- the occlusion body 16 is made of a low-density porous molded body as compared with the application body 17, the storage amount of the lubricant per unit volume is large and the volume is also large. The agent can be stored in large quantities.
- the application body 17 is a thin plate-like member as compared with the occlusion body 16 and the contact area with the guide rail 2 is small, an appropriate amount of lubricant is applied while preventing the lubricant from flowing out to the guide rail 2. It can be applied to the guide rail 2. Therefore, a large amount of lubricant can be prevented from being consumed in a short period of time, and refueling can be performed stably for a long period of time.

- the lubricant in the occlusion body 16 can be smoothly and stably guided to the application body 17 by providing the small diameter portion 21 a in the communication hole 21.
- the lubricant has a capillarity phenomenon, that is, an intermolecular force (cohesive force) acting on the lubricant molecule, between the small diameter portion 21 a of the communication hole 21 and the lubricant molecule. Since the working force (adhesion force, easiness to wet) is larger, it can be guided smoothly and stably to the application body 17 by being drawn into the wall surface of the small diameter portion 21a and entering the small diameter portion 21a. Therefore, it is possible to provide an oil supply device that can sufficiently apply the lubricant to the guide rail and a linear motion guide device including the oil supply device.

以下の詳細な説明では、本発明の実施形態の完全な理解を提供するように多くの特定の細部について記載される。しかしながら、かかる特定の細部がなくても1つ以上の実施態様が実施できることは明らかであろう。他にも、図面を簡潔にするために、周知の構造及び装置が略図で示されている。
<直動案内装置>
図1(a),(b)に示すように、本実施形態の直動案内装置(リニアガイド装置)1は、案内レール2と、図示しない転動体と、この転動体を介して案内レール2の長手方向に沿って移動可能なスライダ3とを有する。本実施形態の直動案内装置1は、例えば、数値制御工作機や数値制御測定機等に好適なものである。
スライダ3は、スライダ本体4と、スライダ本体4の長手方向(図1(b)の左右方向)の両端部に、スライダ本体4側から順に取り付けられたエンドキャップ5、給油装置7、及びサイドシール8とからなる。以下、本実施形態においては、案内レール2の長手方向をスライダ3(スライダ本体4)の移動方向とし、その移動方向に直交する方向のうち、案内レール2を基準として案内レール2が跨架される方向を「上下方向」、案内レール2の両側面を結ぶ方向を「幅方向」ということがある。また、エンドキャップ5、給油装置7、及びサイドシール8においては、スライダ本体4に対向する側の面を「正面」、上記移動方向を基準としたその反対側の面を「背面」とする。
