PROBLEM TO BE SOLVED: To provide a bearing for railway vehicle abnormality detection device which improves durability against an external force and an impact of a device and capable of improving the reliability of the device.SOLUTION: This bearing for railway vehicle abnormality detection device is a bearing for railway vehicle abnormality detection device for detecting the abnormality of a rolling bearing assembled into a journal box disposed in a truck of the railway vehicle, and includes a detection element 13 for detecting the operation state of the rolling bearing; a processing circuit 14 for converting a physical quantity detected by the detection element 13 into an output signal; and a power supply 3 for applying a voltage to the detection element 13 or the processing circuit 14. Power supply bypass capacitances C1 to C4 are provided between a power supply line L1 of a voltage application object in the detection element 13 and the processing circuit 14 and a GND line L2. These power supply bypass capacitances C1 to C4 are the capacitances of a film type.
【課題】 外力や装置の衝撃に対する耐久性を改善し、装置の信頼性を向上することができる鉄道車両用軸受異常検知装置を提供する。【解決手段】 この鉄道車両用軸受異常検知装置は、鉄道車両の台車に設けた軸箱に組み込まれる転がり軸受の異常を検知する鉄道車両用軸受異常検知装置であって、転がり軸受の運転状態を検出する検出素子13と、検出素子13で検出した物理量を出力信号に変換する処理回路14と、検出素子13または処理回路14に電圧を印加する電源3とを備える。検出素子13および処理回路14における電圧印加対象の電源ラインL1とGNDラインL2の間に、電源バイパスコンデンサC1〜C4を設け、この電源バイパスコンデンサC1〜C4が、フィルムタイプのコンデンサである。【選択図】 図4
