Description

Cylindrical roller bearings, especially needle roller bearings

The innovation concerns a cylindrical roller bearing, in particular needle roller bearings, the outer ring of which consists of a sleeve with one or both ends alternately inward and outward bent flaps consists of »

In various cases, especially when using needle bearings it is often necessary that the bearing outer ring in axial Sighting fixed in the housing, d. h, is fixed. A well-known execution has for this purpose an outer bearing ring made of sheet metal, a so-called sleeve, which at one end faces inwards and at the other Front end is provided with an outwardly flanged border. However, this design has the disadvantage that at the end of the outer ring, at which the board is directed outwards, Ice an approach possibility for the Needles or for the needle cage is available. The needles or the needle cage can easily fall out or "run out" here.

To remedy this disadvantage it has already been suggested for the start-up the needles or the needle cage on the side on which the board faces outwards is bent to attach a disk closing the open end of the sheet metal sleeve. In one of these known solutions it is proposed to glue, rivet, o can be snapped over the outward-facing shelf.

In these two versions there is a bearing sleeve in addition to the actual bearing sleeve special washer attached to the bearing sleeve for axial guidance or mounting of the bulwark or the cage is necessary, their assembly after all, is associated with some difficulties. To get around these difficulties and to create a far cheaper solution without one such a special start-up bsxir. Cover disk, is made according to the present Proposed innovation, one or both ends of the thin-walled bearing ring to be provided with lugs for cylindrical roller or needle roller bearings,

which are crimped alternately inwards and outwards after inserting the oar body or the set with cage in the outer ring and the outer ring in the housing. The inwardly beaded tabs serve directly or indirectly as axial contact surfaces for the roller bodies or for the cage, the outwardly beaded tabs ensure the axial fixation of the bearing outer ring The tabs can be easily attached to your thin-walled bearing outer ring, e.g. through axial cuts at the ends of the tubular body. It is not to be noted in particular that the bearing outer ring is expediently hardened only in the area of the raceway of the roller bodies, while the ends provided with the tabs remain soft for better deformation.

The innovation should be based on the exemplary embodiments shown in the drawing are explained in more detail. Is show:

Fig. 1 a needle bearing with cage and bearing outer ring according to the innovation

Fig. 2 shows another embodiment of a needle bearing according to the innovation with between the cage and the inwardly bent lobes arranged discs

Fig. 3 ^e i ⁿ needle bearing without a cage in accordance with the innovation

Fig. 4 shows another embodiment of a needle roller bearing without a cage according to the innovation

In the embodiment according to Fig. 1, the needle bearing consists of the thin-walled one Outer ring 1, the needle cage 2 and the needles 3> which are directly on the ΐ / elle 4 run. The outer ring 1 has a tab 7 at both ends 5 and 6 and 8, which are alternately bent inwards or outwards »The inwards bent tabs 7 take over the axial guidance of the Needle cage 2, the outwardly directed tabs 8 are on the side surfaces 9 of the housing 10 and thus fix the outer ring of the bearing in the housing,

In general, no difficulties arise when the cage side surfaces on the interrupted surface of the nacli inwardly bent lobes start up, but in certain cases it is advisable to attach the cage to a to let the closed area start to run. This can be done in the simplest of ways can be achieved in that between the cage side rings and after inside flanged flaps each one King disc is provided.

Such a solution is shown in Fig. 2. The bearing outer ring is formed here exactly as in Fig. 1. Between the cage side ring 11 and the inwardly directed tab 7 is merely an annular disk 12 loosely inserted. The cage runs here on the annular disks 12, which are fixed in axial sighting by the tabs 7,

This version is also applicable to a needle bearing, as it is, for example, in Fig. 3 is reproduced, applicable. The bearing outer ring is here too, like already described above, trained. The needles 3 are here, however not guided axially parallel by a cage and in radial sighting held inside. Rather, the needles are right next to each other and are guided in axial direction through the inserted iling disks 12. These are in turn, as already mentioned above, by the tabs 7 in axial alignment set.

To prevent the needles from falling out inwards, it is like in Fig. 4 expediently shown, the inserted single disks 12 on their inner diameters 13 with lugs directed against one another in the axial direction 14 to strand the tips 15 of the closely adjacent Include needles.

The embodiments described here represent only a few examples the innovation. ils can easily be changed and expanded which should not be mentioned here any further. The idea of hiring is not limited to needle bearings, but can be used in the same way Way with all bearings with cylindrical hollow bodies and thin-walled Find outer rings use.
