  • automatic diagnosis of Antifriction Bearings using vibration analysis and fuzzy logic
    IFAC Proceedings Volumes, 1997
    Co-Authors: B Geropp, Steffen Schneider, Andreas Seeliger
    Abstract:

    Abstract A powerful instrument for condition monitoring for diagnosis of machines is given by the vibration analysis. The envelope analysis as a part of it turned out to be a very effective method for diagnosis of anti friction Bearings. Different bearing failures lead to different patterns of the envelope spectrum. Checking the amplitudes of characteristic bearing frequencies is mostly not sufficient for a reliable diagnosis. Therefore human experts compare the pattern of the spectrum with typical patterns of bearing defects. In this paper a fuzzy system is presented which imitates this action of human experts. The knowledge which is necessary for the diagnosis will be stored in the fuzzy rules. In this manner, the system is able to automatically recognize typical bearing defects as well as other kinds of machine failures. The input parameters of the fuzzy system are extracted by an extensive data preprocessing. The presented fuzzy-system is used in different applications in mining and steel industry.

  • a low cost tool for diagnosis of Antifriction Bearings
    IFAC Proceedings Volumes, 1994
    Co-Authors: Andreas Seeliger, B Geropp, H W Kessler
    Abstract:

    Abstract Sound conducted through solids has been used to diagnose failures of machines for a long time. Many companies offer expensive equipment to measure and analyse vibrations. Faults in Antifriction Bearings can be detected at an early stage of failure using this equipment In this paper the effect of faults in Antifriction Bearings on signal analysis methods will be discussed. The results lead to a new tool for low cost diagnostic equipment which is based on enveloped signals and uses a low cost acceleration sensor.

  • Sleeve versus Antifriction Bearings: selection of the optimal bearing for induction motors
    Record of Conference Papers. IEEE incorporated Industry Applications Society. Forty-Eighth Annual Conference. 2001 Petroleum and Chemical Industry Tec, 1
    Co-Authors: W.r. Finley, Mark Hodowanec
    Abstract:

    The decision between which bearing type to utilize is not always easy or even obvious. There is no choice in bearing selection on small motors (less than 200 HP), where only anti-friction Bearings are readily available. Likewise, a choice does not always exist on larger motors in excess of 2000 HP, where various design requirements leave only the sleeve bearing (or tilting pad bearing) as a viable option. On intermediate size motors, a choice will have to be made. In general, anti-friction Bearings (AFB) are less expensive, and result in a more compact motor. However, there are potential disadvantages associated with anti-friction Bearings. The 'best' bearing decision depends on the details of the particular application. This paper explores the advantages/disadvantages of both types of Bearings. Additionally, it provides guidelines to help select the best bearing for the application. Judicious selection of Bearings will result in motor purchasing savings without sacrificing process reliability.
