Description

本発明はリニアガイドウェーに係り、特に転がり素子がより順調に転がることができる転がり素子保持チェーン付きリニアガイドウェーに関するものである。   The present invention relates to a linear guideway, and more particularly to a linear guideway with a rolling element holding chain that allows rolling elements to roll more smoothly.

転がり素子保持チェーン付きリニアガイドウェーは既に各種類の精密摺動装置に使用され、例えばデジタル制御設備の工作機械と自動溶接装置と運搬装置などに使用される。
一般のリニアガイドウェーの形態は、一つの転がり素子保持チェーンが環状の転がり通路に沿って循環して連続に転がり、また、転がり素子保持チェーンを有するリニアガイドウェーは循環通路の全体に、転がり素子保持チェーンを収容するための保持チェーン連接部用収容溝を設置することが必要である。
しかしながら、保持チェーン連接部用収容溝は単一の部材で構成することができなく、多数の部材の組合であれば、段差が発生するので、転がり素子保持チェーンの転がりが順調にいかなくなる。 Linear guideways with rolling element holding chains are already used in various types of precision sliding devices, for example, in machine tools, automatic welding devices, and conveying devices of digital control equipment.
A general linear guideway is configured such that a single rolling element holding chain circulates along an annular rolling path and continuously rolls, and a linear guideway having a rolling element holding chain has a rolling element in the entire circulation path. It is necessary to install a holding groove for connecting the holding chain for receiving the holding chain.
However, the holding groove for connecting the holding chain connecting portion cannot be constituted by a single member, and if it is a combination of a large number of members, a step is generated, so that the rolling of the rolling element holding chain does not proceed smoothly.

図１と図２に示すのは、一般の転がり素子保持チェーン付きリニアガイドウェーであり、スライダ本体１１がリニアガイドウェーに設置される。
また、リニアガイドウェーは、一つの荷重側保持器１２と、一つの回流部保持器１３とから構成されたものであり、且つ荷重側保持器１２と回流部保持器１３には互いに連通し転がり素子保持チェーン１４を収容するための保持チェーン連接部用収容溝１２１，１３１が設けてある。
また、転がり素子保持チェーン１４の形態は、図３に示すように、複数の間隔部１４３が組付けた一つの連接部１４１で構成されたものであり、且つ各転がり素子１４２が間隔部１４３で離間される。 FIG. 1 and FIG. 2 show a general linear guideway with a rolling element holding chain, and a slider main body 11 is installed on the linear guideway.
The linear guideway is composed of one load side retainer 12 and one circulation part retainer 13, and the load side retainer 12 and the circulation part retainer 13 communicate with each other and roll. Holding chain connecting portion receiving grooves 121 and 131 for receiving the element holding chain 14 are provided.
Further, as shown in FIG. 3, the rolling element holding chain 14 is configured by one connecting portion 141 in which a plurality of spacing portions 143 are assembled, and each rolling element 142 is a spacing portion 143. Spaced apart.

また、転がり素子保持チェーン付きリニアガイドウェーの進行を順調にするために、部材の組合で発生した段差が回流部保持器と荷重側保持器の連接面に位置しないように設計し、転がり素子保持チェーンにある連接部は進行しているので段差箇所を順調に越えるようにしたものもある（例えば、特許文献１参照。）。   Also, in order to make the progress of the linear guideway with rolling element holding chain smooth, it is designed so that the step generated by the combination of members is not located on the connecting surface of the circulating part holder and load side holder, and the rolling element holding Since the connecting part in the chain is advancing, there are also parts that smoothly cross the stepped portion (for example, see Patent Document 1).

