Patent number: 9915245Abstract: A reinforced pitch bearing of a wind turbine having a first reinforcement plate and a second reinforcement plate is provided. The pitch bearing includes an outer bearing ring and an inner bearing ring, whereby both bearing rings are arranged coaxially to each other, thus comprising a common axis of symmetry. The first reinforcement plate is arranged at a first axial end of the pitch and the second reinforcement plate is arranged at a second axial end of the pitch bearing. The reinforcement plates are arranged substantially parallel to each other and the pitch bearing includes further means for reinforcement arranged in between the first reinforcement plate and the second reinforcement plate. The invention also relates to a wind turbine having at least one rotor blade and at least one pitch bearing, pivotably connecting the rotor with a hub of the wind turbine.Type: GrantFiled: April 6, 2015Date of Patent: March 13, 2018Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Srinivas Ratna Kosuri, Christian Laursen, Mujahid Shaik, Akhilesh Shukla

Patent number: 9551325Abstract: A wind turbine flange connection between a hub and a nacelle of the wind turbine, a wind turbine, a wind turbine hub and a wind turbine nacelle is provided. The hub of the wind turbine comprises a first flange and the nacelle of the wind turbine comprises a second flange. The first flange and the second flange are connected to each other by a number of connection means, to transfer forces between the first flange and the second flange. The first flange comprises a plurality of holes and the second flange comprises a plurality of holes corresponding to the holes in the first flange. Shear pins are arranged in the holes in the flanges to transfer rotational forces between the hub and the nacelle.Type: GrantFiled: March 26, 2014Date of Patent: January 24, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henning Ebbesen, Akhilesh Shukla

Patent number: 9273732Abstract: A bearing with a supporting element, wherein the bearing is suitable for connecting a rotor blade of a wind turbine with a hub of the wind turbine is provided. The bearing comprises a first ring, which is arranged and prepared to be connected with the hub, and a second ring, which is arranged and prepared to be connected with the rotor blade. The rotor blade is rotatable with regard to the hub around a rotor blade axis of rotation. Furthermore, the bearing comprises a supporting element for supporting the first ring, in particular against deformation. The supporting element is arranged and prepared to be attached to the first ring with a first fixing element and to the hub with a second fixing element. A method of supporting a first ring of a bearing is also provided.Type: GrantFiled: March 7, 2014Date of Patent: March 1, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henning Ebbesen, Akhilesh Shukla
