Description
このようなリニアガイド装置のサイドシールの従来例としては、金属製の保持板にゴム製のシール部材の基部が固定され、シール部材のリップ部を案内レールの上面および両側面に接触させて使用するものが挙げられる。
この発明の課題は、リニアガイド装置用サイドシールとして、密封性能と防塵性能の両方に優れるとともに、シール摩擦力が低減されたものを提供することである。
前記第1態様のリニアガイド装置用サイドシールによれば、前記2個のシール部材のリップ部の傾きが互いに離れる反対向き(それぞれに隣接するカバー側の向き)であるため、密封性能と防塵性能の両方に優れる。また、前記2個のシール部材の材質が異なるため、各シール部材の材質を適切に選択することで、シール摩擦力を低減することができる。
前記第1態様のリニアガイド装置用サイドシールは、前記2個のシール部材の案内レールの面に対するリップ部の締め代を異なるものとすることで、密封性能と防塵性能の両方に優れるとともに、シール摩擦力が低減されたものにすることができる。
この実施形態のサイドシールは、図11のリニアガイド装置用サイドシールであって、図1に示すように、2個のシール部材1A,1Bと、保持板2と、2枚のカバー3とで構成されている。
2個のシール部材1A,1Bは、図2に示すように、正面から見た配置で、案内レールの上側に配置される上側シール部1aと、案内レールの左右各側に配置される側方シール部1bとに分けられる。各シール部材1A,1Bは、また、図2および図3に示すように、各シール部1a,1bが案内レールと向かい合う方向で、案内レールの上面および両側面に接触させるリップ部11a,11bと、保持板2に保持される基部12とに分けられる。
シール部材1A,1Bのリップ部11a,11bは、基部12の先端部12bに形成され、基部12の厚さ方向の第1の面13側から第2の面14側に傾斜している。シール部材1の最も外側(案内レールから離れる側)の面である第3の面15は、基端部12cの第1および第2の面13,14と直交する。
図9のサイドシール203は、第1のシール部材1Aのリップ部11aと第2のシール部材1Bのリップ部11bの両方を面接触形状として、第1のシール部材1Aの厚さを第2のシール部材1Bの厚さより厚くしている。また、図9の例でも、第1のシール部材1Aを、ヤング率が50~300N/mm2(好適には100~200N/mm2)の撓み難い弾性体(例えば、熱可塑性エラストマー)からなるものとし、第2のシール部材1Bを、ヤング率が3~50N/mm2(好適には5~20N/mm2)の撓み易い弾性体(例えば、ニトリルゴム、フッ素ゴム)からなるものとしている。これによっても、密封性能と防塵性能の両方に優れるとともに、シール摩擦力が低減されたサイドシールが得られる。
