Wind power turbine and method of removing a bearing from a wind power turbine

摘要

An electric energy producing wind power turbine having a nacelle, an electric generator having a stator and a rotor, a rotary assembly connected to the nacelle to rotate about an axis of rotation, and a bearing located between the rotary assembly and the nacelle, the nacelle having a first sector, which is located at the bearing, which is removable from the nacelle, and which is configured to form, when removed, an opening in the nacelle to allow passage of the bearing.

主权项

1. An electric energy producing wind power turbine comprising:
a nacelle; an electric generator having a stator and a rotor; a rotary assembly connected to the nacelle and configured to rotate about an axis of rotation; and a bearing located between the nacelle and the rotary assembly; wherein the nacelle includes:
(i) a first partially annular sector which, in use, extends about the bearing and is located adjacent to the bearing, the first partially annular sector is removable from a remainder of the nacelle, and the first partially annular sector is configured to form, when removed, an opening in the nacelle to allow passage of the bearing, and(ii) a second partially annular sector complementary to the first partially annular sector and connected to the first partially annular sector about the axis of rotation to form a ring configured to support the bearing.
