STATOR FRAME OF TURBOMACHINE Russian patent published in 2008 - IPC F01D11/24 F01D25/26 

FIELD: mechanical engineering.

SUBSTANCE: stator frame of the turbo machine consists of case and ring support on the internal surface of the case, at that supports are separated from the case, but attached to it by fixing devices and assembled around circle sectors. Supports are equipped with one-type hooks with expanded end portions, at that grooves, cut in the hooks, oppose each other and retain at least two rings. The rings consist of sealing rings alternating with stator rings, latter bear fixed blades. Stator rings are connected to supports by elements radially assembled over the external side of supports. The stator ring is secured to each of the supports, while the supports are distributed as circle rows in a number equal to the specified number of stator rings. The seal rings have end portions that are either assembled on the stator ring portions, attached to hooks, or enter into the hook grooves.

EFFECT: simplification of the design and manufacture of a turbo machine frame; increasing the operating life of a stator.
