Description
本発明にかかる転がり軸受装置の外輪部材の製造方法は、外周に径方向外向きに延びるフランジが設けられ、前記フランジの円周方向の複数箇所にナックルとの固定に用いるねじ孔が軸方向に設けられた転がり軸受装置の外輪部材の製造方法であって、前記フランジの一側面が径方向に沿ってほぼ平坦に形成されるとともに、前記フランジの他側面の付け根側に、前記ねじ孔の中心を結ぶ円の近傍から前記外輪部材の外周面へ向けて形成された斜面と、この斜面の前記ねじ孔に対応する部分に形成され前記ねじ孔を作るドリルの刃先の干渉を避けるため前記フランジの他側面に形成された平坦面とこの平坦面から外輪部材の外周面にかけて曲面でつながる微小肉盛り部とを備えた凹部とを鍛造により形成した後、前記凹部の前記平坦面に前記ねじ孔を開口するためのドリルの先端を接触させ、前記フランジの他側面側から前記ねじ孔を形成することを特徴としている。

- 外周に径方向外向きに延びるフランジを有し、前記フランジの円周方向の複数箇所にナックルとの固定に用いるねじ孔が軸方向に設けられているとともに鍛造で一体に成形された転がり軸受装置の外輪部材であって、
前記フランジの一側面が径方向に沿ってほぼ平坦に形成されており、
前記フランジの他側面の付け根側に、前記ねじ孔の中心を結ぶ円の近傍から前記外輪部材の外周面へ向けて斜面が設けられ、この斜面の前記ねじ孔に対応する部分に、前記ねじ孔を作るドリルの刃先の干渉を回避するための凹部を設け、
この凹部において前記ねじ孔が開口している軸方向他方側に面することになる底部の前記ねじ孔の周縁部から外輪部材の外周面にかけて曲面でつながる微小肉盛り部が形成されたことを特徴とする転がり軸受装置の外輪部材。 - 外周に径方向外向きに延びるフランジが設けられ、前記フランジの円周方向の複数箇所にナックルとの固定に用いるねじ孔が軸方向に設けられた転がり軸受装置の外輪部材の製造方法であって、
前記フランジの一側面が径方向に沿ってほぼ平坦に形成されるとともに、
前記フランジの他側面の付け根側に、前記ねじ孔の中心を結ぶ円の近傍から前記外輪部材の外周面へ向けて形成された斜面と、この斜面の前記ねじ孔に対応する部分に形成され前記ねじ孔を作るドリルの刃先の干渉を避けるため前記フランジの他側面に形成された平坦面とこの平坦面から外輪部材の外周面にかけて曲面でつながる微小肉盛り部とを備えた凹部とを鍛造により形成した後、
前記凹部の前記平坦面に前記ねじ孔を開口するためのドリルの先端を接触させ、前記フランジの他側面側から前記ねじ孔を形成することを特徴とする転がり軸受装置の外輪部材の製造方法。
