A visible rolling bearing retainer 1 in Fig. 1, local in decomposition view, this rolling bearing retainer is by as constituting at the parts as shown in Fig. 2 and Fig. 3.

Retainer 1 has a plurality of bridge members 4, and this bridge member is connected with 3 with side circle 2 with two axial end portion.At this,

side circle

2,3 is by a plurality of interconnective side circle segmentation 2 ', 2 ", 2 " ' or 3 ', 3 ", 3 " ' form.The retainer groove 5 that is used for holding rolling element (not shown at Fig. 1) is between bridge member 4, by side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' axially limit.Interconnective side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' become the loop configuration of combination at circumferential U-shaped.

In scheme, be designed to by Fig. 1 to 3, that is, side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' be connected with bridge member 4 by means of the connection 6 of form fit.How the structure of the connection of this form fit is drawn by Fig. 2 and 3.Side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' have hook-shaped projection 6 ' in its end, and specifically be as shown in Figure 2, have each two hook-shaped projection 6 ', one of them is from top radially outstanding, and one from following radially outstanding.As shown in Figure 3, bridge member 4 respectively has a form at the end regions of radial outside and radially inner side and is the recess 6 at axially extended groove ".Hook-shaped projection 6 ' and groove 6 " be to be provided with like this, make side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' forked end portions can kayser at groove 6 ', so that keep regularly.At this, groove 6 " be designed to widely like this, make that two hook-shaped projectioies 6 ' are at groove 6 " in installation position is arranged, that is to say, if the segmentation of side circle is fixed on groove 6 " in, two adjacent side circle segmentations 2 ', 2 ", 2 " '; 3 ', 3 ", 3 " ' the end lean mutually at circumferential U.This is shown in Figure 1.Because at circumferential U is that hook-shaped projection 6 ' forms groove 6 " the undercutting undercut, guaranteed fixedly connected along circumferential U, especially when hook-shaped projection 6 ' and recess 6 " the formation kayser is connected or when clamping connection.

Show similar scheme at Fig. 4.Side circle segmentation 2 ', 2 as used herein ", 2 " ', 3 ', 3 ", 3 " ' (see figure 5) and bridge member (see figure 6) be connected 6 by form fit equally " ' connect.At this, this connection is by the projection 6 that thickens at end regions " ' form, this projection can rabbet have conform to, the recess 6 of corresponding adaptive shape just " " in.This connects also press kayser or to clamp the type structure that connects, that is when projection 6 " ' be pressed into recess 6 with enough pressing forces " " in the time, this protrusions snap is at recess 6 " " in, and so maintenance regularly.

By Fig. 4 also as can be known, be provided with a rolling element director element 8 at bridge member 4 towards that side of receiving groove 5.This director element is used for improving the guiding of rolling element at groove 5.

Fig. 7 shows the another kind of optionally design of the present invention.At this, in side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' end regions each the design have one the ring or enclose 6 " " ', it forms hole 9, sees that vertically this hole is corresponding to the shape of cross section of bridge member 4.Correspondingly, side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' can move with this bridge member towards bridge member 4 by a vertically and be connected.At this, the size in hole 9 can be chosen as the cross section that is slightly less than bridge member 4, makes to push, and just can be used for side circle segmentation 2 ', 2 then ", 2 " ', 3 ', 3 ", 3 " ' fixedly maintenance on bridge member 4.

Fig. 8 shows different with Fig. 7, but very similar scheme.The common ground of two kinds of forms of implementation is, in assembling condition downside circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' have in axially complementary shape, that is to say, it makes side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' assembling, by each single side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' obtained the circular contour of essentially no interruption.Correspondingly, obtained almost do not have the end face 7 (seeing Fig. 7 and Fig. 8) that interrupts.Be noted that the design by Fig. 8 is easier to assembling,, the side circle segmentation 2 ', 2 that lacks because in the end ", 2 " ', 3 ', 3 ", 3 " ' can axially push easily, and in pressing the scheme of Fig. 7, latter two part must be assembled across.

Fig. 9 to 16 has provided other possible form of implementation of the present invention.

By Fig. 9 to 12 as seen, in this side circle segmentation 2 ', 2 "; 2 " ', 3 ', 3 "; 3 " ' be designed to arc a little, and be formed with hook-shaped projection respectively at its end regions, this projection had both been rabbeted in adjacent side circle segmentation 2 '; 2 ", 2 " ', 3 '; 3 "; 3 " ' in, also to rabbet in bridge member 4, they have respectively that the recess of corresponding unanimity is used for described hooked projection.

In scheme, (figure 16 illustrates the view of seeing vertically by the retainer of Figure 14), adjacent side circle segmentation 2 ', 2 by Figure 13 and Figure 14 ", 2 " ', 3 ', 3 ", 3 " ' rabbet mutually by the connection 6 of form fit.At this, bridge member 4 can be by side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' inlay and therefore be fixed.At this, the connection of form fit is designed to the projection 6 that thickens again " ', this projection interlocking is at corresponding recess 6 " " in.Two bridge members 4 also are set between two receiving grooves 5 in Figure 13 and Figure 14, and it is used to connect

side circle

2,3.

In pressing the scheme of Figure 13, also can be designed as in case of necessity, that is, bridge member 4 is connected and fixed by material, promptly for example by bonding.Shape connects 6 connections that guaranteed between the segmentation of side circle.

