PROBLEM TO BE SOLVED: To provide an abnormality detection method for detecting an abnormality by measuring the oscillation of a rolling bearing, wherein the presence or absence of the abnormality of a rolling bearing is precisely detected without receiving the influence of a disturbance input.SOLUTION: An abnormality detecting method for a wheel rolling bearing detects the presence or absence of the abnormality of a rolling bearing 12 for supporting an air-filled tire 25 rotationally. The method measures the vibration value of the rolling bearing 12 and the air pressure of the tire 25, but does not determine the presence or absence of the abnormality due to a vibration value, when the air pressure fluctuates over a predetermined reference value.SELECTED DRAWING: Figure 1

    【課題】転がり軸受の振動を測定して異常を検出する異常検出方法において、外乱入力の影響を受けず、転がり軸受の異常の有無を精度よく検出する。【解決手段】空気を充填したタイヤ25を回転支持する転がり軸受12の異常の有無を検出する車輪用転がり軸受の異常検出方法であって、転がり軸受12の振動値を計測するとともに、タイヤ25の空気圧を測定し、空気圧が所定の基準値を超えて変動したときに、振動値による異常の有無の判断を行わない。【選択図】図1
