Description

本発明は一種のリニアガイドに係り、特に一種の給油路調整構造を備えたリニアガイドに関する。   The present invention relates to a kind of linear guide, and more particularly to a linear guide provided with a kind of oil supply path adjustment structure.

現在のリニアガイドは、工業関連で広く使用されている。直線的な送り用伝動手段の精度を高める効果を果たす以外にも、摩擦による消耗率を抑え、エネルギー転換効率を上げたり、騒音を減らしたり、剛性を高くして破損しにくくすることができるなどの利点がある。このことから、現在の各種工業でリニアガイドを機械などに応用することは非常に重要であることは論ずるまでもない。   Current linear guides are widely used in industry. In addition to improving the accuracy of the linear feed transmission means, it can reduce the wear rate due to friction, increase energy conversion efficiency, reduce noise, increase rigidity, and make it difficult to break. There are advantages. From this, it goes without saying that it is very important to apply linear guides to machines and the like in various current industries.

リニアガイドの運行時には、各部品間の摩擦による消耗を防ぐために十分な潤滑が必要である。リニアガイドのスライダの両端部分に設置したエンドキャップは、複数の還流路、2本の給油路及び給油口を備えていて、この還流路が転動体を循環還流させる。この給油口には1つの給油ニップルが設置されていて、更にこの給油口はこの2本の給油路の一端とつながっている。この2本の給油路は通常この給油口の左右両側に分かれてこの還流路に通じており、これによって潤滑油をこの還流路に送り込んで転動体を潤滑する。リニアガイドには様々な取り付け方法があり、その内の一種に傾斜式の取り付け方法があるが、これは、リニアガイドを1つの傾斜面上に固定する方法である。この取り付け方法では、この2本の給油路の1本は高い位置にあって1本は低い位置となるために、潤滑油を給油口から注入すると、低い位置にある給油路の潤滑油の流量が高い位置にある給油路の流量より多くなるために、相対的に一方の還流路の転動体の潤滑が不足することとなる。   When operating the linear guide, sufficient lubrication is necessary to prevent wear due to friction between the parts. The end caps installed at both end portions of the slider of the linear guide are provided with a plurality of reflux paths, two oil supply paths, and an oil supply port, and the return paths circulate and reflux the rolling elements. One oil supply nipple is installed at the oil supply port, and the oil supply port is connected to one end of the two oil supply passages. The two oil supply passages are usually divided into the left and right sides of the oil supply port and communicated with the return passage, whereby lubricating oil is fed into the return passage to lubricate the rolling elements. There are various attachment methods for the linear guide, and one of them is an inclined attachment method. This is a method of fixing the linear guide on one inclined surface. In this mounting method, since one of the two oil supply passages is at a high position and one is at a low position, when lubricating oil is injected from the oil supply port, the flow rate of the lubricating oil in the oil supply passage at the low position is Therefore, the lubrication of the rolling elements in one of the reflux paths is relatively insufficient.

上述の問題に鑑み、特許文献1で一つの解決策が提出されている。これは、左右の給油路の間に1つの弁おもりを設置し、弁おもりの両側に固定されたバネが設けてあり、リニアガイドが傾斜しているときは、弁おもりが重力を受けて低い側にある給油路に滑動して低い側の給油路の通路が狭められ、それ以降の低い側の給油路への潤滑油の流量が少なくなり、相対的に高い側の給油路の潤滑油の流量が増加する。しかしながら、この給油路の通路の広さを調整する構造は複雑なため、組立に多くの時間を必要とする。また、バネには一定の寿命があり、長期にわたって押さえつけられていると弾性を失うし、バネが損傷した場合には調整機能を失ってしまうので、改善する必要がある。   In view of the above problems, Patent Document 1 proposes one solution. This is because one valve weight is installed between the left and right oil supply passages, springs fixed on both sides of the valve weight are provided, and when the linear guide is inclined, the valve weight is low due to gravity The lower oil supply passage is narrowed by sliding to the oil supply passage on the lower side, the flow rate of the lubricating oil to the lower oil supply passage thereafter is reduced, and the lubricating oil in the relatively higher oil supply passage is reduced. The flow rate increases. However, the structure for adjusting the width of the passage of the oil supply passage is complicated and requires a lot of time for assembly. Further, the spring has a certain life, and when it is pressed for a long time, it loses its elasticity, and when the spring is damaged, the adjustment function is lost, so it needs to be improved.

日本特開第2009−156376号公報Japanese Unexamined Patent Publication No. 2009-156376

そこで、本発明の主要な目的はこの2本の給油路の潤滑油の流量をほぼ同じにするとともに、この給油路の調整構造を簡素化することで組立時間を短縮し、また、この調整構造の使用寿命を延ばす、給油路調整構造を備えたリニアガイドを提供することにある。   Accordingly, the main object of the present invention is to make the flow rates of the lubricating oils of the two oil supply passages substantially the same, simplify the adjustment structure of the oil supply passages, and shorten the assembly time. An object of the present invention is to provide a linear guide having an oil supply passage adjusting structure that extends the service life of the oil supply passage.

