本考案は、エンジンから排出される排気ガスの浄化用触媒担持体に係り、特に 波状プレートと平板プレートとを重ね合わせ渦巻状にしてコアを構成し、そのコ アの両端面にサイド部材を配置してケーシングに収納したものに関する。 The present invention relates to a catalyst carrier for purifying exhaust gas emitted from an engine, and in particular, a corrugated plate and a flat plate are superposed on each other to form a spiral core, and side members are arranged on both end surfaces of the core. And then stored in a casing.

この種の排気ガス浄化用触媒担持体は、波形金属プレートと平坦な金属プレー トとを渦巻状に形成すると共に、波形金属プレートと平坦な金属プレートとの接 触部をろう付けしてコアを形成し、該コアの外周とケーシングとの間を接合した ものが提案されていた。 又、波形金属プレートと平坦な金属プレートとの間をろう付けしないものにお いては、コアをケーシングに挿入すると共に、その両端面にサイド部材を配置し 且つ、両サイド部材間の中心を軸で連結固定したものが提案されていた。 This type of catalyst carrier for exhaust gas purification forms a corrugated metal plate and a flat metal plate in a spiral shape, and brazes the contact portion between the corrugated metal plate and the flat metal plate to form the core. It has been proposed that the core is formed and the outer periphery of the core is joined to the casing. Also, in the case where the corrugated metal plate and the flat metal plate are not brazed, the core is inserted into the casing, the side members are arranged on both end faces of the core, and the center between both side members is set to the axis. It was proposed to be connected and fixed in.

ところがこれらの浄化用触媒担持体は何れも、使用中、熱膨張により接合部に 亀裂が生じ易い欠点があった。これは、高温の排気ガスのためコアの中心部程高 温になり、ケーシングの熱膨張とコアのそれとの間に差が生じるためである。 そこで本考案は係る問題点を解決するため、次の構成をとる。 However, each of these purification catalyst carriers has a drawback that cracks easily occur at the joint due to thermal expansion during use. This is because the temperature of the central part of the core becomes higher due to the hot exhaust gas, which causes a difference between the thermal expansion of the casing and that of the core. Therefore, the present invention adopts the following configuration in order to solve such a problem.
【０００４】[0004]
本考案の排気ガス浄化用触媒担持体は、波状プレート２と平板プレート３とが 重ね合わされて渦巻状に巻回されたコア４を有し、そのコア４の中心に小径の貫 通孔１が形成される。そしてコア４の外周に等しく中心からリブ５が形成された 一対のサイド部材６を有し、それがコア４の軸方向両端面に配置される。 さらに、貫通孔１に軸部材７が挿通され一対のサイド部材６間を連結する。そ して、コア４がケーシング８に内装される。このケーシング８の内周面とコア４ の外周面との間には隙間Δｈ1 が形成されている。The exhaust gas purifying catalyst carrier of the present invention has a core 4 in which a corrugated plate 2 and a flat plate 3 are superposed and spirally wound, and a small-diameter through hole 1 is formed at the center of the core 4. It is formed. The core 4 has a pair of side members 6 equally formed on the outer periphery of the core 4 from the center, and the side members 6 are arranged on both axial end faces of the core 4. Further, the shaft member 7 is inserted into the through hole 1 to connect the pair of side members 6 to each other. Then, the core 4 is installed in the casing 8. A gap Δh 1 is formed between the inner peripheral surface of the casing 8 and the outer peripheral surface of the core 4.
【０００５】[0005]
本考案の浄化用触媒担持体は、ケーシング８の内周面とコア４の外周面との間 に隙間Δｈ1 が形成されているから、高温の排気ガスにさらされたとき、コア４ の熱膨張とケーシング８の熱膨張との間に差が生じても、それを隙間Δｈ1 が吸 収し、浄化用触媒担持体に亀裂を生じることがない。 しかも、コアは両サイド部材６と軸部材７とで保持されて、排気ガスの流通や 各種振動等により移動する虞がない。In the purifying catalyst carrier of the present invention, the gap Δh 1 is formed between the inner peripheral surface of the casing 8 and the outer peripheral surface of the core 4, so that the heat of the core 4 can be reduced when exposed to high temperature exhaust gas. Even if there is a difference between the expansion and the thermal expansion of the casing 8, the gap Δh 1 absorbs the difference, and the purification catalyst carrier is not cracked. Moreover, the core is held by the side members 6 and the shaft member 7, and there is no possibility that the core will move due to circulation of exhaust gas or various vibrations.

