CASING SUPPORT FOR HORIZONTAL-AXIS CASINGS EXPANDING IN OPERATION, IN PARTICULAR FOR TURBOMACHINE NGS

摘要

TITLE Casing Support For Horizontal-Axis Casings Expanding In Operation, In Particular For Turbo-Machine Casings. A support structure for and connected with the casing of a rotary machine operating on a horizontal axis includes a pair of vertically extending non-articulated multiple bar type pendulum supports located at opposite sides of the casing, the lower ends of the pendulum supports being secured to a support base and the upper ends to the lower half of the casing which is divided horizontally along its midplane. Vertically extending adjustable sprung supports are also provided between the base and the lower half of the casing at opposite sides of` the latter for relieving the load imposed by the machine on the pendulum supports. In order to fix the axis of the machine casing in a horizontal plane but yet permit movement in a vertical plane, a pin element projecting downwardly from the lower half of the casing in a vertical plane through the machine axis is slidably engaged within a tubular member carried by a horizontal membrane supported by the base. In order to permit torsion and/or axial expansion of the casing, a transverse metallic sheet assembly which is either slotted or provided with cut-outs extending radially of the machine axis is disposed in a radial plane of the casing beneath the latter, the upper end of this sheet assembly being secured to the lower casing half and the lower end to the base.
