TURBINE GUIDE - VANE ASSEMBLY SECTOR UNIT IN HOUSING Russian patent published in 2008 - IPC F01D25/24 

FIELD: mechanical engineering; turbines.

SUBSTANCE: proposed sector unit of guide vane assembly in turbine housing has two flanges installed with their support surfaces on housing, hook getting under curvilinear edge of one of flanges to preclude centripetal displacements of sectors, movable end plate arranged between flanges and device for fastening end plate on housing. Hook is located on end plate, and end plate and turbine housing have flat support surface orientated in direction of turbine axis. End plate fastening devices contain mounting pins passing radially through turbine housing. End plate fastening devices contain mounting pins passing radially through turbine housing. End plate is fixed between turbine housing and mounting pins and it is installed on turbine housing in direction to flange provided with above indicated curvilinear edge. Other invention of said group relates to turbomachine containing said unit of sectors of guide - vane assembly.

EFFECT: facilitated mounting of sectors of guide-vane assembly on turbine housing with preservation of rigidity of joint.
