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.

Abstract: A standard for supporting a turbine rotor and a turbine shell includes a bearing block including a housing enclosing bearing surfaces engageable by the turbine rotor. Turbine shell-arm supports are located on opposite sides of the housing, the turbine shell-arm supports each having a horizontal and one or more vertical surfaces adapted to be engaged by support arms of a turbine shell enclosing at least a portion of the turbine. An internal cooling/heating circuit is arranged to simultaneously cool or heat the bearing block and the turbine shell-arm supports to thereby reduce differential thermal growth characteristics of the turbine rotor and turbine shell.