図1(a),(b)及び図2に示すように、スライダ本体4は、案内レール2の長手方向へ延在し、断面が略U字状をした金属製部材からなり、案内レール2に跨架されている。また、図2(b)に示すように、スライダ本体4において案内レール2の両側面に対向する脚部4A,4Aのそれぞれの内側面には、案内レール2の転動面2aと対向して長手方向へ延びる転動面4aが2条ずつ形成されている。
また、図2(b)に示すように、スライダ本体4の脚部4A,4Aには、スライダ本体4の長手方向へ貫通する戻し路4bが2本ずつ形成されている。また、スライダ本体4の両端面にはネジ穴11,12が2箇所ずつ形成されている。
図3に示すように、エンドキャップ5は、スライダ本体4の断面とほぼ同様のU字形状の断面形状をなしている。スライダ本体4に対向するエンドキャップ5の正面には、上記転動路と戻し路4bとを接続する方向転換路5aが両側の脚部4A,4Aに2箇所ずつ形成されている。
また、エンドキャップ5には、スライダ本体4のネジ穴11,12に対向する位置に、円形の貫通穴13,14がそれぞれ形成されている。なお、エンドキャップ5の材料は、その機能を損なわなければ、樹脂製でも金属製でもよく、目的に応じて適宜選択される。
図4に示すように、サイドシール8は、スライダ本体4やエンドキャップ5のそれぞれの断面形状とほぼ同様に、案内レール2の両側面及び上面に跨架するU字形状の断面をなす。サイドシール8がこのような形状をなしていることにより、スライダ3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。なお、サイドシール8は、例えば樹脂製であることが好ましい。
次に、給油装置の第1実施形態について図面を参照して説明する。本実施形態の給油装置は、上述した直動案内装置に備えられることが好ましい。そのため、本実施形態の説明では、一例として直動案内装置1に備えられた給油装置7として説明する。
ここで、潤滑剤には、鉱油、合成油+合成炭化水素油、鉱油+合成炭化水素油、合成炭化水素油等の潤滑油(粘度10~200mm2/δ)や、リチウム系、ジウレア系、ウレア結合物等のグリース(ちょう度130~295)を用いることが好ましい。
塗布体17は、案内レール2の両側面及び上面に接触して潤滑剤を塗布するものである。塗布体17は、図7に示すように、吸蔵体16よりも小さな略U字状をした薄い板状部材であり、吸蔵体16よりも高密度な樹脂製の多孔質成形体からなる。塗布体17の内側面は、案内レール2の両側面及び上面に接触可能なように、案内レール2の外形に沿った形状をしている。より詳細には、塗布体17の内側面には、案内レール2の両側面の転動面2aに接触可能なリップ部17aが設けられている。また、塗布体17の両側の脚部先端の内側面には、矩形の切り欠き部17bが形成されている。
ここで、吸蔵体16及び塗布体17に用いられる多孔質成形体としては、フェルト、樹脂、熱可塑性エラストマーが挙げられる。
上記フェルトの材料としては、ポリプロピレン、ポリエチレン、ポリエチレンテレフタレート、ポリブチレン、ポリメチルペンテン等のポリα-オレフィン系の繊維等が挙げられる。その他に、ポリアラミド等のアラミド繊維、PTFE等のフッ素系繊維等が挙げられる。
上記樹脂材料としては、ポリプロピレン、ポリエチレン、ポリエチレンテレフタレート、ポリブチレン、ポリメチルペンテン等のポリα-オレフィン系の樹脂、EVA樹脂、EVOH樹脂等が挙げられる。
上記熱可塑性エラストマーとしては、ポリアミド等のポリアラミド系のエラストマー、ポリエチレン、ポリプロピレン等のエラストマー等が挙げられる。
また、吸蔵体16又は塗布体17と、潤滑剤との割合(質量%)は、10~80:90~20が好ましい。吸蔵体16又は塗布体17の割合が10質量%未満だと強度不足となり、80質量%を超えると、潤滑剤の含有量が少なくなるため、潤滑剤供給不足となる。なお、吸蔵体16、塗布体17の材料、潤滑剤の組合せは、限定されるものではない。
図8(a)~(c)に示すように、容器18は、エンドキャップ5と略同じく略U字状の断面形状をした樹脂製の厚板部材である。図8(a)に示すように、容器18の背面(スライダ3の長手方向外側の面)には、吸蔵体16を収納する吸蔵体収納部22と、塗布体17を収納する塗布体収納部23が仕切り部19を介して設けられている。なお、容器18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27が形成されている。
吸蔵体収納部22は、図8(a)に示すように、容器18の外周面側の形状に沿って略U字状をなす底の深い(移動方向に沿う方向の寸法が長い)凹部からなり、その内部に吸蔵体16を隙間なく嵌合することができる。吸蔵体収納部22は、塗布体収納部23よりも底が深く、塗布体収納部23を包囲するように容器18に設けられているので、塗布体収納部23よりも容積が大きい。
