Claims (3)
- 軸方向両端に径方向内向きの鍔部を設け、一方の鍔部をころ軌道部の肉厚と略同じ肉厚にし、他方の鍔部をころ軌道部よりも薄い肉厚としたシェル形の外輪と、この外輪の内周に組み込まれる複数のころとを備えたシェル形総ころ軸受であって、
該ころ軌道部と略同じ肉厚の鍔部を、軸方向内側に向くよう径方向に沿う面に対し所定角度傾くテーパ形状とし、この鍔部の内周部分の外側面および内側面を径方向に沿う平坦面形状に形成したことを特徴とするシェル形総ころ軸受。 - ころを、その端面が平坦な形状とした、ことを特徴とする請求項1に記載のシェル形総ころ軸受。
- 軸方向両端に径方向内向きの鍔部を設け、一方の鍔部をころ軌道部の肉厚と略同じ肉厚にし、他方の鍔部をころ軌道部よりも薄い肉厚としたシェル形の外輪を有するシェル形総ころ軸受の前記外輪を製造する方法であって、
有底の円筒部材の底部を絞り加工することにより該底部の中央領域を軸方向内側に凹ませて、該底部の付け根側領域を軸方向内側に向くように径方向に沿う面に対し所定角度傾くテーパ形状とするとともに該底部の中央領域の内側面と外側面とを径方向に沿う平坦面形状とする工程と、
該有底の円筒部材の底部外周を円筒形の受け金型の上端面で受けさせた状態で該底部の中央領域を円形に打ち抜くことにより、該底部の付け根側領域をテーパ形状の鍔部として残すとともに、この鍔部の内周部分に該底部の中央領域の径方向に沿う平坦な外側面および内側面を残す工程とを有し、
前記底部の打ち抜き工程で用いる円筒形の受け金型は、その上端面の径方向途中領域に底部の付け根側領域を受けるテーパ面を有し、該上端面において前記テーパ面の内周領域に底部の平坦な中央領域において前記付け根側領域の近傍を受ける平坦面を有していることを特徴とするシェル形総ころ軸受の外輪の製造方法。
