Abstract:
1. An axial roller bearing comprising: a first annular bearing disk and a second annular bearing disk that are each made of a sheet steel and are arranged at a distance from one another on a common center axis; and a plurality of rolling elements arranged next to one another that (1) roll between axial inner sides of the axial roller bearing, the axial inner sides being implemented as races of the two bearing disks, and (2) are held at uniform distances from one another by a bearing cage, wherein the bearing disks are implemented as disk springs that deflect as a function of load and have races positioned at an angle, and are arranged relative to one another such that the rolling elements have low-friction point contact in the unloaded state of the axial roller bearing and only have full load-bearing line contact with the races in the fully loaded state of the axial roller bearing, wherein angles of incidence of the races of the two bearing disks are designed to be positive, and wherein the races are arranged to be parallel to one another in a straight line.
