Description

この発明の目的は,上記の課題を解決することであり,外筒及びエンドリングを断面円形に形成し,外筒の内周面を円弧面からなる形状の軌道面に形成して軌道路での転動体の転動位置を安定させ,スライダに形成する複数の循環路について隣接する循環路を保持器の角部の軸方向中心を挟んで線対称に配置し,スライダに設けた循環路を構成する軌道路,リターン路及び方向転換路の軸回りでの配列を変更し,それによって循環路での転動体位置が安定して保持器にがたつきがなくなり,スライダのスムーズな安定した摺動運動となり,更に,内周面が多角形の外筒,外筒内に互いに係合して位置決め固定された転動体を保持する多角形の保持器,外筒の端部から突出した保持器の両端部に適正に位置決めして嵌合固定した一対のエンドリングから簡単な構造に構成し,保持器を外筒に容易に正確に嵌挿させて,保持器の両端部にエンドリングを的確に嵌合して回転方向と軸方向に互いに適正に位置決め固定させ,スライダの外周を外部に開放することなく,外部からの塵等の侵入を防止でき,保持器に長手方向に延びる外周凹溝を設けることによって保持器への外筒とエンドリングとの適正な位置決めと組み立てを容易に構成することから成るリニアブッシングを提供することである。 An object of the present invention is to solve the above-mentioned problems. The outer cylinder and the end ring are formed in a circular cross section, and the inner peripheral surface of the outer cylinder is formed in a raceway surface having a circular arc shape. The rolling positions of the rolling elements are stabilized, and adjacent circulation paths of a plurality of circulation paths formed on the slider are arranged symmetrically with respect to the axial center of the corner of the cage. raceways constituting, by changing the arrangement of the axis around the return passage and the direction changing passage, whereby the rolling element position in the circulation path there is no backlash in the stable retainer and smooth stable slider sliding In addition, the outer cylinder is a polygonal outer cylinder, the polygonal cage that holds the rolling elements that are engaged and fixed in the outer cylinder, and the cage that protrudes from the end of the outer cylinder. A pair of end points that are properly positioned and fitted to both ends of the The cage is constructed in a simple structure, the cage is easily and accurately inserted into the outer cylinder, and the end rings are accurately fitted to both ends of the cage to properly position and fix each other in the rotational and axial directions. The outer circumference of the slider can be prevented from entering the outside without opening the outer circumference of the slider, and the outer cylinder and end ring can be properly fitted to the cage by providing the outer circumferential groove extending in the longitudinal direction in the cage. To provide a linear bushing consisting of easy positioning and assembly.

この発明によるリニアブッシングは,上記のように構成されているので,簡素な形状の外筒への保持器の嵌挿が容易であって,保持器の両端部に外筒を挟んでエンドリングを容易に且つ正確に位置決め嵌合ができ,外筒,保持器及びエンドリングの組み立てを高精度に容易に行うことができ,リニアブッシングのコストダウンを実現することができる。特に,スライダに形成される複数の循環路について,隣接する循環路が保持器の角部の軸方向中心を挟んで線対称位置になるように配列されており,言い換えれば,スライダに設ける循環路を構成する軌道路,リターン路及び方向転換路の軸回りの配列を変更し,循環路での転動体位置を安定させ,結果的に保持器にがたつきが発生せず,保持器の構成がスムーズな摺動運動を提供する機能として作用し,スライダが軸上をスムーズな安定した相対往復摺動運動ができるようにすることができる。更に,外筒に形成した第2軌道面は,円弧面でR形状に形成されているので,第1軌道面と第2軌道面から成る軌道路を転動する前記転動体は,安定して周方向に振られる恐れがなく,ふらつかずに安定してスムーズに転動することができる。また,保持器の外周面には,エンドリングの嵌挿固定が容易に且つ適正に組み込みができる外周凹溝が長手方向全長にわたり形成されており,保持器に組み込まれたエンドリングが保持器の回転方向に位置決め固定され,また保持器にエンドリングを嵌挿して外筒が介在していない状態ではエンドリングが外周凹溝に沿って長手方向に移動可能になるが,エンドリング間に外筒を介在させることによって保持器に対する外筒の軸方向への位置決め固定が容易にでき,更にエンドリングの保持器への組み込み方向が限定されず,エンドリングを保持器のいずれ側の端部からでも組み込みができる構造に構成されており,また,エンドリングの内周面には保持器の外周面に密接して嵌合する内周凹溝の円弧面が嵌挿されており,保持器へのエンドリングの組み立てが適正に容易に行うことができ,組み立て時の自由度が増し,自動組立機を用いての大量生産も可能となる。 Since the linear bushing according to the present invention is configured as described above, it is easy to insert the cage into the outer cylinder having a simple shape, and end rings are sandwiched between both ends of the cage. Positioning and fitting can be performed easily and accurately, the outer cylinder, the cage and the end ring can be easily assembled with high accuracy, and the cost of the linear bushing can be reduced. In particular, the plurality of circulation paths formed on the slider are arranged so that adjacent circulation paths are in a line-symmetrical position with respect to the axial center of the corner of the cage, in other words, the circulation paths provided on the slider The arrangement around the axis of the track path, return path, and direction change path that composes the structure is stabilized, and the position of the rolling elements in the circulation path is stabilized. As a result, the cage does not rattle and the cage configuration Acts as a function to provide a smooth sliding movement, and the slider can perform a smooth and stable relative reciprocating sliding movement on the shaft. Furthermore, since the second raceway surface formed on the outer cylinder is formed in an R shape with an arcuate surface, the rolling element rolling on the raceway composed of the first raceway surface and the second raceway surface is stable. There is no fear of shaking in the circumferential direction, and it can roll stably and smoothly without wobbling. In addition, the outer circumferential surface of the cage is formed with an outer circumferential groove that can be easily and properly inserted and fixed in the end ring over the entire length in the longitudinal direction. When the end ring is positioned and fixed in the rotation direction and the end ring is inserted into the cage and no outer cylinder is interposed, the end ring can move in the longitudinal direction along the outer circumferential groove. The outer cylinder can be easily positioned and fixed in the axial direction with respect to the cage, and the direction in which the end ring is assembled into the cage is not limited, and the end ring can be mounted from either end of the cage. It is constructed so that it can be assembled, and the inner circumferential surface of the end ring is fitted with an arc surface of an inner circumferential groove that fits closely to the outer circumferential surface of the cage. End Ring of the assembly is properly can be easily performed, increases the degree of freedom at the time of assembly, it is possible mass production of using an automatic assembly machine.
