Abstract
A centrifugal compressor has at least one stage with its own impeller shaft and a gear train for driving the impeller shaft. The gear train includes a plurality of meshing parallel shaft gears comprising two input gears either of which can receive drive from a prime mover. The ratio of the number of teeth of the input gears is such that the relative shaft speeds of the input gears are 5n: 6N where n is 1 or 2 and N is 1 or 2.
