Rolling bearing

Abstract

The invention relates to a rolling bearing comprising at least one bearing ring and a plurality of rollers, the bearing ring having a raceway for the rollers and at least one lateral rim for axially guiding the rollers. The roller has a front face facing the rim and the rim has a rim bearing surface facing the roller. At least sections of at least the front face or the rim bearing surface are cambered in the direction of the rim bearing surface or the front face, said camber having a logarithmic profile of camber in at least one border section.

Description

technical field [0001] The invention relates to a rolling bearing. The invention will be described with reference to tapered roller bearings, but it is pointed out that the invention is equally applicable in other bearing types such as cylindrical roller bearings or self-aligning roller bearings. Background technique [0002] Roller bearings are known from the prior art which have side ribs opposite the raceways in order to absorb axial load components. Cylindrical roller bearings with flat roller end faces and flat rib surfaces are known from the prior art. Bearings of this type cause the rolling bearing to slide against the edge of the rib (Kantenlauf). A consequence of this type of edge sliding is a reduced service life of the rolling bearing. [0003] Cylindrical roller bearings are also known from the prior art, the end faces of the roller bearings having the shape of a spherical crown. In this rolling element, a central region of the end face is not spherical, bu...
