Description
本発明は、遠心圧縮機、過給機、および遠心圧縮機の製造方法、並びにサイレンサに関する。 The present invention relates to a centrifugal compressor, a supercharger, a method for manufacturing a centrifugal compressor, and a silencer .
本発明は、このような事情を鑑みてなされたものであり、羽根車の全部または一部が破断あるいは脱落するのに伴って案内筒の全部または一部が飛散する場合に、羽根車の全部または一部が外部に飛散する不具合を抑制することが可能な遠心圧縮機を提供することを目的とする。
また、本発明は、前述した遠心圧縮機を備えた過給機、および前述した遠心圧縮機の製造方法、並びに前述した遠心圧縮機に取り付けられるサイレンサを提供することを目的とする。
The present invention has been made in view of such circumstances. When all or a part of the guide tube is scattered as the whole or a part of the impeller is broken or dropped, the entire impeller is provided. Another object of the present invention is to provide a centrifugal compressor capable of suppressing a problem that a part of the air is scattered outside.
Another object of the present invention is to provide a turbocharger including the above-described centrifugal compressor, a method for manufacturing the above-described centrifugal compressor, and a silencer attached to the above-described centrifugal compressor .
本発明によれば、羽根車の全部または一部が破断あるいは脱落するのに伴って案内筒の全部または一部が飛散する場合に、羽根車の全部または一部が外部に飛散する不具合を抑制することが可能な遠心圧縮機を提供することができる。
また、本発明によれば、前述した遠心圧縮機を備えた過給機、および前述した遠心圧縮機の製造方法、並びに前述した遠心圧縮機に取り付けられるサイレンサを提供することができる。
According to the present invention, when all or a part of the impeller is scattered as a whole or a part of the impeller is broken or dropped, it is possible to suppress a problem that all or a part of the impeller is scattered to the outside. It is possible to provide a centrifugal compressor that can be used.
Moreover, according to this invention, the turbocharger provided with the centrifugal compressor mentioned above, the manufacturing method of the centrifugal compressor mentioned above, and the silencer attached to the centrifugal compressor mentioned above can be provided.
前述したように空気案内筒１２が取付位置から脱落すると、空気案内筒１２が仕切板１４に衝突する。この衝突によってスクロールケーシング１３ｂが軸受台２０から離間する方向の衝撃力が加わる。この衝撃力は、締結ボルト４１とフランジ部１３ｆとフランジ部２０ａの締結位置に作用する。 As described above, when the air guide tube 12 is dropped from the mounting position, the air guide tube 12 collides with the partition plate 14. Due to this collision, an impact force is applied in a direction in which the scroll casing 13b is separated from the bearing base 20. This impact force acts on the fastening position of the fastening bolt 41, the flange portion 13f, and the flange portion 20a.
本実施形態の遠心圧縮機１０によれば、スクロール部１３から離れる方向に飛散する空気案内筒１２の全部または一部が仕切板１４を収容するサイレンサケーシング１５ａに衝突すると、スクロールケーシング１３ｂを軸受台２０のフランジ部２０ａから引き離す方向の衝撃が加わる。この衝撃は、締結ボルト４１の頭部４１ａとスクロールケーシング１３ｂとの間に配置されるスペーサ５１が収縮することにより吸収される。このように、締結ボルト４１に挿入した状態で締結されるスペーサ５１を用いて、軸線Ｘ方向の衝撃を吸収することにより締結ボルト４１が破断する不具合が抑制される。よって、空気案内筒１２の全部または一部の飛散によって遠心圧縮機１０の一部に隙間が生じ、その隙間から羽根車１１の全部または一部が外部に飛散する不具合を抑制することができる。 According to the centrifugal compressor 10 of the present embodiment, when all or a part of the air guide cylinder 12 scattered in a direction away from the scroll portion 13 collides with the silencer casing 15a accommodating the partition plate 14, the scroll casing 13b is moved to the bearing stand. The impact of the direction pulled away from 20 flange parts 20a is added. This impact, the spacers 51 disposed between the head 41a and the scroll casing 1 3 b of the fastening bolt 41 is absorbed by contracting. Thus, the failure | damage which the fastening bolt 41 fractures | ruptures by absorbing the impact of an axis X direction using the spacer 51 fastened in the state inserted in the fastening bolt 41 is suppressed. Therefore, it is possible to suppress a problem that a gap is generated in a part of the centrifugal compressor 10 due to scattering of all or part of the air guide cylinder 12, and all or part of the impeller 11 is scattered outside from the gap.
