前記スプライン軸の他方は円筒状に形成され内周面に前記円柱状のスプライン軸のスプライン歯と噛合するスプライン歯が設けられる軸連結構造において、
前記円柱状のスプライン連結部の先端面に円柱状のロケートピンが設けられ、前記円筒状の他方のスプライン軸の内周に円筒状のブッシュが設けられ、前記一対のスプライン軸はスプライン連結時に互いに密着して嵌り合うロケートピンとブッシュからなる軸ぶれ防止機構を備えていることを特徴とする軸連結構造。
(2)請求項2の軸連結構造は、一対のスプライン軸を嵌合させる際に、両スプライン軸の軸芯がずれている場合に、芯出しリングの先端面の外周縁に、芯出しピンの円錐部の傾斜面が接触して、該傾斜面でガイドされて芯出しリングが複数本の芯出しピンで構成される環状部内に導入される。そして、複数本の芯出しピンの円柱部の外周面が芯出しリングの外周面に係合して、両スプライン軸の軸芯を嵌合可能な範囲に一致させる。
(3)請求項3の軸連結構造は、前記フランジ部と芯出しリングの接触面にタクトスイッチ等を配置することにより、円柱部が芯出しリングの外周面に係合したことを容易に検出することができる。
(4)請求項4の軸連結構造は、供試体の回転軸と、該供試体の試験を行なう試験装置の回転軸とを、芯出しリングと複数本の芯出しピンで容易、且つ確実にスプライン連結することができる。
(5)請求項5の軸連結構造は、複数本の芯出しピンをピン駆動部材で供試体側に前進させて、複数の芯出しピンを芯出しリングの外周面に係合させて、両スプライン軸の軸芯を嵌合可能な範囲に一致させた後に、軸支持体を軸支持体駆動部材で供試体側に前進させて両スプライン軸を嵌合させることができる。
(6)請求項6の軸連結構造は、ピン駆動部材および軸支持体駆動部材にエアーシリンダを使用したので、サーボモータを使用する場合に較べて構造が簡単で安価に製造することができる。
(7)請求項7の軸連結構造は、ピン駆動部材および軸支持体駆動部材にエアーシリンダに代えてサーボモータ又は油圧シリンダを使用したので、芯出しピンや軸支持体の停止位置精度を向上させることができる。従って、験装置側のスプライン軸の先端と芯出しリングの底面部との間に隙間等を発生させることがエアーシリンダを使用した場合に較べて容易になる。
(8)請求項8の軸連結方法は、複数の芯出しピンをピン駆動部材で前進させて、これら芯出しピンを芯出しリングの外周面に接触させることにより両スプライン軸の軸芯を嵌合可能な範囲に一致させた後に、一方のスプライン軸を供試体側に前進させることにより、両スプライン軸を嵌合させることができる。
(9)請求項9の軸連結方法は、試験装置側のスプライン軸の先端と芯出しリングの底面部とを非接触状態にするとともに、芯出しピンと芯出しリングとを非接触状態にしたので、試験装置側のスプライン軸と芯出しリングの間および芯出しリングと芯出しピンとの間で摩擦抵抗を発生させることなくエンジンの試験を行なうことができる。
(10)請求項10の軸連結構造は、一対のスプライン軸を嵌め合わせると、これら一対のスプライン軸に設けたロケートピンとブッシュが嵌合、即ち隙間なく嵌り合って、軸ぶれ等の発生を防止する。
(11)請求項11の軸連結構造は、一対のスプライン軸を嵌め合わせると、前記一方のスプライン軸に設けたロケートピンが、前記他方のスプライン軸の内周に設けたブッシュ内に嵌合し、前記ロケートピンとブッシュを一体的に連結して、軸ぶれ等の発生を防止する。
(12)請求項12の軸連結構造は、前記ロケートピンの一部である大径軸部の外面を、前記ブッシュの一部である小内径部の内面に部分的に接触させる構成にしたので、該部の径精度や面精度を部分的に向上させることにより、大径軸部の外面と、前記ブッシュの内面を密着させて、軸ぶれ等の発生を防止することができる。従って、ロケートピンの外面とブッシュの内面の全域を均等に接触させる場合に比べて接触面の加工が容易になる。
(13)請求項13の軸連結構造は、前記ロケートピンの大径軸部及び/又はブッシュの小内径部の先端部に設けた挿入ガイド面によって、ロケートピンとブッシュの嵌合を円滑に行うことができる。
(14)請求項14の軸連結構造は、前記ロケートピン及び/又は前記ブッシュを必要に応じて取り付け、取り外すことができ、部品の修理や交換を容易に行うことができる。
(15)請求項15の軸連結構造は、エンジン等の供試体の回転軸と、該供試体の試験を行なうダイナモメータの回転軸とを連結するのに用いたので、エンジン等の供試体の性能試験を軸ぶれや共振の発生を抑えた状態で行うことができる。
(16)請求項16の軸連結構造は、ロケートピンとブッシュの嵌合時において、ロケートピンと接触するブッシュの小内径部の内周面を、一対のベアリングの内側に位置させることで、軸ぶれをより少なくすることができる。
(17)請求項17の軸連結構造は、軸ぶれや共振が発生する可能性が高くなるフローティングタイプの軸支持体を使用した場合においても、軸ぶれや共振の発生をより確実に防止することができる。
(18)請求項18の軸連結構造は、ロケートピンを、合成樹脂やゴムの自己潤滑性や弾力性のある材質で形成したので、金属製のものと比較してより円滑に嵌合できるという効果がある。
(19)請求項19の軸連結構造は、雄,雌のスプライン軸を嵌め合わせると、これら雄,雌のスプライン軸に設けたロケートピンとブッシュが嵌合、即ち隙間なく嵌り合って、軸ぶれ等の発生を防止する。
(1)スプライン軸104とスプライン軸107を嵌合させると、これらスプライン軸104のスプライン溝とスプライン軸107のスプライン溝との間に存在する間隙(遊び)によって軸ぶれ等が発生する。この間隙は、スプライン軸104とスプライン軸107を円滑に嵌合させるために必要不可欠なものであり、前記間隙を大きくすればするほど、スプライン軸104とスプライン軸107の嵌合は容易になる反面、軸ぶれ(ガタ)も増大する。特に、スプライン連結しているモータやエンジン等の回転体がラバーマウント部材のような弾性体を介して固定される場合には、供試体の軸位置が不安定又は変化することになり、雄,雌のスプライン軸104,107の嵌め合い誤差を原因とする振動や共振の発生という問題があった。この理由は、スプライン連結では、回転軸方向の力を伝えるだけで、軸と直角方向の固定は、スプライン連結の嵌め合い誤差があるため、十分に固定できないためである。特に、ダイナモメータ側のスプライン軸107を支持している軸支持体108が例えば特許文献3に示すフローティング軸受けの場合には、軸ぶれや共振が発生しやすくなる。
(2)前記(1)とは逆に、前記間隙を小さくすればするほど軸ぶれを抑制できるがスプライン軸104とスプライン軸107の嵌合が難しくなる。前記間隙を小さくせずに、軸ぶれ等を抑制する方法として、スプライン軸の嵌め合い長さを長くして、間隙を小さくし、軸と直角方向の固定をより強固にする方法も考えられるが、結合軸の長さが長くなり、さらに、図15の軸支持体駆動機構109のストローク量が必要となるため、装置全体が大型化するという問題がある。
