Abstract
A rotating machine and a method of assembly thereof is provided. The machine is a multi-stage rotating machine, such as a compressor, having a common shaft. The proposed method involves consecutively assembling the multiple stages. For each consecutive stage, the proposed method comprises mounting an impeller around a shaft along a tapered surface of contact on said shaft. Subsequently, the method includes applying a radially acting hydraulic pressure on said impeller to radially expand said impeller about an axis of said shaft. An axially acting hydraulic pressure is applied on said impeller to move said impeller relatively longitudinally along said tapered surface on the shaft. Subsequently, the method includes relieving said hydraulic pressures to cause said impeller to shrink radially and securely fit on to said shaft.
