Description
本考案は、軸管構造に係り、特に、充填気体を有する強化軸管構造に関する。 The present invention relates to a shaft tube structure, and more particularly to a reinforced shaft tube structure having a filling gas.
従来の軸管構造は、金属製の中実管からなる。金属材料の管材料は一定レベルの強度を有するが、重い金属材料からなるため、軸管構造が長いと管材料自体の重さにより曲がってしまう虞があった。そのため、軸管構造が重過ぎて曲がってしまう従来技術の問題点を改善することができる新たな管材料の充填技術が求められていた。 The conventional shaft tube structure consists of a solid metal tube. Although the metal tube material has a certain level of strength, it is made of a heavy metal material. Therefore, if the axial tube structure is long, the tube material may be bent due to the weight of the tube material itself. Therefore, there has been a demand for a new tube material filling technique that can improve the problems of the prior art in which the shaft tube structure is too heavy and bends.
従来の管材料充填技術では、管構造の強度を高めるために、曲がり難い金属材料（例えば、ステンレスまたはアルミニウム）が用いられていた。しかし、金属材料からなる管構造は一定レベルの強度を有するが、重量が非常に大きいため、一般に中空管にしたり軽量かつ高強度の材料（例えば、炭素繊維材料）を充填したりすることにより、管自体の重量を低減させていた。 In the conventional tube material filling technique, a metal material (for example, stainless steel or aluminum) which is difficult to bend is used in order to increase the strength of the tube structure. However, although the tube structure made of a metal material has a certain level of strength, it is very heavy, so it is generally made into a hollow tube or filled with a light weight and high strength material (for example, carbon fiber material). , Reducing the weight of the tube itself.
例えば、特許文献１では、車用管構造の技術が開示されている。特許文献１の車用管構造は、管体および発砲金属を含む。管体は、中空部を有し、折り曲げて特定の形状に形成することができる。発泡金属は、管体の中空部内に充填される。この発泡金属はポーラスな組織を有するため、管体内の発泡金属には複数のポーラスが形成されている。これにより、管体構造の強度および振動吸収能力を高めていた。 For example, Patent Document 1 discloses a technique for a vehicle pipe structure. The vehicle pipe structure of Patent Document 1 includes a pipe body and a foam metal. The tubular body has a hollow portion and can be bent to be formed into a specific shape. The foam metal is filled in the hollow portion of the tubular body. Since this foam metal has a porous structure, a plurality of porous materials are formed in the foam metal in the tube. As a result, the strength of the tubular structure and the vibration absorption capability were increased.
しかし、特許文献１の車用管構造は、管体に充填した発泡金属のため管体の構造強度および振動吸収性能が高かったが、管体の中に発泡金属が充填されていたため、管構造の重量が大きくなるだけでなく、製造コストも増大した。 However, the pipe structure for a vehicle of Patent Document 1 has a high structural strength and vibration absorption performance due to the foam metal filled in the pipe body. However, since the foam metal is filled in the pipe body, the pipe structure Not only increased the weight, but also increased the manufacturing cost.
本考案の第１の目的は、中空軸管空間の中に所定圧力の気体を充填し、強化軸管構造を軽量化させる充填気体を有する強化軸管構造を提供することにある。 A first object of the present invention is to provide a reinforced shaft tube structure having a filling gas that fills a hollow shaft tube space with a gas of a predetermined pressure and reduces the weight of the reinforced shaft tube structure.
本考案の第２の目的は、中空軸管空間の中に所定圧力の気体を充填し、強化軸管構造の機械強度を高める充填気体を有する強化軸管構造を提供することにある。 A second object of the present invention is to provide a reinforced shaft tube structure having a filling gas that fills a hollow shaft tube space with a gas of a predetermined pressure and increases the mechanical strength of the reinforced shaft tube structure.
本考案の第３の目的は、中空軸管空間の中に所定圧力の気体を充填し、製造コストを下げる充填気体を有する強化軸管構造を提供することにある。 A third object of the present invention is to provide a reinforced shaft tube structure having a filling gas that fills a hollow shaft tube space with a gas of a predetermined pressure and reduces the manufacturing cost.
