Description

本発明は、例えば工作機械や搬送装置等に用いられる直動案内軸受装置に関する。   The present invention relates to a linear motion guide bearing device used for, for example, a machine tool, a conveying device, and the like.

従来の直動案内軸受装置としては、例えば図４に示すものが知られている。
この直動案内軸受装置は、軸方向に延びる案内レール１と、該案内レール１上に軸方向に相対移動可能に跨架されたスライダ２とを備える。
案内レール１の両側面にはそれぞれ軸方向に延びる転動体転動溝３が形成されており、スライダ２のスライダ本体２Ａには、その両袖部４の内側面に、それぞれ転動体転動溝３に対向する転動体転動溝７が形成されている。そして、これらの向き合った両転動体転動溝３，７の間には転動体の一例としての多数のボールＢが転動自在に装填され、これらのボールＢの転動を介してスライダ２が案内レール１上を軸方向に沿って相対移動できるようになっている。 As a conventional linear motion guide bearing device, for example, the one shown in FIG. 4 is known.
This linear motion guide bearing device includes a guide rail 1 extending in the axial direction, and a slider 2 straddling the guide rail 1 so as to be relatively movable in the axial direction.
Roller element rolling grooves 3 extending in the axial direction are formed on both side surfaces of the guide rail 1. The slider body 2 A of the slider 2 has rolling element rolling grooves on the inner side surfaces of both sleeve portions 4. 3 is formed with a rolling element rolling groove 7 opposite to the rolling element 7. A large number of balls B as an example of rolling elements are slidably loaded between the rolling grooves 3 and 7 facing each other, and the slider 2 is moved through the rolling of these balls B. It can move relative to the guide rail 1 along the axial direction.

この移動につれて、案内レール１とスライダ２との間に介在するボールＢは転動してスライダ２の端部に移動するが、スライダ２を軸方向に継続して移動させていくためには、これらのボールＢを無限に循環させる必要がある。
このため、スライダ本体２Ａの袖部４内に軸方向に貫通する転動体通路８を形成すると共に、スライダ本体２Ａの両端にそれぞれ略コ字状のエンドキャップ５を例えばねじ１２等の固定手段を介して固定し、このエンドキャップ５に上記両転動体転動溝３，７間と上記転動体通路８とを連通する半円弧状に湾曲した方向転換路６を形成することにより、転動体無限循環軌道を形成している。なお、図４において、符号１１はエンドキャップ５と共にスライダ本体２Ａの端面にねじ１２等を介して固定されたサイドシール、１０はスライダ本体２Ａの端面に形成されたねじ１２のタップ穴、１３は給脂用ニップル、１４は案内レール１の固定用のボルト挿通穴である。 Along with this movement, the ball B interposed between the guide rail 1 and the slider 2 rolls and moves to the end of the slider 2, but in order to continuously move the slider 2 in the axial direction, It is necessary to circulate these balls B indefinitely.
For this reason, a rolling element passage 8 penetrating in the axial direction is formed in the sleeve portion 4 of the slider body 2A, and substantially U-shaped end caps 5 are respectively attached to both ends of the slider body 2A. The end cap 5 is formed with a direction change path 6 curved in a semicircular arc shape that communicates between the rolling element rolling grooves 3 and 7 and the rolling element passage 8. A circular orbit is formed. In FIG. 4, reference numeral 11 denotes a side seal fixed to the end face of the slider body 2A together with the end cap 5 via a screw 12 or the like, 10 denotes a tapped hole of the screw 12 formed on the end face of the slider body 2A, and 13 denotes A grease supply nipple 14 is a bolt insertion hole for fixing the guide rail 1.

