Description
【０００１】[0001]
本考案はスプライン継手に関するものである。 The present invention relates to a spline joint.
【０００２】[0002]
タービンエンジン等の駆動トルクを測定する際には、トルク測定を行うべきエ ンジンをテストベンチに取り付け、前記エンジンの出力軸をダイナモメータの入 力軸に継手を介して連結し、該ダイナモメータによって前記エンジンのトルクを 測定するようにしているが、前記エンジンの出力軸とダイナモメータの入力軸の 軸心は、エンジンをテストベンチに取り付ける際にエンジンの取り付け位置を微 調整しても完全に同軸にすることが容易でない。 When measuring the drive torque of a turbine engine, etc., an engine on which the torque should be measured is attached to the test bench, the output shaft of the engine is connected to the input shaft of the dynamometer via a joint, and the dynamometer is used. Although the torque of the engine is measured, the axes of the output shaft of the engine and the input shaft of the dynamometer are completely coaxial even if the engine mounting position is finely adjusted when mounting the engine on the test bench. Not easy to do.
【０００３】 このため、前記エンジンの出力軸とダイナモメータの入力軸とが完全に同軸で ない状態で、エンジンの出力軸とダイナモメータの入力軸を連結する手段にスプ ライン継手等の自在継手を用いる。Therefore, in a state where the output shaft of the engine and the input shaft of the dynamometer are not completely coaxial, a universal joint such as a spline joint is connected to the means for connecting the output shaft of the engine and the input shaft of the dynamometer. To use.
【０００４】 しかし、スプライン継手を用いた場合には、スプラインキーやスプラインキー 溝に摩耗が生じ、また、他の自在継手を用いた場合においても回転力伝達面等に 摩耗が生じる。However, when the spline joint is used, the spline key and the spline key groove are worn, and when other universal joints are used, the rotational force transmitting surface and the like are also worn.
【０００５】 そこで、従来は、エンジンの出力軸とダイナモメータの入力軸の連結手段に、 継手を構成する部材の弾性を積極的に利用するようにしたトーマスカップリング 等の弾性継手を用い、該弾性継手によりエンジンの出力軸とダイナモメータの入 力軸を連結するようにして、エンジンの出力軸とダイナモメータの入力軸の軸心 のずれに対処している。Therefore, conventionally, an elastic joint such as a Thomas coupling that positively utilizes the elasticity of the members forming the joint is used as a connecting means between the output shaft of the engine and the input shaft of the dynamometer, and The output shaft of the engine and the input shaft of the dynamometer are connected by an elastic joint to prevent the misalignment of the engine output shaft and the input shaft of the dynamometer.
【０００６】[0006]
ところが、エンジンの出力軸とダイナモメータの入力軸を連結する手段に上述 した弾性継手を用いると、該弾性継手の弾性力の影響を受けてダイナモメータに より測定されるエンジントルクの実測値が計算上のエンジントルクとは異なった 値になるので、測定されたエンジントルクの実測値を補正する必要があった。 However, if the elastic joint described above is used as a means for connecting the output shaft of the engine and the input shaft of the dynamometer, the measured value of the engine torque measured by the dynamometer is calculated under the influence of the elastic force of the elastic joint. Since the value is different from the above engine torque, it was necessary to correct the measured value of the measured engine torque.
【０００７】 一方、中空構造を有し且つ中空部内に潤滑油を流通させてスプラインキーとス プラインキー溝との間に潤滑油を供給するようにした構造のスプライン継手もあ るが、該スプライン継手を前記エンジンの出力軸とダイナモメータの入力軸の連 結手段に用いるとすると、軸中空部に潤滑油を流通させる構造であるため、潤滑 油の自由液面に起因する自励振動が発生し、ダイナモメータの測定値に影響がで ることが予想される。On the other hand, there is also a spline joint having a hollow structure in which the lubricating oil is circulated in the hollow portion to supply the lubricating oil between the spline key and the spline key groove. If a joint is used as a connecting means between the output shaft of the engine and the input shaft of the dynamometer, the structure in which the lubricating oil is circulated in the hollow part of the shaft causes self-excited vibration due to the free liquid surface of the lubricating oil. However, it is expected that the measured value of the dynamometer will be affected.
【０００８】 本考案は、上述の実情に鑑みてなしたもので、自励振動を発生させることなく 、出力軸と入力軸の軸心のずれに起因するスプラインキー及びスプラインキー溝 の摩耗を抑止することが可能なスプライン継手を提供することを目的としている 。The present invention has been made in view of the above circumstances, and suppresses wear of the spline key and the spline key groove due to the deviation of the shaft center of the output shaft and the input shaft without generating self-excited vibration. The purpose of the present invention is to provide a spline joint that can be used.

【００２０】 以下、本実施例の作動を説明する。The operation of this embodiment will be described below.
【００２１】 エンジンの出力軸（図示せず）により該出力軸に連結された第１の軸１が回転 すると、その回転力は、スプラインキー溝５とスプラインキー１０の噛合によっ てダイナモメータの入力軸（図示せず）に連結された第２の軸９に伝達される。When the first shaft 1 connected to the output shaft of the engine (not shown) is rotated, the rotational force is generated by the engagement of the spline key groove 5 and the spline key 10 of the dynamometer. It is transmitted to the second shaft 9 connected to the input shaft (not shown).
【００２２】 このとき、潤滑油供給管１２によって連結部３の後方Ｂ側の面へ潤滑油を噴射 すると、該潤滑油は遠心力により、連結部３の後方Ｂ側の面に沿い外嵌部４の内 周面に向って流れ、潤滑油流通溝８へ流入する。At this time, when the lubricating oil is supplied to the rear B-side surface of the connecting portion 3 by the lubricating oil supply pipe 12, the lubricating oil is centrifugally applied to the rear B-side surface of the connecting portion 3 to fit the outer fitting portion.
