CASING SUPPORT STRUCTURE FOR HORIZONTAL-AXIS MACHINE

摘要

A composite support structure for the casing of a rotary machine comprising coupled turbine and compressor units includes a pair of non-articulated multiple bar type pendulum supports upstanding on a support base at opposite sides of and secured to the casing. The load imposed by the casing on the pendulum supports is relieved by a system of vertical adjustable sprung supports extending between the casing and support base, and a pin projecting downwardly from the casing in alignment with a vertical plane through the machine axis is secured to a horizontally positioned flexible membrane which likewise is secured to the support base for securing the casing against movement in any and all directions in a horizontal plane but permitting expansion in a vertical direction. A transverse metallic sheet either slotted or provided with cut-outs is secured between the underside of the casing and support base and accommodates torsion and/or axial expansion of the casing.
