Abstract
PURPOSE: To elminate thermal deformation of the casing and prevent the phenomenon of rubbing between the casing and rotor by forming the gas extraction chambers of upper and lower casing halves such that they have difference areas and thus equalizing the rigidity of the upper and lower casing halves.
CONSTITUTION: A gas extraction chamber 3 of an upper casing half 6 is formed such that its area is smaller than that of a lower casing half 7. The area ratio of the gas extraction chamber 3 between the upper and lower casing halves 6 and 7 is determined such as to minimize the displacement of the rotor center by obtaining the thermal deformation of the flat plate with a finite element method or the like. In a front vertical plate 8 the extent l of elongation of the plate toward the outer side is calculated as l = α.T.L. The coefficient α of linear expansion and temperature T are identical for both the upper and lower casing halves 6 and 7 and vary with the representative length L.
