Abstract:
A radial roller bearing for storing shafts in wind turbine transmissions, which has an external bearing ring with an inner runway, an internal bearing ring arranged coaxial thereto provided with an external runway, and a plurality of roller bodies that displace on the runways between the bearing rings held at regular intervals by a bearing cage. To prevent slip, the roller bodies are replaced by hollow rollers that have a greater diameter and a smaller elasticity module than the roller bodies ensuring, when the radial roller bearing is in the load-free state, permanent contact with the bearing rings, a permanent drive of the bearing cage and that the roller bodies have kinematic rotation. The hollow rollers have a higher bending strength, and their internal cover surface has a maximum surface roughness of Rz≦25 μm preventing localized peaks of tension, without any disaggregation in the axial direction.
