Abstract
An unbalance detection device for detecting unbalance of a rotor of a turbo-cartridge which includes the rotor including a turbine wheel and a compressor wheel coupled via a rotational shaft and a bearing housing accommodating a bearing which supports the rotor rotatably, includes: a turbine-side housing member accommodating the turbine wheel; a compressor-side housing member accommodating the compressor wheel; a support mechanism configured to nip and support the turbo-cartridge from both sides by pressing at least one of the turbine-side housing member or the compressor-side housing member toward the turbo-cartridge; a vibration insulator interposed in each of a gap between the turbine-side housing member and the turbo-cartridge and a gap between the compressor-side housing member and the turbo-cartridge; and a vibration sensor installed so as to be contactable with the bearing housing, the vibration sensor being capable of detecting vibration upon rotation of the rotor.