上記課題を解決するために、本考案に係る充填気体を有する強化軸管構造は、軸管を備える。軸管は、所定長さＬの荷重部と、荷重部の２つの自由端に位置する第１の端部および第２の端部とを有する。第１の端部および前記第２の端部により封止構造が形成される。軸管の荷重部の内部には中空軸管空間が形成され、中空軸管空間の内壁には少なくとも１つの炭素繊維材料層が形成される。軸管の中空軸管空間の中には所定圧力の気体が充填され、軸管の中空軸管空間の内部と中空軸管空間の外部とに圧力差が生成され、軸管構造の強度を高める。 In order to solve the above problems, a reinforced shaft tube structure having a filling gas according to the present invention includes a shaft tube. The shaft tube has a load portion having a predetermined length L, and a first end and a second end located at two free ends of the load portion. A sealing structure is formed by the first end and the second end. A hollow shaft tube space is formed inside the load portion of the shaft tube, and at least one carbon fiber material layer is formed on the inner wall of the hollow shaft tube space. The hollow shaft tube space of the shaft tube is filled with a gas of a predetermined pressure, and a pressure difference is generated between the inside of the hollow shaft tube space of the shaft tube and the outside of the hollow shaft tube space, thereby increasing the strength of the shaft tube structure. .
本考案の充填気体を有する強化軸管構造は、軸管内部の中空軸管空間へ所定圧力の気体を充填し、軸管内部の中空軸管空間の圧力を軸管外部の圧力よりも高くして軸管の機械強度を高めている上、管状構造が強度不足により曲がったり変形したりすることを防ぐことができるため、高強度の軸管が必要な様々な設備へ広く応用することができる。また、軸管内部の気体を調整するだけで、軸管の曲げ度を適宜調整し、軸管の形状を変えることができる。また、軸管の内部に金属またはその他の材料を充填していた従来技術と異なり、本考案は軸管内部の中空軸管空間へ気体を充填することにより、軸管を軽量化させることができる上、製造工程でかかるコストを大幅に節減させることができる。 The reinforced shaft tube structure having a filling gas of the present invention fills the hollow shaft tube space inside the shaft tube with a predetermined pressure gas, and makes the pressure in the hollow shaft tube space inside the shaft tube higher than the pressure outside the shaft tube. In addition to increasing the mechanical strength of the shaft tube, the tubular structure can be prevented from being bent or deformed due to insufficient strength, so it can be widely applied to various facilities that require a high-strength shaft tube. . Moreover, the shape of a shaft tube can be changed by adjusting the bending degree of a shaft tube suitably only by adjusting the gas inside a shaft tube. Also, unlike the prior art in which the shaft tube is filled with metal or other materials, the present invention can reduce the weight of the shaft tube by filling the hollow shaft tube space inside the shaft tube with gas. In addition, the cost of the manufacturing process can be greatly reduced.
以下、図面を参照して本考案を詳細に説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.
図１は、本考案の第１実施形態による気体を充填する強化軸管構造を示す斜視図である。図２は、図１の線２−２に沿った断面図である。図１および図２に示すように、強化軸管構造１００は、軸管１を含む。軸管１は、所定長さＬである荷重部１０と、荷重部１０の２つの自由端１１，１２に位置する第１の端部２１および第２の端部２２と、を有する。第１の端部２１および第２の端部２２は、封止構造を形成する。軸管１の荷重部１０の中には、内壁に炭素繊維材料層１４が形成された中空軸管空間１３が設けられる。その後、中空軸管空間１３の中に所定圧力Ｐ１の気体３を充填することにより、軸管１の中空軸管空間１３の内部の所定圧力Ｐ１と、中空軸管空間１３の外部圧力Ｐ２とに圧力差が生成され、所定圧力Ｐ１の気体３を中空軸管空間１３へ充填し、軸管１の強度を高める。さらに、炭素繊維材料層１４が備える軽量かつ高強度の構造特性により、軸管１を軽量化し、構造強度を高めることができる。そのため、強化軸管構造１００は、高強度の軸管が必要な設備へ幅広く応用することができる。本実施形態では、中空軸管空間１３の内壁へ炭素繊維材料層１４を１層だけ形成して軸管１の構造強度を高めているが、この炭素繊維材料層１４は、必要に応じて複数層形成したり、或いは、炭素繊維材料をその他の材料（例えば、発泡多孔質プラスチック材料またはガラス繊維材料）に替えたりしてもよい。 FIG. 1 is a perspective view showing a reinforced shaft tube structure filled with gas according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. As shown in FIGS. 1 and 2, the reinforced shaft tube structure 100 includes a shaft tube 1. The shaft tube 1 has a load portion 10 having a predetermined length L, and a first end portion 21 and a second end portion 22 located at two free ends 11 and 12 of the load portion 10. The first end 21 and the second end 22 form a sealing structure. In the load portion 10 of the shaft tube 1, a hollow shaft tube space 13 having a carbon fiber material layer 14 formed on the inner wall is provided. After that, by filling the hollow shaft tube space 13 with the gas 3 having a predetermined pressure P1, a predetermined pressure P1 inside the hollow shaft tube space 13 of the shaft tube 1 and an external pressure P2 of the hollow shaft tube space 13 are obtained. A pressure difference is generated, and the hollow shaft tube space 13 is filled with the gas 3 having a predetermined pressure P1, and the strength of the shaft tube 1 is increased. Furthermore, the lightweight and high-strength structural characteristics of the carbon fiber material layer 14 can reduce the weight of the shaft tube 1 and increase the structural strength. Therefore, the reinforced shaft tube structure 100 can be widely applied to facilities that require a high-strength shaft tube. In the present embodiment, only one carbon fiber material layer 14 is formed on the inner wall of the hollow shaft tube space 13 to increase the structural strength of the shaft tube 1, but a plurality of carbon fiber material layers 14 may be provided as necessary. Alternatively, the carbon fiber material may be replaced with another material (for example, a foamed porous plastic material or a glass fiber material).
