Abstract
Disclosed is a turbo compressor. A rotary shaft is installed in a housing to be rotatable. A bearing supports the rotary shaft to be rotatable. A bearing housing is coupled to the housing and supports the bearing. The bearing includes a journal bearing and a journal bearing safety device. The journal bearing is attached to the inner circumference of the bearing housing, and includes a gas foil bearing so as to support the load of the rotary shaft in the radial direction. The journal bearing safety device is provided in the bearing housing, and restricts the movement distance of the rotary shaft in the radial direction to be within the elastic deformation range of the journal bearing. According to this configuration, damage to the journal bearing can be prevented.
