Abstract
Description
図1および図2に示されるように、ロボット10は、ベース11、第1アーム12、第2アーム13およびボールねじスプライン(BS)シャフト14を備える水平多関節ロボットである。
第1アーム12の一端部は、鉛直な第1軸線J1回りに回転可能にベース11に支持され、第1アーム12は、ベース11に対して水平方向に回転可能である。
第2アーム13の一端部は、鉛直な第2軸線J2回りに回転可能に第1アーム12の他端部に支持され、第2アーム13は、第1アーム12に対して水平方向に回転可能である。
例えば、第1部材51は、円筒状の部材であり、第1部材51を周方向に分断するスリットを有する。第1部材51は、スリットを横切るボルト7aを締め付けることによって、BSシャフト14の上端部の外周面に固定されている。第1部材51および第2部材52は、第1部材51および第2部材52に長手方向に挿入されたボルト7bによって相互に固定されている。
カバー部材4の上端部は延長シャフト2の上端部に固定されている。具体的には、延長シャフト2の上端部には円環板状のフランジ部2aが設けられ、カバー部材4の上端部には円環板状のフランジ部4aが設けられている。フランジ部2aはフランジ部4aの上に配置され、フランジ部2aおよびフランジ部4aがボルト7cによって相互に固定されている。
シール(第1の固定シール)81は、延長シャフト2の上端部とカバー部材4の上端部との間を封止し、防水構造1の外側から空間Sへ液体が侵入することを阻止するものである。
具体的には、シール81は、フランジ部2aの下面とフランジ部4aの上面との間に配置されている。フランジ部2aおよびフランジ部4aは相互に静止した固定部分であるので、シール81として、ガスケット等の固定シールが使用される。
具体的には、第2部材52の下端面には、第1部材51の内部に嵌合する円環状の凸部52cが設けられ、凸部52cの下端面とBSシャフト14の上端面とが相互に対向している。シール82は、凸部52cの下端面とBSシャフト14の上端面との間に配置されている。BSシャフト14およびベアリングホルダ5は相互に静止した固定部分であるので、シール82として、Oリング等の固定シールが使用される。
具体的には、第2部材52の内面は、延長シャフト2の円環状の下端面と対向する円環状の下壁52aと、下壁52aの外縁から上方に立ち上がる円筒状の側壁52bとを有する。延長シャフト2の下端面と下壁52aとの間に水平方向の円環状の隙間9aが設けられ、延長シャフト2の外周面と側壁52bとの間に鉛直方向の円筒状の隙間9bが設けられている。
ロボット10の作動時、第2アーム13内のモータ(図示略)からBSシャフト14に回転力が伝達されることによって、BSシャフト14は、第3軸線J3回りに回転しながら第3軸線J3に沿って上昇および下降する。BSシャフト14と共に延長シャフト2も上昇および下降する。カバー部材4は、延長シャフト2の上端部の上昇および下降によって伸縮変形する。このようなカバー部材4によって、外部から第2アーム13の内部へ液体が侵入することが阻止される。
また、ベアリング6をラビリンスシール9の上側に配置することによって、ベアリング6への液体の侵入を確実に防止し、回転部分の高い防水性能を安価な構成で実現することができる。
例えば、固定部2bは、延長シャフト2の上端面に開口するタップ穴であり、固定部材15が、タップ穴2b内にボルト7dを締結することによって延長シャフト2の上端面に固定される。線条体16は、シャフト2,14内を通って延長シャフト2の上端面から引き出され、固定部材15によって延長シャフト2の上端部に対して固定される。
延長シャフト2は第3軸線J3回りに回転しないので、線条体16のねじれを防止しながら線条体16を延長シャフト2に対して固定することができる。
