Rotor bearing housing for wind turbine tower
A rotor bearing housing for a wind turbine tower has been granted a patent (Publication Number: US11920567B2). The housing includes a bearing body with receptacles for rotor bearings at each end, a support body for transmitting force flow to a base element at the tower's end, and is designed as a single-piece body. The geometrical central points of the receptacles are positioned outside the tower's diameter, ensuring stability and structural integrity. The support body has a circular symmetrical shape at the base connection and an elliptical outline above, enhancing its structural strength.
Furthermore, the support body is inclined in a specific direction at both receptacles, ensuring proper alignment and load distribution. The housing design allows for direct support of the rotor bearings by the support body, with a flowing transition between the bearing body and support body. The rotor shaft extends through the bearing body, with one receptacle facing the rotor and the other facing away. The housing also includes rolling bearings for mounting the rotor shaft, providing stability and smooth operation for the wind turbine.