特許第３３４９２３８号明細書Japanese Patent No. 3349238

前記した従来の技術には、次のような問題点がある。
従来の回流部保持器１３にある保持チェーン連接部用収容溝１３１と荷重側保持器１２にある保持チェーン連接部用収容溝１２１の連接する箇所は特別な設計が施されなく、転がり素子保持チェーン１４にある連接部１４１が回流部保持器１３から荷重側保持器１２に進入するときに、間隔部１４３の移動が不順調になる。 The conventional techniques described above have the following problems.
No special design is applied to the connecting portion of the holding chain connecting portion receiving groove 131 in the conventional circulating portion holder 13 and the holding chain connecting portion receiving groove 121 in the load side holder 12, and the rolling element holding chain is not designed. When the connecting portion 141 at 14 enters the load side retainer 12 from the circulating portion retainer 13, the movement of the interval portion 143 becomes irregular.

また以下の点についても問題となる
（１）リニアガイドウェーに使用される転がり素子保持チェーン１４は撓み特性を持つ樹脂材料で形成され、その目的は転がり素子保持チェーン１４が回流部保持器１３を順調に通過可能にする点にある。
連接部１４１が回流部保持器１３と荷重側保持器１２の連接する箇所に近接する所には、素材本体の弾性の原因で、図４に示すように、連接部１４１は回流部保持器１３にある保持チェーン連接部用収容溝１３１の外縁に当たり、且つ図４において、転がり素子保持チェーン１４が矩形線で表示された。
間隔部１４３は、連接箇所に到達したときに、転がり素子保持チェーン１４が設計通りに前進せず、角度ズレが発生する。
そのずれた状態を図５に表示すると、矢印方向は実際の前進方向であり、中空な矢印方向は予定した前進方向である。 The following points also become a problem: (1) The rolling element holding chain 14 used for the linear guideway is formed of a resin material having a bending characteristic, and the purpose of the rolling element holding chain 14 is to connect the circulating portion holder 13 to the rolling element holding chain 14. The point is that it can pass smoothly.
As shown in FIG. 4, the connecting portion 141 is located near the location where the connecting portion 141 is connected to the connecting portion of the circulating portion holder 13 and the load side holder 12. 4, and the rolling element holding chain 14 is indicated by a rectangular line in FIG. 4.
When the spacing portion 143 reaches the connection location, the rolling element holding chain 14 does not advance as designed, and an angle shift occurs.
When the shifted state is displayed in FIG. 5, the arrow direction is the actual forward direction, and the hollow arrow direction is the planned forward direction.

（２）荷重側保持器１２を別の部材に組付けるときには、一般的にピンによる結合方式を採用するが、合わせ公差および製造ミスを考慮して、荷重側保持器１２にある保持チェーン連接部用収容溝１２１と回流部保持器１３にある保持チェーン連接部用収容溝１３１の間には段差が発生する。 (2) When the load-side cage 12 is assembled to another member, a pin coupling method is generally adopted. However, in consideration of alignment tolerances and manufacturing errors, the holding chain connecting portion in the load-side cage 12 A step is generated between the holding groove 121 for the holding chain and the holding groove 131 for the holding chain connecting portion in the circulating portion holder 13.

上記の問題が原因で、図６に示すように、転がり素子保持チェーン１４にある連接部１４１は、回流部保持器１３にある保持チェーン連接部用収容溝１３１の出口を通過するときに、荷重側保持器１２にある保持チェーン連接部用収容溝１２１のエッジに当たり、だから、転がり素子保持チェーン１４の進行が不順調になる。   Due to the above problem, as shown in FIG. 6, the connecting portion 141 in the rolling element holding chain 14 is loaded when passing through the outlet of the holding chain connecting portion receiving groove 131 in the circulating portion holder 13. It strikes the edge of the holding chain connecting portion receiving groove 121 in the side cage 12, and therefore, the rolling element holding chain 14 advances unsteadily.

