous vibration power of the dynamic unbalance of bear rotor self rotation generation, it also is subjected to the instantaneous impact that random stochastic vibration produces in the vehicle driving process of place, the impact force of especially instantaneous dither, cause bearing roller to strengthen at double with the pressure stress that contacts of Internal and external cycle, damage to bearing is very big, cause axle sound when high speed rotating bigger, bearing life is low, needs bearing block structure is improved
Summary of the invention
The present invention aims to provide a kind of annular bearing with rolling contact seat assembly structure with good vibration damping.
Technical solution of the present invention is as follows:
A kind of annular bearing with rolling contact seat assembly structure, comprise bearing support, by inner ring, the outer ring, the annular bearing with rolling contact that rolling element and retainer four parts are formed, described inner ring matches to merge with axle and rotates together with the axis, it is characterized in that: it also comprises damping ring, this damping ring is installed between bearing support and the annular bearing with rolling contact outer ring, described damping ring is a metalwork, its outside and bottom are that the rotating center rotation forms by the outside of U-shaped and base with the center line of axle, its inboard by the inner edge of U-shaped with the center line of axle be rotating center intermittently rotation intermittently form, thereby form the metalwork that roughly is solid of rotation that there is rosette evenly spaced apart an inboard, the central angle breach such as have between each rosette, the outside of damping ring and bearing support match to merge and tighten up, and each rosette of damping ring inboard all matches with the annular bearing with rolling contact outer ring.
The present invention is owing to adopt technique scheme; the random vibration power that the rosette of damping ring inboard is subjected to when effectively buffer shaft is worked; significantly alleviate its injury to axle and bearing; especially significantly alleviated of the infringement of the instantaneous impact of dither formation to axle and bearing; reduced operating noise; protect axle and bearing simultaneously, improved their operating life, realized goal of the invention easily.
Further technological scheme is:
The projection of each all oriented above-mentioned rotating center direction in rosette upper end of described damping ring inboard, described annular bearing with rolling contact has the axial retention groove on the outer ring, and the projection of described each rosette upper end all is limited in the above-mentioned axial retention groove.
Technique scheme plays the axial limiting effect, has guaranteed the axially locating of damping ring with respect to annular bearing with rolling contact.
Further technological scheme is again:
The rosette number of described damping ring inboard is more than or equal to 5.
Adopt the rosette more than 5 or 5 to disperse the suffered instantaneous impact of single rosette, the shock-absorbing capacity that improves rolling bearing pedestal is had positive meaning.
Adjust quantity, thickness, material and the heat treatment parameter thereof of rosette, can make the vibration parameters (elasticity coefficient) of rosette more reasonable.
The shared central angle of the shared central angle of above-mentioned rosette and breach is to equate for good.
Each rosette of above-mentioned damping ring inboard and annular bearing with rolling contact outer ring are transition fit or stationary fit.
Further technological scheme is again:
The shared central angle of locating with the connecting part at the bottom of the damping ring of rosette increases gradually, makes each rosette be similar to and is the isosceles trapezoid shape.This measure helps improving the intensity of rosette root.
The present invention is with low cost, and is easy to assembly.
Description of drawings
Below with reference to drawings and Examples the present invention is described in further details.
Accompanying drawing 1 is the structural representation of the embodiment of the invention.
Each sequence number is respectively among the figure: 1, bearing support; 2, the damping ring outside; 3, the inboard rosette of damping ring; 4, inboard breach; 5, damping ring bottom; 6, projection; 7, annular bearing with rolling contact outer ring; 8, axial retention groove; 9, axle.
Embodiment
Referring to accompanying drawing 1, a kind of annular bearing with rolling contact seat assembly structure shown in the embodiment of the invention, form by bearing support 1, damping ring, annular bearing with rolling contact, axle 9, annular bearing with rolling contact is made up of inner ring, outer ring 7, rolling element and retainer four parts, has axial retention groove 8 on the annular bearing with rolling contact damping ring outer ring 7.The annular bearing with rolling contact inner ring matches with axle 9 and merges and axle 9 rotations.Damping ring forms integrative-structure by the damping ring outside 2, damping ring bottom 5, the inboard rosette 3 of damping ring, and the inboard rosette of damping ring is totally 10 among this embodiment.This damping ring is a metalwork, it is installed between bearing support 1 and the annular bearing with rolling contact outer ring 7, its outside 2 and bottom 5 are that the rotating center rotation forms by the outside of U-shaped and base with the center line of axle respectively, its inboard by the inner edge of U-shaped with the center line of axle be rotating center intermittently rotation intermittently form, thereby form the metalwork that roughly is solid of rotation that there is rosette 3 evenly spaced apart an inboard, central angle breach 4 such as have between each rosette, the shared central angle of the shared central angle of above-mentioned rosette and breach equates, the projection 6 of all oriented above-mentioned rotating center direction in the upper end of each rosette, the outside 2 and the bearing support 1 of damping ring matches to merge and tightens up, each rosette of damping ring inboard all with annular bearing with rolling contact outer ring 7 transition fit, and the projection 6 of each rosette upper end all embeds and is limited in the above-mentioned axial retention groove 8, has guaranteed the axially locating of damping ring with respect to annular bearing with rolling contact.
