Embodiment Construction

[0022] The blades 1 of the wind turbine rotor, which are only partially shown in FIG. 1, drive a hub 3 which also receives all the additional forces and torques generated by the rotor. A rotor shaft 9 is mounted via a front rotor bearing and a rear rotor bearing 7 , and the rotor load is transmitted to a frame 11 .

[0023] The vertical bearing 13 then transmits the load into the wind power plant tower 15 . Thus, external aerodynamic loads and mass loads of the rotor are introduced into the tower without necessarily passing through the gear transmission or the generator in whole or in part. Via a connection 17 , for example a shrink ring, the gear transmission 19 is connected to the rotor shaft 9 in a torque-resistant manner.

[0024] The gear transmission housing 21 is supported by the elastic member 23 with respect to a base plate 25 . These elastic elements 23 remain absorbing torque fluctuations, structural deformations caused by external loads do not lead to loads on th...

Abstract

A wind energy plant comprising a rotor, a rotor shaft, a gear, and a generator, the generator embodied as a ring concentrically embracing the gear.

Description

technical field [0001] The invention relates to a wind power plant with a concentric gear drive / generator arrangement. Background technique [0002] A number of drive train arrangements are known for wind power plants. With the exception of gearless machines, most machines consist of a combination of a gear transmission and a generator. In wind power plants, gear drives and generators are traditionally arranged in series as separate components on a frame. In the event of damage, these components can be exchanged individually, but the overall structure is longer and therefore heavier and more expensive. [0003] In EP 811 764 B1 the gear transmission and the generator are housed in a common housing in direct connection, the gear transmission being a single-stage planetary gear transmission, placing the housing directly on the tower. The gear drive and the generator have roughly the same diameter, and the two components are arranged in a direct connection, which results in ...
