Definitions
- the present disclosure is directed to a bearing cage segment of a sheet metal cage having an improved joint edge for welding and to a sheet metal cage including such a bearing cage segment.
- Bearing cages are known from the prior art that are composed of one or more rounded cage segments, made of sheet metal, that are respectively connected to one another at their joint edges, for example by welding.
- a metal band is intermittently moved in the longitudinal direction, wherein transversely extending slots are formed by a punch press.
- the metal band is cut to length using a transverse cutting device so that a ladder-shaped sheet metal part is formed, wherein the “rungs” of this part form bridges of the bearing cage segment, the slots of the part form pockets of the bearing cage segment, and the “side rails” of the part form the ring sections of the bearing cage segment.
- the ring sections are then bent to a desired radius of curvature by round molds.
- the cutting-to-length is usually effected here in the region of a pocket so that a joint edge is formed on each of the ring sections and a “partial pocket” is formed therebetween.
- these joint edges after a post-processing, which is to be discussed in more detail below—are welded together with two further, analogously formed joint edges, so that a “welding pocket” is formed by the connecting of the “partial pockets.”
- Cutting-to-length is a punching process in which a combined shear-cutting and breaking occurs. For this reason the joint edges of the ring sections, which joint edges are formed by the cutting-to-length of the sheet metal and are directed in the circumferential direction, are not dimensionally stable enough to be able to serve directly as a welding surface. The post-processing mentioned here is therefore required. In addition, a cutting liquid is typically used during the cutting-to-length which must still be removed for a further processing.
- the post-processing here is necessarily associated with a material removal. If, therefore, after the bearing cage segment has been bent round the post-processed joint edges were to simply be welded to the corresponding joint edges opposing in the circumferential direction, then at this connecting point a welding pocket would be formed which, viewed in the circumferential direction, would have a smaller width than the other pockets. For this reason, according to the prior art, after cutting to size the ring sections are first shortened by approximately a complete pocket width and only then post-processed, so that with respect to the desired pocket width they have the correct length for connecting to the opposing joint edges. The final bridge is lost in this way as waste. Accordingly, in addition to the additional effort of the post-processing, significant material loss also occurs here.

- the bearing cage segment includes, on at least one ring section, a joint edge directed in the circumferential direction, which joint edge is configured to be connected to another joint edge, wherein the joint edge is disposed in the region of a pocket to be formed by this connection, and wherein the joint edge is formed by laser cutting.
- bearing cage segment can be configured for single-row or multi-row bearing cages.

- the bearing cage segment can be individually manufactured by laser cutting, for example, by a cutting-out from a metal sheet, so that the joint edge need not be formed by cutting to length. In this way the material loss, as occurs in the above-mentioned prior art, can also be avoided. The manufacturing is thus made easier.

However, the producing of the “normal” or “whole” pockets can advantageously be effected by a simple and rapid punching.
- the joint edge is disposed approximately centrally with respect to the to-be-formed pocket.
- a particularly symmetrical design arises, whereby it can be achieved that undesirable non-uniform forces that act on the connection during operation of the finished bearing cage can be avoided, or are at least particularly low.

