るのが現状である。2. Description of the Related Art In general, small superchargers are widely used for supercharging in internal combustion engines for vehicles, ships, and land machines. At present, the importance of superchargers is increasing, especially as part of energy saving measures and exhaust emission measures.
しかるに、従来の小形過給機はタービンケーシ
ングの耐熱性の点で問題があつた。以下、添付図
面によつてその問題点を説明する。 However, conventional small superchargers have had problems with the heat resistance of the turbine casing. The problems will be explained below with reference to the accompanying drawings.
第１図は従来の小形過給機の一例を示す側断面
である。 FIG. 1 is a side sectional view showing an example of a conventional small supercharger.

ケーシング６が設けられ、回転軸２の他端に固設
されたブロワ翼車８を回転自在に保持する。 As shown in FIG. 1, reference numeral 1 denotes a bearing chamber, which rotatably supports a rotating shaft 2. As shown in FIG. A turbine casing 3 is provided at one end of the bearing casing 1, and a turbine impeller 5 fixed to one end of the rotating shaft 2 is rotatably held therein. A blower casing 6 is provided at the other end of the bearing chamber 1, and rotatably holds a blower impeller 8 fixed to the other end of the rotating shaft 2.
このような過給機によれば、タービンケーシン
グ３に高温ガスを入れてタービン翼車５を回転さ
せることにより、回転軸２を介してブロワ翼車８
を回転させ、ブロワケーシング６から圧縮空気を
送給することができる。 According to such a supercharger, by introducing high temperature gas into the turbine casing 3 and rotating the turbine wheel 5, the blower wheel 8 is heated via the rotating shaft 2.
can be rotated to supply compressed air from the blower casing 6.
しかしながら、タービンケーシング３に入れる
ガスの温度が高い場合に、熱変形の発生という問
題がある。 However, when the temperature of the gas introduced into the turbine casing 3 is high, there is a problem in that thermal deformation occurs.

きるが、局所的な酸化剥離と熱変形が認められる
こともある。 If the supercharger is for a diesel engine, the temperature of the exhaust gas is below 750-800℃, so by using FCD40 material (spheroidal graphite cast iron) for the turbine casing 3, thermal deformation can be almost prevented. , local oxidation peeling and thermal deformation may be observed.

るものである。 In addition, in the case of gasoline engines, the temperature of the exhaust gas may exceed 1000°C, so Niresist material containing 20% nickel is normally used for the turbine casing 3, but even with this When used at 1000°C, thermal deformation of the turbine casing 3 is observed. Moreover, the material cost of Niresist material is 2.8 times higher than that of FCD40 material.

Furthermore, the weakness of ceramic material against mechanical shocks can be reinforced by covering the scroll parts 9, 10 with metal plates 11, 12. In other words, when the scroll parts 9 and 10 are wrapped with plates 11 and 12 made of a metal material that is sensitive to high temperatures but has high mechanical strength and tenacity at low temperatures, the outer surfaces of the scroll parts 9 and 10 are made of ceramic material with excellent heat insulation. Since the metal plates 11 and 12 are kept at a low temperature due to their properties, the strength and rigidity of the metal plates 11 and 12 are not reduced. Therefore, the metal plates 11 and 12 are
This protects the ceramic scroll parts 9 and 10, which have little elongation and are susceptible to impact.