次に図面に基づいて本考案の実施例につき説明する。 図１は本考案の排気ガス浄化用触媒担持体の分解斜視図であり、図２はそのリ ブ５の横断面図である。又、図３はその完成状態を示す斜視図、図４は同縦断面 図、図５は渦巻状コア４を製造する方法を示す説明図である。 この触媒担持体は、図１に示す如くコア４と一対のサイド部材６と軸部材７と ケーシング８とを有する。コア４は、図５に示す如く中心に配置したインナーチ ューブ９の回りに平板プレート３と波状プレート２とを重ね合わせて渦巻状に形 成し、最外周に平板プレートを巻付けてその先端縁が接合されて、そこに図１の 如く溶接部11が形成されたものである。 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of an exhaust gas purifying catalyst carrier of the present invention, and FIG. 2 is a cross-sectional view of a rib 5 thereof. 3 is a perspective view showing the completed state, FIG. 4 is a longitudinal sectional view of the same, and FIG. 5 is an explanatory view showing a method of manufacturing the spiral core 4. As shown in FIG. 1, this catalyst carrier has a core 4, a pair of side members 6, a shaft member 7 and a casing 8. The core 4 is formed in a spiral shape by stacking the flat plate 3 and the wavy plate 2 around the inner tube 9 arranged at the center as shown in FIG. Are joined together, and the welded portion 11 is formed therein as shown in FIG.
【０００７】 次に、軸部材７の直径は貫通孔１の内直径よりも小さいものを用い、その一端 が一方のサイド部材６の中心に予め接合されている。各サイド部材６は、最外周 に環状部を有し、中心から放射方向にリブ５が複数環状部に向けて突設されてい る。なお、リブ５は図２に示す如くその横断面が中実の山形に形成され、或いは 図２ａの如く金属板を曲折した山形に形成されている。 なお、夫々のサイド部材６の外直径はコア４の外直径よりも僅かに大に形成さ れている。又、他方のサイド部材６の中心には、嵌着孔10が形成されている。こ の嵌着孔10の内直径は、軸部材７の外直径に整合する。Next, the diameter of the shaft member 7 is smaller than the inner diameter of the through hole 1, and one end thereof is preliminarily joined to the center of one side member 6. Each side member 6 has an annular portion on the outermost periphery, and ribs 5 are provided so as to project radially from the center toward the plurality of annular portions. The rib 5 is formed in a mountain shape whose cross section is solid as shown in FIG. 2, or in a mountain shape in which a metal plate is bent as shown in FIG. 2a. The outer diameter of each side member 6 is slightly larger than the outer diameter of the core 4. A fitting hole 10 is formed at the center of the other side member 6. The inner diameter of the fitting hole 10 matches the outer diameter of the shaft member 7.
【０００８】 次に、ケーシング８は筒状に形成され、その内直径がサイド部材６の外直径に 整合すると共に、コア４の外直径よりも僅かに大きく形成されている。そしてコ ア４のインナーチューブ９に軸部材７を貫通して一方のサイド部材６をコア４の 一側端に対向させると共に、軸部材７先端を他方のサイド部材６の嵌着孔10に挿 通させる。そして、これらをケーシング８内に挿入し、図３及び図４の如く組み 立てる。そして、サイド部材６の外周縁とケーシング８の側端とを溶接して、溶 接部11を形成させる。それと共に、軸部材７の先端とサイド部材６とを溶接する 。このとき、コア４の軸方向一端面とサイド部材６との間には隙間Δｂが形成さ れる。それと共に、コア４外周面とケーシング８内周面との間に隙間Δｈ1 が形 成される。さらに、インナーチューブ９の内周面と軸部材７外周面との間に隙間 Δｈ2 が形成される。Next, the casing 8 is formed in a tubular shape, and the inner diameter thereof is matched with the outer diameter of the side member 6 and is formed slightly larger than the outer diameter of the core 4. Then, the shaft member 7 is passed through the inner tube 9 of the core 4 so that one side member 6 faces one end of the core 4 and the tip of the shaft member 7 is inserted into the fitting hole 10 of the other side member 6. Pass through. Then, these are inserted into the casing 8 and assembled as shown in FIGS. Then, the outer peripheral edge of the side member 6 and the side end of the casing 8 are welded to form the welded portion 11. At the same time, the tip of the shaft member 7 and the side member 6 are welded. At this time, a gap Δb is formed between the axially one end surface of the core 4 and the side member 6. At the same time, a gap Δh 1 is formed between the outer peripheral surface of the core 4 and the inner peripheral surface of the casing 8. Further, a gap Δh 2 is formed between the inner peripheral surface of the inner tube 9 and the outer peripheral surface of the shaft member 7.
【０００９】 これらの隙間は、本担持体に高温の排気ガスを流通させたとき、各構成部品間 に熱膨張の差が生じてもそれを充分吸収できる大きさのものである。この担持体 の波状プレート２及び平板プレート３には、排気ガス浄化用の触媒が被覆され、 車両等のエンジンの排気路中に本担持体が取付けらる。そして、排気ガスはこの 担持体の軸方向に流通し、そのコア４通過中に触媒によって浄化されるものであ る。排気ガスがコア４を通過するとき、その中心部程熱膨張が大きくなりより長 く伸長する。このとき、コア４とサイド部材６との間には隙間Δｂが存在するた め、ケーシング８の熱膨張とコア４のそれとの間に差が生じても、その差を充分 吸収することができる。又、コア４の半径方向への熱膨張に対しては、Δｈ1 （ 図４）によってそれが吸収される。なお、排気ガス12は図２に示す如く、リブ５ の山の頂部側から流入しリブ５が大きな流体抵抗となることを防いでいる。 又、リブ５は図２ａの如く金属板を曲折して形成してもよく、その場合には触 媒担持体の軽量化に寄与できる。These gaps are of a size that can sufficiently absorb a difference in thermal expansion between the components when high-temperature exhaust gas is passed through the carrier. The corrugated plate 2 and the flat plate 3 of the carrier are coated with a catalyst for purifying exhaust gas, and the carrier is mounted in the exhaust passage of an engine such as a vehicle. The exhaust gas flows in the axial direction of the carrier and is purified by the catalyst while passing through the core 4. When the exhaust gas passes through the core 4, the central part of the exhaust gas has a larger thermal expansion and extends longer. At this time, since the gap Δb exists between the core 4 and the side member 6, even if there is a difference between the thermal expansion of the casing 8 and that of the core 4, the difference can be sufficiently absorbed. . Further, the thermal expansion of the core 4 in the radial direction is absorbed by Δh 1 (FIG. 4). As shown in FIG. 2, the exhaust gas 12 prevents the rib 5 from having a large fluid resistance by flowing in from the top of the peak of the rib 5. The rib 5 may be formed by bending a metal plate as shown in FIG. 2a, and in that case, it can contribute to weight reduction of the catalyst carrier.

