Abstract

A wind turbine generator with a bearing system is disclosed. The bearing system includes a lockable connection having a bearing surface and a support surface which surfaces are engaged when the lockable connection is locked. Forces from the shaft are transferred via the bearing into the support through the bearing surface, wherein a support angle of the support surface, relative to a shaft plane formed by rotating the shaft around a first axis, which first axis is perpendicular to the center axis and which first axis is comprised in a vertical plane, is in a range from and including 5 degrees to and including 70 degrees.
