    摘要： A variable ratio transmission having an infinitely variable ratio, for enabling a tidal turbine (10) or the like running at relatively low but continuously varying speeds, to drive smoothly a constant speed machine, such as a synchronous generator or the like, without excessive transient torques. A preferred transmission includes a primary differential gear train (120), having a driven input (50), and a driving output, wherein the ratio of the input speed to output speed is variable, and wherein said ratio is governed by the reaction torque provided by speed controlling gearing (150) within the primary differential (120), the transmission including a secondary differential gear train (220), which is in rotational communication with the input (50) via a first route (115), and is in rotational communication with the speed controlling gearing (150) via a second different route (125), wherein the secondary differential gear train includes two parallel power paths.

    摘要： A differential gearing for an energy generation plant, in particular for a wind power station, has three drives and outputs, a first drive being connected to a drive shaft of the energy generation plant, one output being connected to a generator (8), and a second drive being connected to an electrical machine as differential drive (6). The transmission ratio of the differential gearing (3) can be fixed at 1 by way of a brake (20).

    摘要： The invention relates to a wind energy plant comprising a rotor having a rotor hub which is mounted on a gondola and a plurality of rotor blades. An electric generator is connected to the rotor. The invention also relates to an electric drive device which is designed as a direct drive and used to adjust a rotor blade which is arranged in a concentric manner on the rotor hub in relation to rotor blade bearing and a permanently excited synchronous motor. A stator of the synchronous motor comprises a coil body which is mounted on the motor hub. A rotor of the synchronous motor is arranged at an axial distance with respect to the stator for forming an axially extending air gap. Said rotor also comprises a permanent magnet arrangement on a support plate which is connected to a rotor blade shaft.