本実施形態において、フランジ部２０ａは、クランプ部材６０と締結ボルト４３によって締結されており、スクロールケーシング１３ｂの軸線Ｘ方向の端面１３ｉと、凹所６０ａの軸線Ｘ方向の端面６０ｅとの間に所定の隙間６０ｃが設けられている。そして、フランジ部２０ａは、スクロールケーシング１３ｂと接触する接触面２０ｅと、圧縮空気が流通する流路１３ｈを形成するとともに接触面２０ｅよりも流路１３ｈ側に配置されるフランジ部２０ａの端面２０ｆとを接続する段部２０ｇを有する。 In the present embodiment, the flange portion 20a is fastened by the clamp member 60 and the fastening bolt 43, and is predetermined between the end surface 13i in the axis X direction of the scroll casing 13b and the end surface 60e in the axis X direction of the recess 60a. The gap 60c is provided. The flange portion 20a forms a contact surface 20e that comes into contact with the scroll casing 13b, a flow passage 13h through which compressed air flows, and an end surface 20f of the flange portion 20a that is disposed closer to the flow passage 13h than the contact surface 20e. Has a step portion 20 g for connecting the two.
このようにすることで、複数の締結ボルト４１が破断して軸受台２０のフランジ部２０ａとスクロールケーシング１３ｂとが離間してスクロールケーシング１３ｂの軸線Ｘ方向の端面１３ｉが凹所６０ａの軸線Ｘ方向の端面６０ｅが接触する場合に、段部２０ｇの存在によってフランジ部２０ａとスクロールケーシング１３ｂとの間の口開きが抑制される。更に、段部２０ｇの軸線Ｘ方向の幅ｄ６が所定の隙間６０ｄの幅ｄ５よりも広いので、連通する隙間が発生せず、口開きをより確実に抑制することができる。 By doing so, the axis X of the axis X direction of the end face 13i is a recess 60 a of the flange portion 20a and the scroll casing 13b and is scroll casing 13b spaced apart of bearing stand 20 with a plurality of fastening bolts 41 is broken When the direction end surface 60e contacts, the presence of the step portion 20g suppresses the opening between the flange portion 20a and the scroll casing 13b. Furthermore, since the width d6 of the step portion 20g in the axis X direction is wider than the width d5 of the predetermined gap 60d, no communicating gap is generated, and the mouth opening can be more reliably suppressed.
以上の説明において、クランプ部材６０は、軸受台２０のフランジ部２０ａに締結するものとしたが、他の態様であってもよい。例えば、クランプ部材６０をスクロールケーシング１３ｂのフランジ部１３ｆに締結するようにしてもよい。この場合、スクロールケーシング１３ｂのフランジ部１３ｆが軸線Ｘ方向に延びる締結穴を軸線Ｘ回りの周方向に複数有するものとなる。そして、この複数の締結穴に締結ボルト４３を締結することにより、クランプ部材６０がスクロールケーシング１３ｂのフランジ部１３ｆに締結される。また、この場合、前述した隙間６０ｃは、軸受台２０のフランジ部２０ａの軸線Ｘ方向の端面とクランプ部材６０の凹所の軸線Ｘ方向の端面との間に設けられることとなる。 In the above description, the clamp member 60 is fastened to the flange portion 20a of the bearing stand 20, but may be in another form. For example, it may be concluded clamp member 60 to the flange portion 13 f of the scroll casing 13b. In this case, the flange portion 13 f of the scroll casing 13 b has a plurality of fastening holes extending in the axis X direction in the circumferential direction around the axis X. Then, by fastening the fastening bolt 43 to the plurality of fastening holes, the clamping member 60 is fastened to the flange portion 13 f of the scroll casing 13b. In this case, the gap 60 c described above is provided between the end surface in the axis X direction of the flange portion 20 a of the bearing base 20 and the end surface in the axis X direction of the recess of the clamp member 60.
