本発明は、ターｌチャージャに用いるコンゾレツサホイ

リアランスに相当する偏心を生じて超精密なバランスを
得にくくなる不都合を伴う。Conventionally, in a turbocharger, a shaft hole is generally formed in the compressor wheel and a turbine shaft is fitted into the shaft hole, but in this case, the compressor case and turbine shaft are first assembled with wood before being assembled. Temporarily assembled/? When lancing is performed, it is common to use a loose fit to facilitate attachment and detachment, but as a result, eccentricity corresponding to the clearance of the loose fit occurs, making it difficult to obtain ultra-precise balance.
又、嵌合をテーパ軸とチー・ゼ穴とで行う方法もあるが

に対する軸方向の嵌合深さがテーパぞによって規制され

向位置にばらつきを生ずる不都合を伴う。There is also a method of fitting between a tapered shaft and a cheese hole, but in this case, the depth of fit in the axial direction of the conzoresor wheel to the turbine shaft is regulated by the taper groove; If the holes are not machined with high precision, there will be an inconvenience that variations will occur in the axial position.
本発明は、かかる不都合を解消した装置を提供すること

して成る。SUMMARY OF THE INVENTION An object of the present invention is to provide a device that eliminates such inconveniences, and in which a shaft hole is formed in a compressor case and a turbine shaft is fitted into the shaft hole, An arcuate bulge is formed on either the surface or the outer circumferential surface of the turbine shaft to provide a tightening margin.

形成した。Although the above is not particularly different from the conventional type described above, according to the present invention, either one of the inner circumferential surface of the shaft hole (6) and the outer circumferential surface of the turbine shaft 7N51, for example, as shown in the second figure, the turbine shaft ( 5) or the shaft hole (6) as shown in the third figure.
An arcuate bulge QQI was formed on the inner circumferential surface of the cylinder to obtain a tightening margin.

According to this, both (1) and (5) are tightly fitted in the bulge 4, but when the bulge α is formed into an arc shape as in the present invention. are both (1)
(5) can be easily inserted and removed, and the other member always comes into contact with the bulged portion QQI over its entire circumference, making it easier to obtain concentricity.

確実に取付けられる効果を有する。As described above, according to the present invention, a bulge is formed between the inner peripheral surface of the shaft hole formed in the compressor wheel and the outer periphery of the turbine shaft that fits into the shaft hole for obtaining a tightening margin, The compressor wheel and turbine shaft are tightly fitted together, and there is no eccentricity of the wheel unlike in the conventional case where both are fitted with all the clearance, and since the bulge is formed in an arc shape, it is easy to insert and remove the two. It is relatively easy to do regardless of the tightening and fitting, and after temporarily assembling and balancing, it does not interfere with the work of disassembling the two and assembling them with wood. The other member is always in contact with the bulge over its entire circumference, ensuring concentricity, making it possible to obtain an ultra-precise nose lance, and further fitting with the tapered shaft and the chi A hole. This method has the effect that the fitting depth of the compressor wheel to the turbine shaft is not restricted, and it can be reliably attached to a predetermined axial position by the positioning member.