ところで、低コストで良好な潤滑状態を長期間維持できるようにして給脂間隔を長くすると共に、磨耗や破損等を防して長寿命な直動案内軸受装置とするために、エンドキャップ５とサイドシール１１との間にフェルト状の潤滑剤供給部材を介装したものが提案されている。
潤滑剤供給部材は多孔質のフェルト材に潤滑油やグリース等の潤滑剤を含有させたもので、エンドキャップ５と同様に略コ字状に形成されており、コ字状両端部内側には案内レール１の転動体転動溝３に摺接して潤滑剤を供給する摺接部が突設されている。 By the way, in order to maintain a good lubrication state at a low cost for a long period of time and to increase the lubrication interval and to prevent wear and breakage, etc., a long-life linear motion guide bearing device is provided. The thing which interposed the felt-like lubricant supply member between the side seals 11 is proposed.

A slidable contact portion that slidably contacts the rolling element rolling groove 3 of the guide rail 1 and supplies lubricant is provided.

上記従来の直動案内軸受装置においては、潤滑剤供給部材を形成するフェルト材に潤滑剤を含ませる際には、フェルト材に潤滑剤を含浸しやすく、また、低コストで良好な潤滑状態を長期間維持できるようにして給脂間隔を長くすると共に、磨耗や破損等を防して長寿命な直動案内軸受装置とするためには潤滑剤供給部材から案内レールに十分な潤滑剤が供給されることが望まれる。

It is. In this embodiment, parts that are the same as those of the conventional linear guide bearing device already described with reference to FIG.

本発明の実施の形態の一例である直動案内軸受装置は、図１に示すように、スライダ２のエンドキャップ５とサイドシール１１との間に、潤滑油又はグリース等の潤滑剤を含有する多孔質のフェルト材１５ａから形成されると共に案内レール１の転動体転動溝３に摺接して潤滑剤を供給する潤滑剤供給部材１５が潤滑ユニットケース２０内に収容された状態でスライダ２の軸方向に複数枚介装されている。   As shown in FIG. 1, a linear guide bearing device that is an example of an embodiment of the present invention contains a lubricant such as lubricating oil or grease between an end cap 5 of a slider 2 and a side seal 11. A lubricant supply member 15 that is formed of a porous felt material 15 a and that slides into contact with the rolling element rolling groove 3 of the guide rail 1 to supply a lubricant is housed in the lubrication unit case 20. A plurality of sheets are interposed in the axial direction.

潤滑剤供給部材１５は、図２に示すように、ニードルパンチング加工（図３参照）を施してフェルト化されたシート状のフェルト材１５ａをエンドキャップ５と同様の略コ字状に打ち抜いて形成されており、コ字状両端部外側にはねじ１２の挿通用の固定リング（図示せず）が嵌め込まれる切欠き１８が形成され、コ字状両端部内側には案内レール１の転動体転動溝３に摺接して潤滑剤を供給する摺接部１７が突設されている。   As shown in FIG. 2, the lubricant supply member 15 is formed by punching a felt-like felt material 15 a that has been subjected to needle punching (see FIG. 3) into a substantially U-shape similar to the end cap 5. A notch 18 into which a fixing ring (not shown) for inserting the screw 12 is fitted is formed outside the both ends of the U-shape, and the rolling elements of the guide rail 1 are rolled inside the both ends of the U-shape. A sliding contact portion 17 is provided so as to project in sliding contact with the moving groove 3 and supply lubricant.

また、潤滑剤供給部材１５の案内レール１の上方に位置する上端部略中央には例えばリング状等の押圧部材（図示せず）が嵌め込まれる切欠き１９が形成されており、この切欠き１９に押圧部材を嵌め込んで潤滑剤供給部材１５の上端部をスライダ２の幅方向外方に押圧変形させることで、該潤滑剤供給部材１５の下端側に位置するコ字状両端部をスライダ２の幅方向内方に変形させて前記摺接部１７を案内レール１の転動体転動溝３に押圧するようにしている。   In addition, a notch 19 into which a pressing member (not shown) such as a ring shape is fitted is formed at the approximate center of the upper end portion of the lubricant supply member 15 located above the guide rail 1. The U-shaped both end portions located on the lower end side of the lubricant supply member 15 are moved to the slider 2 by pressing and deforming the upper end portion of the lubricant supply member 15 outward in the width direction of the slider 2 by fitting the pressing member into the slider 2. The sliding contact portion 17 is pressed against the rolling element rolling groove 3 of the guide rail 1 by being deformed inward in the width direction.