本発明の特徴および技術内容のよりよい理解のために、本発明の実施方式の説明及び図面を参照していただきたい。ただし、この実施方式及び図面は説明及び参考用のものであり、これらにより本発明に対するいかなる制限も加えられるものではない。   For a better understanding of the features and technical contents of the present invention, please refer to the description of the implementation method of the present invention and the drawings. However, this implementation method and drawings are for explanation and reference, and these do not impose any limitation on the present invention.

図1から図5で示す、本発明の実施例を参照していただきたい。本発明は、給油路調整構造を備えたリニアガイドであって、1本のスライドレール(4)と、1つのスライダ(5)と、2つのエンドキャップと、を含む。   Please refer to the embodiment of the present invention shown in FIGS. The present invention is a linear guide having an oil supply path adjustment structure, and includes one slide rail (4), one slider (5), and two end caps.

1本のスライドレール(4)は、一方向に伸張した細長い構造をしたもので、この伸張の方向を軸方向と定義する。   One slide rail (4) has an elongated structure extending in one direction, and this extending direction is defined as an axial direction.

1つのスライダ(5)は、このスライドレール(4)に組みつけて設置し、このスライドレール(4)に対して往復移動が可能なものである。   One slider (5) is installed on the slide rail (4) and can be reciprocated with respect to the slide rail (4).

2つのエンドキャップは本実施例において、図1で示す通り、1つの本体(1)及び1枚のカバー(2)で構成されている。この2つのエンドキャップはそれぞれこのスライダ(5)の軸方向の両側の端面に取り付ける。この本体(1)には1つの給油口(10)、接続溝(14)、調整溝(11)及び2本の給油路(12、13)が設けられている。この調整溝は、本実施例では1つの楕円形であるが、円形または長方形でもよい。この給油口(10)の一方の端はこの接続溝(14)とこの調整溝(11)とつながっていて、更にこの調整溝(11)はこの2本の給油路(12、13)とつながっている。この調整溝(11)の深さ(L1)はこの2本の給油路(12、13)及びこの接続溝(14)の深さ(L2、L3)より深い。   In this embodiment, the two end caps are composed of one main body (1) and one cover (2) as shown in FIG. The two end caps are respectively attached to the end faces on both sides in the axial direction of the slider (5). The main body (1) is provided with one oil supply port (10), a connection groove (14), an adjustment groove (11), and two oil supply passages (12, 13). This adjustment groove is one oval in this embodiment, but may be circular or rectangular. One end of this oil filler port (10) is connected to this connection groove (14) and this adjustment groove (11), and this adjustment groove (11) is connected to these two oil supply passages (12, 13). ing. The depth (L1) of the adjustment groove (11) is deeper than the depths (L2, L3) of the two oil supply passages (12, 13) and the connection groove (14).

図5で示す通り、この調整溝(11)には1つの調整部品(3)が設けられている。この調整部品(3)の長さ(L4)はこの調整溝(11)の深さ(L1)よりわずかに短い。この調整溝(11)と接続溝(14)及びこの2本の給油路(12、13)の深さの設定、及び調整部品(3)の長さと調整溝(11)との関係は、この調整部品(3)をこの接続溝(14)及びこの2本の給油路(12、13)の中に落としてしまって調整部品(3)をなくさないようにするための意味がある。更に、この調整部品(3)をこの調整溝(11)の中に入れた後、このカバー(2)をこの本体(1)を覆うように設置することで、この調整部品(3)がエンドキャップから外れることを防止し、かつこの調整部品(3)が傾くことを防止する。本実施例の調整部品(3)は、1つのローラーであるが、ボールまたはその他の形状の物体とすることもできる。また、この給油口(10)のもう一方の端には1つの給油ニップル(7)を取り付けて、使用者が潤滑油をこの給油口(10)に注入しやすいようにする。   As shown in FIG. 5, one adjusting component (3) is provided in the adjusting groove (11). The length (L4) of this adjustment part (3) is slightly shorter than the depth (L1) of this adjustment groove (11). This adjustment groove (11), connection groove (14) and the depth setting of these two oil supply passages (12, 13), and the relationship between the length of the adjustment part (3) and the adjustment groove (11) It is meaningful to prevent the adjustment component (3) from being dropped by dropping the adjustment component (3) into the connection groove (14) and the two oil supply passages (12, 13). Furthermore, after this adjustment part (3) is placed in this adjustment groove (11), this cover (2) is installed so as to cover this main body (1). Prevents the cap from coming off and prevents the adjustment part (3) from tilting. The adjustment component (3) of the present embodiment is a single roller, but may be a ball or other shaped object. In addition, an oil supply nipple (7) is attached to the other end of the oil supply port (10) so that the user can easily inject lubricating oil into the oil supply port (10).

