The vibration was detected by the piezoelastic accelerometer mounted on the bearing housing and was recorded by the magnetic tape recorder which was controlled by a microcomputer. In total twenty-seven bearings were tested, and flaking failures were generated in twenty-five bearing, nine on the outer races, nine on the inner races and seven on the balls. In most cases, flaking grew gradually with obvious changes of vibratory characteristics, thus enabling the early detection of the defects in the bearings. However in some bearings, flakings were generated suddenly, 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: NALTR0601000","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-601","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":"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":"西尾, 健二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"星谷, 昌二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮地, 敏雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NISHIO, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HOSHIYA, Shoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYACHI, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"naltr00601.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00601.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44855/files/naltr00601.pdf"},"version_id":"87cb5a61-c2b6-4446-8a67-ebc85a45d721"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"振動の監視による転がり軸受の故障の早期発見に関する研究(第1報40番モータ油潤滑玉軸受)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"振動の監視による転がり軸受の故障の早期発見に関する研究(第1報40番モータ油潤滑玉軸受)"}]},"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":"44855","relation_version_is_last":true,"title":["振動の監視による転がり軸受の故障の早期発見に関する研究(第1報40番モータ油潤滑玉軸受)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:49:41.817483+00:00"}
