Axial plain bearings for shafts

The invention "relates to an axial plain bearing for ¥ ellen with tilting segments that can be installed and removed on both sides of a rotating thrust washer in the bearing housing, whose side facing the shaft is about has a flat outer surface.

Such known trapezoidal tilting segments are on all sides machined and have on one outside on the bearing housing and on its opposite outside Surface contact on the shaft side, line contact on the tilting edge and point contact on the side. The point contact is made by a spherical projection achieved. The production of these tilting segments is very complex.

There are also tilting segments arranged in cages, but again an additional effort for the cages is required.

The disadvantage of the known tilting segments is the self-adjustment of the wedge angle in the friction inhibition at the contact surfaces, especially when starting up under full load. By arranging spherical tipping points, tipping edges and convex tilting strips admittedly the disadvantage of the inhibition of the. Tilt segments decreased, but therefor is the technical effort is very great.

The object of the invention is to avoid the known deficiencies and to be easy to use. processing tilting segment to create that has point contact on all sides, whereby neighboring tilting segments are supported against each other in a point-like manner.

This object is achieved in that, in the case of an axial sliding bearing, each tilting segment is circular Has disk, on the one hand between a ring recess of the shaft enveloping and in the bearing housing used support ring and on the other hand a concentric to the ring turning existing, circular Track of the bearing housing is guided, and the circular discs of two adjacent tilting segments each Touch point-like, the support ring next to the ring recess an annular surface as a stop for the plane Has the outer surface of the tilting segments for the purpose of preventing the tilting segments from twisting.

The circular disc protrudes from the tilting segment at its point-like contact points. Through the all-round point contact, the freedom of movement of the tilting segment is relatively large, and the friction at the points of contact is reduced to a minimum. The tilting segments can easily adapt to the pressure disc.

In the drawing, the subject of the invention is in one Embodiment illustrated. It shows

Fig. 1 is a longitudinal section through a. Half of an axial plain bearing,

Fig. 2 is a section along line II-II

of Fig. 1 and '_

FIG. 3 shows an individual illustration A from FIG. 1.

The shaft 1 carries a thrust washer 2, which has tilting segments 3 is supported against the bearing housing 4. The tilting segments 3 have a well-known trapezoidal shape Education. They can also have a different shape, with the side 5 facing the shaft being approximately must have a flat outer surface.

Each tilting segment 3 has a circular disk 6 on that between a ring recess 7 of a die. Shaft 1 enveloping support ring 8 and one concentric to the ring recess 7 existing circular path 9 of the bearing housing 4 is guided. The support ring 8 is firmly inserted in the bearing housing 4. The circular disks 6 of two adjacent tilting segments touch each other at 10.

In addition to the annular recess 7, the support ring 8 has an annular surface 11 as a stop for the flat outer surface 5 of the tilting segments 3- This outer surface prevents the tilting segments from twisting around themselves Tilting segment 3 tries to rotate, one end of the flat outer surface 5 comes against the annular surface 11.

In a known manner, a 12 is on the bearing housing cover Stopper 13 is provided to prevent the entire set of tilting segments 3 from rotating with shaft 1 prevent.
