Abstract
The utility model provides an axial symmetry thrust vectoring nozzle adjustment sheet gasket coupling mechanism, this mechanism mainly includes the connecting plate, the vice spout of ball, the ball auxiliary connecting rod, clamp bolt, an elastic element, the gasket, the adjustment sheet, the vice spout rigid coupling of ball is on the adjustment sheet, the ball auxiliary connecting rod passes through threaded connection with the connecting plate, the connecting plate passes through bolted connection with the gasket, when the deflection of vector tangential takes place for axial symmetry thrust vectoring nozzle expansion section, the ball auxiliary connecting rod removes in the vice spout of ball, when normal direction deflection takes place, the ball auxiliary connecting rod rotates in the vice spout of ball, thereby realize when axial symmetry thrust vectoring nozzle vector deflects being connected and press the sealing of adjustment sheet and gasket. The utility model has the advantages that mechanical structure is simple, with low costs, can effectively realize sealed the compressing tightly that axial symmetry thrust vectoring nozzle adjustment sheet and gasket be connected.
Description
Technical field
The utility model relates to a kind of air breathing engine axisymmetric vectoring exhaust nozzle field, particularly relates to a kind of axisymmetric vectoring exhaust nozzle adjustment sheet diaphragm seal bindiny mechanism.
Background technique
At present, air breathing engine axisymmetric Thrust-vectoring Nozzle is in conceptual phase, because axisymmetric vectoring exhaust nozzle part-structure is spliced by convergence adjustment sheet and Divergent flap, when axisymmetric vectoring exhaust nozzle convergence, expansion, deflection vector, the connection of convergence, Divergent flap and press seal are very important problems, in order to realize connection and the compression of adjustment sheet and diaphragm seal, research and develop that a kind of linkage structure is simple, the axisymmetric vectoring exhaust nozzle adjustment sheet diaphragm seal bindiny mechanism of high financial profit, good sealing effect is necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of axisymmetric vectoring exhaust nozzle adjustment sheet diaphragm seal bindiny mechanism.
A kind of axisymmetric vectoring exhaust nozzle adjustment sheet diaphragm seal bindiny mechanism, mainly comprises connecting plate (1), the secondary chute (2) of ball, ball slave connecting rod (6), hold-down bolt (7), elastic element (4), diaphragm seal (5), adjustment sheet (3).
The secondary chute (2) of ball is fixed on adjustment sheet (3), and ball slave connecting rod (6) and connecting plate (1) are threaded connection, and connecting plate (1) is connected by hold-down bolt (7) with diaphragm seal (5).
When axisymmetric vectoring exhaust nozzle extending section generation vector tangentially deflects, ball slave connecting rod (6) is mobile in the secondary chute (2) of ball, when genetic method is to deflection, ball slave connecting rod rotates in the secondary chute (2) of ball, thus the press seal of adjustment sheet and diaphragm seal when realizing axisymmetric vectoring exhaust nozzle deflection vector.
The secondary chute (2) of 2 balls be arranged on adjustment sheet (3) is arranged symmetrically with, and structure is identical.
The utility model has the advantages that linkage structure is simple, high financial profit, good sealing effect.
