METHOD TO MOUNT A ROLLING BEARING ON A WIND TURBINE SHAFT AND A WIND TURBINE BEARING ASSEMBLY

摘要

The invention is a method of mounting a rolling bearing onto a wind turbine rotor shaft, wherein the bearing includes an outer ring, an inner ring and rolling elements disposed between the rings, and wherein the inner ring provides an inner circumferential surface, having a frustoconical profile. The rolling bearing is mounted on a corresponding conical seat on the rotor shaft by the frustoconical inner circumferential surface. The method includes: pressing a liquid in-between the inner circumferential surface of the inner ring and the conical seat to facilitate the driving up of the rolling bearing on the conical seat, driving up the rolling bearing on the conical seat by an axial force acting on the rolling bearing, wherein the liquid is pressed in-between the two surfaces at an axial end portion of the inner circumferential surface. Furthermore, the invention regards a bearing assembly.
