Abstract

An axial sliding bearing has a sliding ring disposed between two planar, ring-shaped sliding surfaces pressure-stressed against one another. The axial sliding bearing is overload-proof, in particular by about 30% to 80% with regard to the average pressure stress of about 30 to 40 bar per wedge segment that is usual in the case of wedge segment bearings, and at the same time, is not susceptible to axial vibrations, and, in this connection, can be easily produced in terms of production technology, and easily installed, and furthermore does not permit the “snap-over effects” that drastically impair the lubricant wedge effect, so that even under more difficult operating conditions, targeted optimal variation of the wedge angle, adapted to the operating conditions, in each instance, is always guaranteed, and great reliability of the axial sliding bearing, at a long useful lifetime, can be guaranteed, while simultaneously expanding the optimal dynamic supporting range.
