Abstract

A centrifugal compressor, the capacity of which can be increased with keeping the diameter of the impeller at minimum, is provided. The centrifugal compressor includes: a drive gear (); a drive shaft () protruding from one side of the drive gear () in a central axis direction of the drive gear (); a no.driven pinion gear () configured for rotation of the drive gear () to be transmitted thereto; a no.driven pinion shaft () protruding from both sides of the no.driven pinion gear () in a central axis direction of the no.driven pinion gear (); and a couple of first stage compressor sections (), each of which is provided in each end of the no.driven pinion shaft () and is configured to compress fluid by rotation of the no.driven pinion shaft ().