ここで、この実施の形態では、フェルト素材の性質及びニードルパンチング加工によるフェルト素材の異方性を利用して潤滑剤の供給量を調整すべく、潤滑剤供給部材１５の案内レール１への摺接部１７をフェルト材１５ａにニードルパンチング加工を施していない面３０とすると共に、ニードルパンチング加工を施していない面３０を前記打ち抜き時の切断面３１とし、更に、ニードルパンチング加工を施していない面３０からフェルト材１５ａに潤滑剤を含ませるようにしている。また、潤滑剤供給部材１５には、潤滑剤保持部として機能する肉盗み部４０を設けている。   In this embodiment, the lubricant supply member 15 is slid onto the guide rail 1 in order to adjust the supply amount of the lubricant by utilizing the properties of the felt material and the anisotropy of the felt material by needle punching. The contact portion 17 is a surface 30 on which the felt material 15a is not subjected to needle punching, the surface 30 which is not subjected to needle punching is the cut surface 31 at the time of punching, and the surface which is not subjected to needle punching From 30, a lubricant is included in the felt material 15a. Further, the lubricant supply member 15 is provided with a meat stealing unit 40 that functions as a lubricant holding unit.

Therefore, abundant lubricant can be supplied from the sliding portion 17 to the guide rail 1, and the lubricant is included in the felt material 15a from the surface 30 that is not subjected to needle punching. It is possible to easily impregnate the felt material 15a with the lubricant.

更に、ニードルパンチング加工を施した面を前記打ち抜き時の切断面３１とした場合、絡みあったフェルトが散けやすくなるが、この実施の形態では、ニードルパンチング加工を施していない面３０を前記打ち抜き時の切断面３１としているので、フェルトの損傷を防止することができる。
更に、潤滑剤供給部材１５に潤滑剤保持部として機能する肉盗み部４０を設けているので、フェルト材１５ａに潤滑剤をより含浸しやすくすることができると共に、潤滑剤保持量が多くなって良好な潤滑状態をより長期間に渡って保つことができる。 Further, when the surface subjected to the needle punching process is the cut surface 31 at the time of punching, the entangled felt is easily scattered. In this embodiment, the surface 30 not subjected to the needle punching process is punched out. Since the cut surface 31 is the time, felt damage can be prevented.
Further, since the meat supply portion 40 functioning as the lubricant holding portion is provided in the lubricant supply member 15, the felt material 15a can be more easily impregnated with the lubricant, and the amount of the lubricant retained is increased. Good lubrication can be maintained for a longer period of time.

なお、本発明は上記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲において適宜変更可能である。
例えば上記実施の形態では、潤滑剤供給部材１５の形成にニードルパンチング加工工程を有する場合を例に採ったが、ニードルパンチング加工工程を行わない場合には、潤滑剤供給部材１５の案内レール１への摺接部１７を前記内ち抜き時の切断面３１とすることで、摺接部１７から潤滑剤を放出しやすくなり、該摺動部１７から案内レール１に豊富な潤滑剤を供給することができ、また、前記切断面３１からフェルト材１５ａに潤滑剤を含ませることで、該潤滑剤を含浸しやすくすることができる。 In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
For example, in the above embodiment, the case of having the needle punching process for forming the lubricant supply member 15 is taken as an example, but when the needle punching process is not performed, the guide to the guide rail 1 of the lubricant supply member 15 is performed. By using the sliding contact portion 17 as the cut surface 31 at the time of the inner punching, it becomes easy to release the lubricant from the sliding contact portion 17, and abundant lubricant is supplied from the sliding portion 17 to the guide rail 1. In addition, by including a lubricant in the felt material 15a from the cut surface 31, the lubricant can be easily impregnated.
