Description
このうちのハブ本体は、軸方向中間部外周面に軸方向片側の内輪軌道を有する。
又、前記内輪は、外周面に軸方向他側の内輪軌道を有し、このハブ本体の軸方向他端寄り部分に外嵌している。
そして、前記ハブ本体の軸方向他端部に設けた円筒部を径方向外方に塑性変形させる事で形成したかしめ部により、前記内輪の軸方向他端面を抑え付けてこの内輪を前記ハブ本体に支持固定している。又、前記かしめ部の軸方向他端面に、円周方向に関する凹凸部であるハブ側フェイススプラインを形成している。
上述の様な本発明の製造方法の対象となる転がり軸受ユニットは、より具体的には、内周面に複列の外輪軌道を有する外輪と、これら両外輪軌道と前記両内輪軌道との間に、それぞれ複数個ずつ転動自在に設けられた転動体とを更に備える。
又、本発明の転がり軸受ユニットの製造方法は、前記ハブ本体の中心軸に対し傾斜した、自身の中心軸を中心とする回転(自転)を可能に支持されて、先端面を、凹部と凸部とを全周に亙って交互に配置して成る加工面としたロールの加工面を、前記かしめ部の軸方向他端面に向けて押し付けた状態で、このロールを、前記ハブ本体の中心軸を中心として回転させる揺動鍛造を施す事により、円周方向に関する凹凸部であるハブ側フェイススプラインを形成する。
換言すれば、前記間隔を、前記凹部と凸部とのうちの一方の中央位置を通り、前記ロールの中心軸と平行な仮想線が、前記ハブ本体の中心軸とこのロールの中心軸とを含む仮想平面内に存在する状態で最も小さく、同じく他方の中央位置を通り、前記ロールの中心軸と平行な仮想線が、前記ハブ本体の中心軸とこのロールの中心軸とを含む仮想平面内に存在する状態で最も大きくなる様に周期的に変化させる。
上述の様な本発明の転がり軸受ユニットを実施する場合に、具体的には、例えば、前記ステージを、前記ハブ本体の軸方向に関して周期的に往復運動させる。
この場合に好ましくは、前記ハブ本体の中心軸に対する前記ロールの中心軸の傾斜角度を30度以下とする。
