Description

【0001】
【発明の属する技術分野】
本発明は、無段変速機用プ−リ−軸受の摩耗を試験する装置に関する。
【0002】
【従来の技術】
従来、無段変速機用プ−リ−軸受の摩耗を試験する摩耗試験装置として、図6に示すようなものがある。
図6に示すように、外力により回転される回転軸51にプ−リ−軸相当材52が取り付けられている。また、ハウジング53の内周部には摩耗試験されるプ−リ−軸受54が圧入され、プ−リ−軸受54の内周部にプ−リ−軸相当材52が嵌められる。尚、図7は、図6のA−A矢視断面図である。
【0003】
図6、図7に示すように、ハウジング53に対して矢印の方向に荷重を負荷することで、プ−リ−軸相当材52とプ−リ−軸受54間にラジアル荷重(軸間力)が発生する。
この状態で回転軸51を回転させることによりプ−リ−軸相当材52は回転するが、ハウジング53及びプ−リ−軸受54は回転しない。
尚、プ−リ−軸相当材52の回転に伴ってハウジング53及びプ−リ−軸受54がプ−リ−軸相当材52から抜けないように、プ−リ−軸相当材52に止め輪55が嵌められている。
【0004】
このように構成された従来の無段変速機用プ−リ−軸受の摩耗試験装置において、回転軸51を回転させ、プ−リ−軸相当材52を回転させることにより、プ−リ−軸受54の摩耗を試験している。
【0005】
【発明が解決しようとする課題】
上記従来の無段変速機用プ−リ−軸受の摩耗試験装置によれば、プ−リ−軸受54は常に同じ部分(図7で接触部として示している部分)でプ−リ−軸相当材52と接触している。そのため、従来の無段変速機用プ−リ−軸受の摩耗試験装置は、実際の無段変速機のプ−リ−軸受の使用状態と異なるので、実際の無段変速機と従来の摩耗試験装置におけるプ−リ−軸受の摩耗形態及び摩耗量の相関をとることができないという問題がある。
そこで本発明では、実際の無段変速機のプ−リ−軸受の使用状態と同じ状態でプ−リ−軸受の摩耗試験を行うことにより、実際の無段変速機のプ−リ−軸受の摩耗形態及び摩耗量と相関をとることが可能な無段変速機用プ−リ−軸受の摩耗試験装置を提供することを解決すべき課題とするものである。
【0006】
【課題を解決するための手段】
上記の課題を解決するため、無段変速機用プ−リ−軸受の摩耗試験装置、外力により回転される入力側軸に入力側プ−リ−軸受を介して入力側プ−リ−が取り付けられた入力部を構成する一方、前記入力側プ−リ−と回転伝達手段を介して連結される出力側プ−リ−が出力側プ−リ−軸受を介して出力側軸に取り付けられた出力部を構成し、更に、前記出力側軸を前記入力側軸に対して離間する方向に移動させることで前記入力側軸と前記入力側プ−リ−軸受との間及び前記出力側軸と前記出力側プ−リ−軸受との間に作用する軸間力を調整する軸間力調整手段を設けことである。
また、前記軸間力調整手段は、前記出力側軸をベアリングを介して軸支するベアリングホルダ−と該ベアリングホルダ−を前記出力軸とは直角の方向に移動させるテンションボルト及びナットとから構成され、該ナットを締め付けることで前記入力側軸と前記入力側プ−リ−軸受との間及び前記出力側軸と前記出力側プ−リ−軸受との間に作用する軸間力を調整する手段であることである。
【0007】
上記無段変速機用プ−リ−軸受の摩耗試験装置によれば、軸間力調整手段により軸間力を実際の無段変速機の軸間力と同様の値になるように調整し、更に、モ−タ等の外力により入力部と出力部とを実際の無段変速機の回転数に応じた回転数で回転させることにより、入力側及び出力側プ−リ−軸受の摩耗状態を試験する。
この試験状態において、実際の無段変速機と同様に入力側軸と入力側プ−リ−軸受、及び出力側軸と出力側プ−リ−軸受は、1回転中、違う部分が接触するため、入力側及び出力側プ−リ−軸受の摩耗状態が正確に試験される。
【0008】
【発明の実施の形態】
次に、本発明の実施の形態について図面を参照しながら説明する。
図1は、無段変速機用プ−リ−軸受の摩耗試験装置1の全体的な構成を示した平面断面図であり、図2は、この摩耗試験装置1の側面図である。
尚、図5は、実際の無段変速機におけるプ−リ−軸受の使用状態を示したもので、図5に示すように、実際の無段変速機におけるプ−リ−軸受40の外周面は可動プ−リ−42の内周面に圧入され、プ−リ−軸受40の内周面は固定プ−リ−41の軸部41Aの外周面と嵌合されており、固定プ−リ−41に対する可動プ−リ−42の位置により、Vベルト43を介して回転される図示していない従動側プ−リ−が無段階に変速されるように構成されている。
