Description
本発明は、駆動機構の技術分野に関し、より詳しくは、サーバーシステムに連結されるか、または両軸間を同期させる（一般的な伝動機構に適用される）カップリング（coupling）に関する。 The present invention relates to a technical field of a drive mechanism, and more particularly, to coupling that is coupled to a server system or that synchronizes both shafts (applied to a general transmission mechanism).
カップリングは機械伝動機構に応用される幅広い部材であり、カップリングは応用される部位または他の特殊な目的に合わせて、様々な型式の構造に設計される。蛇管カップリングは、慣性モーメントが低く、高温、高速回転に耐えられ、軸の偏位角度の補正、伸縮による緩衝、耐振性、及び伝動の同期等の機能を有し、ゆえに、一般的にサーボ駆動、デジタル制御伝動、或いは同期伝動等の超精密な機構中に応用されている。 Couplings are a wide range of components applied to mechanical transmission mechanisms, and couplings are designed in various types of structures to suit the application site or other special purpose. The serpentine coupling has a low moment of inertia, can withstand high temperature and high-speed rotation, and has functions such as correction of shaft deflection angle, buffering by expansion and contraction, vibration resistance, and synchronization of transmission. It is applied to ultra-precise mechanisms such as driving, digital control transmission, or synchronous transmission.
従来の蛇管カップリング構造は、図５及び図６に示すように、蛇管９１と、２つの外輪保持部９２と、２つの接合部９３とを主に備え、蛇管９１の両端が各外輪保持部９２及び接合部９３にそれぞれ連結されることにより、それらが相互に同軸（心）で対応しあう。各外輪保持部９２に対応しあう端面には嵌合溝９２２がそれぞれ設けられ、蛇管９１の両端の端縁部９１２が挿設される。 As shown in FIGS. 5 and 6, the conventional serpentine coupling structure mainly includes a serpentine tube 91, two outer ring holding portions 92, and two joint portions 93, and both ends of the serpentine tube 91 are each outer ring holding portion. By being respectively connected to 92 and the junction part 93, they correspond mutually coaxially (center). A fitting groove 922 is provided on each end face corresponding to each outer ring holding portion 92, and end edge portions 912 at both ends of the serpentine tube 91 are inserted.
また、図７及び図８は従来の蛇管カップリングの断面図であり、各外輪保持部９２の嵌合溝９２２が省略されて、蛇管９１の両端の端縁部９１２の長さが延長され、且つ各外輪保持部９２の外周面に積層される。バンドリング９４またはバンド９５がさらに組み合わせられて、蛇管９１及び各外輪保持部９２が固定される。 7 and 8 are cross-sectional views of a conventional snake tube coupling, the fitting grooves 922 of each outer ring holding portion 92 are omitted, and the lengths of the end edge portions 912 at both ends of the snake tube 91 are extended. In addition, the outer ring holding portions 92 are laminated on the outer peripheral surface. The band ring 94 or the band 95 is further combined to fix the serpentine tube 91 and each outer ring holding portion 92.
図８に示すバンド９５による結束方式では、応用の関係により、蛇管９１の両端の端縁部９１２により大きな座屈が容易に形成されることが分かった。 In the bundling method using the band 95 shown in FIG. 8, it has been found that large buckling is easily formed in the end edge portions 912 at both ends of the serpentine tube 91 due to the application relationship.
