A clamping apparatus for positioning a main bearing of a wind turbine includes a push component arranged between a main flange of a main shaft of the wind turbine and a cover of the main bearing. Further, the clamping apparatus includes a spacer plate located within a gap between the cover and the main bearing. As such, the push component is configured to apply a force to the cover so as to push the spacer plate against the main bearing such that the main bearing is pushed into and secured in place.

System for electrical energy generation from steam comprising at least one stage, each stage including: a steam-driven rotating toroidal ring; a housing comprising a toroidal cavity for containing the rotating toroidal ring, the housing further comprising at least one steam inlet, the housing further comprising a plurality of steam outlets for removing pressurized steam from the channels for at least a second portion of rotation of the rotating toroidal ring within the toroidal cavity; at least one bearing arrangement comprised by or attached to the housing within the toroidal cavity; and at least one pair of electrical coils, each electrical coil located on the outer surface of the housing at locations diagonally opposite from the other coil of each pair across the axis of the minor radius of the toroidal cavity and within the specific region where a time-varying magnetic field will occur as the rotating toroidal ring rotates.

Systems and methods for the automated non-destructive inspection of wind turbine blades. A motor-driven track that conforms to the shape of the blade moves along its length. At each spanwise position, the motor-driven track is stopped and then while the motor-driven track is stationary, any one of various types of NDI sensors is moved along the track to collect inspection data on the structure. The track is either segmented or flexible in order to conform to the cross-sectional profile of the blade. In addition, tracking the spanwise motion of the motor-driven track along the blade is provided. Optionally, avoiding protrusions on the blade that may be in the way during scanning is provided.

A turbine rotor assembly including a unitary body including at least one inlet for inlet of a fluid into the rotor assembly and a plurality of flow channels extending through the unitary body and terminating in an outlet portion, the at least one inlet in fluid communication with each of the plurality of flow channels.

A magnetic piston shoe pair for an axial piston pump and the motor includes: pistons, coil suites, piston shoes and a swash plate, wherein the interior of the coil suite is a closed coil; the bearing surface that the end surface of the swash plate abuts the piston shoe is provided with micro-molding holes; the micro-molding holes are hemispherical; the back surface of the swash plate is provided with a primary iron core and two secondary iron cores; the iron cores are wound with coil; the coil is connected to an external alternating current power supply. When the pump/motor is working, the coil is energized to generate a magnetic field, thereby adsorbing the piston shoe on the swash plate. Meanwhile, the coil suite generates an inductive magnetic field.
