COMPENSATOR OF RELATIVE DISPLACEMENT OF INTERNAL AND EXTERNAL TURBOMACHINE CASINGS

摘要

FIELD: machine building.SUBSTANCE: compensator comprises a hollow element passing through internal and external casings. The hollow element is rigid and is fixed on the internal casing. A resilient plate is rigidly fixed on the outer surface of the hollow element on the external casing side and is fitted with a through hole for it in the central part. The resilient plate is a generatrix of the turbomachine flow section and along the perimeter is enclosed in a rim mounted in the cavity whose lower and side walls are formed by the surfaces of the external casing. On top the said cavity is closed by a cover fixed at the external casing. The rim can travel in the resilient plate plane.EFFECT: invention allows for the reduction of weight and dimensions of a compensator, increases the range of shift displacements of casings in respect to each other along with keeping sufficient sealing level in the place of a movable joint.2 dwg
