Claims (9)
- ころがり軸受における固体伝導音の検出方法であって、ころがり軸受に設けられる圧力又は伸びに感応するセンサの測定信号(M)が、望ましくない信号成分を除去する周波数フィルタへ供給されるものにおいて、周波数フィルタ出力信号のディジタル値から、第1の分散値が計算され、周波数フィルタ出力信号の別のティジタル値から、少なくとも1つの第2の分散値が求められ、これらの少なくとも2つの分散値(新しい分散値、古い分散値)から、帰納的計算により、これらの分散値の得られる算術平均が計算され、得られた算術分散平均値が所定の分散閾値(Vsw)を超過すると、ころがり軸受の機械的損傷により生じる固体伝導音現象と評価され、閾値超過の周波数が、軸受の回転数及び幾何学的状態を知ると、損傷の発生場所(外レース、内レース、ころがり体)に一義的に対応づけられることを特徴とする、方法。
- 適応定常Cが、1より小さく0より大きい値を持っていることを特徴とする、請求項1に記載の方法。
- 新しい分散の値が測定信号の真の分散の評価値として評価され、この評価値がころがり軸受における固体伝導音現象の存在を示すことを特徴とする、請求項6に記載の方法。
- 高い新しい分散値がころがり軸受における固体伝導音の存在の高い確率を表わすことを特徴とする、請求項6又は7に記載の方法。
- 高い新しい分散値がころがり軸受における大きい損傷を表わすことを特徴とする、請求項6又は7に記載の方法。
