Abstract
The utility model relates to a radial rolling bearing seat assembly structure with good vibration absorption performance, which comprises a bearing seat, a radial rolling bearing composed of an inner ring, an outer ring, a rolling body and a retainer and with an axial stopping groove and a metal element vibration absorption ring. The inner ring is matched with a shaft and rotates with the shaft. The metal element vibration absorption ring is arranged between the bearing seat and the outer ring of the radial rolling bearing. A U-shaped outer edge and a bottom edge rotate with the central line of the shaft as a rotating centre to form the outside and the bottom of the vibration absorption ring, a U-shaped inner edge rotates intermittently at equal clearances at the same rotating centre to form the inside of the vibration absorption ring, and accordingly the vibration absorption ring with a petal-like body on the inside and roughly in a shape of a rotating body is formed. The pedal-like body is provided with equal central angle notches. The outside of the vibration absorption ring is matched and tightly fixed with the bearing seat, a protrusion on the pedal-like body of the vibration absorption ring is embedded and limited in the axial stopping groove of the radial rolling bearing. The radial rolling bearing seat assembly structure is good in vibration absorption performance and low in working noise. The bearing of the radial rolling bearing seat assembly structure is long in service life.
Description
Technical field
The utility model relates to field of mechanical technique, particularly relates 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 utility model aims to provide a kind of annular bearing with rolling contact seat assembly structure with good vibration damping.
Technical solution of the present utility model 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 utility model 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 utility model is with low cost, and is easy to assembly.
Description of drawings
Below with reference to drawings and Examples the utility model is described in further details:
Accompanying drawing 1 is the utility model embodiment's a structural representation.
