  • Patent number: 9702816
    Abstract: A detector for oil condition monitoring includes an optical fiber having a first end and a second end having an end face. A sensor body has a gap in which a sample of the oil may be received and a reflecting surface, the second end of the optical fiber being embedded in the sensor body and having an end face spaced from the reflecting surface across the gap. Light emitted from the optical fiber can pass through the sample of oil and be reflected by the reflecting surface back into the optical fiber. By interferometry of the respective signals, the condition of the oil can be determined.

  • 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.
