Description
本発明は直線案内機構に係り、特に潤滑構造を備えるリニアガイドに関する。 The present invention relates to a linear guide mechanism, and more particularly to a linear guide having a lubricating structure.
一般的な周知のリニアガイド、例えば特許文献１に示されている技術では、潤滑剤をリニアガイドのエンドキャップから注入し、該エンドキャップに設けた3か所の隙間の潤滑剤導入路を通じて潤滑剤を循環溝に導入する。該循環溝は転動体の循環用に供するものであることから、転動体が転動して該循環溝を通過するときにのみ潤滑剤を塗布することができ、転動体にスライダーとレールとの間をスムーズに転動させることによりリニアガイドの耐用年数が延びる。 In a general well-known linear guide, for example, the technique disclosed in Patent Document 1, a lubricant is injected from an end cap of the linear guide, and lubricated through a lubricant introduction passage in three gaps provided in the end cap. The agent is introduced into the circulation groove. Since the circulation groove serves for circulation of the rolling element, the lubricant can be applied only when the rolling element rolls and passes through the circulation groove. The service life of the linear guide is extended by smoothly rolling the gap.
しかしながら、上述の潤滑構造を有するリニアガイドはマイクロインチング装置には不適である。マイクロインチング装置の機構は微少量の往復スライド運動をするに過ぎず、つまり、スライダーがレールに対し微小距離を繰り返し往復運動するだけであり、その距離はリニアガイドのサイズにより開きがあるが、一般的には5mm〜20mmである。そのためスライダーとレールの間に配設された転動体は循環溝に全く到達しないために潤滑が行われず、うまく潤滑が行われる転動体は循環溝付近にとどまっている数個のみに限られることから、長期間経過すると潤滑が行われなかった転動体とスライダー及びレールの間で摩耗が生じ、進行すると損傷あるいはノイズが発生したり、運行のスムーズさが損なわれたりする。したがって、この種の潤滑構造は改良する必要がある。 However, the linear guide having the above-described lubrication structure is not suitable for a micro inching device. The mechanism of the micro inching device is only a small amount of reciprocating slide movement, that is, the slider only reciprocates a small distance with respect to the rail, and the distance varies depending on the size of the linear guide. Specifically, it is 5 mm to 20 mm. For this reason, the rolling elements disposed between the slider and the rail do not reach the circulation groove at all, so lubrication is not performed, and only a few rolling elements that are well lubricated remain near the circulation groove. When a long period of time elapses, wear occurs between the rolling elements that have not been lubricated, the slider, and the rail, and when it progresses, damage or noise occurs, and smoothness of operation is impaired. Therefore, this type of lubricating structure needs to be improved.
本発明は上述の問題点に鑑み、その目的は一種の潤滑構造を開発して上述の使用環境における潤滑不均一の問題を改善し、さらに該潤滑構造がリニアガイドの各種利用状況に通用するようにすることである。 In view of the above-described problems, the present invention aims to develop a kind of lubrication structure to improve the problem of non-uniform lubrication in the above-mentioned use environment, and to make the lubrication structure applicable to various usage situations of the linear guide.

図１〜図6は実施例１を示す図面であり、本発明は潤滑構造を備えるリニアガイドの一種であり、次の内容を含む。 FIGS. 1-6 is drawing which shows Example 1, This invention is a kind of linear guide provided with a lubrication structure, The following content is included.
レール(1)は1本、一方向に伸びた棒状構造をしており、その延伸方向を軸方向(X)としたとき、該レール(1)は軸方向(X)に設けた4本の転動溝(11)を有する。スライダー(2)は1個、該レール(1)にはめて取り付け、該転動溝(11)に対応する転動溝(21)を有し、該転動溝(11)と転動溝(21)は4本の負荷軌道(90)を構成する。本実施例では4本の負荷軌道(90)を例として挙げているが、2本以上であれば全て本発明の技術を応用できる。 One rail (1) has a rod-like structure extending in one direction, and when the extending direction is the axial direction (X), the rail (1) has four rails provided in the axial direction (X). It has a rolling groove (11). One slider (2) is attached to the rail (1) and has a rolling groove (21) corresponding to the rolling groove (11), and the rolling groove (11) and the rolling groove ( 21) constitutes four load tracks (90). In this embodiment, four load tracks (90) are taken as an example, but the technique of the present invention can be applied to any two or more tracks.
また、該スライダー(2)には4本の循環孔(22)を設け、該循環孔(22)は基本的に該転動溝(21)に平行に設ける。非平行に設けると加工上の誤差が生じる可能性がある。エンドキャップ(3)2個は、該スライダー(2)の軸方向(X)の両端にそれぞれ設置する。両該エンドキャップ(3)はそれぞれ4個の循環路を有し、該循環路は本実施例ではエンドキャップ(3)の本体(31)とキャップパネル(32)に設けた半循環路(311、321)が組み合わさって構成され、該循環路はU字形であり、その両端でそれぞれ該負荷軌道(90)と該循環孔(22)に接続し、両該循環路、負荷軌道（90）1本及び循環孔(22)1本で循環経路1本を構成する。 The slider (2) is provided with four circulation holes (22), and the circulation holes (22) are basically provided in parallel with the rolling grooves (21). If it is provided non-parallel, processing errors may occur. Two end caps (3) are respectively installed at both ends in the axial direction (X) of the slider (2). Both the end caps (3) each have four circulation paths, and in this embodiment, the circulation paths are half circulation paths (311 provided in the main body (31) and the cap panel (32) of the end cap (3). , 321) and the circulation path is U-shaped, and both ends thereof are connected to the load track (90) and the circulation hole (22), respectively, and both the circulation path and the load track (90) One circulation path is composed of one and one circulation hole (22).