転がり素子保持チェーン付きリニアガイドウェーの進行を順調にするために、特許３３４９２３８号公報に開示された発明が提案され、部材の組合で発生された段差が回流部保持器と荷重側保持器の連接面に位置しないように設計し、転がり素子保持チェーンにある連接部は進行しているので段差箇所を順調に越えるようになった。
しかしながら、このような設計は、生産性が良くなく、且つ部材は樹脂射出成形方法で作製されるので、長さ対幅の比例は大きすぎて、製品寸法の収縮が把握できなく、組付け作業が難しくなる。 In order to make the progress of the linear guideway with a rolling element holding chain smooth, the invention disclosed in Japanese Patent No. 3349238 has been proposed, and a step generated by a combination of members is connected to the circulating part holder and the load side holder. It was designed not to be located on the surface, and the connecting part in the rolling element holding chain has progressed, so that it has successfully passed the stepped portion.
However, such a design is not productive, and the members are made by a resin injection molding method. Therefore, the ratio of length to width is too large, and the shrinkage of the product dimensions cannot be grasped. Becomes difficult.

以上の点に鑑みて、本発明の第一の目的は、転がり素子がより順調に転がることができる転がり素子保持チェーン付きリニアガイドウェーを提供するものである。   In view of the above, a first object of the present invention is to provide a linear guideway with a rolling element holding chain that allows rolling elements to roll more smoothly.

本発明の第二の目的は、組付ける部材の製造が容易になる転がり素子保持チェーン付きリニアガイドウェーを提供するものである。
A second object of the present invention is to provide a linear guideway with a rolling element holding chain that makes it easy to manufacture a member to be assembled.

本発明に係る転がり素子保持チェーン付きリニアガイドウェーによれば、転がり素子はより順調に転がることができ、且つ組付ける部材の製造が容易になる。   According to the linear guideway with a rolling element holding chain according to the present invention, the rolling element can roll more smoothly and manufacture of a member to be assembled is facilitated.

以下、添付図面を参照して本発明の好適な実施の形態を詳細に説明する。   Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

まず、図７を参照する。
本発明に係る転がり素子保持チェーン付きリニアガイドウェーは、一つの荷重側保持器２０と、一つの回流部保持器３０とから構成される。
且つ荷重側保持器２０と回流部保持器３０とには互いに連通し連接部４１にある転がり素子保持チェーン４０を収容するための保持チェーン連接部用収容溝２１，３１が設けてあり、なお、前記荷重側保持器２０の保持チェーン連接部用収容溝２１の開口２２では案内斜面５０が設けてあり、且つ案内斜面５０は回流部保持器３０にある保持チェーン連接部用収容溝３１との連接箇所に位置する。 First, referring to FIG.
The linear guideway with a rolling element holding chain according to the present invention includes one load side holder 20 and one circulation part holder 30.
The load side retainer 20 and the circulation portion retainer 30 are provided with retaining chain connecting portion receiving grooves 21 and 31 for receiving the rolling element holding chains 40 in the connecting portion 41 which are in communication with each other. A guide slope 50 is provided in the opening 22 of the holding chain connecting portion receiving groove 21 of the load side retainer 20, and the guide inclined surface 50 is connected to the holding chain connecting portion receiving groove 31 in the circulating portion holder 30. Located in the place.

図８に示すように、本発明は部材を変更しない前提で、案内斜面５０の設計により、転がり素子保持チェーン４０の一端にある連接部４１の進行方向に発生したズレが吸収され、これにより、転がり素子保持チェーン４０にある連接部４１は、荷重側保持器２０と回流部保持器３０の連接箇所での段差を順調に越えることができる。
本発明では、荷重側保持器２０の構造を大幅に変更することが必要ないので、製造が容易になり、且つ樹脂射出成形によって成形されるので、寸法変動が少ない。
このため、転がり素子はより順調に転がることができ、且つ組付ける部材の製造が容易になる。 As shown in FIG. 8, the present invention is based on the premise that the member is not changed, and the deviation generated in the traveling direction of the connecting portion 41 at one end of the rolling element holding chain 40 is absorbed by the design of the guide slope 50, thereby The connecting portion 41 in the rolling element holding chain 40 can smoothly exceed the step at the connecting portion between the load side holder 20 and the circulating portion holder 30.
In the present invention, since it is not necessary to significantly change the structure of the load-side cage 20, manufacturing is facilitated and molding is performed by resin injection molding.
For this reason, a rolling element can roll more smoothly and manufacture of the member to assemble becomes easy.

