Abstract
A method for assembling a turbo-machine of the type comprising a stator housing supporting guide vanes and a rotor having blade discs. According to the method, the stator housing is placed with its axis vertically oriented on a base member which supports the housing both in the vertical and in the horizontal direction. Guide vanes and blade discs are alternately placed in the housing with the guide vanes being secured to the interior of the housing and the blade discs being supported in stacked relationship with interleaved spacing rings on the base member. The stack of blade discs is then secured together as by through bolts passing through aligned apertures in the blade discs. Thereafter, the rotor comprising the assembled blade discs and spacing rings is centered relative to the stator housing. The interconnected stator housing and assembled rotor are then lifted from the base member and moved to a horizontal position. The invention also includes apparatus for interconnecting the rotor and the stator during the assembly operation, and also includes a turbo-machine constructed in accordance with the above-described method.
