Description

この発明によるボールスプラインは、スプライン軌道が設けられた軸と、ボールを介して軸に嵌め合わされたボールスプライン外筒とを備え、ボールスプライン外筒は、軸のスプライン軌道に対向させられることで主通路を構成するスプライン軌道が形成された略円筒状の外筒本体と、戻し通路が形成されておりかつ外筒本体の内周に嵌め合わされた略円筒状の保持器本体と、保持器本体の戻し通路と主通路とを連通する連通路が形成されており保持器本体に一端側から突き合わされた保持器蓋とを有しているボールスプラインにおいて、保持器本体および保持器蓋は、互いに突き合わされて、その両端面に配置された１対の止め輪によって外筒本体に支持されており、保持器本体の端面および保持器蓋の端面の少なくとも一方に、軸方向に突出する凸部が周方向に所定間隔で３カ所以上形成されており、保持器本体と保持器蓋とは、軸方向の弾性的な与圧が付加されて組み付けられていることを特徴とするものである。 A ball spline according to the present invention includes a shaft provided with a spline track, and a ball spline outer tube fitted to the shaft via a ball. A substantially cylindrical outer cylinder main body formed with a spline track constituting a passage; a substantially cylindrical cage main body formed with a return passage and fitted to the inner periphery of the outer cylinder main body; In a ball spline having a communication passage that connects the return passage and the main passage, and having a cage lid that is abutted against the cage body from one end side, the cage body and the cage lid protrude from each other. And is supported by the outer cylinder main body by a pair of retaining rings disposed on both end faces thereof, and is axially provided on at least one of the end face of the cage body and the end face of the cage lid. Convex portion out are formed three or more locations at predetermined intervals in the circumferential direction, and the holder body and the retainer lid, characterized in that the elastic preload in the axial direction are assembled is added Is.
