本考案は、過給機のブロワハウジングに関する
ものである。[Detailed Description of the Invention] The present invention relates to a blower housing for a supercharger.
近年、製品責任という言葉で示される様に、い
かなる不慮の事故に対しても、顧客の安全性が守
られる様な製品が要求されている。 In recent years, as indicated by the term product liability, there has been a demand for products that can protect customer safety against any unexpected accidents.
過給機においても、高速回転するインペラが破
損してハウジングを突き破り、外部へ飛び出すと
大事故を起しかねないため、万一の事故、例えば

もこれが外部へ飛び出ない構造が要求されてい
る。 In a turbocharger, if the impeller rotating at high speed breaks and pierces the housing and flies out, it can cause a major accident. There is a need for a structure that will not allow the impeller to fly out even if it is damaged due to such reasons.
特にブロワ側のハウジングは軽量化を図るた

る。 In order to reduce the weight of the blower housing in particular, aluminum alloy is generally used, but since aluminum alloy has low strength, it is difficult to protect the impeller from damage. Please note that the turbine housing is made of cast iron, so
Sufficient strength against turbine damage can be ensured.
上記ブロワ側のインペラ破損に対しての従来の
対策としては、単にハウジングの肉厚を厚くして
インペラが破損してもこれが飛び出さないだけの
強度を与える様にしている。 A conventional measure against damage to the impeller on the blower side is to simply increase the wall thickness of the housing to provide enough strength to prevent the impeller from flying out even if the impeller is damaged.
このためブロワハウジングは機能上必要な肉厚
よりも3〜5倍も厚くなつており、材料の無駄使
いおよび重量増加等の不都合があつた。これは特
に中・大型の過給機になる程、その倍率が大きく
なり、重量上問題となつている。 For this reason, the blower housing is 3 to 5 times thicker than necessary for its functionality, resulting in disadvantages such as wasted material and increased weight. This becomes a problem in terms of weight, especially as the supercharger becomes medium to large, the larger the magnification becomes.
本考案は上記のことにかんがみなされたもの
で、アルミ合金製のブロワハウジングに、リング

止できるようにした過給機のブロワハウジングを
提供しようとするものである。 The present invention was developed with the above in mind, and by casting a ring-shaped steel wire into the housing wall of an aluminum alloy blower housing,
It is an object of the present invention to provide a blower housing for a supercharger, which has improved strength against impacts without increasing the weight of the housing, and can prevent scattering when an impeller breaks.
以下本考案の実施例を図面に基づいて説明す
る。 Embodiments of the present invention will be described below based on the drawings.

の鋼線4は各リング毎に別体でもよいが、周壁形
状に沿つた形状の一体の螺線状にしてもよい。 In the figure, 1 indicates the blower side of the supercharger, 2 is a blower impeller, and 3 is a blower housing. A plurality of ring-shaped steel wires 4 are cast inside the peripheral wall of the portion of the blower housing 3 that surrounds the blower impeller 2 and includes the throat minimum cross section. The steel wire 4 may be formed separately for each ring, but it may also be formed into an integral spiral shape that follows the shape of the peripheral wall.
上記ブロワハウジング3はアルミ合金鋳物にて
構成されており、これの注湯温度は約710℃であ

ない。 Since the present invention is as described above, the impact strength of the portion surrounding the blower impeller 2 including the minimum cross section of the throat of the blower housing 3 made of a light alloy such as an aluminum alloy is improved, and the impeller 2 is It is possible to prevent this from scattering when it is damaged, and to ensure the safety of customers. Further, according to the present invention, a steel wire is used as a reinforcing member for reinforcing the blower housing 3, and the steel wire 4 is cast into the peripheral wall of the portion surrounding the blower impeller 2, so that the reinforcing member is Assembling is performed at the same time as casting of the blower housing 3, the number of man-hours required for assembling the reinforcing member is reduced, and the appearance of the blower housing 3 is not impaired by the reinforcing member.