Figure 15 shows the another kind of scheme that substitutes.

Single parts for retainer 1 can use a large amount of prefabricated parts.Especially preferred is that wherein, bridge member 4 needed length intercept from continuous section bar for bridge member 4 uses the extrudate of for example making by extruding.The corresponding thus cost cheapness that retainer is made.

Figure 17 to 20 and 21 to 24 shows two other modification of the retainer of being advised, and Figure 17 and Figure 21 show retainer 1 respectively, and the details that retainer has been shown in Figure 18 to 20 or 22 to 24 of remainder.

At this, bridge member 4 is fabricated to sheet material, and wherein, lath is crooked in this wise, obtains two the same arms 4 ' and 4 ", they are a extension vertically respectively.

Side circle

2 and 3 single side coil element 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' being respectively equipped with a bending 15 (seeing Figure 19 and 23), it produces axial offsetting x.If single side circle segmentation is made up mutually, will obtain almost not having the loop configuration of interruption so.

In pressing the scheme of Figure 17 to 20, each bridge member 4 respectively has one in two axial end region and runs through portion's section 11.During this period, side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' having recess at two end regions (seeing) along circumferential U, this recess for example can be by the stamping process manufacturing.When retainer 1 assembling, per two side circles segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' axially be pushed on the bridge member 4 with its recess 10, and particularly run through on the part 11 at it, therefore obtained position as shown in figure 20.

A is provided with a supporting surface 12 (seeing Figure 18) on bridge member 4 vertically for this reason, makes side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' only can move to the axial position of determining on the bridge member 4.Run through part 11 and design so longways, make it when arriving assembling condition, axially slightly stretch out the segmentation of uppermost side circle.Fixing for setting up, non-removable connection runs through part 11 and has two retainer sections 14 in its axial end region, and the retainer section is concordant at axial a with the bridge member profile when assembling.As shown in figure 20, if side circle segmentation 2 ', 2 ", 2 " ', 3 ', 3 ", 3 " ' assembling during this period, then make 14 distortion of retainer section.Obtained that bridge member cooperates with side circle segmented shape thus and be fixedly coupled.

Be very similar to scheme ground structure by the retainer 1 of Figure 21 to 24 by Figure 17 to 20.

At this, axially mounting face 12 ', 12 " by bridge member 4 or its arm 4 ', 4 " free axial end portion form.Structure with the scheme of pressing Figure 17 to 20 is identical in addition.

Retainer by Figure 17 to 24 is preferably made by plate, and wherein, needed parts are by stamping process or deformation process manufacturing.When the form of implementation of the roller bearing shown in Figure 17 to 24 can be at parts phase strain type, be designed to tapered roller bearing.In addition, form fit can be not only passed through in being connected of bridge member and the segmentation of side circle, and guarantees by the material combination additionally, for example by laser bonding, and soldering, bonding.

Be that by the advantage of the such scheme of Figure 17 to 24 the traditional manufacturing of relative retainer saved material.In addition, this scheme provides bridging element shape structure variable possibility.At last, this form of implementation also provides such possibility, that is, assembling and dismounting can advantageously for example be carried out in the wind power station in site of deployment.

Another organization plan and the special expansion design of rolling bearing have been shown in Figure 25 to 28.At this, each bridge member 4 is made up of an integral member unlike aforesaid, but is made up of two bridging

elements

16 and 17 respectively.

In the form of implementation of pressing Figure 25 and 26, first bridging element 16 is made by the solid hopkinson bar with definite sectional shape, and first bridging element 16 preferably is made of metal.First bridging element 16 connects by two axial end portion and

side circle

2,3 or side coil element.As especially as shown in Figure 26, before the axial end portion of first bridging element 16 and

side circle

2,3 or side coil element are fixing, second bridging element 17 on pushing sleeve on first bridging element 16.For this reason, second bridging element 17 has groove 18, and its sectional shape is corresponding to the sectional shape of first bridging element 16.

Second bridging element 17 axial length of a vertically is equivalent to be used for the axial length of hope of the receiving groove of rolling element 23.

Correspondingly be designed to, bridge member 4 is made up of first bridging element 16 and second bridging element 17, and wherein, second bridging element 17 is connected with first bridging element, 16 form fit ground.

The connection of this form fit also can realize in the mode shown in Figure 27 and 28.After this, a kayser is set and connects 19, two bridging

elements

16 and 17 with being connected mutual form fit by the connection of this kayser.Kayser connects 19 and has two

hook parts

20 and 21 that are molded on second bridging portion 17, this second bridging portion side direction kayser or be clamped on first bridging element 16.Correspondingly, second bridging element 17 moves towards first bridging element 16 along the direction of arrow in Figure 28, wherein, connects 19 connections of setting up two form fit between the bridging

element

16,17 by kayser.

If also moulding or settle one or two kayser lip 22 on second bridging element 17, this kayser lip applies the maintenance effect to rolling element 23, can improve the maintenance for institute's assembling rolling element 23.

As further in Figure 28 as seen, rolling element 23 has than the bigger slightly diameter (record value is 34mm) of clear width (record value is 33.8mm) between two bridge members 4 or two bridging elements 17.Therefore, can when rolling element 23 assemblings, realize rolling element 23 snapping in receiving groove 5 by the elastic dilatation of bridge member 4.

Mention as top, the connection of (extra) material combination can be set between first bridging element 16 and

side circle

2,3, for example by welding.
