Embodiment Construction

[0040] figure 1An exemplary wind turbine 2 is shown. Although an offshore wind turbine is shown, it should be noted that the description below is applicable to other types of wind turbines. The wind turbine 2 includes rotor blades 4 mounted to a hub 6 , which is supported by a nacelle 8 on a tower 12 . Wind causes rotor blades 4 and hub 6 to rotate about main axis 14 ( figure 2 ). This rotational energy is transferred to a power transmission system (or “powertrain”) 10 housed within nacelle 8 .

[0041] like figure 2 As shown, the power transmission system 10 includes coupling to the hub 6 ( figure 1 ) of the main shaft 16. The power transmission system 10 also includes a first bearing 18 and a second bearing 20 supporting the main shaft 16 , a bearing housing 22 surrounding the first bearing 18 and the second bearing 20 , and a gearbox having a gearbox planet carrier 26 driven by the main shaft 16 25. A gearbox 25 increases the rotational speed of the main shaft 16 ...

Abstract

A power transmission system (10) for a wind turbine having a main shaft (16) and a support structure (60) drivable by a rotor (6), a gearbox housing (24, 30) and planetary gears rigidly coupled to the support structure (60) Gear box (25) of frame (26). A coupling member (50) connects the planet carrier (26) to the main shaft (16). The main shaft (16) is associated with a radially outwardly projecting set of teeth (74), the planet carrier (24) is associated with a radially inwardly projecting set of teeth (76), and the coupling member comprises teeth associated with the main shaft (16) ( 74) A radially inwardly projecting set of teeth (78) for engagement, the coupling member further comprising a radially outwardly projecting set of teeth (79) for engagement with a set of teeth (76) associated with the planet carrier (26).

Description

technical field [0001] The present invention relates to power transmission systems. More specifically, the present invention relates to power transmission systems for wind turbines. Background technique [0002] Wind turbines typically include a rotor with large blades driven by the wind. The blades convert the kinetic energy of the wind into rotational mechanical energy. The mechanical energy typically drives one or more generators to produce electrical power. Accordingly, wind turbines include a power transmission system to process and convert rotational mechanical energy into electrical energy. The power transmission system is sometimes referred to as the "powertrain" of the wind turbine. The part of the power transmission system from the wind turbine rotor to the generator is called the drive train. Increasing the rotational speed of the wind turbine rotor to the speed required by the generator is achieved through a gearbox between the wind turbine rotor and the gen...
