Abstract

PROBLEM TO BE SOLVED: To provide a spline connection structure capable of surely preventing runout or the like of shafts without increasing the length of a spline shaft and without reducing intervals which makes the engagement difficult.SOLUTION: In this spline connection structure 1, a male and a female spline connecting parts 4 and 5 are provided in an end of a rotary shaft 2 of a pair of rotary shafts 2 and 3 to be connected to each other and an end of the other rotary shaft 3, and these male and female spline connecting parts 4 and 5 are engaged with each other to connect the pair of rotary shafts 2 and 3. The male and the female spline connecting parts 4 and 5 respectively include a locate pin 6 and a bush 7 to be engaged with each other in spline connection.

Description

本発明は、スプラインを使用して一対の回転軸を連結するスプライン連結構造に関するものである。   The present invention relates to a spline coupling structure that couples a pair of rotating shafts using a spline.

回転軸相互を連結する場合、例えば、エンジン単体試験をする際にエンジン等の供試体の回転軸とダイナモメータの回転軸をスプライン連結する場合においては、図７に示すように、架台１０１上にラバーマウント部材１０２を介してマウントされたエンジン等の供試体１０３の回転軸に、例えば雄のスプライン軸１０４を取り付ける一方、ダイナモメータ（図示省略）の回転軸（被連結軸）１０５にユニバーサルジョイント１０６等を介して前記スプライン軸１０４を嵌合する場合、例えば雌のスプライン軸１０７を取り付け、該スプライン軸１０７を軸支持体１０８で支持する。   When connecting the rotating shafts to each other, for example, when performing a spline connection between the rotating shaft of a specimen such as an engine and the rotating shaft of a dynamometer when performing an engine unit test, as shown in FIG. For example, a male spline shaft 104 is attached to a rotation shaft of a specimen 103 such as an engine mounted via a rubber mount member 102, while a universal joint 106 is connected to a rotation shaft (connected shaft) 105 of a dynamometer (not shown). When the spline shaft 104 is fitted through, for example, a female spline shaft 107 is attached, and the spline shaft 107 is supported by a shaft support 108.

そして、軸支持体１０８をエアーシリンダ等の軸支持体駆動機構１０９で供試体１０３側に移動させ、スプライン軸１０４とスプライン軸１０７を嵌合させて、供試体の回転軸とダイナモメータの回転軸を連結する。スプライン軸１０７とスプライン軸１０４に芯ずれを起こしている場合には、前記ユニバーサルジョイント１０６等で芯ずれを吸収する。（例えば特許文献１〜３参照）   Then, the shaft support 108 is moved to the specimen 103 side by a shaft support driving mechanism 109 such as an air cylinder, the spline shaft 104 and the spline shaft 107 are fitted, and the rotating shaft of the specimen and the rotating shaft of the dynamometer Are connected. When misalignment occurs between the spline shaft 107 and the spline shaft 104, the misalignment is absorbed by the universal joint 106 or the like. (For example, see Patent Documents 1 to 3)

ところで、スプライン連結構造には、次に述べるような問題点がある。
（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が反面、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７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。 Incidentally, the spline connection structure has the following problems.
(1) When the spline shaft 104 and the spline shaft 107 are fitted, shaft runout or the like occurs due to a gap (play) existing between the spline groove of the spline shaft 104 and the spline groove of the spline shaft 107. This gap is indispensable for smoothly fitting the spline shaft 104 and the spline shaft 107. The larger the gap is, the easier the fitting between the spline shaft 104 and the spline shaft 107 is. On the other hand, shaft runout (backlash) also increases. In particular, when a rotating body such as a motor or an engine connected to a spline is fixed via an elastic body such as a rubber mount member, the axial position of the specimen becomes unstable or changes, There has been a problem of occurrence of vibration and resonance due to the fitting error of the female spline shafts 104 and 107. This is because in spline connection, only the force in the direction of the rotation axis is transmitted, and fixing in the direction perpendicular to the axis cannot be sufficiently fixed because there is a fitting error in spline connection. In particular, when the shaft support 108 that supports the dynamometer-side spline shaft 107 is, for example, a floating bearing shown in Patent Document 3, shaft shake and resonance are likely to occur.
(2) Contrary to the above (1), the smaller the gap is, the more the shaft shake can be suppressed, but the fitting between the spline shaft 104 and the spline shaft 107 becomes difficult. As a method for suppressing shaft runout without reducing the gap, a method of increasing the fitting length of the spline shaft, reducing the gap, and fixing the shaft in a direction perpendicular to the shaft can be considered. Further, since the length of the coupling shaft is increased and the stroke amount of the shaft support driving mechanism 109 in FIG. 7 is required, there is a problem that the entire apparatus is increased in size.

本発明は、前記従来の問題点を解決し、スプライン軸の嵌合を困難にする間隙を少なくすることなく、また、スプライン連結構造を使用する装置の長大化を招く原因であるスプライン軸を長くすることなく、軸ぶれ等を確実に抑制することの可能なスプライン連結構造を提供することにある。   The present invention solves the above-described conventional problems, does not reduce the gap that makes it difficult to fit the spline shaft, and lengthens the spline shaft, which is a cause of increasing the length of the device using the spline connection structure. It is an object of the present invention to provide a spline connecting structure that can reliably suppress shaft runout and the like without doing so.