Description
- This application claims priority to German patent application no. 10 2019 201 560.3 filed on Feb. 7, 2019, the contents of which are fully incorporated herein by reference.
- The present disclosure is directed to a bearing cage segment of a sheet metal cage having an improved joint edge for welding and to a sheet metal cage including such a bearing cage segment.
- Bearing cages are known from the prior art that are composed of one or more rounded cage segments, made of sheet metal, that are respectively connected to one another at their joint edges, for example by welding.
- Here it is known to produce the structure and contour of such bearing cage segments by punching and stamping. For this purpose in a first step a metal band is intermittently moved in the longitudinal direction, wherein transversely extending slots are formed by a punch press. In a further step the metal band is cut to length using a transverse cutting device so that a ladder-shaped sheet metal part is formed, wherein the “rungs” of this part form bridges of the bearing cage segment, the slots of the part form pockets of the bearing cage segment, and the “side rails” of the part form the ring sections of the bearing cage segment. In a subsequent step the ring sections are then bent to a desired radius of curvature by round molds.
- The cutting-to-length is usually effected here in the region of a pocket so that a joint edge is formed on each of the ring sections and a “partial pocket” is formed therebetween. When assembling the bearing cage segment into a finished cage, these joint edges—after a post-processing, which is to be discussed in more detail below—are welded together with two further, analogously formed joint edges, so that a “welding pocket” is formed by the connecting of the “partial pockets.”
- Cutting-to-length is a punching process in which a combined shear-cutting and breaking occurs. For this reason the joint edges of the ring sections, which joint edges are formed by the cutting-to-length of the sheet metal and are directed in the circumferential direction, are not dimensionally stable enough to be able to serve directly as a welding surface. The post-processing mentioned here is therefore required. In addition, a cutting liquid is typically used during the cutting-to-length which must still be removed for a further processing.
- The post-processing here is necessarily associated with a material removal. If, therefore, after the bearing cage segment has been bent round the post-processed joint edges were to simply be welded to the corresponding joint edges opposing in the circumferential direction, then at this connecting point a welding pocket would be formed which, viewed in the circumferential direction, would have a smaller width than the other pockets. For this reason, according to the prior art, after cutting to size the ring sections are first shortened by approximately a complete pocket width and only then post-processed, so that with respect to the desired pocket width they have the correct length for connecting to the opposing joint edges. The final bridge is lost in this way as waste. Accordingly, in addition to the additional effort of the post-processing, significant material loss also occurs here.
- The quality of the welded joint is of particular significance here since the performance of the finished bearing cage significantly depends thereon.
- It is therefore an aspect of the present disclosure to provide a bearing cage segment that can be manufactured with high reliability at lower expense.
- In the following a bearing cage segment of a sheet metal cage, in particular for a needle roller bearing, is provided, which includes a first ring section, at least one second ring section, and a plurality of bridges connecting the first ring section and the at least one second ring section to each other, wherein a pocket for receiving at least one rolling element is respectively formed between the bridges. Here the disclosure is based on the idea that the bearing cage segment includes, on at least one ring section, a joint edge directed in the circumferential direction, which joint edge is configured to be connected to another joint edge, wherein the joint edge is disposed in the region of a pocket to be formed by this connection, and wherein the joint edge is formed by laser cutting.
- Here the bearing cage segment can be configured for single-row or multi-row bearing cages.
- The joint edge can be formed so precisely by the laser cutting that it is directly suitable as a welding edge. In this way a post-processing of the welding edge is not required for a reliable welding connection. In addition, the bearing cage segment can be individually manufactured by laser cutting, for example, by a cutting-out from a metal sheet, so that the joint edge need not be formed by cutting to length. In this way the material loss, as occurs in the above-mentioned prior art, can also be avoided. The manufacturing is thus made easier.
- According to one exemplary embodiment, the joint edge includes a chamfer on the radially outer side and/or the radially inner side. This design makes it possible that during the production of the welding connection no region forms that projects radially or axially over the respective ring section, in particular no projecting weld seam (so-called upper bead).
- A particularly simple manufacture of the chamfer is made possible when it is formed by a reshaping process, i.e., for example, by a rolling or a milling.
- According to one exemplary embodiment the entire to-be-formed pocket is laser-cut, wherein the other pockets are preferably punched. Due to the laser cutting of the to-be-formed pocket, the joint edge can be correspondingly advantageously configured. However, the producing of the “normal” or “whole” pockets can advantageously be effected by a simple and rapid punching.
- According to one exemplary embodiment, the joint edge is disposed approximately centrally with respect to the to-be-formed pocket. In this way—with respect to a plane of the welding connection—a particularly symmetrical design arises, whereby it can be achieved that undesirable non-uniform forces that act on the connection during operation of the finished bearing cage can be avoided, or are at least particularly low.
- According to one exemplary embodiment, the ring sections include a joint edge in the region of the to-be-formed pocket. The above-mentioned advantages thus arise in all ring sections.
- According to a further aspect of the disclosure a sheet metal cage is provided, in particular for a needle roller bearing, that includes at least one of the above-described bearing cage segments. Here the at least one bearing cage segment or the plurality of bearing cage segments are connected at their joint edges via a material-bonded connection, in particular welded. The sheet metal cage can thus be manufactured particularly advantageously overall. Electrical resistance welding or laser welding are particularly suitable here as welding. It can thus be achieved that the weld seam is particularly small. The sheet metal cage can be configured single-row or multi-row.
- Further advantages and advantageous embodiments are provided in the description, the drawings, and the claims. Here in particular the combinations of features specified in the description and in the drawings are purely exemplary, so that the features can also be present individually or combined in other ways.
- In the following the invention shall be described in more detail using exemplary embodiments depicted in the drawings. Here the exemplary embodiments and the combinations shown in the exemplary embodiments are purely exemplary and are not intended to define the scope of the invention. This scope is defined solely by the pending claims.

