Abstract: Rotor support structures for industrial machines are disclosed. The support structures may include a rigid base component including a top portion, a slide plate positioned above the rigid base component, and a bearing housing for a rotor, coupled to the slide plate. The bearing housing and the slide plate may be configured to slide or move over the rigid base component. The support structure may also include a plurality of retention blocks coupled to the bearing housing. Each of the plurality of retention blocks may include a moveable retention pin positioned through each of the plurality of retention blocks. The axial movement of the bearing housing and slide plate may compensate for thermal expansion of a turbine shell and/or may reduce vibrations of the rotor and bearing housing during operation of the industrial machines.
