The bearing can further include a first layer on the outer contour of the substrate and/or a second layer on an inner contour of the substrate. The first layer can include a thermally conductive material, and the second layer can include a lubricious material. | 2009-04-02 |
20090087127 | Pitch bearing for wind turbine rotor blades - A pitch bearing for a wind turbine rotor comprises a rotor hub and at least one rotor blade, the pitch bearing comprising a cylindrical inner bearing ring connectable to a rotor blade of the wind turbine rotor, a cylindrical outer bearing ring connectable to the rotor hub of the wind turbine rotor and an annular reinforcement section for reinforcing the outer bearing ring. The annular reinforcement section adjoins the cylindrical outer bearing ring at its radial outer surface. | 2009-04-02 |
20090087128 | Cage, production method for the cage, thrust roller bearing equipped with the cage - A cage includes a radially inward-side annular plate, a radially outward-side annular wall, a plurality of pillar portions, and pockets formed in the pillar portions. Rollers are rotatably retained in the pockets. An inner peripheral surface of the radially outward-side annular wall is formed so as to be oblique toward a radially outward direction. A radially outward-side end surface of each of the rollers has a spherical surface shape. | 2009-04-02 |
