Abstract
Description
特許文献1のサイドシールは(この特許文献1ではエンドシールと称している)、レール外面と隙間を設けて対向して配置されるスクレーパー部と、スライダの移動方向の端面とスクレーパー部との間に配置され、レール外面との間に隙間を設けて対向して配置されるケース部と、ケース部及びスクレーパー部の間でシール基部が挟持され、シール基部から延在したリップがレール外面に接触するシール部材とを備えた構造としている。
また、特許文献2のサイドシールは、エンドキャップに形成した凹溝に、サイドシールのシール外周が嵌合により装着されているだけであり、大きな振動が加わると凹溝からシール基部が抜け出て、シール部材が脱落してしまうおそれがある。
また、本発明の一の実施形態に係るリニアガイド装置は、前記基部収容凹部の前記断面方向位置合せ部が、前記案内面に向けて突出する突起である。
さらに、本発明の一の実施形態に係るリニアガイド装置は、前記シール部材及び前記カバー部材が、前記厚み方向の移動が規制されて着脱自在に一体化されている。
さらにまた、本発明の一の実施形態に係るリニアガイド装置は、前記保持板及び前記カバー部材が、厚み方向の移動が規制されて着脱自在に一体化されている。
図1に示すリニアガイド装置1は、案内レール2、スライダ5、エンドキャップ10及び、サイドシール12を備えた装置である。
案内レール2は、合金鋼等の鋼材で製作された長尺の棒状部材であり、レール上面2aには機械装置の基台等に案内レール2を固定するための段付ボルト孔であるレール設置孔3が所定のピッチで複数設けられている。案内レール2の側面には、案内レール2の長手方向に沿って略V字状に形成された一対のレール軌道面4が形成されている。
スライダ5は、合金鋼等の鋼材で製作された略コの字状の断面形状を有する鞍状部材であり、上面には取付けねじ穴5aが設けられており、この取付けねじ穴5aを用いて機械装置の移動台等がボルト等により締結されるようになっている。
エンドキャップ10のスライダ5側の端面には、潤滑剤供給溝(不図示)に接続するグリースニップル14が取付けられており、このグリースニップル14は、エンドキャップ10の方向転換路11に潤滑剤としてのグリースを補充するときに用いられる。
サイドシール12は、図3に示すように、保持板16と、シール部材17と、カバー部材18とで構成されている。これらの部材は、シール部材17を間に挟んで保持板16及びカバー部材18を重ね合わせ(図4参照)、エンドキャップ10の外側の端面に保持板16を当接し、保持板16及びカバー部材18の互いに対応したねじ穴16a,18aに挿通したねじ部材19(図1参照)をエンドキャップ10の端面にねじ込むことで装着される。なお、図3の保持板16の符号16bで示す部位、カバー部材18の符号18bで示す部位は、グリースニップル14が挿通するニップル挿通穴である。
保持板16は、図5に示すように、スライダ5と同様に略コの字形状を有する鞍状部材であり、ポリアセタール樹脂、66ナイロン樹脂などの硬質合成樹脂の射出成形品、アルミニウム、鋼材などの金属材料で形成されている。
保持板16の内周部16eは、案内レール2のレール上面2a及び側面(一対のレール軌道面4)に対向する形状に形成されており、カバー部材18が当接する一方の面16cには、シール部材17を保持する帯状の基部収容部20及び係合溝21が内周部16eに沿って形成されている。なお、保持板16の他方の面16dは、エンドキャップ10の外側の端面に当接する。
また、断面方向位置合せ面20bからランド部22が連続して形成されており、このランド部22は、厚み方向位置合せ面20aより一方の面16c側に突出して形成されている。
係合溝21は、基部収容部20に対して内周部16eから離間する位置に設けられており、ランド部22より深い凹形状の溝として形成されている。
シール部材17は、図8に示すように、略コの字形状に曲がった帯状部材であり、その内周輪郭は、案内レール2のレール上面2a及び一対のレール軌道面4の輪郭に対して、後述するしめしろ分だけ縮小した形状とされている。このシール部材17は、可撓性の高い合成樹脂またはゴムの射出成形品からなり、具体的な材料としては、ポリエステル系エラストマー樹脂、ウレタン系エラストマー樹脂、ニトリルゴム樹脂,ふっ素ゴム樹脂などの部材である。ポリエステル系エラストマー樹脂の具体的な商品名としては、東洋紡社製のペルプレンEN1000,EN2000,EN3000,EN5000などがある。
図10の符号Lで示す線は、レール上面2a及び一対のレール軌道面4の位置を示す仮想線であり、リップ26は図10の上方向に弾性変形する。リップ26の厚さが薄すぎるとリップの強度が不足する。逆にリップ26の厚さが厚すぎると可撓性が不足するので、本実施形態では、リップ厚さh=0.5mmとしている。
また、仮想線Lからのリップ26の先端の突出量Sが前述したしめしろ分である.このしめしろ分は、製作誤差があってもレール上面2a及び一対のレール軌道面4との間に隙間が生じないように定めた。本実施形態では、S=0.15mmとした。
シール部材17のシール基部25は、図10に示すように、保持板16の基部収容部20に形成した厚み方向位置合せ面20aに当接する厚み方向被位置合せ部25aと、断面方向位置合せ面20bに当接する断面方向被位置合せ部25bと、カバー部材18に当接するカバー部材当接部25cとを備えている。
シール部材17の第1延長部27は、図6で示した保持板16のランド部22に沿って延在し、シール部材17の第1係止部28は、保持板16の係合溝21に入り込むようになっている。
すなわち、図11に示すように(図9のD-D線矢視図)、シール部材17の第1係止部28の一部から連続してリップ26から離間する断面方向に第2延長部29が形成されて、第2延長部29の端部に第2係止部30が形成されている。この第2係止部30の端部には、爪部30aが形成されている。
