ABSTRACT:
The present invention is directed to an assembled steam turbine with at least one balancing ring. The assembled steam turbine includes a shaft rotatable about an axis and a housing, defining a machine interior. The housing has first and second axially-spaced end walls, with the shaft extending through the first end wall. A first bearing and a second bearing rotatably support the shaft. The first and second bearings are axially spaced along the shaft and at least the first bearing is positioned outside the machine interior, proximate the first end wall of the housing. At least one balancing ring which has a plurality of radial holes is coaxially-mounted on the shaft outside the machine interior between the first end wall of the housing and the first bearing. A method for balancing the assembled steam turbine disclosed above includes several steps. In this process, the angular position of unbalance in the shaft is determined and one or more plugs is added to one or more of the radial holes in the first balancing ring to balance the shaft in response to the determined angular position of unbalance.
