Abstract
Provided is a fluid film bearing, especially for a rotor hub in a wind turbine, including an inner part that supports a rotating outer part, wherein the inner part includes multiple radial pads distributed along the outer circumference of the inner part, each of the radial pads having at least one radial pad sliding surface, wherein the radial pad sliding surfaces support at least one outer part sliding surface of the outer part in the radial direction.

A fluid film bearing, especially for a rotor hub in a wind turbine, comprising an inner part that supports a rotating outer part, wherein the inner part comprises multiple radial pads distributed along the outer circumference of the inner part, each of the radial pads having at least one radial pad sliding surface, wherein the outer part has multiple outer part sliding surfaces, wherein the radial pad sliding surfaces support at least one of the outer part sliding surfaces of the outer part in the radial direction, wherein the inner part additionally comprises a first and a second group of axial pads distributed along the circumference of the inner part, each of the axial pads having an axial pad sliding sur-face, wherein the axial pad sliding surfaces of the axial pads of the first group axially support a first one of the outer part sliding surfaces not supported by the radial pad sliding surfaces and wherein the axial pad sliding surfaces of the axial pads of the second group axially support a second one of the outer part sliding surfaces not supported by the radial pad sliding surfaces, wherein the outer part forms an annular outer section and two annular protrusions extending in the radial direction toward the inner part from the outer section, wherein the outer part sliding surfaces are formed on the annular outer section and the inner faces of the annular protrusions facing each other, wherein the first and second group of the axial pads are arranged between the annular protrusions.
