Description
Technical field
The invention belongs to aeronautical and space technology, and in particular to a kind of safe rocking arm of new propulsive thrust deformation protection.
Background technology
Electromechanical actuator is because its is simple in construction, good manufacturability, and reliability is high, easy to maintenance, more and more applies
The aerospace fields such as guided missile, unmanned plane, spaceship.Due to aircraft at a high speed, high motor-driven continuous development and electromechanical make
Dynamic device application field is constantly widened, and the use environment such as high acceleration, large impact, strong vibration it is also proposed more to electromechanical actuator
High requirement.
High maneuver is done in aircraft, when big reinforcing is moved, engine overall structure can deform, attached installed in engine
Near electromechanical actuator long-term use infringement electromechanical actuator, will be had a strong impact on flight safety by big propulsive thrust.
The content of the invention
The technical problem to be solved in the present invention：
Do high maneuver to solve aircraft, during big reinforcing motion, big propulsive thrust to electromechanical actuator structural damage problem,
Design the safe rocking arm of electromechanical actuator that a kind of mechanism is simple, reliability is high, has propulsive thrust deformation defencive function.
Technical scheme：
A kind of safe rocking arm of new propulsive thrust deformation protection, including it is output shaft 1, limited cover 2, torsion spring 3, copper bush 4, defeated
Go out Rocker arm 5, copper washer 6, hezagon castle nut 7, split pin 8.Safe rocking arm is arranged on one end of output shaft 1, and limited cover 2 is logical
Cross key with output shaft 1 to be connected, copper bush 4 is located between the face of cylinder of output shaft 1 and output Rocker arm 5 endoporus, the both ends point of torsion spring 3
It is not connected by limited cover 2 with the circumferentially upper uniform hole of output Rocker arm 5.The end of output shaft 1 connects hezagon castle nut 7 and opening
Pin 8, copper washer 6 is between limited cover 2 and hezagon castle nut 7.
By the both ends of torsion spring 3 insertion limited cover 2 and export in the circumferentially upper uniform hole of Rocker arm 5, the boss insertion of limited cover 2 is defeated
Go out in the U-type groove of Rocker arm 5 end, boss abuts against one end of U-type groove, torsion spring is produced certain pretightning force, and high thrust, which deforms, to be caused
When moment of torsion on output Rocker arm 5 is more than pretightning force, the boss of limited cover 2 moves in the U grooves of output Rocker arm 5 end, exports Rocker arm 5
It is appropriate to make a concession, effectively protect electromechanical actuator.
Beneficial effects of the present invention：
By the torsion spring 3 of the moment of torsion in the output certain load of Rocker arm 5 internal preset, the torque value of the pretension is more than electromechanical make
The maximum load of dynamic device, therefore in normal work, the pre-fastening moment make it that export Rocker arm 5 keeps normal synchronized with output shaft 1
Motion；When motor power, which deforms, make it that the moment of torsion on output Rocker arm 5 is more than preset value, torsion spring is further compressed, output
Rocker arm 5 is suitably made a concession, and is relatively rotated with output shaft 1.The safe rocking arm efficiently solves anti-the problem of pushing away deformation on machine,
Effectively protect the handling safety of electromechanical actuator.
Brief description of the drawings
Fig. 1 is the design structure diagram of the patent；
Embodiment
With reference to Fig. 1, technical solution of the present invention is described in detail：
The structure includes output shaft 1, limited cover 2, torsion spring 3, copper bush 4, output Rocker arm 5, copper washer 6, fluting hexagonal spiral shell
Mother 7, split pin 8.
Limited cover 2 is connected by key with output shaft 1, and copper bush 4 is located between the face of cylinder of output shaft 1 and rocking arm inner hole,
The both ends of torsion spring 3 are connected by limited cover 2 with the circumferentially upper uniform hole of output Rocker arm 5 respectively.The end of output shaft 1 connection fluting six
Angle nut 7 and split pin 8, copper washer 6 is between limited cover 2 and hezagon castle nut 7.
Deformed during installation by reversing torsion spring 3, torsion spring 3 is produced certain pretightning force, limited cover 2 is inserted at the both ends of torsion spring 3
In the circumferentially upper uniform hole of output Rocker arm 5, by selecting the limited cover 2 that torsion spring 3 inserts and diverse location on output Rocker arm 5
Hole adjusts pretightning force, and the torque value of the pretension is more than the maximum load of electromechanical actuator, after safe rocking arm installs, limited cover
In 2 U-shaped boss insertion output Rocker arm 5 end U holes, boss abuts against the one end in U holes.Therefore in normal work, the pretension
Torque make it that export Rocker arm 5 keeps normal synchronized motion with output shaft 1；To export the moment of torsion on Rocker arm 5 when high thrust deforms
During more than pretightning force, the boss of limited cover 2 moves in the U grooves of output Rocker arm 5 end, and output Rocker arm 5 suitably retreats, with output shaft
1 relatively rotates.The safe rocking arm efficiently solves anti-the problem of pushing away deformation on machine, protects the manipulation of electromechanical actuator
Safety.
