Sign is that width to the width of inner side that described bar shaped retaining hole is located at the external side of retainer tapers into, and bar shaped is kept
Hole both sides have the arc-shaped recliner face for tilting and being oppositely arranged respectively, are respectively equipped with outside described bar shaped retaining hole both sides spacing
Bar, described positive stop strip is curved, and a positive stop strip in two positive stop strips on the outside of each bar shaped retaining hole is with protecting
Hold support body by the way that connected structure is removable to be connected, another positive stop strip is with keeping support body to be fixedly linked；Or each bar shaped is protected
Two on the outside of hole positive stop strips are held by connected structure with keeping that support body is removable is connected.During assembling, when two positive stop strips are equal
During installation removable with holding support body, first any one positive stop strip and retainer body phase are connected, roller is then positioned over bar shaped
In retaining hole, and on the outside of roller uniform arcuate shape inclined plane against a remaining positive stop strip finally is close into roller and circumferentially rotated
Roller is until complete the installation of a remaining positive stop strip.
In above-mentioned single-row roller bearing retainer, described connected structure includes being arranged on the positioning of positive stop strip end
Post, described keeps the upper jack that setting corresponding with locating dowel is provided with bar shaped retaining hole side of support body, described positioning
Post inserts in jack and described jack is obliquely installed towards bar shaped retaining hole side.
In above-mentioned single-row roller bearing retainer, described locating dowel cross section is in have short parallel edges parallel with length
The isosceles trapezoid on side, and the length of the short parallel edges of described locating dowel, the length of long parallel edges and short parallel edges are put down to long
The ratio between three on row side is：1：2-3：1.5-2.
In above-mentioned single-row roller bearing retainer, there is arc retaining surface on the inside of described positive stop strip, and it is described
There is the bar shaped oil groove of some arcuately retaining surface widths extension in arc retaining surface.Reduce the mill of retaining surface and roller
Damage.
In above-mentioned single-row roller bearing retainer, the quantity of described bar shaped oil groove for 3 and arcuately retaining surface
Length direction be uniformly distributed setting.
In above-mentioned single-row roller bearing retainer, described arc retaining surface belongs to same with arc-shaped recliner face
Circular different curved portions.
In above-mentioned single-row roller bearing retainer, the width of the one end of described positive stop strip with retainer body phase even is extremely
The width of the other end tapers into.
In above-mentioned single-row roller bearing retainer, described holding support body both ends outer circumferential flips over to be formed
Annular retaining ring.
Compared with prior art, it is the advantages of this single-row roller bearing retainer：Simple in construction, stability is good, just
In the installation of roller, lubricity is high, not easy to wear between rolling body and retainer, service life length.

Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As Figure 1-3, this single-row roller bearing retainer, including cylindrical holding support body 1, keep support body 1 week
To with some, along the axially extending bar shaped retaining hole 11 of support body 1 is kept, bar shaped retaining hole 11 is positioned at the width for keeping the outside of support body 1
The width spent to inner side tapers into, and the both sides of bar shaped retaining hole 11 have the arc-shaped recliner face for tilting and being oppositely arranged respectively
111, positive stop strip 12 is respectively equipped with outside the both sides of bar shaped retaining hole 11, and positive stop strip 12 is curved, and each bar shaped retaining hole
A positive stop strip 12 in two positive stop strips 12 in 11 outsides is connected with holding support body 1 by the way that connected structure 2 is removable, another
Positive stop strip 12 is with keeping support body 1 to be fixedly linked；Or two positive stop strips 12 in each outside of bar shaped retaining hole 11 are by inserting
Binding structure 2 is with keeping that support body 1 is removable is connected, during assembling, when two positive stop strips 12 are with holding 1 removable installation of support body,
First any one positive stop strip 12 is connected with holding support body 1, then roller is positioned in bar shaped retaining hole 11, and on the outside of roller
Uniform arcuate shape inclined plane 111 is against being finally close to roller by a remaining positive stop strip 12 and circumferentially rotate roller until completing surplus
Remaining the installation of a positive stop strip 12.
Specifically, the connected structure 2 in the present embodiment includes being arranged on the locating dowel 21 of the end of positive stop strip 12, keeps support body
The jack 22 with 21 corresponding setting of locating dowel is provided with positioned at the side of bar shaped retaining hole 11 on 1, locating dowel 21 is inserted in jack 22
And jack 22 is obliquely installed towards the side of bar shaped retaining hole 11.The cross section of locating dowel 21 in the present embodiment is in have short parallel edges
221 with the isosceles trapezoid of long parallel edges 222, and the length of the short parallel edges 221 of described locating dowel 21, long parallel edges 222
The ratio between three of length and short parallel edges 221 to long parallel edges 222 is：1：2-3：1.5-2.In order to reduce arc
Shape inclined plane 111 and the abrasion of roller, the inner side of positive stop strip 12 have arc retaining surface 121, and if having in arc retaining surface 121
The bar shaped oil groove 122 of the dry arcuately width of retaining surface 121 extension.
Further, the quantity of bar shaped oil groove 122 here is 3 and the length direction of arcuately retaining surface 121 is uniform
Distribution is set.Here arc retaining surface 121 belongs to same circular different curved portions from arc-shaped recliner face 111.This reality
The width for applying the width to the other end of one end that the positive stop strip 12 in example is connected with holding support body 1 tapers into.Here holding
The both ends outer circumferential of support body 1 flips over to form annular retaining ring 13.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
Although holding support body 1, bar shaped retaining hole 11, arc-shaped recliner face 111, positive stop strip 12, arc have more been used herein
Shape retaining surface 121, bar shaped oil groove 122, annular retaining ring 13, connected structure 2, locating dowel 21, jack 22, short parallel edges 221, length are flat
The grade term of row side 222, but it is not precluded from the possibility using other terms.It is used for the purpose of more easily retouching using these terms
State and explain the essence of the present invention；Any additional limitation is construed as all to disagree with spirit of the present invention.
