Embodiment Construction

[0064] In the following description, "connected", "coupled" and their derivatives mean coupling / joining in operation. It should be understood that there may be any number (including no intermediate components) or combination thereof.

[0065] figure 1 is a schematic illustration of wind turbine 10 according to various embodiments of the invention. The wind turbine 10 includes: a nacelle 12 (which may also be referred to as a wind turbine housing); a support column 13 ; a rotor 14 ; a rotor shaft 16 ; a gearbox 18 ; Wind turbine 10 is configured to convert wind energy into electrical energy, for example output power 22 may be approximately 5 megawatts. Wind turbine 10 may be installed offshore or on land.

[0066] A gearbox 18 and a generator 20 are housed in the nacelle 12 to protect them from the environment (such as may be caused by rain, snow, etc.). The support column 13 is connected to the nacelle 12 and grounded (or may be connected to a fixed floating platform when ...

Abstract

A wind turbine gear box comprises an input shaft arranged to rotate about a longitudinal axis, a non-rotating support component arranged to support the input shaft and one or more bearings located at a position along the longitudinal axis and arranged to provide support between the input shaft and the non-rotating support component. The one or more bearings are arranged to restrict non-rotational movement between the input shaft and the non-rotating support component and the wind turbine gearbox includes no further bearings between the input shaft and the non-rotating support component at other positions along the longitudinal axis.

Description

technical field [0001] The invention relates to a gear box structure and its modules and shafts, in particular to the gear box structure and its modules and shafts applied to wind power generators. The invention also relates to a wind generator comprising the gearbox structure and its modules, shaft. The invention also relates to methods of assembly. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy, usually including a rotor system, a gearbox and a generator. During operation, the wind blows the rotor system into rotation and produces a relatively low frequency high torque input to the gearbox. The gearbox converts the high torque input to the rotor into a relatively high frequency low torque output. The generator is connected to the output of the gearbox and converts the rotational motion into electrical energy. [0003] Wind turbines with relatively high output power (eg, greater than 1 megawatt) are usually very...
