<p>With three-bladed windmills, there is the disadvantage that the assembly between the wing hub and the main shaft is rigid. All of the hub's various loads and vibrations are hereby transferred directly to the main shaft, which is hereby exposed to a load which is determinative for its size, and which involves larger bearings and dimensions. According to the invention, this problem is remedied by means of a flexible intermediate link between the hub and the shaft. The loads, which are absorbed by the flexible link, are thus neutralized, hereby sparing the shaft. Furthermore, a spring element can be introduced in the link, so that a controllable damping of the loads can take place depending on the spring tensions.</p> |
