DEVICE FOR PREVENTING ROTATION OF AN INNER AIR SEAL AND A DAMPER SPRING IN A STATOR ASSEMBLY BY COMBINING A LUG WITH A SLOT OF THE DAMPER SPRING AND A CUT PORTION OF A STATOR SEGMENT

摘要

PURPOSE: A device for restricting rotation of an inner air seal is provided to prevent rotation of the damper spring or the inner air seal against the stator cluster by arranging the lug in the slot in the center of the arc segment of the inner air seal. CONSTITUTION: A stator cluster assembly(4) is composed of an inner air seal(1) mounted on a honeycomb structure by brazing, a damper spring and two or three stator clusters(3) combined with the damper spring and the inner air seal. Load of gas is applied to the circumference of the stator cluster, and rotation of the stator cluster against an inner case is restricted by a rotation restricting unit. A lug(8) is arranged in a slot in the center of the inner air seal arc segment by brazing, and combined with a slot of the damper spring to restrict rotation of the damper spring to the inner air seal. The lug is protruded forward and combined with a cut portion(18) in the stator segment through an inner air seal front(16).
