A wind turbine includes a nacelle with a main bearing tilted with its rotation axis towards the horizontal axis and including an inner and outer ring, wherein the main bearing is a slide bearing and the inner ring is stationary while the outer ring rotates, with the main bearing being lubricated, and with the outer ring including a first and a second sealing means, wherein the first sealing means is due to the tilt of the main bearing lower than the second sealing means, wherein a stationary leakage lubrication fluid collection means is provided adapted for collecting lubrication fluid, wherein the outer ring is provided with one or more axial bores connecting a leakage lubrication fluid collection area to the leakage lubrication fluid collection means and wherein each sealing means includes a groove accommodating a sealing element and a sealing element carrier ring.

Wind turbine

A fluid film bearing for a rotor hub of a wind turbine is provided including a first part and a second part rotatably coupled to each other about a longitudinal axis. The first part includes an annular first sliding surface extending in the circumferential direction of the fluid film bearing along the first part. In addition, the second part includes a support structure and a first group of bearing pads coupled to the support structure and having a bearing pad sliding surface configured to slide on the first sliding surface. In addition, the support structure includes a plurality of openings for replacing the bearing pads.
