Description
【０００１】[0001]
本考案は一般に各種の機械、設備、装置等にあって、溝部或いはフランジ壁部 等の接続部に介装して挾圧される金属製ガスケットの構造の改良に関するもので ある。 The present invention generally relates to an improvement in the structure of a metal gasket, which is present in various machines, equipment, devices, and the like, and which is interposed and clamped in a connecting portion such as a groove portion or a flange wall portion.
【０００２】[0002]
従来、この種のガスケットとしては例えば図３に示すように、細径からなる金 属弾性管材の単体による断面欠円状の環体構造によって本体(11)を構成していた 。 Conventionally, as a gasket of this type, as shown in FIG. 3, for example, the main body (11) is constituted by a ring-shaped structure having a circular cross section made of a single metal elastic tube member having a small diameter.
【０００３】[0003]
しかしながら、このような従来の技術においては、前記単体による構造のため 、溝部或いはフランジ壁部での表面との充分なシール性と弾発性とを同時に発揮 せしめることに欠ける傾向にあり、長期に亘る圧縮状態でのクリープと耐疲労強 度の劣化とに相乗して、概して短期にシール機能の低下を余儀なくされる問題を 有するものであった。 However, such a conventional technique tends to lack sufficient ability to simultaneously exhibit sufficient sealing property with the surface of the groove portion or the flange wall portion and elasticity due to the structure made of the above-mentioned single body, and thus it is difficult to achieve long-term There was a problem in which the sealing function deteriorated generally in a short period of time, synergistically with creep under compression over time and deterioration of fatigue strength.
【０００４】 本考案は従来技術の有する前記問題に鑑みてなされたものであり、相手表面で の充分なシール性と弾発性とを同時に、しかも効果的に発揮すると共に、クリー プすることなく長期に亘る耐疲労強度の劣化の憂いを軽減してシール機能を確実 に保持することのできる金属製ガスケットを提案することを目的とするものであ る。The present invention has been made in view of the above-mentioned problems of the prior art, and exhibits sufficient sealability and elasticity on the mating surface simultaneously, effectively, and without creeping. It is an object of the present invention to propose a metal gasket that can reliably maintain the sealing function by reducing the fear of deterioration of fatigue strength over a long period of time.
【０００５】[0005]
本考案は上記目的を達成するため、金属帯材を幅手方向に亘り軟質材側を最 外側に位置して渦巻き状に重合して形成した比較的軟質材と硬質材とによる本体 を、その両側端部の少くとも軟質材を相互に連結して環状となして構成した金属 製ガスケットを要旨とし、更に前記連結を溶接又はろう付により行った後研摩し て構成するものである。 In order to achieve the above object, the present invention provides a main body made of a relatively soft material and a hard material, which is formed by superposing a metal strip in the width direction in a spiral shape with the soft material side being the outermost side. The main point is a metal gasket which is formed by connecting at least soft materials at both ends with each other to form an annular shape. Further, the connection is made by welding or brazing and then polishing.
【０００６】[0006]
本考案はこのように構成されているため、前記最外側に位置する軟質材により 相手表面でのシール性を充分となし、同時に内側に硬質材を設けた多重の渦巻き 状の重合構造によって弾発性をも同時に、しかも効果的に発揮せしめることがで き、更にクリープすることなく長期に亘り圧縮状態での耐疲労強度を充分となし てシール機能を確実に保持することができることとなる。 Since the present invention is configured in this way, the soft material located on the outermost side provides sufficient sealing performance on the mating surface, and at the same time, the elastic material is reinforced by the multiple spiral polymer structure with the hard material provided inside. At the same time, it is possible to effectively exhibit the properties, and it is possible to reliably maintain the sealing function for a long period of time with sufficient fatigue resistance in a compressed state without creeping.

以下、本考案の実施例を図面に基づいて説明すれば、図１は本考案の金属製弾 性Ｏ−リングの平面図、図２は図１Ａ−Ａ線の拡大による切断端図であり、(1) は本体であり、金属帯材を幅手方向に亘り軟質材側を最外側に位置して渦巻き状 に重合して形成した比較的軟質材(2) と硬質材(3) とにより形成されたものであ り、その両側端部の少くとも軟質材(2) をバット溶着又はろう付等により連結(4 ) して環状に構成した後、研摩にて成形及びシール面としての表面粗さを出すよ うにしたものである。尚金属帯材での前記軟質材(2) としては、アルミニウム、 銅、インジウム、ロジウム、ステンレス或いはチタニウム等からなるものであり 、また硬質材(3) としては、ステンレス、バネ鋼、燐青銅、インコネル或いはチ タニウム合金等によるものである。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a metallic elastic O-ring of the present invention, and FIG. (1) is the main body, which consists of a relatively soft material (2) and a hard material (3) formed by superimposing a metal strip in a spiral shape with the soft material side being the outermost side in the width direction. It is formed, and at least the soft material (2) at both ends is connected (4) by butt welding or brazing to form an annular shape, and then is ground by polishing and the surface as a sealing surface. It is designed to have roughness. The soft material (2) in the metal strip is made of aluminum, copper, indium, rhodium, stainless steel, titanium, etc., and the hard material (3) is stainless steel, spring steel, phosphor bronze, It is made of Inconel or titanium alloy.

以上説明したように本考案による金属製ガスケットは、特に本体(1) を金属帯 材による前記軟質材(2) と硬質材(3) とによる該軟質材側を最外側に位置して渦 巻き状に重合して形成してなるため、相手表面での充分なシール性と弾発性とを 同時に、しかも効果的に発揮せしめることができると共に、長期に亘ってクリー プすることなく耐疲労強度を充分となしてシール機能を確実に保持することので きる等、極めて有用な金属製ガスケットである。 As described above, in the metal gasket according to the present invention, in particular, the main body (1) is swirled with the soft material (2) and the hard material (3) made of a metal strip being located on the outermost side of the soft material. Since it is formed by polymerizing in a uniform shape, it is possible to exert sufficient sealing property and elasticity on the mating surface at the same time and effectively, and it also has fatigue resistance without creeping for a long period of time. It is a very useful metal gasket that can sufficiently maintain the sealing function.
