Abstract:
A rolling-element bearing assembly includes a first bearing ring and a second bearing ring that define a bearing interior between them, a plurality of rolling elements disposed in the bearing interior to allow a relative rotation of first and second bearing rings, and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier that is connected to the first bearing ring such that they rotate together and a seal element that is connected to the seal carrier such that they rotate together, and the seal carrier comprises a fiber-reinforced plastic.
Abstract:
A rolling-element bearing assembly includes first and second bearing rings that form a bearing interior between them and a plurality of rolling elements disposed in the bearing interior and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier and a seal element having at least one primary seal lip for sealing the bearing interior and a secondary seal lip for sealing against external contamination. The seal element is connected to the seal carrier such that the primary seal lip and the secondary seal lip abut axially against an axial end surface of the second bearing ring.
Abstract:
A tensioner for preloading a bearing, the bearing including inner and outer bearing rings. The tensioner including a component having a housing and a carrier element that extends radially inwardly from the housing, the outer bearing ring having an outer surface that forms an axially extending radial surface and having a first axial end formed by a radially extending axial surface and directly abutting the carrier element, a support element for supporting the component relative to the inner bearing ring such that a closed force flow arises from the outer bearing ring via the component and the support element, and a sleeve positioned radially between the outer surface of the first bearing ring and the housing such that an inner surface of the sleeve abuts the outer surface of the outer bearing ring and an outer surface of the sleeve abuts a conical surface of the housing.
Abstract:
A system includes a wind turbine having a fixed part and a rotational part and a brake having a brake disk mounted to the rotational part for rotation with the rotational part. At least one brake block is fixed relative to the fixed part and has a friction surface facing the brake disk. The brake block is shiftable between a first position with the friction surface spaced from the brake disk and a second position with the friction surface in contact with and pressed against the brake disk, and the friction surface and/or the brake disk are configured such that pressing the at least one brake block against the brake disk creates a micro-interference fit between the at least one brake block and the brake disk.

Abstract:
A device includes at least one spherical roller bearing that has at least one split bearing ring, the split bearing ring having first and second parts, the device including at least one preloading unit that is configured to exert a force on at least the first part of the bearing ring and at least one control unit that is configured to change the force. The preloading unit comprises a hydroelastic preloading unit and may include an elastic tube for applying a force against the first part of the bearing ring and a pump for pumping a liquid into the tube.
