Title: METHOD OF FINISHING A BEARING RING
Abstract:
Method of machining a bearing ring (11, 12) of a wind turbine bearing (1), which method comprises the steps of identifying a number of local hard zones (Z) on a surface (112, 122, 14) of the bearing ring (11, 12); and removing material from the surface (112, 122, 14) such that a bearing ring thickness (hz) in local hard zone (Z) is less than a bearing ring thickness (hN) outside a local hard zone (Z). The invention further describes a machining assembly (3), a wind turbine bearing (1), and a wind turbine (2).
