Description
(1)潤滑油とワックスとを、両者の合計量に対し、前記潤滑油を90〜60質量%、前記ワックスを10〜40質量%の割合で含有し、かつ、10〜70℃の範囲の所定の温度で液状になることを特徴とする潤滑剤。
(2)液状になる温度よりも低い温度になった際には、半固体状になることを特徴とする上記(1)記載の潤滑剤。
(3)液状と半固体状の状態変化が可逆的であることを特徴とする上記(1)または(2)記載の潤滑剤。
(4)潤滑油を90〜80質量%、ワックスを10質量%以上20質量%未満の割合で含有することを特徴とする上記(1)〜(3)の何れか1項に記載の潤滑剤。
(5)潤滑油の粘度が5〜200mm2/s(40℃)であることを特徴とする上記(1)〜(4)の何れか1項に記載の潤滑剤。
(6)潤滑油がエステル油で、ワックスがマイクロクリスタリンワックスであることを特徴とする上記(1)〜(5)の何れか1項に記載の潤滑剤。
(7)軸受と、前記軸受に潤滑剤を供給するための潤滑剤供給装置と、前記軸受と前記潤滑剤供給装置とを連結する配管とを備える軸受装置であって、
前記潤滑剤供給装置は上記(1)〜(6)の何れか1項に記載の潤滑剤を貯蔵しており、前記潤滑剤を半固体状で前記配管を流通させ、前記軸受には前記潤滑剤を液状に変化させて供給することを特徴とする軸受装置。
(8)潤滑剤を貯蔵し、配管を通じて前記潤滑剤を軸受に供給するために、軸受外部に設けられる潤滑剤供給装置であって、
上記(1)〜(6)の何れか1項に記載の潤滑剤を貯蔵し、半固体状で前記配管に吐出することを特徴とする潤滑剤供給装置。
(1)試験物品(ワックス系潤滑剤)を2本の試験管(直径30mm、高さ120mm)のA線(高さ55mm)まで入れる。
(2)一方の試験管(液状判断用試験管)を孔穴の無いゴム栓で密栓する。
(3)他方の試験管(温度測定用試験管)を、温度計を付けたゴム栓で密栓する。尚、温度計は、その先端が試験物品の表面より30mmの深さになるように挿入し、試験管に対して直立させる。
(4)2本の試験管を、液状確認温度±0.1℃に保持された恒温槽中に、B線(試験物品の表面よりも30mm上方)が恒温槽の水面下に没するように直立させて静置する。
(5)温度測定用試験管中の試験物品の温度が液状確認温度±0.1℃になってから、10分間そのままの状態を保持する。
(6)液状判断試験管を恒温水槽から水平な台上に直立したまま取り出し、直ちに台の上に水平に倒し、試験物品の先端がB線に到達するまでの時間を計測する。
(7)試験物品がB線に達するまでの時間が90秒以内であるとき、試験物品が「液状」であると判断する。
(8)そして、恒温水槽の温度を種々変更して(1)〜(7)を行い、液状になった温度を「液状化点」とする。
尚、液状化点とは、水の凝固点(0°/純水、大気圧下)のような定点温度ではなく、ある特定温度に対して略±2℃程度の範囲で定義、数値化される。
(ワックス系潤滑剤の調製)
ジエステル油(ジオクチルセバケート)を78.5質量%、マイクロクリスタリンワックス(融点82℃)を15質量%、添加剤として酸化防止剤及び極圧剤を含む混合物を6.5質量%の割合にて、ワックスの融点以上の温度で混合し、室温まで自然冷却してワックス系潤滑剤を得た。
コーンプレート型粘度計(E型粘度計)を用い、温度を変えて上記ワックス系潤滑剤の粘度を測定した。結果を表1及び図3に示すが、温度の上昇とともに粘度が低下し、流動性が高まることがわかる。具体的には、図4に示すように、42℃までは試料表面の移動はなく、44℃で5mm、46℃で17mmの移動が確認され、48℃で50mmを超えて容器の先端まで達した。そのため、実施例1の組成のワックス系潤滑剤は、47℃の液状化点を有している。即ち、47℃付近で半固体状から液状に変化し始め、一般的な工作機械の主軸支持用の軸受装置の潤滑剤補給システムに利用できることがわかる。
(ワックス系潤滑剤の調製)
ジエステル油(ジオクチルセバケート)を83質量%、マイクロクリスタリンワックス(融点72℃)を10.5質量%、添加剤として酸化防止剤及び極圧剤を含む混合物を6.5質量%の割合にて、ワックスの融点以上の温度で混合し、室温まで自然冷却してワックス系潤滑剤を得た
コーンプレート型粘度計(E型粘度計)を用いて、実施例1と同様にして温度を変えて上記ワックス系潤滑剤の粘度を測定した。結果を図5に示すが、実施例2の組成のワックス系潤滑剤は、温度上昇による粘度変化の割合が38℃を境に減少しており、液状化点は38℃付近である。そのため、20〜40℃程度で使用される軸受装置の潤滑剤補給システムに利用できることがわかる。
本出願は、2014年10月29日出願の日本特許出願(特願2014−220705)に基づくものであり、その内容はここに参照として取り込まれる。
