Summary: | 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. |