【0009】
図1に示すように、無段変速機用プ−リ−軸受の摩耗試験装置1は、駆動源となる可変速モ−タ−2のシャフト2Aがフランジ3A,3Bを介して入力側軸4に連結されている。この入力側軸4は、両端部が、テ−ブル(機台)5の上面に固定された入力側ステイ6A,6Bに取着のベアリング7A,7Bに軸支されており、可変速モ−タ−2の回転駆動により回転される。フランジ3A,3Bはボルト8A,8Bを用いて結合され、更にフランジ3Bの回転を入力側軸4に伝えるため、キ−9が嵌められている。また、入力側軸4の左端部にはネジ4Aが形成されており、このネジ4Aに対して平ワッシャ10とナット11を用いてフランジ3Bと入力側軸4とが結合されている。
【0010】
前記プ−リ−軸受40に相当する入力側プ−リ−軸受12A,12Bの外周面は入力側プ−リ−13の内周面に圧入され、入力側プ−リ−軸受12A,12Bの内周面は前記固定プ−リ−41の軸部41Aに相当する入力側軸4の外周面と嵌合されている。そして、入力側軸4と入力側プ−リ−13との間にキ−14を嵌めることにより入力側軸4の回転が入力側プ−リ−13に伝達される。尚、入力側プ−リ−13が入力側軸4の軸方向に移動しないように止め輪14A,14Bが入力側軸4の外周面に嵌められている。
【0011】
一方、テ−ブル(機台)5の上面に固定された出力側ステイ16A,16Bにはベアリングホルダ−17A,17Bが取り付けられており、ベアリングホルダ−17A,17Bにはベアリング18A,18Bが取り付けられている。そのベアリング18A,18Bには出力側軸19が軸支されている。また、ベアリングホルダ−17A,17Bは、出力側軸19と直角の方向に移動可能に出力側ステイ16A,16Bに嵌着されている。
【0012】
前記プ−リ−軸受40に相当する出力側プ−リ−軸受21A,21Bの外周面は出力側プ−リ−22の内周面に圧入され、出力側プ−リ−軸受21A,21Bの内周面は前記出力側軸19の外周面と嵌合されている。この出力側プ−リ−22は、前述の入力側軸4の回転がベルト23を介して伝達されるため回転される。そして、出力側軸19と出力側プ−リ−22との間にキ−24を嵌めることにより出力側プ−リ−22の回転が出力側軸19に伝達される。
尚、出力側プ−リ−22が出力側軸19の軸方向に移動しないように止め輪25A,25Bが出力側軸19の外周面に嵌められている。
【0013】
前記ベアリングホルダ−17A,17Bにはテンションボルト26A,26Bの先端部が出力側軸19と直角の方向に取り付けられている。そしてテンションボルト26A,26Bの基端部はネジが切られており、出力側ステイ16A,16Bの外周面に接したナット27A,27Bに螺合されている。従って、ナット27A,27Bを締め付けることによって、前記ベルト23に張力を与え、前記入力側軸4、出力側軸19それぞれにおいて、入力側プ−リ−軸受12A,12B、及び出力側プ−リ−軸受21A,21Bとの間に軸間力を発生させることができる。
【0014】
テンションボルト26A,26Bには、歪みゲ−ジ31A,31Bが貼り付けられており、この部分における歪みを検出するようになっている。歪みゲ−ジ31A,31Bは、リ−ド線32A,32Bを介してストレインアンプ33に接続されている。そしてストレインアンプ33で増幅された歪み検知信号をレコ−ダ−34に導いて表示及び記録させる。
【0015】
以上のように構成された無段変速機用プ−リ−軸受の摩耗試験装置1を用いて入力側プ−リ−軸受12A,12B、及び出力側プ−リ−軸受21A,21Bの摩耗試験を行うとき、最初、可変速モ−タ−2の回転数を、実際の無段変速機の回転数と同じ回転数になるように調整する。この回転により、入力側軸4、入力側プ−リ−13、入力側プ−リ−軸受12A,12Bから成る入力部と、出力側軸19、出力側プ−リ−22、出力側プ−リ−軸受21A,21Bから成る出力部とが同時に回転する。また、レコ−ダ−34のデ−タを見ながらテンションボルト26A,26Bにおける荷重が実際の無段変速機の軸間力と同じ値になるようにナット27A,27Bの締め付けを行う。
尚、この状態で、図3に示すように、入力側軸4、出力側軸19は、それぞれの外周面と、入力側プ−リ−軸受12A,12B、出力側プ−リ−軸受21A,21Bの内径面との間に微小な隙間ができる一方、1回転中、違う部分が接触することになる。
