Abstract (en)
[origin: US4860418A] A method of assembling a rotor of a steam turbine constituted by disks (2) shrunk onto a shaft, the disks (2) being provided with cavities (4) facing one another and having female pegs (5) disposed in the cavities in one disk (2) and male pegs (6) disposed in the facing cavities (4) of an adjacent disk (2) with each of the disks (2) being shrunk on while disposing the male pegs (6) of the disks into the female pegs (5) of the already shrunk-on adjacent disk, the method being characterized in that spacers (12) are provided in the female pegs (5) prior to inserting the male pegs (6) in the female pegs (5) so that the male pegs (6) do not come into contact with the female pegs (5), with the spacers (12) subsequently being removed.
