Description

本発明は、二軸間に介装されて回転トルクを伝達するとともに二軸間における芯ズレ、角変位または軸方向変位などのミスアライメントを吸収するダイアフラムカップリングに関する。   The present invention relates to a diaphragm coupling that is interposed between two shafts to transmit rotational torque and absorb misalignment such as misalignment, angular displacement, or axial displacement between the two shafts.

従来から図８に示すように、互いに軸方向に対向する一対のフランジ５２間にダイアフラム５３を介してセンターチューブ５４を同軸的に連結してなるダイアフラムカップリング５１が知られている。一対のフランジ５２は、その一方５２Ａが駆動軸側に連結されるとともに他方５２Ｂが従動軸側に連結され、よって上記したように回転トルクを伝達するとともに金属薄板よりなるダイアフラム５３が変形することでミスアライメントを吸収する。   Conventionally, as shown in FIG. 8, there has been known a diaphragm coupling 51 in which a center tube 54 is coaxially connected via a diaphragm 53 between a pair of flanges 52 facing each other in the axial direction. One of the pair of flanges 52 is connected to the drive shaft side and the other 52B is connected to the driven shaft side, so that the rotational torque is transmitted and the diaphragm 53 made of a thin metal plate is deformed as described above. Absorbs misalignment.

図９に示すようにダイアフラム５３は、比較的厚肉の内周取付部５３ａおよび外周取付部５３ｂの間に比較的薄肉の膜部５３ｃを一体成形したものであって、膜部５３ｃはその厚み寸法がその内周側端部５３ｃａから外周側端部５３ｃｂへかけて漸次薄くなるように形成されている（内周側端部５３ｃａの厚みをｔ１、外周側端部５３ｃｂの厚みをｔ２として、ｔ１＞ｔ２）。 As shown in FIG. 9, the diaphragm 53 is formed by integrally forming a relatively thin film portion 53c between a relatively thick inner peripheral attachment portion 53a and an outer peripheral attachment portion 53b, and the film portion 53c has a thickness thereof. The dimension is formed so that the dimension gradually decreases from the inner peripheral end 53ca to the outer peripheral end 53cb (the thickness of the inner peripheral end 53ca is t 1 , and the thickness of the outer peripheral end 53cb is t 2. As t 1 > t 2 ).

しかしながら、上記従来技術では上記したようにダイアフラム５３の膜部５３ｃがその内周側端部５３ｃａから外周側端部５３ｃｂへかけて漸次薄くなるように形成されているのみで、膜部５３ｃの表面（厚み方向両面）は平坦面のままとされている。   However, in the prior art, as described above, the film portion 53c of the diaphragm 53 is only formed so as to gradually become thinner from the inner peripheral side end portion 53ca to the outer peripheral side end portion 53cb. (Both sides in the thickness direction) remain flat.

したがって、ダイアフラム５３に設定される仕様がもっぱら膜部５３ｃの厚み寸法によって定められることになり、これに対し、厚み寸法以外の要素によってダイアフラム５３の仕様を変更することができれば、設計の自由度を拡大することができる。   Therefore, the specification set for the diaphragm 53 is determined solely by the thickness dimension of the film portion 53c. On the other hand, if the specification of the diaphragm 53 can be changed by an element other than the thickness dimension, the degree of freedom in design is reduced. Can be enlarged.

本発明は以上の点に鑑みて、ダイアフラムの設計の自由度を拡大することができるダイアフラムカップリングを提供することを目的とする。   In view of the above, it is an object of the present invention to provide a diaphragm coupling capable of expanding the degree of freedom in designing a diaphragm.

上記目的を達成するため、本発明のダイアフラムカップリングは、互いに軸方向に対向する一対のフランジ間にダイアフラムを介してセンターチューブを同軸的に連結してなるダイアフラムカップリングにおいて、前記ダイアフラムの表面に、表面上一部の凸部または／および凹部よりなる立体形状を設けたことを特徴とする。   In order to achieve the above object, a diaphragm coupling according to the present invention is a diaphragm coupling in which a center tube is coaxially connected through a diaphragm between a pair of flanges facing each other in the axial direction, on the surface of the diaphragm. Further, a three-dimensional shape comprising a part of the convex portions or / and concave portions on the surface is provided.

