Description
Technical Field
The utility model relates to an engine adjustment sheet amplitude reduction structure belongs to radome fairing structural design technical field in the aircraft structure.
Background
The engine fairing is used for adjusting airflow and reducing the resistance of an airplane in the air, the fairing is generally in a streamline design, the airflow can smoothly pass through, and meanwhile, the fairing can protect a pipeline, a casing and a core machine of an engine and avoid being exposed outside and damaged by collision. The engine of the military engine is generally arranged in a machine body, an engine fairing is connected with a tail frame of the machine body, a circle of adjusting sheets are arranged at the tail part of the fairing, the adjusting sheets are pressed into a ring like fish scales, the fish scale adjusting sheets can be expanded to facilitate the installation of the engine, and the fish scale adjusting sheets can be contracted and pressed on the engine to play a role in rectification after being installed. However, since the adjustment sheet is connected only to the cowl to form a cantilever state, the adjustment sheet is likely to be damaged due to vibration caused by turbulence.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an amplitude structure is fallen to engine adjustment piece to reduce the range of the vibration of adjustment piece, reduce the impact of adjustment piece and engine.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
an amplitude reducing structure of an engine adjustment sheet comprises a steel wire rope, a hoop plate and a joint;
the hoop plate is connected with the adjusting sheet by a rivet, and the joint is riveted with the adjusting sheet at the lowest end of the amplitude reducing structure;
the steel wire rope passes through the hoop plate of each adjusting plate and is gathered at the joint.
Furthermore, the head and the tail of the steel wire rope are sleeved with a sleeve respectively.
Furthermore, the steel sleeve ring penetrates through the joint, the steel wire rope penetrates through the joint along the steel sleeve ring, and the steel wire rope penetrates through the sleeve.
Further, each hoop plate is connected to a single tab with 4 rivets.
Furthermore, the hoop plate and the joint are made of stainless steel.
Further, the steel wire rope forms a lantern ring structure from head to tail.
The utility model discloses simple structure, simple to operate, wire rope control range is big, and the suitability is strong, can effectively restrict the trimmer vibration range, reduces the collision dynamics.

The hoop plate 2 is connected with the adjusting sheet by 4 rivets, the joint 3 is riveted with the adjusting sheet at the bottom, and the steel wire rope 1 penetrates through the hoop plate 2 and finally converges at the joint 3. The steel wire rope 1 forms a lantern ring from head to tail, penetrates through the joint 3, adjusts the tightness, is hooped by the sleeve, and finally forms an adjusting piece amplitude reducing structure.
As shown in fig. 1-2, the utility model discloses a structure part simple structure, the hoop board is the sheet metal component, and the joint is the machine and adds a, and concrete production process is as follows:
a. designing and producing a set of dies, and producing a hoop plate 2 by using a rubber female die deep drawing process;
b. producing the joint 3 by a machining process;
c. the steel wire rope 1 passes through the hoop plate 2 on each adjusting plate and is sleeved with a sleeve 5 from head to tail;
d. the steel sleeve ring 4 penetrates through the joint 3, the steel wire rope 1 penetrates through the joint 3 along the steel sleeve ring, and then penetrates through the sleeve 5;
e. the steel wire rope 1 is adjusted to a proper tightness, and then the steel lantern ring 5 is pressed tightly.
Finally, an engine trim plate amplitude reduction structure is obtained.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
