[産業上の利用分野]
本発明は、ロー材を用いた部材の接合構造に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a joining structure for members using brazing material.
[従来の技術]
従来、金属又はセラミツクからなる部材と金属
又はセラミツクからなる部材とを、一方の部材に
取付け穴を、他方の部材に挿入部を各々設け、上
記取付け穴と挿入部を嵌合させて接合することが
必要となる場合には、焼バメ、冷シバメ、圧入、
ロー材等によつて、接合を行なつていた。[Prior Art] Conventionally, a member made of metal or ceramic and a member made of metal or ceramic are provided with a mounting hole in one member and an insertion portion in the other member, and the mounting hole and the insertion portion are fitted. If it is necessary to join with
The joint was made using brazing material or the like.
しかし、焼バメ、冷シバメ、圧入の接合方法で
は、挿入部及び取付け穴の寸法が正確に加工され
ていないと十分な効果がでない。又、セラミツク
からなる部材同士の接合は、セラミツクの熱膨脹
率が低いためと靭性がそれほど高くないために焼
バメ、冷シバメ、圧入といつた方法を用いること
ができない。 However, the joining methods of shrink fit, cold fit, and press fit are not sufficiently effective unless the dimensions of the insertion portion and the mounting hole are precisely machined. Further, when joining members made of ceramic, methods such as shrink fitting, cold fitting, and press fitting cannot be used because ceramic has a low coefficient of thermal expansion and does not have very high toughness.
それに対し、挿入部外面と取付け穴内面との間
にロー材を充填するロー付による接合方法では、
挿入部及び取付け穴の寸法はそれほど正確である
必要はない。又、セラミツク同士であつても挿入
部外面及び取付け穴内面を金属で被膜した、いわ
ゆるメタライズ処理されているか、セラミツクに
対する濡れ性のよいロー材を用いるならば接合は
可能である。 On the other hand, in the joining method using brazing, which fills brazing material between the outer surface of the insertion part and the inner surface of the mounting hole,
The dimensions of the insert and mounting holes do not need to be very precise. Furthermore, it is possible to join ceramics together if the outer surface of the insertion part and the inner surface of the mounting hole are coated with metal, so-called metallization treatment, or if a brazing material with good wettability to ceramics is used.
ロー付による接合方法には、
挿入部を取付け穴に嵌合した後に取付け穴開
口部よりロー材を注入する方法。 The joining method by brazing involves fitting the insertion part into the mounting hole and then injecting brazing material through the opening of the mounting hole.
挿入部外面にロー材をつけてから取付け穴に
嵌合する方法。 A method in which brazing material is applied to the outer surface of the insertion part and then fitted into the mounting hole.
取付け穴内部にロー材を置き、その後加熱に
よつてロー材を軟化させ、次いで挿入部を押し
込む方法。 A method of placing brazing material inside the mounting hole, softening the brazing material by heating, and then pushing the insertion part.
等があるが、は挿入後の取付け穴開口部からロ
ー材を注入するために取付け穴及び挿入部の形状
が限られてしまう。又、均一な充填となりにく
い。は挿入部外面につくロー材の量を調整しに
くく、又、操作が複雑となる。によれば、比較
的簡単な操作で接合ができ、取付け穴を有する部
材の熱膨脹が比較的大きいと、冷却後に取付け穴
が収縮し、ロー材を介してて挿入部を締付けるこ
ととなり、より強固な接合を行なえる。However, since the brazing material is injected from the opening of the mounting hole after insertion, the shapes of the mounting hole and the insertion portion are limited. In addition, it is difficult to fill it uniformly. It is difficult to adjust the amount of brazing material applied to the outer surface of the insertion part, and the operation is complicated. According to , joining can be done with a relatively simple operation, and if the thermal expansion of the component with the mounting hole is relatively large, the mounting hole will contract after cooling, and the insertion part will be tightened through the brazing material, making it stronger. It is possible to perform various types of joints.
[発明が解決しようとする問題点]
しかし、ロー材と部材との濡れ性や押し込む際
に挿入部外面と取付け穴内面との間隙が、全周に
わたつて一定とすることがむつかしい等の理由に
より、挿入部外面と取付け穴内面との間隙部分全
てにロー材を均一に充填することは、決して容易
ではなかつた。[Problems to be solved by the invention] However, there are reasons such as the wettability of the brazing material and the component and the difficulty of keeping the gap between the outer surface of the insertion part and the inner surface of the mounting hole constant over the entire circumference when pushing. Therefore, it has never been easy to uniformly fill all the gaps between the outer surface of the insertion portion and the inner surface of the attachment hole with brazing material.
ロー材を流動化し易くしても、挿入部外面や取
付け穴内面を表面処理しても、やはりロー材を均
一に充填することはむつかしかつた。 Even if the brazing material is made easier to fluidize, and even if the outer surface of the insertion portion and the inner surface of the mounting hole are surface-treated, it is still difficult to uniformly fill the brazing material.
そのため、ロー材の不完全な部分あるいは全く
ロー付されていない部分が生じ、品質のよい製品
を安定して製造することができなかつた。 As a result, some parts of the brazing material were incomplete or not brazed at all, making it impossible to stably manufacture products of good quality.