ダイアフラムの表面に表面上一部の凸部または／および凹部よりなる立体形状を設けると、この凸部や凹部の形状、角度、位置、数などを変更することにより、用途に適したダイアフラムを設計することが可能とされる。   When a three-dimensional shape is formed on the surface of the diaphragm, consisting of some convexes and / or depressions on the surface, the shape, angle, position, number, etc. of the projections and depressions can be changed to design a diaphragm suitable for the application. It is possible to do.

ｉ．ダイアフラム厚み方向一方の面に凸部および凹部を双方設け、他方の面に凹部を設ける。
ｊ．上記ｄ〜ｉにおいて、ダイアフラム厚み方向一方の面と同じ配置・形状などで他方の面に凸部または／および凹部を設ける。
ｋ．上記ｄ〜ｉにおいて、ダイアフラム厚み方向一方の面と異なる配置・形状などで他方の面に凸部または／および凹部を設ける。
ｌ．ダイアフラムを複数枚が並列した状態で装着されるものとし、各ダイアフラムの表面に表面上一部の凸部または／および凹部よりなる立体形状を設ける。 In providing a part of the three-dimensional shape on the surface of the diaphragm, various modes are conceivable as follows.

ダイアフラムの表面に表面上一部の立体形状を設ける手法としては、３Ｄプリンターのような積層式によるもの、鋳造のような型によるもの、鍛造やプレスのような加工によるもの等、様々な手法が考えられる。   There are various methods for providing a three-dimensional shape on the surface of the diaphragm, such as a layered type such as a 3D printer, a die like a casting, or a process like forging or pressing. Conceivable.

また、これらの手法によってダイアフラムの表面に表面上一部の立体形状を設けるに際しては、ダイアフラム膜部をその内周側端部から外周側端部へかけて漸次薄くなるように形成するのではなく、膜部を均一の厚さに設定し、そのうえでこの均一の厚さとした膜部の表面に立体形状を設けるようにしても良く、このようにすれば、ダイアフラム膜部を漸次薄肉に形成するための特殊加工機を用いる必要がないため、ダイアフラムの製造を容易化することが可能とされる。   In addition, when providing a three-dimensional shape on the surface of the diaphragm by these methods, the diaphragm film portion is not formed so as to gradually become thinner from the inner peripheral end to the outer peripheral end. The film portion may be set to a uniform thickness, and then a three-dimensional shape may be provided on the surface of the film portion having the uniform thickness. In this way, the diaphragm film portion is formed gradually thin. Since it is not necessary to use a special processing machine, it is possible to facilitate the manufacture of the diaphragm.

本発明によれば、ダイアフラムの表面に表面上一部の凸部または／および凹部よりなる立体形状を設けることによりダイアフラムの設計の自由度を拡大することができ、膜部を均一の厚さとしたうえで立体形状を設けることにより、ダイアフラムの製造を容易化することができる。   According to the present invention, it is possible to expand the degree of freedom in designing the diaphragm by providing a three-dimensional shape consisting of a convex part or / and a concave part on the surface of the diaphragm, and the film part has a uniform thickness. Further, by providing a three-dimensional shape, the manufacture of the diaphragm can be facilitated.

つぎに本発明の実施例を図面にしたがって説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の実施例に係るダイアフラムカップリング１１の一部切欠した正面を示している。このダイアフラムカップリング１１は、互いに軸方向に対向する一対のフランジ１３間にダイアフラム１４を介してセンターチューブ１５を同軸的に連結した基本構成を備え、更に、ダイアフラム１４が以下のように構成されている。尚、フランジ１３は、軸（図示せず）に装着されるハブ１２にその一部として設けられている。   FIG. 1 shows a partially cutaway front view of a diaphragm coupling 11 according to an embodiment of the present invention. The diaphragm coupling 11 includes a basic configuration in which a center tube 15 is coaxially connected via a diaphragm 14 between a pair of flanges 13 that are axially opposed to each other. Further, the diaphragm 14 is configured as follows. Yes. The flange 13 is provided as a part of the hub 12 mounted on a shaft (not shown).

すなわち図２、図３および図６（Ａ）に拡大して示すように、ダイアフラム１４はその表面に、表面上一部の凸部または／および凹部よりなる立体形状２１が当該ダイアフラム１４の中心軸線０を中心とする点対称構造で設けられている。   That is, as shown in an enlarged view in FIGS. 2, 3, and 6 (A), the diaphragm 14 has a three-dimensional shape 21 formed of a convex portion or / and a concave portion on the surface on the surface, and the central axis of the diaphragm 14. It is provided with a point-symmetrical structure centered on zero.

