Description

本発明は、案内レールの転動体軌道面とスライダの転動体軌道面との間を転動する転動体としてローラ形状の転動体を用いた直動案内軸受装置に関し、特に、隣り合う二つの転動体の間に保持ピースと称される間隔体を介在させた直動案内軸受装置の改良に関する。   The present invention relates to a linear guide bearing device using a roller-shaped rolling element as a rolling element that rolls between a rolling element raceway surface of a guide rail and a rolling element raceway surface of a slider. The present invention relates to an improvement of a linear motion guide bearing device in which a spacing body called a holding piece is interposed between moving bodies.

従来、この種の直動案内軸受装置は隣り合う二つの転動体がスライダ内の転動体戻し通路や転動体方向転換路で衝突し合うことを保持ピースによって防止できるという利点を有しているが、スライダ内の転動体戻し通路や転動体方向転換路に転動体と保持ピースを交互に組み入れたときに保持ピースの倒れが生じると、転動体のスムーズな転がり運動が阻害される要因となる。そこで、図８に示すように、保持ピース１４の左右側面部に腕部１４ｃを設け、この腕部１４ｃによって保持ピース１４の倒れを防止するようにした直動案内軸受装置が知られている（例えば、特許文献１参照）。
特開２００５−１８０６５６号公報 Conventionally, this type of linear motion guide bearing device has the advantage that the holding piece can prevent two adjacent rolling elements from colliding with each other in the rolling element return path or the rolling element direction changing path in the slider. When the rolling element and the holding piece are alternately inserted into the rolling element return path or the rolling element direction changing path in the slider, if the holding piece falls down, smooth rolling motion of the rolling element is hindered. Therefore, as shown in FIG. 8, there is known a linear motion guide bearing device in which arm portions 14c are provided on the left and right side portions of the holding piece 14, and the holding portion 14 is prevented from falling by the arm portion 14c. For example, see Patent Document 1).
JP 2005-180656 A

しかしながら、上述した直動案内軸受装置では、腕部１４ｃが保持ピース１４の左右側面中央部に設けられている。このため、転動体９の端面部と腕部１４ｃとの間に入り込んだ異物によって腕部１４ｃが保持ピース１４の左右側面部から離れる方向に変形すると、腕部１４ｃの根元部に過大な応力が発生し、保持ピース１４が破損するおそれがあった。
本発明は上述した問題点に着目してなされたものであり、その目的は、保持ピースの破損を抑制することのできる直動案内軸受装置を提供することにある。 However, in the linear motion guide bearing device described above, the arm portion 14 c is provided at the center of the left and right side surfaces of the holding piece 14. For this reason, if the arm portion 14c is deformed in a direction away from the left and right side surfaces of the holding piece 14 due to foreign matter entering between the end surface portion of the rolling element 9 and the arm portion 14c, excessive stress is applied to the root portion of the arm portion 14c. The holding piece 14 may be damaged.
The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide a linear motion guide bearing device capable of suppressing breakage of a holding piece.

上記課題を解決するために、請求項１記載の発明に係る直動案内軸受装置は、案内レールの転動体軌道面とスライダの転動体軌道面との間を転動する複数の転動体がローラ形状をなし、かつ転動体同士の間隔を転動体が干渉し合わない間隔に保つ保持ピースが該保持ピースの左右側面部に保持ピース倒れ防止用の腕部を有する直動案内軸受装置において、前記腕部の中心線が前記保持ピースの前後に位置する二つの転動体の中心を通る直線と重なり合わないように、前記腕部を前記保持ピースの左右側面部に設けたことを特徴とする。   In order to solve the above-mentioned problem, in the linear motion guide bearing device according to the first aspect of the present invention, a plurality of rolling elements rolling between the rolling element raceway surface of the guide rail and the rolling element raceway surface of the slider are rollers. In the linear motion guide bearing device, the holding piece having a shape and maintaining the interval between the rolling elements at an interval at which the rolling elements do not interfere with each other has arm portions for preventing the holding piece from falling on the left and right side surfaces of the holding piece. The arm portion is provided on the left and right side portions of the holding piece so that the center line of the arm portion does not overlap with a straight line passing through the centers of the two rolling elements located before and after the holding piece.

A plurality of rolling elements 9 (see FIG. 1) provided between the rolling elements roll between the rolling element raceway surfaces 7 and 8 by the relative movement of the slider 2 in the longitudinal direction of the guide rail 1. . And the rolling element 9 which rolled between the rolling element raceway surfaces 7 and 8 is introduced into the rolling element direction change path (not shown) formed between the end cap 4 and the return guide, and this rolling element direction. The direction is changed at the turning path.

スライダ本体３は袖部３ａの内部に複数（例えば二つ）の転動体戻し通路１０（図４参照）を有しており、転動体方向転換路で方向転換した転動体９はスライダ本体３の転動体戻し通路１０に導入され、この転動体戻し通路１０内を通って元の位置に戻されるようになっている。なお、転動体戻し通路１０はスライダ本体３の前後方向に貫通する貫通孔をスライダ本体３の袖部３ａに孔明け加工した後、この貫通孔に樹脂製スリーブ１１を挿入して形成されている。   The slider body 3 has a plurality of (for example, two) rolling element return passages 10 (see FIG. 4) inside the sleeve portion 3 a, and the rolling element 9 changed in direction by the rolling element direction changing path is the slider body 3. It is introduced into the rolling element return passage 10 and returned to the original position through the rolling element return passage 10. The rolling element return passage 10 is formed by drilling a through-hole penetrating in the front-rear direction of the slider body 3 in the sleeve portion 3a of the slider body 3, and then inserting a resin sleeve 11 into the through-hole. .

