  • Patent number: 9939023
    Abstract: A bearing assembly includes a roller bearing connected with a plate-shaped bearing support. The bearing support has a receiving bore for an outer ring of the roller bearing, and the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support. The two affixing plates clamp the outer ring at two clamping surfaces. An axial spacing of the first and second end sides of the bearing support is smaller than an axial spacing of the clamping surfaces of the outer ring, and a spring element configured to act in the axial direction is disposed between one of the two affixing plates and the bearing support.

  • Patent number: 9835203
    Abstract: A bearing arrangement is disclosed having a bearing and a bearing support. The bearing is coupled to the bearing support at an axial side. The bearing provides first and second bearing rings that define a bearing interior there between. A first groove is formed at the first bearing ring's radial side facing the second bearing ring. A coupling element is arranged at the bearing's axial side facing the bearing support. The coupling element includes a first, preferably nose-shaped, radial protrusion that is in engagement with the first groove, and a second radial protrusion, which at least partially encompasses the bearing support at a side facing away from the bearing, so that the coupling element fastens the bearing to the bearing support. A coupling element for such a bearing arrangement is also provided.

  • Patent number: 9702403
    Abstract: A non-locating bearing assembly is configured to rotatably support a shaft relative to a housing while permitting relative axial displacement of the shaft relative to the housing. The bearing assembly includes a bearing having inner and outer rings and that is configured for transmitting radial and axial forces, and a bearing support attachable to the housing and including a support section having a partially cylindrical seat surface for receiving one of the inner and outer bearing rings and forming a sliding seat therefor. The sliding seat allows a relative axial displacement between the support section and one of the inner and outer bearing rings. A spring is disposed on or in the bearing support for generating a force in the axial direction between the bearing support and the one of the inner and outer bearing rings, and the spring element is formed from a segment of the bearing support.
