Embodiment Construction

[0029] Various embodiments of the invention will be described in detail, one or more examples of which are depicted in the accompanying drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. For example, features illustrated or described as part of one embodiment can be used or combined with other embodiments to yield yet a further embodiment. It is meant that the present invention includes such modifications and changes.

[0030] figure 1 An embodiment of the invention according to the first aspect of the invention is shown. Wherein, the inclination drive system includes an adjustment drive device 1 and an emergency drive device 2 . The adjusting drive 1 and the emergency drive 2 comprise separate drive trains. Thus, the complexity of the separate drive train components 1 , 2 is reduced compared to the case where the adjustment drive and the emergency drive share a drive train.

[0031] The adjusting drive 1 comprises ...

Abstract

A pitch drive system for a wind turbine is provided, comprising an adjustment drive (1) for adjusting the pitch of rotor blades of the wind turbine during normal operation, the adjustment drive comprising at least one drive chain ( 3, 4, 5); and an emergency drive (2) for tilting a rotor blade in an emergency, said emergency drive comprising at least one drive chain (8, 9, 10), wherein the emergency drive At least one transmission chain (8, 9, 10) of (2) is independent of at least one transmission chain (3, 4, 5) of the adjustment drive (1).

Description

technical field [0001] The present invention relates to a pitch drive system for a wind turbine, in particular to such a pitch drive system comprising adjustment drive means for adjusting the pitch of the rotor blades of said wind turbine during normal operation, and in emergency situations The emergency drive that tilts the rotor blades. The invention also relates to a wind turbine with a pitch drive system comprising an adjustment drive and an emergency drive. Background technique [0002] Typically, modern wind turbines have rotor blades with adjustable pitch angles. The rotor blades can be rotated about their longitudinal axis by pitch drives placed on the rotor hub. Typically, the pitch drive is electrically or hydraulically actuated. By adjusting the inclination angle of the rotor blades, the power generation of the wind turbine can be controlled, and the aerodynamic braking of the rotor can also be achieved. Specifically, braking torque is generated when the rotor...