転動体軌道面７と転動体軌道面８との間に介在する転動体９は、組立時や分解時にスライダ２からの脱落を防止するために、スライダ２に組み付けられた転動体保持器１３（図１参照）に保持されている。また、転動体９はローラ形状をなしており、隣り合う二つの転動体９の間には、転動体同士の干渉を防止する目的で、図５に示すような保持ピース１４が設けられている。   The rolling element 9 interposed between the rolling element raceway surface 7 and the rolling element raceway surface 8 is provided with a rolling element holder 13 (attached to the slider 2 in order to prevent the rolling element 9 from falling off during assembly or disassembly. (See FIG. 1). Further, the rolling element 9 has a roller shape, and a holding piece 14 as shown in FIG. 5 is provided between two adjacent rolling elements 9 for the purpose of preventing interference between the rolling elements. .

保持ピース１４は合成樹脂材を射出成形して形成されており、この保持ピース１４には、転動体９の周面部と接触する矩形状の転動体接触面１４ａ，１４ｂが転動体９の直径とほぼ同じ曲率半径で形成されている。また、保持ピース１４は保持ピース１４の倒れを防止する一対の腕部１４ｃ，１４ｃを有しており、これらの腕部１４ｃは、腕部１４ｃの中心線Ｌ１が保持ピース１４の前後に位置する二つの転動体９の中心Ｏ１，０２を通る直線Ｌ２と重なり合わないように（好ましくは、腕部１４ｃが保持ピース１４の前後に位置する二つの転動体９の中心Ｏ１，０２を通る直線Ｌ２より保持ピース１４の上側または下側に位置するように）、保持ピース１４の左右側面部１４ｄ，１４ｅに設けられている。なお、転動体９の直径をＤとすると、保持ピース１４の高さｈはｈ＜Ｄとなっている。   The holding piece 14 is formed by injection-molding a synthetic resin material. The holding piece 14 has rectangular rolling element contact surfaces 14 a and 14 b that are in contact with the peripheral surface portion of the rolling element 9 and the diameter of the rolling element 9. It is formed with almost the same radius of curvature. In addition, the holding piece 14 has a pair of arm portions 14c and 14c that prevent the holding piece 14 from falling down, and the center line L1 of the arm portion 14c is positioned before and after the holding piece 14 in these arm portions 14c.

L3 (see FIG. 5) becomes longer. As a result, even if the arm portion 14c is deformed in a direction away from the left and right side surface portions 14d and 14e of the holding piece 14 due to foreign matter entering between the end surface portion of the rolling element 9 and the arm portion 14c of the holding piece 14, the holding piece 14 Since it is difficult for excessive stress to occur at the joint portion between the left and right side surface portions 14d, 14e and the arm portion 14c, the holding piece 14 can be prevented from being damaged.

なお、上述した第１の実施形態では、腕部１４ｃが保持ピース１４の前後に位置する二つの転動体９の中心Ｏ１，０２を通る直線Ｌ２より保持ピース１４の上側（例えば、転動体方向転換路の外周側）に位置するように、腕部１４ｃを保持ピース１４の左右側面部１４ｄ，１４ｅに設けた場合を例示したが、図６に示す第２の実施形態のように、腕部１４ｃが保持ピース１４の前後に位置する二つの転動体９の中心Ｏ１，０２を通る直線Ｌ２より保持ピース１４の下側（例えば、転動体方向転換路の内周側）に位置するように、腕部１４ｃを保持ピース１４の左右側面部１４ｄ，１４ｅに設けてもよい。   In the first embodiment described above, the arm portion 14c is above the holding piece 14 from the straight line L2 passing through the centers O1 and 02 of the two rolling elements 9 positioned before and after the holding piece 14 (for example, the rolling element direction change). The case where the arm portion 14c is provided on the left and right side surface portions 14d and 14e of the holding piece 14 so as to be located on the outer peripheral side of the road is illustrated, but as in the second embodiment shown in FIG. So that the arm is positioned below the holding piece 14 (for example, the inner peripheral side of the rolling element direction change path) with respect to the straight line L2 passing through the centers O1,02 of the two rolling elements 9 positioned before and after the holding piece 14. The portion 14c may be provided on the left and right side surface portions 14d and 14e of the holding piece 14.

また、図７に示す第３の実施形態のように、腕部１４ｃの中心線Ｌ１が保持ピース１４の前後に位置する二つの転動体９の中心Ｏ１，０２を通る直線Ｌ２と重なり合わないように、腕部１４ｃを保持ピース１４の左右側面部１４ｄ，１４ｅに設けても第１及び第２の実施形態と同様の効果を得ることができる。   Further, as in the third embodiment shown in FIG. 7, the center line L1 of the arm portion 14c does not overlap with the straight line L2 passing through the centers O1 and 02 of the two rolling elements 9 positioned in front of and behind the holding piece 14. In addition, even if the arm portion 14c is provided on the left and right side surface portions 14d and 14e of the holding piece 14, the same effect as in the first and second embodiments can be obtained.