FIG. 1 is a perspective representation of a connecting region of a bearing cage segment according to an embodiment of the disclosure. -
FIG. 2 is a cross-sectional representation of two mutually contacting joint-edge regions of a bearing cage segment before being welded. -
FIG. 3 is the bearing cage region ofFIG. 2 after being welded. - In the following, identical or functionally equivalent elements are designated by the same reference numbers. The direction designations used in the following—axial, radial, circumferential—always refer to the finished bearing cage.
-
FIG. 1 shows an exemplary embodiment of at least one inventivebearing cage segment 1 of a sheet metal cage in the joint region between a first bearing cage segment end 6 and a second bearingcage segment end 9. Here the sheet metal cage is can be formed from a single bearingcage segment 1, so that the bearing cage-segment ends 6, 9, also referred to here in the following simply as “ends” 6, 9, are two circumferential ends of only one bearingcage segment 1. Alternatively the sheet metal cage can include a plurality of bearing cage segments, wherein the first end 6 is one end of a first bearingcage segment 1, and thesecond end 9 is one end of a second bearingcage segment 1. - For the sake of simplicity it is assumed in the following that two bearing
cage segments ends 6, 9. The case that the first end 6 and thesecond end 9 are formed by the samebearing cage segment 1 obviously arises in an analogous manner. - Each bearing
cage segment first ring section 2 and asecond ring section 3, and a plurality ofbridges 4 connecting thefirst ring section 2 and thesecond ring section 3 to each other. InFIG. 1 only thefinal bridge 4 of the first end 6 and thefinal bridge 4 of thesecond end 9 are shown. Instead of the single-row design of the bearingcage segment 1 depicted here, the bearingcage segment 1 can also be configured multi-row, and would then include a first, a second, and further ring sections that are each connected to each other by bridges. - A
pocket 5 for receiving at least one rolling element is respectively formed between thebridges 4. In the example shown the sheet metal cage is a needle-roller-bearing cage, and thepockets 5 are each configured for receiving a needle-shaped rolling element. - On its first end 6 on the

Accordingly a first “partial pocket” is formed by the first end 6, and a corresponding second partial pocket by thesecond end 9, wherein due to the connection of thejoint edges be-formed pocket 14 or are assembled into the to-be-formed pocket 14. - Here, viewed in the circumferential direction, the
joint edges welding pocket 14. In particular the design can be such that thejoint edges be-formed pocket 14. However, thejoint edges - The
joint edges bearing cage segment 1, or of thesecond end 9 of the secondbearing cage segment 1′, is preferably formed by laser cutting. In this way thejoint edges - On the
second ring section 3 the design in the region of the connection is preferably analogous to the design on thefirst ring section 1. - The pockets 5 (without the “welding pocket” 14) can all be formed by punching.
- As can be seen from
FIG. 1 , guide surfaces 15 of thepockets 5 for guiding the rolling elements can be formed on thebridges 4 and on thering sections pockets 5. Thewelding pocket 14 can also include corresponding guide surfaces 15 that can preferably be directly formed here by the above-mentioned laser cutting of the respective partial pockets. -
FIG. 2 shows a cross-sectional representation through thefirst ring section 2 in the region of the connection of thejoint edges joint edges - As can be seen from
FIG. 2 , thejoint edges first chamfer 10 on the radially outer side, and asecond chamfer 11 on the radially inner side. Thechamfers FIG. 3 the state is shown after the welding. Theweld seam 12 formed by the welding can be seen here. Due to thechamfers - The
chamfers cage segment 1 need not be transported to a further tool to form thechamfers - In summary a bearing cage segment is provided that includes a laser-cut joint edge that is directly suitable for a weld connection. Here the joint edge includes a chamfer, whereby the formation of a projection is avoided in the course of the welding.
