Title (EN) UNBALANCE DETECTING DEVICE AND UNBALANCE DETECTING METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE DÉTECTION DE BALOURD
(JA) アンバランス検出装置、および、アンバランス検出方法
Abstract:
(EN) In a turbo cartridge including: a rotor formed by connecting a turbine wheel and a compressor wheel to each other via a shaft; and a bearing housing that houses a bearing for rotatably supporting the rotor, this unbalance detecting device detects unbalance of the rotor. The unbalance detecting device is provided with a sound pressure sensor that can detect vibrations during rotation of the rotor, by measuring, in a non-contact manner, a sound pressure generated by the vibrations during rotation of the rotor.
(FR) Une cartouche de turbo comprend un rotor formé par raccordement d'une roue de turbine et d'une roue de compresseur l'une à l'autre par l'intermédiaire d'un arbre; et un logement de palier qui renferme un palier destiné à soutenir de manière rotative le rotor, ce dispositif de détection de balourd détectant le balourd du rotor. Le dispositif de détection de balourd est pourvu d'un capteur de pression sonore qui peut détecter des vibrations pendant la rotation du rotor, en mesurant, de manière sans contact, une pression sonore générée par les vibrations pendant la rotation du rotor.
(JA) タービンホイールとコンプレッサホイールとをシャフトで結合した回転体と、回転体を回転可能に支持するベアリングを収容するベアリングハウジングと、からなるターボカートリッジにおける回転体のアンバランスを検出するためのアンバランス検出装置であって、回転体の回転時における振動により生じる音圧を非接触で計測することにより、回転体の回転時における振動を検出可能な音圧センサを備える。
