RADIAL ROLLER BEARING, IN PARTICULAR FOR STORING SHAFTS IN WIND TURBINE TRANSMISSIONS

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, roller bodies are replaced by hollow rollers that have a greater diameter and a smaller elasticity module than the roller body bodies ensuring, when the radial roller bearing is in the load-free state, a permanent contact with the bearing rings, and a permanent drive of the bearing cage and the roller bodies have kinematic rotation. The hollow rollers, by a defined dimensioning of their internal diameter in relation to their external diameter for the dimensioning of the radial roller bearing, have the same bearing capacity as the roller bodies.