したがって、本実施例では4本の循環経路を有する。かつ、該エンドキャップ(3)には潤滑剤導入路(33)を設け、該導入路(33)の一端は外部の潤滑剤供給装置に接続し、該潤滑剤供給装置が潤滑剤またはグリースを供給し、他の一端の開口部(331)は該負荷軌道(90)に隣接して軸方向(X)に設ける。転動体(7)は複数個、各該循環経路に配設する。本実施例では該転動体(7)がスライダー(2)上でレール(1)から離れても転動溝(21)上に保持されるよう、スライダー(2)上に保持器3個を設け、それぞれ上保持器(4)、中保持器(5)、下保持器(6)とし、転動体(7)が脱落して組み立て直す必要が生じないようにする。 Therefore, this embodiment has four circulation paths. Further, the end cap (3) is provided with a lubricant introduction path (33), one end of the introduction path (33) is connected to an external lubricant supply device, and the lubricant supply device supplies the lubricant or grease. The opening (331) at the other end is provided in the axial direction (X) adjacent to the load track (90). A plurality of rolling elements (7) are arranged in each circulation path. In this embodiment, three cages are provided on the slider (2) so that the rolling element (7) is held on the rolling groove (21) even if it is separated from the rail (1) on the slider (2). The upper cage (4), the middle cage (5), and the lower cage (6) are used to prevent the rolling element (7) from dropping and reassembling.
以上、本実施例の各部品の構造と部品の組合せ方を説明した。以下に本発明の潤滑構造の実施形態を説明する。 In the above, the structure of each part of this embodiment and how to combine the parts have been described. Embodiments of the lubricating structure of the present invention will be described below.
図3〜図6に示すように、該スライダー(2)の両側にそれぞれ間隔を空けて配した2列の転動溝(21)を設け、両該転動溝(21)間に内側平面(23)を設け、該中保持器(5)はガイド面(51)を有し、該ガイド面(51)は該内側平面(23)に対して一定の間隔を空けて設ける。該内側平面(23)と該ガイド面(51)との隙間を潤滑剤供給部(80)と称することとすると、該潤滑剤供給部(80)を該潤滑剤導入路(33)の開口部(331)に接続し、該開口部(331)から潤滑剤を該潤滑剤供給部(80)に供給すると、潤滑剤は該潤滑剤供給部(80)に沿って流出し、つまり軸方向(X)に流出し、次第に軸方向(X)の法線方向に流出して両側の負荷軌道(90)に至り、負荷軌道(90)に位置する各該転動体(7)を潤滑する。 As shown in FIG. 3 to FIG. 6, two rows of rolling grooves (21) are provided on both sides of the slider (2) at an interval, and an inner plane (between the rolling grooves (21)) ( 23), the inner cage (5) has a guide surface (51), and the guide surface (51) is provided at a certain distance from the inner plane (23). When the gap between the inner flat surface (23) and the guide surface (51) is referred to as a lubricant supply section (80), the lubricant supply section (80) is connected to the opening of the lubricant introduction path (33). (331) and supplying lubricant from the opening (331) to the lubricant supply section (80), the lubricant flows out along the lubricant supply section (80), that is, in the axial direction ( X), gradually flows in the normal direction of the axial direction (X), reaches the load track (90) on both sides, and lubricates the rolling elements (7) located on the load track (90).
さらに、図7〜図9は実施例2を示す図面である。本実施例と実施例1との違いは、該中保持器(5)のガイド面(51)を該内側平面(23)にぴったり付くように設けることである。ただし、中保持器(5)は樹脂射出成形品であり、長さが比較的長いことから多少の変形を免れず、局部的に完全にぴったり付かない部分もあるが、そのような部分が最終的な潤滑効果に影響することはない。 Further, FIGS. 7 to 9 are drawings showing Example 2. FIGS. The difference between the present embodiment and the first embodiment is that the guide surface (51) of the inner cage (5) is provided so as to be closely attached to the inner plane (23). However, the inner cage (5) is a resin injection molded product, and since its length is relatively long, some deformation is not avoided and there are some parts that do not fit perfectly locally. This does not affect the overall lubrication effect.