また、図9の符号Uの丸印を拡大して示した図12のように、シール部材17のリップ26の一部には、内側に突出するリップ突起部26bが形成されている。このリップ突起部26bは、前述したレール上面2aに設けたレールカバー9の幅方向縁部により形成された段差部15に対応する。
図13のE-E線矢視で示す部分は、保持板16を説明した図5において太線の符号Bで示した(厚み方向位置合せ面20a及び断面方向位置合せ面20bを備えた基部収容部20が形成されている)位置である。
また、図13のF-F線矢視を示す部分は、保持板16を説明した図5において太線の符号Bで示していない(厚み方向位置合せ面20aのみを備えた基部収容部20が形成されている)位置である。
この厚み方向位置合せ面20a及び断面方向位置合せ面20bを備えた基部収容部20では、図16に示すように(図13のG-G線矢視図)、シール部材17のシール基部25が圧縮され、厚み方向位置合せ面20aに厚み方向被位置合せ部25aが当接する。また、シール部材17のリップ26が案内レール2の一対のレール軌道面4に接触し、シール基部25が図16の右方の断面方向に押圧されることで、断面方向位置合せ面20bに断面方向被位置合せ部25bが当接する。
さらに、第1係止部28から連続する第2延長部29は延長溝23に沿って延在し、第2係止部30は、保持板16係合穴24に入り込み、係合穴24の他方の面16d側で開口する縁部に形成した係合段差部24aに、第2係止部30の端部に形成した爪部30aが係合する。
図17は、本実施形態に対する比較例を示すものである。この比較例では、保持板16の基部収容部20は、シール部材17のシール基部25の厚み方向被位置合せ部25aに当接する厚み方向位置合せ面を設けておらず隙間を設けている。また、シール部材17の第1係止部28が、保持板16の係止溝21に厚み方向から接触している構造である。
これに対して、本実施形態のサイドシール12は、図14から図16で示したように、シール部材17の圧縮変形したシール基部25が、保持板16の基部収容部20の厚み方向位置合せ面20aに当接し、サイドシール12がスライダ5とともに移動して厚み方向の外力が作用しても、厚み方向位置合せ面20aが外力を受止めてリップ26の変形を確実に防止する。これにより、防塵性能は低下せず、リップ26の根本の破損等を防止することができる。
さらに、図12で示したように、サイドシール12がスライダ5とともに移動する際には、シール部材17のリップ26の一部に形成したリップ突起部26bが、レール上面2aに設けたレールカバー9の幅方向縁部の段差部15に接触する構造としているので、段差部15の防塵を確実に行なうことができる。
次に、図18及び図19は、シール部材の変形例を示すものである。
本実施形態のシール部材31が、図8から図12で示したシール部材17と異なる構造は、符号32a,32bで示す部位の断面形状が、図19に示すように、シール基部25及びリップ26とからなる形状であり、第1延長部27及び第1係止部28を備えていない形状としている。
本実施形態のシール部材31によると、第1延長部27及び第1係止部28を備えていない形状とすることでリップ26の大きさを小さくすることができ、サイドシール12の周辺のスペースが制限される場合に有効である。
次に、図20及び図21は、シール部材の変形例及びこのシール部材を使用したサイドシールの構造を示すものである。
本実施形態のシール部材32が、図8で示したシール部材17と異なる構造は、第2延長部29の端部に形成した第2係止部30が突出する方向に対して逆側の位置に、第3係合部33が形成されている。
この第3係合部33は、互いが近づく方向に弾性変形可能な一対の弾性片33a,33bで構成されている。
さらに、図22及び図23は、保持板の変形例を示すものである。
本実施形態の保持板34は、図5から図7で示した保持板16の基部収容部20に断面方向位置合せ面20bを設けず、代わりに、案内レール2のレール上面2a及び一対のレール軌道面4に向けて突出する突起35が長手方向(帯状が延在する方向)に所定間隔をあけて多数形成されている。この突起35の突出量は、0.05~0.10mm程度である。
また、上記実施形態のリニアガイド装置1は、レール上面2aにレールカバー9が設けられているが、レール上面2aにレールカバー9を設けていない装置にも適用できる。
さらにまた、図24から図26は、図3で示した構成と異なるサイドシールを示すものである。なお、図3から図16で示したサイドシール12と同一構成部分には、同一符号を付してその説明は省略する。
本実施形態のサイドシール36は、図24に示すように、保持板37と、シール部材38と、保持板37と略同一形状(略コの字形状を有する鞍状)のカバー部材39とで構成されている。
さらに、本実施形態のカバー部材39は、保持板37の一対の第4係合部40の爪部40aにそれぞれ係合する一対の係合凹部39aが形成されていることが、図3のカバー部材18と異なっている(図26(a)参照)。
ここで、保持板37及びカバー部材39は、図26(b)に示すように、係合凹部39aの周縁及び第4係合部40の爪部40aの間に厚さ方向の所定の隙間T1と、係合凹部39aの内壁及び第4係合部40の間に断面方向の所定の隙間T2とを設けた状態で一体化、即ち、厚さ方向及び断面方向にガタ付きを設けた状態で一体化されている。
また、カバー部材39は、厚さ方向及び断面方向にガタ付きを設けて保持板37に一体化されており、カバー部材39が多少反っていても正常に保持板37に一体化することができるので、カバー部材39の製造コストの低減化を図ることができる。
さらに、本実施形態のシール部材38は、略コの字形状に曲がった部分から外側に突出する第2延長部29(図8参照)が形成されておらず簡便な構造となるので、シール部材38の製造コストの低減化も図ることができる。
