Abstract
【解決手段】トラック溝30を有するカップ部12と、カップ部12の底部に形成された軸部13とを別部材で構成し、カップ部12を形成するカップ部材12aと軸部13を形成する軸部材13aとを溶接してなる外側継手部材11の製造方法。中炭素鋼で形成したカップ部材12aを鍛造加工により一体に形成した後、機械加工で接合用端面51を形成したカップ部材12aを準備し、機械加工でカップ部材12aの底部12a2と接合される接合用端面51を形成した軸部材13aを準備し、カップ部材12aの接合用端面50と軸部材13aの接合用端面51を突合せて、半径方向にビームを照射して溶接する。カップ部材12aの接合用端面50の外径をジョイントサイズ毎に同一寸法とし、溶接後、一方の接合用端面を有する部材の表面側から超音波探傷検査を行う。

Description
バー材)を鍛造加工やしごき加工等の塑性加工、切削加工、熱処理、研削加工等を施すことによって、カップ部と軸部とを一体成形する場合が多い。
(1)レーザ溶接や電子ビーム溶接における生産技術の面では、カップ部材と軸部材を密閉空間に設置して真空引きし、中空空洞部も真空化された状態で溶接することで溶融物の吹き上がりや気泡の発生が抑えられる。
(2)また、生産性の面では、生産性向上を図るために焼入れ焼戻しの熱処理を施したカップ部材と軸部材を溶接する場合、溶接時の熱で周辺部の温度が上昇し、熱処理部の硬度が低下する懸念がある。この問題に対しては、溶接工程の順序の入れ替えにより、継手機能への影響がない範囲で最も効率的でコスト低減が可能な工程で接合するという方法に着目した。例えば、溶接時の熱影響がないものであれば、焼入れ焼戻しの熱処理を施した完成状態のカップ部材と軸部材を溶接し、一方、熱影響があるものは、溶接後の熱処理とする工程など、カップ部材や軸部材の形状、仕様等に応じて最適な工程をとるコンセプトを見出した。
(3)さらに、生産性や品種統合の面では、図29〜31に示すカップ部材72には、次のような問題があることが判明した。すなわち、カップ部材72は、鍛造加工等によりカップ部の底部より縮径された短軸部が形成されるが、この短軸部が軸部材73の形状、寸法を基準にして設定され、軸部の途中位置で接合される構成となっている。軸部材73は、組み付けられる車両によって、標準的な長さのステムやロングステムというタイプの違いに加えて、種々の軸径や外周形状が要求される。このため、カップ部材72の短軸部を軸部材73の形状、寸法を基準にして設定し、軸部の途中位置で接合する場合、軸部材73と接合されるカップ部材72の短軸部の軸径(接合径)や形状、長さ(接合位置)の両方が異なるため、一種類の軸部材73に対して専用のカップ部材72が必要になる。したがって、生産性の向上やカップ部材の品種統合によるコスト低減の面でも問題があることが判明した。
(4)加えて、自動車用等の量産製品である等速自在継手の外側継手部材の新たな製造コンセプトを実用面で成立させるためには、溶接部の検査精度および検査作業性の向上を可能にする超音波探傷検査の方法や溶接部形状に工夫が必要であることが判明した。
鍛造重量に基づいてバー材を所定長さで切断し、ビレットを製作する。
ビレットを鍛造加工により、カップ部材12aの素形材として筒状部、底部および凸部を一体成形する。
前記素形材のトラック溝30および筒状内周面42をしごき加工して、カップ部材12aの筒状部の内周を仕上げる。
しごき加工後の素形材に、外周面、ブーツ取付溝32、止め輪溝33、接合用端面50等を旋削加工する。本実施形態では、旋削加工工程S4cの後、中間部品としてのカップ部材12aに品番を付与して管理する。
[バー材切断工程S1s]
軸部全長に基づいてバー材を所定長さで切断し、ビレットを製作する。その後、軸部材13aの形状に応じて、ビレットをアプセット鍛造により概略形状に鍛造加工する場合もある。
ビレットの外周面(軸受装着面14、止め輪溝15、スプライン下径、端面など)とカップ部材12a側端部の接合用端面51、溶接深さ確認用チャンファ51aなどを旋削加工する。
旋削加工後の軸部材にスプラインを転造加工する。ただし、スプラインの加工は転造加工に限られるものではなく、適宜プレス加工等に置き換えることもできる。本実施形態では、スプライン加工後、中間部品としての軸部材13aに品番を付与して管理する。
カップ部材12aの接合用端面50と軸部材13aの接合用端面51を突合せて溶接する。
カップ部材12aと軸部材13aの溶接部49を超音波探傷方法により検査する。
溶接後のカップ部12の少なくともトラック溝30、筒状内周面42および軸部13の外周の必要範囲に熱処理として高周波焼入れ焼戻しを行う。溶接部は熱処理を施さない。カップ部12のトラック溝30や筒状内周面42はHRC58〜62程度の硬化層が形成される。また、軸部13の外周の所定範囲にHRC50〜62程度の硬化層が形成される。
熱処理後、軸部13の軸受装着面14等を研削加工して仕上げる。これにより、外側継手部材11が完成する。
