サイドシール8は、図8に示すように略コ字状をした樹脂製又はゴム製の板部材であって、案内レール2の両側面及び上面に跨嵌する形状をしている。斯かる形状のサイドシール8により、スライダ31を案内レール2上で直線運動させた際に、案内レール2の両側面や上面に付着している塵、埃、ゴミ等の異物を除去することができる。なお、サイドシール8には、スライダ本体4のネジ穴12に対向する位置に、円形の貫通穴9がそれぞれ形成されている。
本実施形態に係るリニアガイド装置用給油装置は、スライダ31内へ潤滑剤を給油するものであり、エンドキャップ5と、潤滑剤容器7と、後述する潤滑部材40とによって構成されている。
エンドキャップ5の方向転換路5aには、図6Aに示すように、スライダ31の長手方向、即ち図6Aの左右方向へ延びる円形の貫通孔16が形成されている、即ち図2Aも参照。
潤滑剤容器7の正面には、図3Aに示すように、4つの凹部18に対向し、かつエンドキャップ5の4つの貫通孔16に対向する位置に、筒状部19がそれぞれ一体的に形成されている。筒状部19は、図6Aに示すように、スライダ31の長手方向内側、即ち図6Aの右方向へ延びており、エンドキャップ5における方向転換路5aの貫通孔16に嵌合する円筒形状をしている。筒状部19内の円形開口、即ち中空部は、対向する凹部18の底面18aを貫通している。
なお、潤滑剤容器7には、スライダ本体4の2つのネジ穴12に対向する位置に、円形の貫通穴20がそれぞれ形成されている。また、潤滑剤容器7の両側の脚部の内側面には、スライダ31内への異物の侵入を防止するために、案内レール2の転動溝2aの形状に合わせて設けられたリップ部7aが備えられている。
潤滑部材40を保持した凹部18は、図3Cに示すように、潤滑剤容器7の背面側より蓋22が取り付けられて密封される。蓋22は、図5に示すように、潤滑剤容器7と同じ樹脂製の板部材からなり、潤滑剤容器7の2つの凹部18を一度に密封するために長方形状をしている。なお、蓋22には、潤滑剤容器7の貫通穴20に対向する位置に円形の貫通穴23が形成されている。
ここで、スライダ本体4の長手方向、即ち図6の左右方向における潤滑剤容器7の筒状部19と潤滑部材40の突起部43の長さは、筒状部19及び突起部43とエンドキャップ5の方向転換路5aの転動溝との間に段差が生じないようにそれぞれ設計されている。そして、潤滑剤容器7の筒状部19の先端面及び潤滑部材40の突起部43の先端面は、図6Bに示すようにエンドキャップ5の方向転換路5aの転動溝に沿った曲面形状にそれぞれ加工されている。
なお、予め潤滑剤容器7は、各凹部18に潤滑部材40を挿入し、背面側より蓋22を取り付けて密封しておく。
この構成により、スライダ31を案内レール2上で直線運動させた際に、方向転換路5aを転動する転動体が潤滑部材40の突起部43の先端面に接触して潤滑剤を塗布されることにより、スライダ31内へ給油することができる。
図10に示す第2実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置102について、上記第1実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。
本実施形態に係るリニアガイド装置用給油装置は、エンドキャップ5と、潤滑剤容器70と、潤滑部材400とによって構成されている。
図13Aに示すように、潤滑剤容器70の凹部18に保持される潤滑部材400は、上記第1実施形態における潤滑剤部材40の突起部43に代えて、スライダ30の長手方向内側、即ち図13Aの右方向へ延在し潤滑剤容器70の円形開口25から外部へ突き出る突起部430が第1潤滑部材410に一体的に形成されている。突起部430は、図13Bに示すように、潤滑剤容器70の円形開口25及びエンドキャップ5の貫通孔16に嵌合する円柱形状をしている。

