Adjusting device adaptive to variable nozzle of engine

Abstract

The invention belongs to the technical field of aviation machinery, and relates to an adjusting device adapting to a variable nozzle of an engine, which comprises active adjusting sheets uniformly distributed in the circumferential direction, hinges are arranged on the inner sides of the active adjusting sheets, the active adjusting sheets are connected with a retaining ring through the hinges, and the other ends of the inner sides of the active adjusting sheets are rotatably connected with one ends of push-pull rods; a driven adjusting piece is arranged between every two adjacent driving adjusting pieces, one end of each driven adjusting piece is connected with the retaining ring in a rotating mode, a limiter is arranged at the other end of each driving adjusting piece, an elastic piece is arranged at the other end of each driven adjusting piece, and the elastic pieces can slide on the driven adjusting pieces. The two ends of each stopper respectively press the elastic pieces adjacent to the stopper, the retaining ring is connected with the engine nozzle and limits axial movement of the retaining ring, and meanwhile, the adapter frame on the retaining ring is connected with the engine nozzle through the fixing frame and limits radial movement of the retaining ring.
