Claims (1)
- 内周に複列の外側転走面が形成された外方部材と、
一端部に車輪取付フランジを一体に有し、この車輪取付フランジから軸方向に延びる小径段部が形成されたハブ輪、
およびこのハブ輪の小径段部に圧入された内輪とからなり、外周に前記複列の外側転走面に対向する複列の内側転走面が形成された内方部材と、
この内方部材と前記外方部材の両転走面間に保持器を介して転動自在に収容された複列の転動体とを備え、
前記小径段部の端部を径方向外方に塑性変形させて形成した加締部により前記内輪が軸方向に固定された車輪用軸受装置において、
前記塑性変形前後の前記内輪の外径が測定され、この内輪外径の膨張量を以って、予め求められた関係に基き当該内輪に発生するフープ応力が管理され、このフープ応力が所定値以下に規制されると共に、軸力が前記内輪の押し込み量で規定されていることを特徴とする車輪用軸受装置。
