| 20080199309 | Removable bearing arrangement for a wind turbine generator - A wind generator having removable change-out bearings includes a rotor and a stator, locking bolts configured to lock the rotor and stator, a removable bearing sub-assembly having at least one shrunk-on bearing installed, and removable mounting bolts configured to engage the bearing sub-assembly and to allow the removable bearing sub-assembly to be removed when the removable mounting bolts are removed. | 08-21-2008 |
| 20090169393 | WIND TOWER AND METHOD OF ASSEMBLING THE SAME - A method of assembling a tower for use with a wind turbine is provided. The method includes providing a plurality of tower segments. Each tower segment includes a first interface and a second interface. The method also includes bonding the first interface of a first tower segment to the second interface of a second tower segment using an adhesive composition. | 07-02-2009 |
| 20100139092 | SHAFT FOR WIND TURBINE GENERATOR AND METHOD FOR ASSEMBLING WIND TURBINE GENERATOR - A method of assembling a wind turbine generator includes fabricating a first portion of a shaft from a first steel alloy having a first strength property value. The method also includes fabricating a second portion of the shaft from a second steel alloy having a second strength property value. The first strength property value is greater than the second strength property value. The method further includes welding the second portion of the shaft to the first portion of the shaft. | 06-10-2010 |
| 20110138704 | TOWER WITH TENSIONING CABLES - A tower, which may be used for a wind turbine, is provided. The tower includes at least one concrete tower section having a plurality of tensioning cables. The tensioning cables are configured to induce a compressive force on the concrete tower section. The tensioning cables are spaced from an exterior surface of the concrete tower section by a substantially uniform distance. | 06-16-2011 |
| 20110138707 | TOWER WITH ADAPTER SECTION - A tower is provided having a foundation, at least one concrete tower section located above the foundation and one or more upper tower sections. An adapter section is located between the concrete tower section and one of the upper tower sections. The adapter section is connected to one of the upper tower sections by a fastening system and to the foundation by a plurality of tensioning cables, which are configured to induce a compressive force on the concrete tower section. The fastening system and the plurality of tensioning cables are substantially vertically aligned so that tower loads are transmitted from the upper tower sections to the plurality of tensioning cables. | 06-16-2011 |
| 20110138721 | WIND TURBINE TOWER ASSEMBLY AND METHOD FOR ASSEMBLING THE SAME - A wind turbine tower assembly includes a tubular section having a first longitudinal axis and a base section assembly including a plurality of legs. The base section assembly is configured to be assembled into a base section having the legs coupled together at an interface such that the base section has a second longitudinal axis and such that the legs are obliquely oriented relative to the second longitudinal axis at the interface, wherein the base section is configured to support the tubular section on the legs and in substantially coaxial alignment with the base section. | 06-16-2011 |
