Axial needle roller bearings

The innovation relates to an axial needle roller bearing with a planar radial one Flange of the housing and a thrust washer located between the needle roller and radial flange.

A combined axial-radial bearing with needles or rollers is known as a rolling element and a sleeve that has a radial collar for the Has thrust bearings. A flat roller disk rests on this collar and can make small angular movements around this collar in both directions to adjust the bearing. The disadvantage here is that the bushing is of complicated design, and that forces can act on the bushing during installation, which deform the bushing so that the exact axial dimensions of the bearing are no longer complied with.

The task of the innovation is to create an axial needle bearing with an angularly adjustable thrust washer.

This object is achieved according to the invention in that the thrust washer on the side opposite the radial flange of the housing b Cross-section is designed convex. It is known, the thrust washer to be provided with a convex raceway; However, this only avoids edge pressure on the needles in the event of uneven loading, an adjustability of the thrust washer is not achieved. With the object the innovation, however, the needles are fully on a flat side of the stop disk. The adjustability of the bearing becomes more straightforward Way between the thrust washer and the radial flange of the housing is created.

In an advantageous embodiment of the innovation, the thrust washer a flat area and at least one projection in cross section. Such a disk can be manufactured in a particularly cost-saving manner and also offers the advantages described above for the warehouse.

Further advantages, features and application possibilities of the innovation according to the invention Axial needle roller bearings result from the figures and the following Description of these figures.

It shows:

Fig. 1 shows an axial section through a combined axial-radial bearing according to the innovation and

2 shows an axial section through an axial needle roller bearing with thrust washer.

Figure 1 shows a combined axial radial bearing 1 with a radial bearing and a thrust bearing 3 · The radial bearing 2 has an outer ring 4, a Inner ring 5, needles 6 and a cage 7. A radial flange 8 for the axial bearing 2, which is provided with an edge 9, is integral with the outer ring is. The axial bearing J5 also has a thrust washer 10, a wave washer 11, needles 12 and a cage IJ. The thrust washer 10 has in Area of the radial flange 8 and, opposite this, a projection 14, which extends from the flat area 15 of the side 16 of the thrust washer 10 extends out. By means of the projection 14, the thrust washer Adjust angular movement. The projection 14 extends over the entire The circumference of the stop disk and thus forms an annular region. With special In certain applications, the projection can also be provided only in part of the circumference of the stop disk.

Figure 2 shows an axial sonicity through an axial needle roller bearing, the same Reference numerals as in Figure 1 were used. The side 16 of the thrust washer 10 is designed crowned here. The side 17 of the stop disk 10, which is in contact with the needles 12, is shown in FIGS just designed.
