A multiple generator wind turbine comprises two generators, each of the two generators including one tubular rotor and one substantially tubular stator, each stator being supportable by a support tower; each rotor and stator carrying one of mutually opposed magnetic field generators and windings and being substantially concentric such that each stator or rotor lies at least partly within the other of stator and rotor and such that the mutually opposed magnetic field generators and windings face each other; a blade arrangement on a side of one of the at least two generators opposite the support structure, the blade arrangement including a hub attached to a rotor of the one of the two generators, the blade arrangement further including at least two blades extending radially from and supported by the hub; and a single bearing mounted diametrally between the stator and the rotor of the one of the two generators.

Eine Baureihe von Getriebebauteilen umfaßt ein in sämtlichen Getriebebauteiletypen der Baureihe verwendetes Basismodul, das einen speisenden Primärteil als Sendeeinheit und einen Sekundarteil als Empfangseinheit. Sendeeinheit und Empfangseinheit sind durch zumindest einen Luftspalt voneinander getrennt, jeweils in einem im wesentlichen ring- oder scheibenförmigen Träger fixiert und induktiv, kapazitiv, optisch oder funkgebunden miteinander gekoppelt. Getriebebauteiletypen sind jeweils durch eine typindividuelle Anzahl in Umfangsrichtung an den Trägern verteilt angeordneter Basismodule gekennzeichnet. Außerdem sind Getriebebauteiletypen jeweils durch eine typindividuelle Anzahl radial zueinander versetzt angeordneter Reihen von Basismodulen gekennzeichnet. Darüber hinaus sind Getriebebauteiletypen jeweils durch eine typindividuelle Anzahl axial zueinander versetzt angeordneter Reihen von Basismodulen gekennzeichnet.

A machining center is designed for machining a hub having faces that are spaced one hundred and twenty degrees from one another around the hub. The machining center includes a table for supporting the hub when it is being machined and three vertical gantries arranged around the table that are spaced one hundred and twenty degrees from one another. The gantries have X and Z axis drives for moving the gantries parallel to the faces of the hub and toward and away from the hub. At least one machining member is mounted on each of the gantries for vertical movement on the gantry and stroke drives are provided for the machining members for driving the machining members toward the center axis of the hub, allowing the three faces of the hub to be machined simultaneously by the machining center.

The present invention relates to a fluid intake assembly (100) adapted for use with a turbo-machine (200). The invention provides an efficient fluid inlet assembly (100) comprising a casing (120) adapted to guide fluid into the turbo-machine (200). The casing (120) comprises an inner wall (130), the inner wall (130) having a lining (140) of a resin infused composite material. The invention also provides a method of producing a fluid intake assembly (100) for use with a turbo-machine (200).
摘要:
A wind turbine comprises a rotor with a certain number of blades, a stator supporting the rotor in such a way that the rotor may rotate on the turbine axis for generating electric energy and a shroud extending circumferentially around the stator and the rotor and supporting the stator so as to define an air channel of a certain air channel diameter at an inlet portion of the shroud. The shroud has a maximum outer diameter such that the air channel diameter is comprised in the range from 0.82 to 0.9 times the maximum outer diameter. Furthermore, the shroud has a length in direction of the turbine axis that is comprised in the range from 0.1 to 0.25 times the outer diameter.

The invention relates to wind power installations having a nominal power for which a drive train is provided, which is designed for a pre-determined torque. In order to reach the nominal power, the rotor blades and the parameters of the operating mode are selected such that they are adapted to the drive train.

The invention relates to a wind power current generator comprising a bearing (2), a stator (3), which is fixed to the bearing (2), a rotor (4) that can rotate in relation to the stator (3), a hub (5) connected to the rotor (4) and at least two blades radially extending away from the hub (5). According to the invention, the stator (3) and the rotor (4) are formed by tubular sections that are concentric to one another, on whose opposing surfaces permanent magnets (7) and windings (8) are placed, and which extend over the magnets and out from the windings in order to accommodate an antifriction bearing on at least one side.

This invention provides a modularized ocean energy generating device including an outer frame, at least four inner frames, and at least four hydraulic generator modules. The at least four inner frames are detachably disposed in the outer frame. The at least four hydraulic generator modules are disposed in the at least four inner frames, respectively. The modularized ocean energy generating device in the invention includes at least four built-in modules, and the hydraulic generator modules can be distributed in an array. By the detachable inner frames and the outer frame, modularized assembly and installation can be realized, thereby greatly reducing preserving and installing costs.