【0016】
上記摩耗試験において、図4に示すように、入力側プ−リ−軸受12A,12B、出力側プ−リ−軸受21A,21Bと、ベルト23との位置関係を実際の無段変速機と同じ(L1 ,L2 の位置)にすることで、実際の無段変速機と同様の荷重(F1 +F2 =F)、即ち軸間力を入力側プ−リ−軸受12A,12B、出力側プ−リ−軸受21A,21Bで受ける。この際、荷重F1 と荷重F2 は、一般に異なった大きさである。
【0017】
また、入力側軸4、出力側軸19それぞれの表面粗度、硬度、表面処理等を適宜変更し、プ−リ−軸受とのベストマッチングを選定することができる。そのプ−リ−軸受とのベストマッチングデ−タにより実際の無段変速機に使用したときのプ−リ−軸受の摩耗デ−タを得ることができる。また、同様にプ−リ−軸受を変更した場合も、実際の無段変速機に使用したときのプ−リ−軸受の摩耗デ−タを得ることができる。
更に、入力側プ−リ−13、出力側プ−リ−22の直径を変えることにより、プ−リ−比を変えて、入力側プ−リ−軸受12A,12B、出力側プ−リ−軸受21A,21Bの摩耗試験をすることができる。
【0018】
【発明の効果】
以上のように本発明によれば、実際の無段変速機のプ−リ−軸受の使用状態と同じ状態でプ−リ−軸受の摩耗試験を行うことができるため、実際の無段変速機のプ−リ−軸受の摩耗形態及び摩耗量と相関を取ることができるという効果がある。

The input-flop - Li - an output side flop is connected via the rotation transmitting means - Li - is the output flop - Li - constitutes the output portion attached to the output side shaft via a bearing,
Further, by moving the output side shaft in a direction away from the input side shaft, the output side shaft and the output side pulley are positioned between the input side shaft and the input side pulley bearing. - CVT-flop, characterized in that a shaft force adjusting means for adjusting the axial force acting between the bearing - Li - wear testing device of the bearing.
前記軸間力調整手段は、前記出力側軸をベアリングを介して軸支するベアリングホルダ−と該ベアリングホルダ−を前記出力軸とは直角の方向に移動させるテンションボルト及びナットとから構成され、該ナットを締め付けることで前記入力側軸と前記入力側プ−リ−軸受との間及び前記出力側軸と前記出力側プ−リ−軸受との間に作用する軸間力を調整する手段である請求項1に記載の無段変速機用プ−リ−軸受の摩耗試験装置。The inter-axis force adjusting means includes a bearing holder that supports the output side shaft via a bearing, and a tension bolt and a nut that move the bearing holder in a direction perpendicular to the output shaft. A means for adjusting an interaxial force acting between the input side shaft and the input side pulley bearing and between the output side shaft and the output side pulley bearing by tightening a nut. The wear test apparatus for a pulley bearing for continuously variable transmission according to claim 1.
