DEVICE FOR CONNECTION OF HOUSING OF GAS TURBINE ENGINE Russian patent published in 1998 - IPC

FIELD: connection of housing of aircraft gas turbine engines. SUBSTANCE: during operation of engine, inertial forces and torque from mating portion of inner housing are transmitted to outer housing by means of projections with grooves of slide blocks and pins. Isolation of housings in axial and radial directions for compensation for thermal expansion and axial displacement is ensured due to absence of limitation in axial direction in joint of slot and slide block and due to radial clearance in radial direction. Inaccuracy in mounting the joint unit of housing is compensated for due to eccentric position of axes and radial pin and cylindrical journal by turning the pin in cylindrical radial bore followed by locking it by means of splined bush and bolts. EFFECT: reliable isolation of engine housings; facilitated assembly of housing. 3 dwg