また、ダイアフラム１４は、所定の金属材料をもって平板環状に成形され、比較的厚肉の内周取付部１４ａおよび外周取付部１４ｂの間に比較的薄肉の膜部１４ｃを一体成形したものであって、膜部１４ｃはその厚み寸法がその内周側端部１４ｃａから外周側端部１４ｃｂへかけて漸次薄くなるように形成され（内周側端部１４ｃａの厚みをｔ１、外周側端部１４ｃｂの厚みをｔ２として、ｔ１＞ｔ２）、この膜部１４ｃの厚み方向一方の面に上記立体形状２１が設けられている。 The diaphragm 14 is formed into a flat plate shape with a predetermined metal material, and a relatively thin film portion 14c is integrally formed between a relatively thick inner peripheral mounting portion 14a and an outer peripheral mounting portion 14b. The film portion 14c is formed so that its thickness dimension gradually decreases from the inner peripheral side end portion 14ca to the outer peripheral side end portion 14cb (the thickness of the inner peripheral side end portion 14ca is t 1 , and the outer peripheral side end portion 14cb the thickness as t 2, t 1> t 2 ), the three-dimensional shape 21 is provided on one surface thickness direction of the film portion 14c.

立体形状２１としては具体的には、複数（多数）の凸部２２が円周上一定間隔で等配状に設けられており、凸部２２はそれぞれ長さ方向を備える直線的な凸条とされ、長さ方向一方の端部２２ａおよび他方の端部２２ｂは円周方向に変位していて、これにより凸部２２はネジ状（スパイラル状）とされている。ネジ状の凸部２２は、回転時に空気流（動圧）を発生させることにより、自己冷却機能を発揮することができるものである。   Specifically, as the three-dimensional shape 21, a plurality of (many) convex portions 22 are provided in a uniform manner at regular intervals on the circumference, and the convex portions 22 are linear ridges each having a length direction. In addition, one end 22a and the other end 22b in the length direction are displaced in the circumferential direction, whereby the protrusion 22 has a screw shape (spiral shape). The screw-like convex portion 22 can exhibit a self-cooling function by generating an air flow (dynamic pressure) during rotation.

ネジ状の凸部２２は、直線状でなく、曲線状であっても良い。図４および図５に示す例では、複数（多数）の凸部２２が円周上一定間隔で等配状に設けられており、凸部２２はそれぞれ長さ方向を備える曲線的な凸条とされ、長さ方向一方の端部２２ａおよび他方の端部２２ｂは円周方向に変位していて、これにより凸部２２はネジ状（スパイラル状）とされている。流体の流れを含めて考慮すると直線よりも曲線のほうが、効率が高く、範囲を広く採ることができる。   The screw-like convex portion 22 may be curved instead of linear. In the example shown in FIGS. 4 and 5, a plurality (large number) of convex portions 22 are provided in a uniform manner at regular intervals on the circumference, and the convex portions 22 each have a curved ridge having a length direction. In addition, one end 22a and the other end 22b in the length direction are displaced in the circumferential direction, whereby the protrusion 22 has a screw shape (spiral shape). In consideration of the fluid flow, the curve is more efficient than the straight line, and a wide range can be taken.

上記構成によれば、凸部２２の形状、角度、位置、数などを変更することによって、用途に適したダイアフラム１４を設計することが可能とされる。したがってダイアフラム１４についての設計の自由度を拡大することができる。また、複数の凸部２２よりなる立体形状２１が当該ダイアフラム１４の中心軸線０を中心とする点対称構造で設けられているため、立体形状２１を設けてもダイアフラム１４の回転バランスが偏ることがない。   According to the above configuration, the diaphragm 14 suitable for the application can be designed by changing the shape, angle, position, number, and the like of the protrusions 22. Accordingly, the degree of freedom in designing the diaphragm 14 can be expanded. In addition, since the solid shape 21 including the plurality of convex portions 22 is provided in a point-symmetric structure with the central axis 0 of the diaphragm 14 as the center, even if the solid shape 21 is provided, the rotational balance of the diaphragm 14 may be biased. Absent.