案内斜面５０の寸法は計算により導き出すことが必要であり、その計算式は下記に示す。   The dimensions of the guide slope 50 must be derived by calculation, and the calculation formula is shown below.

まず、図９に示すように、転がり素子保持チェーン４０にある連接部４１を弾性の回復性が極めて大きいものと仮定し、そうすると、案内斜面の必要な最大幅を求めることができる。
なお、二つの位置制限点があると仮定し、Ａ点は回流部保持器３０にある保持チェーン連接部用収容溝３１の開口の外縁にある角部の先端であり、Ｂ点は回流部保持器３０にある保持チェーン連接部用収容溝３１の内壁が転がり素子保持チェーン４０にある連接部４１の厚さを補償する曲線と転がり素子保持チェーン４０にある外縁の接点である。
本実施例では、曲線方程式が円方程式であり、すなわち、回流部は半円状を呈する。 First, as shown in FIG. 9, it is assumed that the connecting portion 41 in the rolling element holding chain 40 has extremely high resiliency of elasticity, and then the required maximum width of the guide slope can be obtained.
Assuming that there are two position limiting points, point A is the tip of the corner at the outer edge of the opening of the holding chain connecting portion receiving groove 31 in the circulating portion holder 30, and point B is the circulating portion holding point. The inner wall of the holding chain connecting portion receiving groove 31 in the container 30 is a curve that compensates for the thickness of the connecting portion 41 in the rolling element holding chain 40 and an outer edge contact point in the rolling element holding chain 40.
In the present embodiment, the curve equation is a circular equation, that is, the circulating part has a semicircular shape.

次に、図１０を参照する、図１０における各パラメータは、ａは回流部保持器と荷重側保持器にある保持チェーン連接部用収容溝の連接箇所での段差であり、ｂは回流部保持器の保持チェーン連接部用収容溝の幅であり、ｃは転がり素子保持チェーンの連接部の厚さであり、ｋは案内斜面の先端のＸ軸座標であり、ｒは回流部保持器の回流通路の半径であり、Ｐは案内斜面の先端の座標（すなわち、転がり素子保持チェーンのもっとも外側の接触点）であり、ｅｑ１は転がり素子保持チェーンにある連接部の外縁と接する曲線方程式（本実施例では円）であり、ｅｑ２は転がり素子保持チェーンにある連接部の外縁の直線方程式であり、ｅｑ２の傾斜度は-ｄ（本実施例ではｄ＜０）であり、なお、   Next, referring to FIG. 10, each parameter in FIG. 10 is a step at a connecting portion of the holding groove connecting portion accommodation groove in the circulating portion retainer and the load side retainer, and b is the circulating portion holding. C is the thickness of the connecting part of the rolling element holding chain, k is the X-axis coordinate of the tip of the guide slope, and r is the rotation of the circulating part holder. The radius of the flow path, P is the coordinates of the tip of the guide slope (that is, the outermost contact point of the rolling element holding chain), and eq1 is a curve equation (this book) that touches the outer edge of the connecting portion in the rolling element holding chain Eq2 is a linear equation of the outer edge of the connecting portion in the rolling element holding chain, and the slope of eq2 is −d (d <0 in this embodiment),

次に、図１１を参照する。図１１に表示された各パラメータは、αは転がり素子保持チェーンにある連接部と水平線から成す角度であり、γ＝９０°−βは案内斜面の角度であり、Ｌは案内斜面の幅であり、だから、 It becomes.
Reference is now made to FIG. Each parameter displayed in FIG. 11 is that α is an angle formed by the connecting portion in the rolling element holding chain and a horizontal line, γ = 90 ° −β is an angle of the guide slope, and L is a width of the guide slope. So,