なお、予め潤滑剤容器70は、各凹部18に潤滑部材400を挿入し、背面側より蓋22を取り付けて密封しておく。
手順1:上記第1実施形態におけるスライダ31の組み立て手順の手順1と同様である。図14Aを参照。
手順3:上記第1実施形態におけるスライダ31の組み立て手順の手順3と同様である。図14Cを参照。
なお、潤滑剤容器7、70及び蓋22はともに樹脂製であるが、これに限られず金属製としてもよい。
図15に示す第3実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置103について、上記第2実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。
本実施形態に係るリニアガイド装置用給油装置は、エンドキャップ5と、潤滑剤容器71と、潤滑部材401とによって構成されている。
また、潤滑剤容器71には、上記第2実施形態における潤滑剤容器70の凹部18に代えて、図17に示すように2つの凹部180が設けられている。凹部180は、上記第2実施形態における潤滑剤容器70の隣接する2つの凹部18をつなげて胴部の中央位置まで延在させた形状、即ちL字型をしている。
なお、潤滑剤容器71には、上記第2実施形態における潤滑剤容器70と同様の円形開口25が同位置に同数設けられている。
斯かる構成の潤滑部材401を保持した凹部180は、図16Cに示すように、潤滑剤容器71の背面側より蓋220が取り付けられて密封される。なお、本実施形態における蓋220は、潤滑剤容器71の凹部180に合わせてL字型をしている。
なお、予め潤滑剤容器71は、各凹部180に潤滑部材401を挿入し、背面側より蓋220を取り付けて密封しておく。
手順1:上記第2実施形態におけるスライダ32の組み立て手順の手順1と同様である。図18Aを参照。
手順3:上記第2実施形態におけるスライダ32の組み立て手順の手順3と同様である。図18Cを参照。
図19に示す第4実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置104について、上記第3実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。
本実施形態に係るリニアガイド装置用給油装置は、エンドキャップ50と、潤滑剤容器72と、潤滑部材402とによって構成されている。
詳細には、本実施形態におけるエンドキャップ50は、エンドキャップ50の4つの方向転換路5aのうち、スライダ本体4側から見て対角線上に位置する2つの方向転換路5aに貫通孔16が備えられている。
図24に示す第5実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置105について、上記第3実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。
本実施形態に係るリニアガイド装置用給油装置は、エンドキャップ5と、潤滑剤容器73と、潤滑部材401とによって構成されている。
なお、予め潤滑剤容器73は、各凹部180に潤滑部材401を挿入し、背面側より蓋220を取り付けて密封しておく。
手順1:上記第3実施形態におけるスライダ33の組み立て手順の手順1と同様である。図28Aを参照。
手順3:上記第3実施形態におけるスライダ33の組み立て手順の手順3と同様である。図28Cを参照。
また、以上の組み立て手順に基づいて組み立てたスライダ35は、上記第3実施形態と同様の効果を奏することができる。特に、本実施形態では、潤滑剤容器73の各円形凹部73aに嵌め込まれたOリング45により、各円形開口25を取り囲むように、潤滑剤容器73とエンドキャップ5との間を密閉することができる。このため、潤滑剤が潤滑剤容器73とエンドキャップ5の間からスライダ35外へ漏洩することを防止できる。したがって、スライダ35の周辺が潤滑剤で汚染されることを防止できるとともに、潤滑剤を不必要に消費することも防止できる。
図29に示す第6実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置106について、上記第3実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。
本実施形態に係るリニアガイド装置用給油装置は、エンドキャップ5と、潤滑剤容器74と、潤滑部材401とによって構成されている。
ポリオレフィンは比重が1以下で軽量である。したがって、潤滑部材40、400~402をポリオレフィンで構成することにより、潤滑部材40、400~402から潤滑剤容器7、70~74へかかる負荷が小さくなるため、潤滑剤容器7、70~74に対して有効である。
また、ポリオレフィンは絶縁性が高い。したがって、スライダ31~36が案内レール2上を走行した時にエンドキャップ5、50の方向転換路5aと転動体との摩擦により静電気が生じた場合でも、ポリオレフィンで構成した潤滑部材40、400~402で絶縁することができる。このため、静電気によって潤滑剤容器7、70~74が破損してしまうことを防止することができる。
また、図6Bに示したように潤滑剤容器7の筒状部19と潤滑部材40の突起部43とを嵌合させる構成の場合、軟質であるPEを潤滑部材40の材料に用いることで、筒状部19に突起部43を嵌めやすくなるので好ましい。なお、PEに剛性をもたせるために、PEにPPをコンパウンドすることがより好ましい。
図32に示す第7実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置107について、上記第1実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。

また、本実施形態では潤滑剤容器7の凹部18に潤滑部材151と押さえ部品51が挿入された後、潤滑剤49が隙間なく充填される。しかしこれに限られず、潤滑剤49の代わりに潤滑剤を含浸した多孔質成形体や潤滑剤を含浸した多孔質弾性体を凹部18に隙間なく配置する構成としてもよい。なおこのことは、後述する第8実施形態においても同様である。
図37に示す第8実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置108について、上記第2、第7実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。

図41に示す第9実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置109について、上記第1実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。
本実施形態に係るリニアガイド装置用給油装置は、図42に示すように、エンドキャップ5と、潤滑剤容器56と、潤滑部材153とによって構成されている。
潤滑剤容器56は、図42に示すように、上記第1実施形態における潤滑剤容器7の筒状部19内の中空部を、潤滑部材153の突起部213が嵌合できるようにテーパー形状にしたものである。
また、本実施形態における潤滑部材153は、上記第2実施形態のリニアガイド装置102に適用することもできる。図44を参照。この場合、第2実施形態における潤滑剤容器70の円形開口25及びエンドキャップ5の貫通孔16を潤滑部材153の突起部213が嵌合できるようにテーパー形状とする。
図45に示す第10実施形態に係るリニアガイド装置用給油装置を備えたリニアガイド装置110について、上記第2実施形態と同様の構成については同じ符号を付して説明を省略し、異なる構成について詳細に説明する。
本実施形態に係るリニアガイド装置用給油装置は、図46に示すように、エンドキャップ54と、潤滑剤容器57と、潤滑部材154とによって構成されている。
なお、潤滑部材154の長さは、後述するように潤滑部材154にOリング58を装着してエンドキャップ54の貫通孔164に挿入した際に、潤滑部材154とエンドキャップ54の方向転換路5aの転動溝との間に段差が生じないように設計されている。具体的には、潤滑部材154の長さは、エンドキャップ54の貫通孔164の長さよりもOリング58の厚み分だけ大きく設計されている。
なお、予め潤滑剤容器57は、各凹部18に潤滑剤49を充填し、背面側より蓋22を取り付けておく。
手順1:図49Aに示すように、樹脂製で断面が円形のOリング58に潤滑部材154を挿入する。そして、潤滑部材154の上述した曲面形状に加工された先端面と反対側の端部にOリング58を配置する。
手順3:上記第2実施形態におけるスライダ32の組み立て手順の手順1と同様である。図50Aを参照。
手順5:上記第2実施形態におけるスライダ32の組み立て手順の手順3と同様である。図50Cを参照。