また、該保持器(5)のガイド面(51)にへこませて軸方向(X)に設けた軸方向流路(511)を設け、該軸方向流路(511)を該開口(331)に接続し、さらに、軸方向(X)の法線方向に作り、間隔を空けて複数配列した横方向流路(512)を設け、該横方向流路(512)を該軸方向流路(511)と一体化させることにより、該軸方向流路(511)及び該横方向流路(512)が該内側平面(23)と共に潤滑剤供給部(80)を構成する。潤滑剤を該開口部(331)から該軸方向流路(511)に注入すると、潤滑剤は次第に横方向流路(512)に流出し、潤滑剤が負荷軌道(90)に位置する各該転動体(7)に供給される。さらに、各該横方向流路(512)の大きさを変えて各部位の潤滑剤の流出量を制御することができる。その他の部品の構造、組合せ方及び効果は実施例1と同じであり、ここでは省略する。 Further, an axial flow path (511) provided in the axial direction (X) by being recessed into the guide surface (51) of the cage (5) is provided, and the axial flow path (511) is provided in the opening (331 ), And in the normal direction of the axial direction (X), a plurality of lateral flow channels (512) arranged at intervals are provided, and the horizontal flow channel (512) is provided as the axial flow channel. By integrating with (511), the axial flow path (511) and the lateral flow path (512) together with the inner plane (23) constitute a lubricant supply section (80). When the lubricant is injected into the axial flow path (511) from the opening (331), the lubricant gradually flows out into the lateral flow path (512), and the lubricant is located in the load track (90). Supplied to the rolling elements (7). Further, it is possible to control the outflow amount of the lubricant in each part by changing the size of each lateral flow path (512). The structure, combination method, and effects of other parts are the same as those in the first embodiment, and are omitted here.
最後に、図10〜図12は実施例3を示す図面である。本実施例の実施例1との違いは、該中保持器(5)のガイド面(51)がV字形構造、つまり該ガイド面(51)が夾角(Q)をなす2平面で構成されていることであり、これはそれぞれ夾角をなす多数の平面で構成されてもよく、また、円弧状の曲面で構成されてもよい。したがって、ガイド面(51)は内側平面(23)に対して一定の間隔を空けて設けるが、ガイド面(51)の設計により該間隔の寸法が徐々に変化するため、ガイド面(51)の設計構造は各部分の寸法が全て異なるように見える。 Finally, FIGS. 10 to 12 are diagrams showing a third embodiment. The difference between the present embodiment and the first embodiment is that the guide surface (51) of the inner cage (5) has a V-shaped structure, that is, the guide surface (51) has two planes forming a depression angle (Q). This may be composed of a number of flat surfaces each forming a depression angle, or may be composed of an arcuate curved surface. Therefore, although the guide surface (51) is provided with a certain distance from the inner plane (23), the dimension of the distance gradually changes depending on the design of the guide surface (51). The design structure appears to have different dimensions for each part.
しかしながら、本実施例では両該平面は対称的に設計しているため、両該平面の互いに対応する位置における間隔の寸法は同じである。また、該保持器(5)のガイド面(51)はへこませて軸方向(X)に設けた軸方向流路(511)を有し、該軸方向流路(511)は該開口部(331)に接続し、該軸方向流路(511)とガイド面(51)は該内平面(23)と共に潤滑剤供給部(80)を構成する。潤滑剤を該開口部(331)から該軸方向流路(511)に注入すると、潤滑剤は次第にガイド面(51)と内側平面(23)との隙間に流出し、潤滑剤が負荷軌道(90)に位置する各該転動体(7)に供給される。付け加えると、本実施例では、第12図に示すようにガイド面(51)と内側平面(23)の開口部(331)における間隔の寸法を比較的小さく、中間位置に向かって徐々に大きくしており、このように設計する主な目的は潤滑剤を負荷軌道(90)に均一に分布させることであり、開口部(331)に近づくほど潤滑剤の注入圧力が大きくなるため、小さい間隔寸法で潤滑剤を該隙間に流出させることができ、余った潤滑剤が潤滑剤供給部(80)の中間部位に向かって流出することにより、中間部の負荷軌道(90)に速やかに潤滑剤を行き渡らせられる。その他の部品の構造、組合せ方及び効果は実施例1と同じであり、ここでは省略する。 However, in the present embodiment, the two planes are designed symmetrically, and therefore the distance between the planes at the positions corresponding to each other is the same. Further, the guide surface (51) of the cage (5) has an axial flow path (511) that is recessed and provided in the axial direction (X), and the axial flow path (511) is the opening portion. (331), the axial flow path (511) and the guide surface (51) together with the inner plane (23) constitute a lubricant supply section (80). When lubricant is injected into the axial flow path (511) from the opening (331), the lubricant gradually flows out into the gap between the guide surface (51) and the inner plane (23), and the lubricant is loaded into the load track ( 90) is supplied to each of the rolling elements (7). In addition, in this embodiment, as shown in FIG. 12, the distance between the guide surface (51) and the opening (331) of the inner plane (23) is relatively small and gradually increased toward the intermediate position. The main purpose of designing in this way is to distribute the lubricant evenly on the load track (90), and the closer to the opening (331), the larger the injection pressure of the lubricant. Thus, the lubricant can flow out into the gap, and the excess lubricant flows out toward the intermediate portion of the lubricant supply section (80), so that the lubricant can be quickly applied to the load track (90) in the intermediate section. I can get around. The structure, combination method, and effects of other parts are the same as those in the first embodiment, and are omitted here.
