Central pitch adjustment for wind turbines, has two component assemblies, where former component assembly is in circumferential rotating hub and latter component assembly is in fixed installation part
摘要
<p>The central pitch adjustment has two component assemblies, where the former component assembly is in a circumferential rotating hub (7) and the latter component assembly is in a fixed installation part (14). The component assemblies are connected with each other by a bearing (1) which allows relative rotation. The devices required for the adjustment of the rotor blades (5) are in the fixed installation part. One of the component assembly lies in the rotating hub which determines the angle position of the rotor blades around its longitudinal axis by a control lever (3).</p>
