ABSTRACT:
Apparatus is disclosed for reducing humping in steam turbines, where the steam turbine includes a rotor assembly, rotatably mounted to a foundation, a stator assembly, positioned about said rotor assembly, an outer cylinder, to which the stator assembly is attached, which outer cylinder being divided into a cover half and a base half. The apparatus for reducing humping includes a plurality of support towers attached to the foundation and a plurality of support paws attached to the base half, wherein each support paw is mounted on a support tower. Each of said support paws is shown to include first and second sidewalls, each attached along one end to the base half and a top wall positioned between the side walls. The top wall and the first and second side walls define a cavity, whereby a portion of the support tower fits within the cavity. The division between the cover and base halves defines a joint. The first and second sidewalls are formed such that they extend beyond the joint. The top wall defines a lower surface. Such lower surface is preferably coplanar with the joint.
