The decrease in the rotational speed of spindle during the free run period is precisely measured, and the angular deceleration is calculated. The heat quantity generated during the spindle rotation is evaluated as the product of the moment of inertia of spindle, the angular deceleration and the angular velocity. A device is newly developed to measure the rotational speed of spindle accurately for this purpose, which is basically composed of a photo interrupter attached to the spindle and a crystal oscillator of 2.5MHz clock pulse combined with a counter mounted on a personal computer board. The method was applied to evaluate the heat quantity generated in an air spindle, and it was proved that the heat quantity was accurately evaluated with a repeatability error of less than 1%. The heat quantity is obtained to increase by 4% due to an increase in the coefficient of viscosity of air which is caused by the increase in the air temperature.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "40759", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Yokoyama, Kazuhiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "39", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Suzuki, Takamasa"}]}, {"nameIdentifiers": [{"nameIdentifier": "40761", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hirakura, Takashi"}]}, {"nameIdentifiers": [{"nameIdentifier": "40762", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Moriwaki, Toshimichi"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "精密工学会"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.2493/jjspe.61.511", "subitem_relation_type_select": "DOI"}}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110001371842", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 1995 精密工学会"}, {"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN1003250X", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09120289", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "横山, 和宏"}], "nameIdentifiers": [{"nameIdentifier": "40755", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "鈴木, 孝昌"}], "nameIdentifiers": [{"nameIdentifier": "39", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "平倉, 隆史"}], "nameIdentifiers": [{"nameIdentifier": "40757", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "森脇, 俊道"}], "nameIdentifiers": [{"nameIdentifier": "40758", "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": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "110001371842.pdf", "filesize": [{"value": "576.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 576400.0, "url": {"label": "110001371842.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3095/files/110001371842.pdf"}, "version_id": "256dc753-5f8b-4186-aa4a-7c6868f285c9"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "evaluation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "torque", "subitem_subject_scheme": "Other"}, {"subitem_subject": "heat generation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "air spindle", "subitem_subject_scheme": "Other"}, {"subitem_subject": "free-run", "subitem_subject_scheme": "Other"}, {"subitem_subject": "clock pulse", "subitem_subject_scheme": "Other"}, {"subitem_subject": "crystal oscillator", "subitem_subject_scheme": "Other"}, {"subitem_subject": "photo interrupter", "subitem_subject_scheme": "Other"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "回転軸系における摩擦トルク・発熱量の評価に関する研究(第1報) : 評価システムの構成とエアスピンドルの特性評価", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "回転軸系における摩擦トルク・発熱量の評価に関する研究(第1報) : 評価システムの構成とエアスピンドルの特性評価"}, {"subitem_title": "回転軸系における摩擦トルク・発熱量の評価に関する研究(第1報) : 評価システムの構成とエアスピンドルの特性評価", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/27616", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-06-20"}, "publish_date": "2014-06-20", "publish_status": "0", "recid": "3095", "relation": {}, "relation_version_is_last": true, "title": ["回転軸系における摩擦トルク・発熱量の評価に関する研究(第1報) : 評価システムの構成とエアスピンドルの特性評価"], "weko_shared_id": null}
