- 外周面に軸方向に沿ってボール転走溝が形成されたスプライン軸と、このスプライン軸が貫通する略円筒状に形成され、前記スプライン軸に対して多数のボールを介して組付けられると共に、前記ボールが循環するトラック溝を前記スプライン軸に面した内周面に有するナット部材とから構成され、
前記トラック溝は、スプライン軸のボール転走溝と対向して形成されて該ボールの負荷通路を形成する負荷直線溝と、この負荷直線溝と平行に設けられると共にスプライン軸の外周面に向けて開放された無負荷直線溝と、これら負荷直線溝と無負荷直線溝とを連通連結してこれらの間でボールを往来させると共に前記スプライン軸の外周面に開放された一対のボール偏向溝とから構成され、
前記ボール偏向溝は、前記スプライン軸のボール転走溝内を転動するボールの進行方向を強制的に変化させ、前記スプライン軸のプロファイルを利用してボールを前記ボール転走溝から離脱させる一方、離脱したボールを前記スプライン軸の外周面と協働して前記無負荷直線溝に誘導し、
前記スプライン軸のボール転走溝の一側には、前記ナット部材のボール偏向溝と対向する部位にボール誘導面が形成され、このボール誘導面はボール転走溝から滑らかに連続していることを特徴とするボールスプライン装置。 - 前記スプライン軸には2条が一対となった偶数条のボール転走溝が形成されて、各ボール転走溝はその長手方向と垂直な断面における形状がサーキュラアーク状をなしていることを特徴とする請求項1記載のボールスプライン装置。
- 前記ボール偏向溝内におけるボールの転動軌跡をナット部材の軸方向と垂直な断面に投影した軌跡は、かかるボール偏向溝と対向するスプライン軸のプロファイルと合致していることを特徴とする請求項1記載のボールスプライン装置。
- 前記ナット部材は、前記負荷直線溝及び無負荷直線溝が形成されたナット本体と、前記ボール偏向溝が形成されると共に前記ナット本体の軸方向の両端部に固定される一対のエンドキャップとから構成されることを特徴とする請求項1記載のボールスプライン装置。
- 前記ナット部材は単一部材からなり、その内周面に前記トラック溝が形成されていることを特徴とする請求項1記載のボールスプライン装置。