図３を参照する。図３は、本考案の一実施形態による気体を充填させる強化軸管構造にブラシを結合させたときの状態を示す断面図である。図３に示すように、従来の軸管構造では、軸管１へブラシ４が結合されると、ブラシ４自体が有する所定の重量Ｗを支えることができないため、曲がったり変形したりすることがあった。その場合、このブラシを使って清掃すると、ブラシの変形部分でしか清掃作業を行うことができず、効率良く清掃を行うことができなかった。これに対し、軸管１の中空軸管空間１３に充填した所定圧力Ｐ１の気体３と、中空軸管空間１３の内壁に形成した炭素繊維材料層１４とにより構造を強化し、ブラシ４の重量Ｗの負荷を軸管１により支え、曲がったり変形したりすることを防ぐことができる。本考案の第１実施形態では、強化軸管構造１００の軸管１にブラシ４が結合されているが、必要に応じて軸受、搬送ローラなどの設備へ応用することもできる。 Please refer to FIG. FIG. 3 is a cross-sectional view illustrating a state where a brush is coupled to a reinforced shaft tube structure filled with gas according to an embodiment of the present invention. As shown in FIG. 3, in the conventional shaft tube structure, when the brush 4 is coupled to the shaft tube 1, the brush 4 itself cannot support a predetermined weight W and may be bent or deformed. there were. In that case, when this brush was used for cleaning, the cleaning work could be performed only at the deformed portion of the brush, and the cleaning could not be performed efficiently. In contrast, the structure is reinforced by the gas 3 having a predetermined pressure P1 filled in the hollow shaft tube space 13 of the shaft tube 1 and the carbon fiber material layer 14 formed on the inner wall of the hollow shaft tube space 13, and the weight of the brush 4 is increased. The load of W is supported by the shaft tube 1 and can be prevented from being bent or deformed. In the first embodiment of the present invention, the brush 4 is coupled to the shaft tube 1 of the reinforced shaft tube structure 100. However, the brush 4 can be applied to facilities such as a bearing and a conveyance roller as necessary.
図４は、本考案の第２実施形態による強化軸管構造を示す斜視図である。図４に示すように、第２実施形態の強化軸管構造２００の構成および作用原理については、第１実施形態と略同じであるためここでは詳しく述べない。なお、同じ構成要素は同じ符号で表示されている。第２実施形態の軸管１ａは方形状の軸管であり、軸管１ａの中空軸管空間１３に充填した気体３と、炭素繊維材料層１４とにより構成された強化構造により、本実施形態の軸管１ａを支持ブラケット構造へ応用することができる。 FIG. 4 is a perspective view showing a reinforced shaft tube structure according to a second embodiment of the present invention. As shown in FIG. 4, the configuration and operating principle of the reinforced shaft tube structure 200 of the second embodiment are substantially the same as those of the first embodiment, and will not be described in detail here. In addition, the same component is displayed with the same code | symbol. The shaft tube 1a of the second embodiment is a rectangular shaft tube, and this embodiment has a reinforcing structure constituted by the gas 3 filled in the hollow shaft tube space 13 of the shaft tube 1a and the carbon fiber material layer 14. The shaft tube 1a can be applied to a support bracket structure.
図５は、本考案の第３実施形態による強化軸管構造を示す断面図である。図５に示すように、第３実施形態の強化軸管構造２００の構成および作用原理については、第２実施形態と略同じであるためここでは詳しく述べない。なお、同じ構成要素は同じ符号で表示されている。第３実施形態は、軸管１ａの内側に中空軸管空間１３の炭素繊維材料層が形成されている第２実施形態と異なり、軸管１ａの中空軸管空間１３に所定圧力Ｐ１の気体３を充填することにより、強化軸管構造２００の機械強度を高める。このように、第３実施形態では炭素繊維材料層が使用されていないため、軸管を軽量化させることができる上、製造コストを節減させることができる。 FIG. 5 is a cross-sectional view illustrating a reinforced shaft tube structure according to a third embodiment of the present invention. As shown in FIG. 5, the configuration and operating principle of the reinforced shaft tube structure 200 of the third embodiment are substantially the same as those of the second embodiment, and thus will not be described in detail here. In addition, the same component is displayed with the same code | symbol. Unlike the second embodiment in which the carbon fiber material layer of the hollow shaft tube space 13 is formed inside the shaft tube 1a, the third embodiment has a gas 3 having a predetermined pressure P1 in the hollow shaft tube space 13 of the shaft tube 1a. The mechanical strength of the reinforced shaft tube structure 200 is increased. Thus, since the carbon fiber material layer is not used in the third embodiment, the shaft tube can be reduced in weight and the manufacturing cost can be reduced.
