However slight the friction of rolling bearings may be, when such bearings are applied in industrial instruments, the properties in the instruments are important factors in their accuracy, sensibility and performance. This experiment has been made in order to investigate the kinetic fricfional moment of a rolling steel ball, to record the movement of the ball along a horizontal V rail from slowmotion to standstill on the film. Experiments contributed to obtain the mechanism for friction in bearings. The effects of various materials used in the rails, i. e., the elasticity and hardness of the materials and the effect of lubrication have been investigated. Experimental results are roughly summarized as follows : 1) When the contact pressure between the ball and the rail are within a elastic limit, the frictions are mainly in fluenced by the Young's Modulus, but when out of its elastic limit, the frictions are mainly effected by the Shore's hard ness. 2) Oil will surely increase the factional moment. 3) Friction is created, to a large extent, by deformation between contact surfaces caused by pressure. 4) In general, frictional moments gradually increase with retardational motion till at last max. value of friction is reached uniquely. The more the friction is, the more distinct is this tendency. 5) As the amount of rolling friction is small, the factors of the friction come to be numerous, and so the reproducibility of experiments are more difficult than those of sliding experiments.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大學紀要 (4): 181-195(1953)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00411443","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"宮入,  武夫"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Shinshu_Bulletin04-10.pdf","filesize":[{"value":"824.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Shinshu_Bulletin04-10.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/17203/files/Shinshu_Bulletin04-10.pdf"},"version_id":"cd2f13aa-4870-42b3-bdaa-b0b376e3ac44"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"静止附近における転り摩擦に関する実験的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"静止附近における転り摩擦に関する実験的研究","subitem_title_language":"ja"},{"subitem_title":"ON THE EXPERIMENTAL STUDY OF ROLLING FRICTION OF BALL IN SLOW MOTION","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1675"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-02-12"},"publish_date":"2010-02-12","publish_status":"0","recid":"17203","relation_version_is_last":true,"title":["静止附近における転り摩擦に関する実験的研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-18T01:38:17.638858+00:00"}
