    摘要： A hub bearing and a seal device therefore are disclosed. In one example, the hub bearing seal device includes inner and outer rings, a ring-shaped seal, and a seal retaining ring. A metallic framework is provided inside the seal. The seal is fixed to the outer ring via the metallic framework and a seal lip edge is provided on the metallic framework of the seal. The seal lip edge is in contact with the seal retaining ring in interference fit. The seal is further provided with another layer of metallic framework having a different thermal expansion coefficient from that of the metallic framework. Together, the metallic frameworks form a bimetallic sheet type framework. During the operation of the seal device, the bimetallic sheet type framework can adjust the amount of interference between the seal lip edge and the seal retaining ring dynamically according to temperature change.

    摘要： A self adjusting instrumented rolling bearing having an outer ring and an inner ring delimiting a rolling chamber and at least one row of rolling elements disposed therein, and a detection device including a sensor integral with the outer ring and a target integral with the inner ring, configured to detect a relative rotation between the outer ring and the inner ring around a central axis. The outer ring has an inner surface in the form of a spherical portion centered about a tilting center of the bearing and forming a rolling surface for the rolling elements. The radius of the inner surface of the outer ring is greater than a distance defined between the tilting center of the bearing and a specific position of the target that is the farthest from the tilting center.

    摘要： A wind turbine with a drive train placed partly or entirely in a nacelle of the wind turbine is provided. The drive train includes an epicyclical gearbox including at least one gear stage having a plurality of planet gears meshing with a sun gear and an annulus gear. The gearbox is used to transfer and speed-up the rotation of a rotor of the wind turbine, as applied to at least one generator of the wind turbine. The drive train further includes at least one locally radial self tracking bearing for enabling the rotation of the rotor in relation to a nacelle structure of the nacelle. The self tracking bearing includes bearing elements for locally transferring loads in both radial directions between one or more bearing rings.