塗布体収納部23は、図8(a)に示すように、容器18の内周面側の形状に沿って略U字状をした底の浅い(移動方向に沿う方向の寸法が短い)凹部からなり、その内部に塗布体17を隙間なく嵌合することができる。塗布体収納部23は、案内レール2に対向する部分が開放されており、塗布体17を収納した際に該塗布体17が案内レール2に接触することが可能である。
図8(a)に示すように、塗布体収納部23の外側には塗布体収納部23の外形に沿って吸蔵体収納部22が形成されている。そして、吸蔵体収納部22と塗布体収納部23との境界を画成する壁として、塗布体収納部23と吸蔵体収納部22とを仕切る仕切り部19が容器18に設けられている。仕切り部19は、容器18の背面側から見てU字状をなしている。さらに、仕切り部19は、塗布体収納部23の両側の脚部の下端へ延在しさらに内側面まで延在しており、L字状の壁部28を形成している。
連通穴21は、図8(c)に示すように、塗布体収納部23側に設けられた小径部21aと、吸蔵体収納部22側に設けられ、小径部21aと同芯で径の大きな大径部21bとを有する。なお、連通穴21の断面形状は、円形に限られず矩形等でもよい。
次に、給油装置7の組み立ての手順について図5を参照して説明する。
まず、図5(a)に示すように、容器18の塗布体収納部23に塗布体17を収納する。このとき、塗布体17の切り欠き部17bと容器18のL字状の壁部28が嵌り合う。これにより、L字状の壁部28は塗布体17をスライダ本体4の上下方向において位置決めしつつ支持することができる。
次に、スライダ本体4への給油装置7の取り付けの手順について図5、図10、及び図11を参照して説明する。
このようにして、給油装置7を直動案内装置1に容易に取り付けることができる。
給油装置7を備えた直動案内装置1は、吸蔵体収納部22内の吸蔵体16に貯蔵されている潤滑剤が、仕切り部19に設けられた連通穴21から塗布体収納部23へ導かれ、塗布体収納部23内の塗布体17に供給される。これにより、塗布体17は、スライダ3が案内レール2上で移動(直線運動)した際に、案内レール2の両側面及び上面に接触して潤滑剤を塗布することができ、給油が達成される。
よって、潤滑剤を案内レールに十分に塗布することが可能な給油装置及びそれを備えた直動案内装置を提供することができる。
本実施形態の給油装置は、内部に後述する押圧部材を設けた以外は上述した第1実施形態と異なるだけであるため、第1実施形態と重複又は相当する部材等については図に同一符号を付して説明を省略する。この給油装置を備えた直動案内装置の第2実施形態についても、第1実施形態の直動案内装置と給油装置以外の構成は同様であるので説明を省略する。
押圧部材37は、金属製で断面が例えば、円形の棒状部材からなる。そして、押圧部材37は、容器18の吸蔵体収納部22の上面22a及び側面22b,22bに内接するW字形状をなすと共に、中央部分で下方に湾曲する部分が仕切り部19に形成した連通穴21の縁部に付勢するように設置されている。なお、押圧部材37は、吸蔵体16と塗布体17とをより確実に接触させるために、吸蔵体16を連通穴21に押すように吸蔵体収納部22内に設置されれば、このような形状や設置態様でなくともよく、目的に応じて適宜選択される。また、押圧部材37の断面は円形に限られず、矩形等でもよい。
押圧部材37の具体的な材料としては、例えば、硬鋼線、ピアノ線、オイルテンパー線、ステンレス鋼線、ばね鋼鋼材等が挙げられる。
次に、給油装置7の組み立ての手順について図12を参照して説明する。なお、「給油装置の取り付け」については、第1実施形態と同様なので説明を省略する。
まず、図12(a),(b)に示すように、容器18の塗布体収納部3に塗布体17を収納する。このとき、塗布体17の切り欠き部17bと容器18のL字状の壁部28が嵌り合う。これにより、L字状の壁部28は塗布体17をスライダ本体4の上下方向において位置決めしつつ支持することができる。
ここで、潤滑剤は、吸蔵体16から塗布体17の方へ放出されるので、吸蔵体16の内部の潤滑剤は減少する。それによって毛細管現象は弱まり、塗布体17への潤滑剤の供給量は減少し、直動案内装置は潤滑不良になってしまう。
そこで、押圧部材37を設置することで、連通穴21内に押し込まれた吸蔵体16が塗布体収納部23内へ突出して塗布体17を変形させるとともに塗布体17に確実に接触する。なお、この状態は押圧部材37の中央部の湾曲部分の付勢力によって維持される。このように、押圧部材37の圧縮力により、毛細管現象による塗布体への潤滑剤供給量を増やすことができる。
なお、変形例として、連通穴21が小径部21aと大径部21bとからなるのではなく、図12(d)に示すように、幅が一様の連通穴21Cで構成され、この連通穴21Cの縁部に押圧部材37の中央部の湾曲部分が付勢するように設置されてもよい。
このようにして給油装置7の組み立てが完了する。なお、容器18に対する蓋33の取り付けは、必要に応じて接着剤を用いてもよい。
