Abstract

The present invention relates to a hub for a turbine, in particular a wind turbine for a wind turbine generator. The hub (2) is the holder for at least one turbine blade (1) and is connected to a rotatable turbine shaft (3) through a hinge member, which permits a limited movement of the hub in relation to the turbine shaft (3) and comprises a bearing (12) and a flexible teeter stop (13, 15). The flexible teeter stop (13, 15) comprises spring elements (13) which interact with a reaction arm (15) extending from said turbine shaft (3). The spring elements (13) and the bearing (12), respectively, are disposed in the hub (2) adjacent opposite sides of the periphery of the hub. The invention also relates to a wind turbine generator with such a hub.