また、このエンドキャップの外端には更に1つの防塵片(6)が設けられている。この防塵片(6)は、このスライダ(2)の中への異物の進入を防いで、このリニアスライダの動きをスムーズにすることができる。この防塵片(6)とこのエンドキャップは2本のねじ(8)でこのスライダに固定されている。   Further, one dustproof piece (6) is provided at the outer end of the end cap. The dust-proof piece (6) prevents foreign matter from entering the slider (2), and the movement of the linear slider can be made smooth. The dust-proof piece (6) and the end cap are fixed to the slider with two screws (8).

再度図4を参照していただきたい。リニアスライダが傾斜した表面に装着されているときには図4のような形態を呈し、この調整部品(3)がリニアスライダの傾斜の角度によりその中の一方の給油路(12、13)と調整溝(11)との隙間を調節する。本実施例においては、この調整部品(3)は第2の給油路(13)と調整溝(11)との接続部分に位置していて、この第2の給油路(13)の開口部の面積を狭め、相対的に潤滑油の供給量を減らして、第1の給油路(12)を流れる潤滑油の量を増加させることとなる。なお、「増加」とは、調節部品を設置していない場合の第1の給油路の潤滑油の流量と相対的に比較して、という意味である。   Please refer to FIG. 4 again. When the linear slider is mounted on an inclined surface, it takes the form shown in FIG. 4, and this adjustment component (3) has one oil supply passage (12, 13) and an adjustment groove depending on the inclination angle of the linear slider. Adjust the gap with (11). In the present embodiment, the adjustment component (3) is located at a connection portion between the second oil supply passage (13) and the adjustment groove (11), and the opening of the second oil supply passage (13). The area is reduced, the amount of lubricating oil supplied is relatively reduced, and the amount of lubricating oil flowing through the first oil supply passage (12) is increased. Note that “increase” means relative to the flow rate of the lubricating oil in the first oil supply passage when no adjustment component is installed.

また、この調節部品(3)を設置した後、この調節部品(3)とこの第2の給油路(13)との間にはまだ隙間があって、潤滑油は重力の影響でこの隙間を通って第2の給油路(13)に進入することができるので、この第2の給油路(13)の潤滑油の流量が減りすぎることはない。これによって潤滑油がこの第1の給油路及び第2の給油路に比較的平均して流入するので、この2本の給油路(12、13)の潤滑油の流量はほぼ同じとなる。他に、本発明では従来の技術における調整構造を更に簡素化し、取り付け時間を大幅に短縮した。更に製品の耐久性を高めるために、調整部品は他の部品を使用することなく単純に自重で移動するようにした。上記の技術手段により、本発明は、本発明の目的を達成した。   In addition, after installing this adjustment part (3), there is still a gap between this adjustment part (3) and this second oil supply passage (13). Since the second oil supply passage (13) can be passed through, the flow rate of the lubricating oil in the second oil supply passage (13) does not decrease too much. As a result, the lubricating oil flows into the first oil supply passage and the second oil supply passage relatively on average, so that the flow rates of the lubricating oil in the two oil supply passages (12, 13) are substantially the same. In addition, in the present invention, the adjustment structure in the prior art is further simplified, and the mounting time is greatly shortened. Furthermore, in order to increase the durability of the product, the adjustment parts are simply moved by their own weight without using other parts. With the above technical means, the present invention has achieved the object of the present invention.

また、図6を参照していただきたい。これは本発明のもう1つの好適な実施例である。本実施例と前述の実施例との違いは以下の通りで、この調整溝(11)は長方形のアーチ状の構造をしていて、この調整溝(11)の幅はこの調整部品(3)の幅よりやや広い点にある。このため調整部品(3)を1つの固定された経路を移動させることができ、調整部品(3)で確実にこの給油路(12、13)の開口部の大きさを調整することができる。これ以外の部品の構造、配置及びその効果は前の実施例と同じであるため、ここで重ねて説明することはしない。   Please also refer to FIG. This is another preferred embodiment of the present invention. The difference between this embodiment and the previous embodiment is as follows. This adjustment groove (11) has a rectangular arch-like structure, and the width of this adjustment groove (11) is the adjustment part (3). The point is slightly wider than the width of. For this reason, the adjustment component (3) can be moved along one fixed path, and the size of the opening of the oil supply passage (12, 13) can be reliably adjusted by the adjustment component (3). Since the structure, arrangement, and effects of other parts are the same as those of the previous embodiment, they will not be described again here.