本考案の浄化用触媒担持体は、ケーシングの内周面とコアの外周面との間に隙 間が形成されているから、使用中における両者の温度差等に基づく両者間の熱膨 張の差を吸収し、接合部の亀裂を防止して耐久性の高い担持体を提供できる。 しかも、コアをケーシング内にしっかりと支持できる。 In the catalyst carrier for purification of the present invention, a gap is formed between the inner peripheral surface of the casing and the outer peripheral surface of the core, so that the thermal expansion between the two due to the temperature difference between the two during use. It is possible to absorb the difference and prevent cracks at the joint portion to provide a highly durable carrier. Moreover, the core can be firmly supported in the casing.

次に図面に基づいて本考案の実施例につき説明する。 図１は本考案の排気ガス浄化用触媒担持体の分解斜視図であり、図２（ａ）は そのリブ５の横断面図である。又、図３はその完成状態を示す斜視図、図４は同 縦断面図、図５は渦巻状コア４を製造する方法を示す説明図である。 この触媒担持体は、図１に示す如くコア４と一対のサイド部材６と軸部材７と ケーシング８とを有する。コア４は、図５に示す如く中心に配置したインナーチ ューブ９の回りに平板プレート３と波状プレート２とを重ね合わせて渦巻状に形 成し、最外周に平板プレートを巻付けてその先端縁が接合されて、そこに図１の 如く溶接部１１が形成されたものである。 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of an exhaust gas purifying catalyst carrier of the present invention, and FIG. 2 (a) is a cross-sectional view of a rib 5 thereof. 3 is a perspective view showing the completed state, FIG. 4 is a longitudinal sectional view of the same, and FIG. 5 is an explanatory view showing a method of manufacturing the spiral core 4. As shown in FIG. 1, this catalyst carrier has a core 4, a pair of side members 6, a shaft member 7, and a casing 8. The core 4 is formed in a spiral shape by stacking the flat plate 3 and the wavy plate 2 around the inner tube 9 arranged at the center as shown in FIG. Are joined together, and the welded portion 11 is formed therein as shown in FIG.
【０００７】 次に、軸部材７の直径は貫通孔１の内直径よりも小さいものを用い、その一端 が一方のサイド部材６の中心に予め接合されている。各サイド部材６は、最外周 に環状部を有し、中心から放射方向にリブ５が複数環状部に向けて突設されてい る。なお、リブ５は図２（ａ）に示す如くその横断面が中実の山形に形成され、 或いは図２（ｂ）の如く金属板を曲折した山形に形成されている。 なお、夫々のサイド部材６の外直径はコア４の外直径よりも僅かに大に形成さ れている。又、他方のサイド部材６の中心には、嵌着孔１０が形成されている。 この嵌着孔１０の内直径は、軸部材７の外直径に整合する。Next, the diameter of the shaft member 7 is smaller than the inner diameter of the through hole 1, and one end thereof is preliminarily joined to the center of one side member 6. Each side member 6 has an annular portion at the outermost periphery, and ribs 5 are provided so as to project from the center toward the annular portion in a radial direction. The rib 5 is formed in a mountain shape whose cross section is solid as shown in FIG. 2 (a), or is formed in a mountain shape in which a metal plate is bent as shown in FIG. 2 (b). The outer diameter of each side member 6 is slightly larger than the outer diameter of the core 4. A fitting hole 10 is formed at the center of the other side member 6. The inner diameter of the fitting hole 10 matches the outer diameter of the shaft member 7.
