Patent ID: 8790076

Claim:
A centerline suspension arrangement for a turbine comprising: an outer casing comprising a lower half and an upper half; an inner casing comprising a lower half and an upper half; an inner casing slot formed along a longitudinal axis in the lower half of the inner casing; an outer casing slot formed in the lower half of the outer casing; a support member comprising an inner portion disposed within the inner casing slot and an outer portion extending into the outer casing slot; wherein cooperating geometries of the inner casing slot and the inner portion of the support member permit insertion of the support member inner portion into the slot in a direction of the longitudinal axis only and provide a body bound fit of the support member about the longitudinal axis effective to prevent rotation of the support member about the longitudinal axis, within constraints of an assembly tolerance, in response to dead weight and operating loads of the turbine.