によつて均一に充填されることになる。[Operation] When the insertion part is pushed into the mounting hole in which the heated, melted and softened brazing material is placed, the flowing brazing material moves up the gap between the inner surface of the mounting hole and the outer surface of the insertion part. Even if it begins to rise unevenly depending on the location, the inner surface of the mounting hole near the opening of the mounting hole and/or
Or, at a flow resistance part provided on the outer surface of the insertion part facing the inner surface of the mounting hole near the opening of the mounting hole,
The brazing material in the part that rose quickly is subjected to flow resistance,
The flow will turn to the side where the flow resistance is low and the brazing material will not rise sufficiently. Therefore, before the rapidly rising portion leaks out from the opening of the attachment hole, all the portions with less flow resistance below the flow resistance portion are uniformly filled with brazing material.
[実施例] 本発明の一実施例について説明する。[Example] An embodiment of the present invention will be described.
第1図イは本実施例の端面図であつて、説明上

としてはAlロー(JIS A−4047)を使用した。 In this example, member A1 has an outer diameter of 10 mmφ and a length of
This is a 50mm bar with a mounting hole 3 with a diameter of 8mmφ and a depth of 30mm, and the material is stainless steel (SUS304).
Made in Japan. Member B5 is a bar with an outer diameter of 7.98 mm and a length of 50 mm, with an outer diameter of 7.95 mm at 20 mm from one end, and the side with the smaller diameter becomes the insertion portion 7. The material is ceramic (alumina sintered body). Raw material 9
As the material, Al low (JIS A-4047) was used.
本実施例においては、部材Bの外面の段差部が
流動抵抗部11となる。 In this embodiment, the step portion on the outer surface of member B becomes the flow resistance portion 11.

ましい。 In the comparative example, the reliability of the joint becomes very low because the filling is not uniform. On the other hand, in the examples, all the samples were uniformly filled with brazing material, and the reliability of the bonding was very high. Further, member B5 of this example was made of non-metalized ceramic, but had sufficient strength. Furthermore, it is preferable to use a ceramic material with a metalized surface as the member B, since it provides not only mechanical bonding but also chemical bonding, thereby improving bonding strength.

ようにしてもよい。 In this example, the flow resistance part was a step due to the difference in the outer diameter of the member B5, but the insertion part was shaped to become narrower toward the tip as shown in Figure 3, and the flow resistance part was formed in the mounting hole as shown in Figure 4. metal ring 4
0 is press-fitted, as shown in Fig. 5, the inner diameter of the upper part of the inner surface of the mounting hole becomes smaller toward the opening, as shown in Fig. 6, the inner diameter of the upper part of the inner surface of the mounting hole is smaller than that of the lower part. Flow resistance can be generated by using a material such as one with unevenness on the upper inner surface of the mounting hole as shown in the figure, or one with unevenness on the part of the insertion part facing the upper inner surface of the mounting hole as shown in Fig. 8. Good too.