図６は、本考案の第３実施形態による気体を充填させる強化軸管構造に気体通過構造を結合させたときの状態を示す断面図である。図６に示すように、軸管１ａの自由端１１の第１の端部２１に結合させた気体通過構造５ａを介し、第１の端部２１から軸管１ａの内部へ気体３を注入して中空軸管空間１３を形成する。さらに、軸管１ａの自由端１２に設けた第２の端部２２をもう一つの気体通過構造５ｂへ結合させることにより、軸管１ａの中空軸管空間１３に注入された気体３は、第２の端部２２を介して気体通過構造５ｂで回収することができる。軸管１ａの中空軸管空間１３に気体３を注入して得た所定圧力Ｐ１は、気体通過構造５ａおよび気体通過構造５ｂを利用することにより調整することができる。軸管１ａは、その内部にある気体を調整することにより、曲がり具合を適宜調整して形状を変えることができる。 FIG. 6 is a cross-sectional view illustrating a state where a gas passage structure is coupled to a reinforced shaft tube structure filled with gas according to a third embodiment of the present invention. As shown in FIG. 6, the gas 3 is injected from the first end portion 21 into the shaft tube 1a through the gas passage structure 5a coupled to the first end portion 21 of the free end 11 of the shaft tube 1a. Thus, the hollow shaft tube space 13 is formed. Further, by coupling the second end 22 provided at the free end 12 of the shaft tube 1a to another gas passage structure 5b, the gas 3 injected into the hollow shaft space 13 of the shaft tube 1a is It can be recovered by the gas passage structure 5 b through the two end portions 22. The predetermined pressure P1 obtained by injecting the gas 3 into the hollow shaft space 13 of the shaft tube 1a can be adjusted by using the gas passage structure 5a and the gas passage structure 5b. The shaft tube 1a can be changed in shape by adjusting the degree of bending as appropriate by adjusting the gas in the tube 1a.
図７は、本考案の第４実施形態による気体を充填する強化軸管構造を示す斜視図である。図８は、図７の線８−８に沿った断面図である。図７および図８に示すように、第４実施形態による強化軸管構造３００は軸管１ｂを含む。軸管１ｂは、プレート状の軸管である。軸管１ｂは、所定長さＬの荷重部１０と、荷重部１０に設けられた２つの自由端１１，１２の第１の端部２１および第２の端部２２と、を有する。第１の端部２１および第２の端部２２は、封止構造を形成する。軸管１ｂの荷重部１０の内部には、所定圧力Ｐ１の気体３が充填された中空軸管空間１３が形成されている。これにより、軸管１ｂの中空軸管空間１３の内部の所定圧力Ｐ１と、中空軸管空間の外部圧力Ｐ２とにより圧力差が生成される。さらに、軸管１ｂの中空軸管空間１３の内壁には炭素繊維材料層１４が形成されてもよい。炭素繊維材料は、軽量かつ高強度の特性を備えているため、炭素繊維材料層１４により軸管１ｂの強度を高めることができる。 FIG. 7 is a perspective view showing a reinforced shaft tube structure filled with gas according to a fourth embodiment of the present invention. FIG. 8 is a cross-sectional view taken along line 8-8 of FIG. As shown in FIGS. 7 and 8, the reinforced shaft tube structure 300 according to the fourth embodiment includes a shaft tube 1b. The shaft tube 1b is a plate-shaped shaft tube. The shaft tube 1 b includes a load portion 10 having a predetermined length L, and a first end portion 21 and a second end portion 22 of two free ends 11 and 12 provided on the load portion 10. The first end 21 and the second end 22 form a sealing structure. A hollow shaft tube space 13 filled with a gas 3 having a predetermined pressure P1 is formed inside the load portion 10 of the shaft tube 1b. Thereby, a pressure difference is generated by the predetermined pressure P1 inside the hollow shaft tube space 13 of the shaft tube 1b and the external pressure P2 of the hollow shaft tube space. Further, a carbon fiber material layer 14 may be formed on the inner wall of the hollow shaft tube space 13 of the shaft tube 1b. Since the carbon fiber material has characteristics of light weight and high strength, the carbon fiber material layer 14 can increase the strength of the shaft tube 1b.
