ABSTRACT:
Mounting arrangement for turbomachines, especially steam turbines having a plurality of coaxially juxtaposed turbine states with shafts rigidly coupled to one another to form a shaft line, includes respective step-shaped projections formed on support lugs of turbine stage housings and jutting axially outwardly and with a step-shaped upwardly offset setback axially inwardly adjacent the projections while forming a horizontal bottom surface serving as a support and guide surface; the respective mount housing having support flanges gripping under the support lugs at both sides of the shaft in accordance with the position of the support lugs, the support flanges having a depression for accommodating therein the stepshaped projection and having a stepshaped raised rim axially adjacent the stepshaped projection for engaging in the setback of the support lug; mutual engagement of the projection in the depression, and the raised rim in the setback providing clearance sufficient to form laterally accessible gaps; adjustment and slide shims insertable in the gap between a roof surface of the raised rim and a bottom surface of the setback for the purpose of slidable height positioning, the shims being securable in position thereof; the support lugs being secured against lifting forces and moments in a set height position by means of locks detachably fastened to a cover surface of the support flanges and engaging the stepshaped projections of the support lugs by means of lock projections having contact surfaces which are adjustable in height.
