Rolling bearings with cage segments made from thin-walled sheet metal

The invention relates to a roller bearing with cage segments made from thin-walled sheet metal, in particular half-shells _P, the end ring sections of which are connected to one another by webs.

Segment cages for roller bearings are used in particular when one-piece cylindrical cages are not can be installed because they are, for example, in a recess or between two fixed guide ribs a Shaft must be arranged. So-called half-shell cages are usually used for such installation cases, which consist of two loose cage halves. Such half-shell cages are solid or relatively thick-walled material known. If you make such segment cages from thin-walled sheet metal, so there is the risk that the individual segments due to the small cross-sectional areas at the joints impose on each other. This can lead to the destruction of the bearing.

The invention is based on the object of eliminating this disadvantage and producing it from thin-walled sheet metal To create cage segments that have a larger cross-sectional area at the joints than this of the simple Sheet metal wall thickness. According to the invention, it is proposed for this purpose that the cross-sectional areas of the Stirnrlngabschnitttt the cage segments by folding over the cage *

Material are enlarged. This means that there is no longer any risk that the individual cage segments or sieve Hook the half-shells together.

According to an advantageous embodiment of the invention, this results in a further enlargement of the abutment surfaces achieves that the cage material folded over at the end ring sections extends into the end sections of the webs extends.

An embodiment of the invention is shown in the drawings and will be described in more detail la following. Show it

1 shows a view of a roller bearing according to the invention with a cage consisting of two half-shells, partially in section, the lower half-shell being equipped with rolling elements,

FIG. 2 is a side view of FIG. 1,

3 shows a half-shell with end ring sections folded over into the end area of the webs in a partial view and in a partial cut.

The needle bearing shown as an embodiment in Figures 1 and 2 consists of the two cage half-shells 1 and 2 with windows 3 for the needles 4. The windows are delimited by profiled webs 5, the web sections arranged to hold the rolling element on both sides of the needle pitch circle 6 7 and 8, the distance between which is smaller than the rolling element diameter. The end rings 9 are through Folding over of the cage material is reinforced in order to obtain a larger cross-sectional area. At the junction of the Kifighhalschaltn 1Q bevels are provided that tin Butt against adjacent components, e.g. thrust washers, impede.

FIG. 3 shows a half-shell 11 in which the cage material is folded over as ^{far as the end sections Λ} 2. This increases the joint surfaces again *
