Abstract
A kind of semi-rigid steering bearing, belongs to rolling bearing field.The problem of attached raceway existence and stability difference of existing semi-rigid steering bearing, the utility model includes inner ring, retainer, rolling element and outer ring assembly, inner ring periphery is provided with outer raceway, outer ring assembly includes outer ring case, elastomer and two attached raceway bodies, two attached raceway bodies are relative and put and be positioned in the case of outer ring, attached raceway body is in annular, contacted on the outside of each attached raceway body between the inner surface of the casing of outer ring for face, annular circular arc concave surface is equipped with the inside of each attached raceway body, two annular circular arc concave surfaces are combined into is engaged raceway in corresponding with outer raceway, rolling element supports cooperation to be installed between interior raceway and outer raceway by retainer, elastomer is built in the outer ring case and forms axial pressing to one of them attached raceway body.The utility model stability is good, can reduce caused noise in bearing working, extend bearing service life.
Description
Technical field
The utility model belongs to rolling bearing field, especially relevant with a kind of semi-rigid steering bearing.
Background technology
The utility model patent of Application No. 200990100506.2 discloses a kind of rolling for car steering tube column
Bearing arrangement, is a kind of semi-rigid steering bearing, and the rolling bearing system includes outer ring, inner ring and is positioned at outer ring and inner ring rolling
At least row's rolling element between road, outer ring includes housing, the ring-type of two positioning in the housing attaches raceway and is pressed against shell
The elastic ring of body and one of them attached raceway.The attached rolling track and radial section is rounded, attach raceway and shell inner surface it
Between be linear contact lay, because its contact area is smaller, attach that raceway stability is poor, and bearing easily produces bounce in the course of the work,
It is also easy to produce noise simultaneously.
Utility model content
The purpose of this utility model is intended to overcome the traditional semi-rigid steering bearing for being currently used for steering column for vehicles support attached
Even the defects of raceway stability difference, there is provided a kind of special semi-rigid steering bearing of the preferable car steering tube column of stability.
Therefore, the utility model uses following technical scheme：A kind of semi-rigid steering bearing, including inner ring, retainer, rolling
Kinetoplast and outer ring assembly, inner ring periphery are provided with outer raceway, it is characterized in that, the outer ring assembly includes outer ring case, elastomer
With two attached raceway bodies, two attached raceway bodies are relative and put and be positioned in the case of outer ring, and attached raceway body is in annular,
Contacted on the outside of each attached raceway body between the inner surface of the casing of outer ring for face, annular circle is equipped with the inside of each attached raceway body
Arc concave surface, two annular circular arc concave surfaces are combined into is engaged raceway in corresponding with the outer raceway, and rolling element passes through the guarantor
Hold frame support cooperation to be installed between the interior raceway and outer raceway, the elastomer is built in the outer ring case and to it
In an attached raceway body form axial pressing.
As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
The attached raceway body radial outside makes it be contacted between the outer ring the inner surface of the casing for face into the face of cylinder.
The outer ring case both ends all set radially inner turn-up portion, and axial limit is formed to described attached raceway body
Position, wherein the turn-up portion of one end is axially bent to form the accommodating cavity for housing the elastomer, and the elastomer is pressed in this
Accommodating cavity.
The utility model can reach following beneficial effect：By the way that the face of cylinder will be configured on the outside of attached raceway body, make attached
Category raceway body and outer ring the inner surface of the casing between forming face contact, increase its contact area, by by attached raceway body with roll
Contact level is configured to annular circular arc concave surface, increases the parcel face to rolling element, improves bearing stability, reduces bearing work
Caused noise in work, extends bearing service life.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes inner ring 1, retainer 6, rolling element 7 and outer ring assembly, the periphery of inner ring 1
Provided with outer raceway, the outer ring assembly includes outer ring case 5, elastomer 3 and two attached raceway bodies 4, two attached raceway bodies 4
Relative and put and be positioned in outer ring case 5, attached raceway body 4 be in annular, and each the attached radial outside of raceway body 4 is into cylinder
Face, it is set to be contacted between the inner surface of outer ring case 5 for face, the inner side of each attached raceway body 4 is equipped with annular circular arc
Concave surface, two annular circular arc concave surfaces are combined into is engaged raceway in corresponding with the outer raceway, and rolling element 7 passes through the holding
Frame 6 supports cooperation to be installed between the interior raceway and outer raceway, and the elastomer 3 is built in the outer ring case 5 and right
One of them attached raceway body 4 forms axial pressing；The both ends of the outer ring case 5 all set radially inner turn-up portion 2, right
Described attached raceway body 4 forms axial limiting, and the turn-up portion 2 of wherein one end is axially bent to form for housing the elastomer
3 accommodating cavity, the elastomer 3 are pressed in the accommodating cavity.
Claims (3)
