Background technique
As everyone knows, retainer is one of vitals of rolling bearing, and its effect is that the guiding rolling element runs well in bearing working, at any time keeps rolling element not break away from bearing.In addition, in order to obtain operating condition or installation conditions preferably, retainer generally also need be controlled the free movement of the relative retainer of rolling element, can not limit narrowly so that can not freely rotate rolling element, can not cross pine so that assembling or difficult installation.Usually; Retainer is to keep rolling element not break away from through constraint rolling element outer surface, and said outer surface is the ball surface to the ball bearing speech, is outer round surface to the roller bearing speech; All be the load-bearing surface or the working surface of rolling element in a word; When effect of contraction takes place, inevitably working surface is exerted an influence like this, like lubricant flow to, wearing and tearing difference etc., thereby influence the performance and the working life of bearing.
In order to control the free movement of rolling element, the retainer of above-mentioned hold mode has quite high requirement to precision in design and manufacturing, and cost is higher.Different with ball bearing, for roller bearing, comprise roller bearing, tapered roller bearing, spheric roller bearing, can produce additional geometric element in the roller end, like depression, hole etc., should keep roller in additional geometric element surface through constraint.At present, keep the retainer of roller that punching roller retainer, punching press protrusion lock point retainer are arranged through the additional geometric element surface of constraint roller.Punching roller retainer need bore a through hole on roller; Influence roller intensity; And because the on-stream effect that receives power all the time of roller axle, in case get loose the generation serious consequence, so higher to design, manufacturing and the matching requirements of retainer; Can only use at extra large size bearing, only be applicable to single-piece or small lot production.Punching press protrusion lock point retainer such as European patent EP 0225975A2 propose a kind of steel plate punching press retainer and still are used for the middle-size and small-size E type of SKF main product selfaligning roller bearing at present; The lock point of this retainer is once processed with retainer; Only rely on resiliently deformable to pack into and pin roller; Therefore very high to required precision, limited by stamping process, this retainer is not suitable for large-scale or extra large size bearing.
The model utility content
The purpose of the utility model is to provide a kind of roller bearing retainer; This retainer structurally provides condition for the lock point that stamps out the constraint roller in the follow-up bearing assembling; This way of restraint does not only disturb, influences the normal operation of bearing fully, and simple in structure, and required precision is lower; Can also control the free movement of the relative retainer of roller as required; Make easy to assemblyly, can effectively solve the shortcoming that roller bearing retainer in the existing technology exists, adapt to various lots of production, all kinds of roller bearings of the above extensively dimensional range of external diameter 120mm use.
The purpose of the utility model is to realize through following technological scheme:
A kind of roller bearing retainer; It is made up of two side rings and several lintels of being connected between two side rings; The side of the inner side surface of said two side rings and adjacent two lintels constitutes the fenestra that roller is installed; Wherein, have at least the outside of each fenestra position of a side ring to offer blind hole in said two side rings, thin-walled is left in said blind hole bottom.
Especially, the thickness of thin-walled is 0.8～2mm bottom the said blind hole.
Especially, said fenestra is that a cross section is the simple straight hole of rectangle.
The beneficial effect of the utility model is that said roller bearing retainer can pass through from blind hole hole diapire punching press after roller is packed the retainer fenestra into; Form protruding lock point; This lock point is projected into and pins roller in the depression that is shaped in advance on the roller end face, and roller can not be come off from the retainer fenestra, has simplified fenestration simultaneously; Make fenestra bring into play the function that guide rolls runs well purely, avoid producing the negative effect of disturbing running; Not only the roller hold mode reliability of retainer is high, and lock point place can not produce friction when the bearing proper functioning; And retainer is simple in structure, and required precision is lower, makes easy to assemblyly, adapts to all kinds of roller bearings of the above extensively dimensional range of various lots of production, external diameter 120mm and uses.In addition, this retainer can also be controlled the free movement of the relative retainer of roller effectively.
