Vibration was detected by a piezoelectric accelerometer mounted on the bearing housing and was recorded by a magnetic tape recorder which was controlled by a microcomputer. In total, twenty-seven bearings were tested, and flaking failures were generated in twenty-six of them; nineteen on the outer races, five on the inner races and two on the balls. In most cases, flakings grew gradually with obvious changes of vibration, thus enabling the early detection of the defects in the bearings. However, in some bearings, flakings were generated very rapidly, limiting the usefulness of the condition monitoring.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0675000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-675","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所原動機部"},{"subitem_text_value":"航空宇宙技術研究所宇宙研究グループ"},{"subitem_text_value":"航空宇宙技術研究所原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Space Technology Research Group, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"星谷, 昌二"}],"nameIdentifiers":[{"nameIdentifier":"472023","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"関, 勝美"}],"nameIdentifiers":[{"nameIdentifier":"472024","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西尾, 健二"}],"nameIdentifiers":[{"nameIdentifier":"472025","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮地, 敏雄"}],"nameIdentifiers":[{"nameIdentifier":"472026","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HOSHIYA, Shoji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472027","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SEKI, Katsumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472028","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NISHIO, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472029","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MIYACHI, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472030","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr00675.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00675.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44932/files/naltr00675.pdf"},"version_id":"6c2ed8a2-2368-402e-a728-df6733dca4b2"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"An Investigation of the Early Detection of Defects in Ball Bearings by the Vibration Monitoring(Second Report, Grease Lubricated Ball Bearings)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An Investigation of the Early Detection of Defects in Ball Bearings by the Vibration Monitoring(Second Report, Grease Lubricated Ball Bearings)","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44932","relation_version_is_last":true,"title":["An Investigation of the Early Detection of Defects in Ball Bearings by the Vibration Monitoring(Second Report, Grease Lubricated Ball Bearings)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:48:17.724262+00:00"}