しかしながら、前述した従来の蛇管カップリング技術では、すなわち、上述の蛇管カップリング構造には、少なくとも以下の欠点が存在する。
１．剛性に優れない：蛇管９１は薄板で構成され、且つ両端は開放状態を呈するため、その端縁部９１２は剛性が不足するとう欠点がある。
２．真円度（circularity）に優れない：蛇管９１の両端の端縁部９１２は剛性が不足するため、蛇管９１の両端の端口を真円に維持できない。
３．嵌合及び装設が容易ではない：従来の蛇管９１の両端の端口は支持構造がない設計であるため、蛇管９１の端口を有効的に真円に維持できず、装設において、嵌合溝９２２に嵌挿させにくくなり、装設が困難で面倒になる。
４．座屈が発生しやすい。蛇管９１は薄板で構成されるため、蛇管９１の両端の端口に座屈現象が発生しやすい（図８参照）。
５．美観に優れない：蛇管９１は薄板で構成され、且つ両端は開放状態を呈する端縁部９１２であるため、鋭利な端面が形成されやすく、または座屈現象が発生しやすく、使用者が装設を行う上で危険である上に美観にも優れない等の欠点がある。
However, the above-described conventional serpentine tube coupling technique, that is, the aforementioned serpentine tube coupling structure has at least the following drawbacks.
1. Not excellent in rigidity: Since the snake tube 91 is formed of a thin plate and both ends are open, the end edge portion 912 has a drawback that the rigidity is insufficient.
2. Inferior circularity (circularity): Since the edge portions 912 at both ends of the snake tube 91 are insufficient in rigidity, the end ports at both ends of the snake tube 91 cannot be maintained in a perfect circle.
3. Fitting and installation are not easy: Since the end ports at both ends of the conventional serpentine tube 91 are designed without a support structure, the end ports of the serpentine tube 91 cannot be effectively maintained in a perfect circle. 922 is difficult to be inserted, making installation difficult and cumbersome.
4). Buckling is likely to occur. Since the snake tube 91 is formed of a thin plate, a buckling phenomenon is likely to occur at both ends of the snake tube 91 (see FIG. 8).
5. It is not excellent in aesthetics: The serpentine tube 91 is formed of a thin plate and both ends are end edges 912 that are open, so that a sharp end surface is easily formed or a buckling phenomenon is likely to occur. There are drawbacks such as being dangerous and not having good aesthetics.
そこで、本発明者は上記の欠点が改善可能と考え、鋭意検討を重ねた結果、合理的設計で上記の課題を効果的に改善する本発明の提案に至った。 Therefore, the present inventor considered that the above-described drawbacks can be improved, and as a result of intensive studies, the present inventors have arrived at a proposal of the present invention that effectively improves the above-described problems with rational design.

従って、上述は本発明の好ましい実施形態に係るカップリングの各部材及び装設方式の説明であり、次に、本発明の実施形態の作動の特徴を以下に説明する。 Therefore, the above is a description of each member and installation method of the coupling according to a preferred embodiment of the present invention. Next, features of operation of the embodiment of the present invention will be described below.
装設において、２つの外輪保持部２０の嵌合部２２は蛇管１０の両端の第一嵌挿部１２及び第二嵌挿部１４の内周縁にそれぞれ嵌合され、蛇管１０と外輪保持部２０との接触部位は粘着により固定される（従来の技術で常用される方式で嫌気性接着剤（anaerobic adhesive ）が使用される）。 In the installation, the fitting portions 22 of the two outer ring holding portions 20 are fitted to the inner peripheral edges of the first fitting insertion portion 12 and the second fitting insertion portion 14 at both ends of the bellows tube 10, respectively. The contact area is fixed by adhesion (an anaerobic adhesive is used in a conventional manner in the prior art).
使用において、先ず２つの接合部３０が２つの伝動軸４２及び伝動軸４４の接続端の外周縁にそれぞれ嵌合され、続いて、接合部３０が蛇管１０の両端の外輪保持部２０にそれぞれ嵌挿されて連結され、且つ複数のボルトにより接合部３０の孔部３３がそれぞれ穿通された後に外輪保持部２０のネジ穴２６に螺合され、これにより、接合部３０及び外輪保持部 ２０が固定される。ボルトによる螺合過程において、接合部３０及び外輪保持部２０が相互に接近され、軸方向の力の押し引きにより、外輪保持部２０の錐形状の嵌合孔２８により接合部３０の結合部３１が圧迫されて変形され、これにより、穿通される伝動軸４２及び伝動軸４４に対して挟まれることにより固結され、カップリングが２つの伝動軸４２４４の間に連結されて伝動される。 In use, first, the two joint portions 30 are fitted to the outer peripheral edges of the connection ends of the two transmission shafts 42 and 44, respectively, and then the joint portions 30 are fitted to the outer ring holding portions 20 at both ends of the serpentine tube 10, respectively.