【０００８】 次に、ケーシング８は筒状に形成され、その内直径がサイド部材６の外直径に 整合すると共に、コア４の外直径よりも僅かに大きく形成されている。そしてコ ア４のインナーチューブ９に軸部材７を貫通して一方のサイド部材６をコア４の 一側端に対向させると共に、軸部材７先端を他方のサイド部材６の嵌着孔１０に 挿通させる。そして、これらをケーシング８内に挿入し、図３及び図４の如く組 み立てる。そして、サイド部材６の外周縁とケーシング８の側端とを溶接して、 溶接部１１を形成させる。それと共に、軸部材７の先端とサイド部材６とを溶接 する。このとき、コア４の軸方向一端面とサイド部材６との間には隙間Δｂが形 成される。それと共に、コア４外周面とケーシング８内周面との間に隙間Δｈ１ が形成される。さらに、インナーチューブ９の内周面と軸部材７外周面との間に 隙間Δｈ２が形成される。Next, the casing 8 is formed in a tubular shape, and the inner diameter thereof is matched with the outer diameter of the side member 6 and is formed slightly larger than the outer diameter of the core 4. Then, the shaft member 7 is passed through the inner tube 9 of the core 4 so that one side member 6 faces one side end of the core 4, and the tip of the shaft member 7 is inserted into the fitting hole 10 of the other side member 6. Let Then, these are inserted into the casing 8 and assembled as shown in FIGS. Then, the outer peripheral edge of the side member 6 and the side end of the casing 8 are welded to form the welded portion 11. At the same time, the tip of the shaft member 7 and the side member 6 are welded. At this time, a gap Δb is formed between the axially one end surface of the core 4 and the side member 6.

Further, a gap Δh 2 is formed between the inner peripheral surface of the inner tube 9 and the outer peripheral surface of the shaft member 7.
【０００９】 これらの隙間は、本担持体に高温の排気ガスを流通させたとき、各構成部品間 に熱膨張の差が生じてもそれを充分吸収できる大きさのものである。この担持体 の波状プレート２及び平板プレート３には、排気ガス浄化用の触媒が被覆され、 車両等のエンジンの排気路中に本担持体が取付けらる。そして、排気ガスはこの 担持体の軸方向に流通し、そのコア４通過中に触媒によって浄化されるものであ る。排気ガスがコア４を通過するとき、その中心部程熱膨張が大きくなりより長 く伸長する。このとき、コア４とサイド部材６との間には隙間Δｂが存在するた め、ケーシング８の熱膨張とコア４のそれとの間に差が生じても、その差を充分 吸収することができる。又、コア４の半径方向への熱膨張に対しては、Δｈ１（ 図４）によってそれが吸収される。なお、排気ガス１２は図２（ａ）に示す如く 、リブ５の山の頂部側から流入しリブ５が大きな流体抵抗となることを防いでい る。 又、リブ５は図２（ｂ）の如く金属板を曲折して形成してもよく、その場合に は触媒担持体の軽量化に寄与できる。These gaps are of a size that can sufficiently absorb a difference in thermal expansion between the components when high-temperature exhaust gas is passed through the carrier.

Further, the thermal expansion of the core 4 in the radial direction is absorbed by Δh 1 (FIG. 4). As shown in FIG. 2A, the exhaust gas 12 prevents the rib 5 from having a large fluid resistance by flowing in from the top of the crest of the rib 5. The rib 5 may be formed by bending a metal plate as shown in FIG. 2B, and in that case, it can contribute to weight reduction of the catalyst carrier.
