Abstract: A tool measures relative concentricity deviations in a confined space between two circumferential elements, such as a turbine rotor and a turbine diaphragm. The tool includes a housing, and a sensor coupled with the housing that measures a distance from the housing to one of the two circumferential elements. An axial spring plunger is connected to the housing, and a radial spring plunger is connected to the housing and arranged orthogonal to the axial spring plunger. The tool also includes a sliding or rolling surface on a side of the housing opposite from one of the axial spring plunger and the radial spring plunger.

Abstract: A wind turbine includes a nacelle, a generator housed with the nacelle, a rotor having a rotatable hub with at least one rotor blade mounted thereto, at least one shaft rotatably coupled to the hub for driving the generator, and a rotor lock arranged with the shaft(s) for locking the shaft(s) in a locked position. The wind turbine also includes a bolted-joint connection at an interface between the hub and the shaft(s). The bolted-joint connection includes a first plurality of fasteners extending through the hub, the shaft(s), and the rotor lock. As such, a load transfer path from the hub to the shaft(s) travels through each of the hub, the shaft(s), and the rotor lock so as to increase a load capacity of the interface.

Abstract: A method for detaching or installing a rotor blade from or to a hub of a wind turbine includes positioning the rotor blade toward a ground location between a three o'clock position and a nine o'clock position. The method also includes mounting a mechanical arm to an uptower location of the wind turbine. Further, the mechanical arm includes a torqueing tool at a distal end thereof. Thus, the method also includes removing or installing, via the torqueing tool, each of the plurality of hub fasteners so as to detach or attach the rotor blade from or to the hub.

Abstract: An external ladder assembly for a nacelle of a wind turbine includes at least one ladder having parallel side legs and a plurality of rungs arranged between the parallel side legs. The ladder assembly also includes a ladder platform arranged with the ladder and configured for placement atop the nacelle. Further, the ladder assembly includes a mounting assembly for affixing the ladder platform atop the nacelle. More specifically, the mounting assembly is adjustable between multiple positions so as to level the ladder platform atop the nacelle. Thus, the ladder assembly provides access to one or more uptower, external features of the wind turbine.