Is done. In the screwing process using bolts, the joint portion 30 and the outer ring holding portion 20 are brought close to each other, and the coupling portion 31 of the joint portion 30 is caused by the conical fitting hole 28 of the outer ring holding portion 20 by pushing and pulling of the axial force. Is pressed and deformed, and is thereby fixed by being sandwiched between the transmission shaft 42 and the transmission shaft 44 to be penetrated, and the coupling is connected between the two transmission shafts 4244 and transmitted.
以上の構造的特徴及び装設と使用の説明後に、従来の蛇管カップリングと比較すると、本発明の設計は以下の特徴を有する
１．滑動による位置ずれが生じない：本発明の蛇管１０は複数枚の薄板が積層され、縁反り部１２２及び縁反り部１２４の構造設計により、蛇管が捻じれて運動エネルギーが伝達されて、積層される薄板が滑動して位置ずれが生じるということがなくなる。
２．端口が真円に保持される：蛇管１０の両端（すなわち、第一嵌挿部１２及び第二嵌挿部１４）の端口は縁反り部１２２及び縁反り部１２４の構造設計により、蛇管１０の両端口に好ましい支持構造が提供され、蛇管１０の両端の端口が真円に確保される。
３．嵌合及び装設が便利になる：蛇管１０の両端が真円を呈するため、装設において、端口の変形により嵌合が困難になることが無く、且つ端口の縁反り部１２２及び縁反り部１２４の構造設計により、嵌挿を案内する効果を有する。
４．端口が座屈しない：蛇管１０は薄板で構成され、端縁の縁反り部１２２及び縁反り部１２４の構造設計により、蛇管１０の両端の端口が座屈するという欠点が解消される。
５．美観が増す：蛇管９１は薄板で構成され、且つ両端の開放状態を呈する端縁部９１２には鋭利な端面が形成されやすく、使用者が装設する上で危険であったが、本発明の縁反り部１２２及び縁反り部１２４の構造設計により、美観を有するほか、鋭利な端面とうい欠点も解消される。
After the description of the above structural features and installation and use, the design of the present invention has the following features as compared with the conventional serpentine coupling: Misalignment due to sliding does not occur: The snake tube 10 of the present invention is formed by laminating a plurality of thin plates, and by structuring the edge warp portion 122 and the edge warp portion 124, the snake tube is twisted and kinetic energy is transmitted to be laminated. The thin plate does not slide and no displacement occurs.
2. The end mouth is held in a perfect circle: the end mouths of both ends of the snake tube 10 (that is, the first insertion insertion portion 12 and the second insertion insertion portion 14) are formed by the structural design of the edge warpage portion 122 and the edge warpage portion 124. A preferable support structure is provided at both end ports, and the end ports at both ends of the serpentine tube 10 are secured in a perfect circle.
3. Fitting and installation become convenient: since both ends of the flexible tube 10 have a perfect circle, the fitting does not become difficult due to the deformation of the end opening, and the edge warping portion 122 and the edge bending portion of the end opening are not difficult. The structural design of 124 has an effect of guiding insertion.
4). The end mouth does not buckle: The serpentine tube 10 is formed of a thin plate, and the structural design of the edge warp portion 122 and the edge warp portion 124 eliminates the drawback that the end ports at both ends of the serpentine tube 10 buckle.
5. Appearance increases: The serpentine tube 91 is formed of a thin plate, and a sharp end face is easily formed on the end edge portion 912 that is open at both ends, which is dangerous for the user to install. The structure design of the edge warp portion 122 and the edge warp portion 124 has an aesthetic appearance, and also eliminates sharp end faces and defects.
以上、本発明の実施形態について図面を参照して詳述したが、具体的な構成はこの実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等も含まれる。 As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
