Abstract
The invention discloses a mechanical rotation actuator. The mechanical rotation actuator comprises an outer cylinder and a piston rod, wherein a left rocker arm and a right rocker arm are respectively in static connection with two ends of the outer cylinder; the lower parts of the left rocker arm and the right rocker arm have hollow cylindrical structures; the left rocker arm and the right rocker arm are coaxial with the outer cylinder; a left bearing and a right bearing which are supported by a bearing block are respectively sleeved at outer ends of the left rocker arm and the right rocker arm; the piston rod penetrates through a coaxial cylindrical structure which is formed by the left rocker arm, the outer cylinder and the right rocker arm; a pin which is in interference fit with the piston rod is arranged on the surface of the piston rod; a guide groove is formed in the surface of the outer cylinder; a free end of the pin slides in the guide groove; and an axis of the guide groove is not parallel to that of the outer cylinder. According to the mechanical rotation actuator, the axial motion of the piston rod is directly changed into the swinging motion of the rocker arms through the rotational motion of the outer cylinder, so that the space requirement on the mounting position of the rotating actuator is greatly reduced.
Description
Technical field
The invention belongs to the actuating device that a kind of aircraft rudder surface is handled, specifically, disclose a kind of mechanical type rotating actuator.
Background technology
The aircraft rudder surface maneuvering system mainly is comprised of three parts: handle link (chaufeur, automatic operation system etc.), transmission link (actuating device of each rudder face of aircraft) and handled link (aircraft rudder surface), wherein the part of most critical is actuating device.Therefore, the rudder face maneuvering system is divided into again according to the difference of actuating device: mechanical type, fluid pressure type, electric and compound type.
The mechanical type maneuvering system, it is as a kind of manual control system, because it is simple in structure, functional reliability is high, be widely used in decades on all kinds of aircrafts, until still be widely used at present in the manual-operated emergent maneuvering system of the rudder face maneuvering system of some light-duty dopeies and transport plane and all aircrafts.
The actuating device of traditional mechanical operation system claims again the mechanical type actuator, generally by one or one group can be unidirectional the rocking arm of (up and down or about) motion form, have the shortcomings such as the deflection rule is single, structural weight is heavier, motion space is had relatively high expectations.Actuator is as the critical component of mechanical operation system, the quality of its mechanical specialities has directly affected the handling quality of aircraft, therefore, in the design of actuator, need elastic deformation, friction force, gap and the weight etc. that adopt novel structure and detailed design to reduce structure.
Summary of the invention
The object of the invention is to, adapt to the reality needs, a kind of mechanical type rotating actuator is provided.
In order to realize purpose of the present invention, the technical solution used in the present invention is:
A kind of mechanical type rotating actuator, comprise urceolus, described urceolus two ends are respectively equipped with left rocking arm and the right rocking arm of with it static connection, the below of described left rocking arm and right rocking arm is hollow tube-shape structure and coaxial with urceolus, the outer end of described left rocking arm and right rocking arm is respectively installed with left bearing, right bearing, described left bearing, right bearing supports by bearing seat, also comprise piston rod, described piston rod is from left rocking arm, urceolus, pass in the coaxial tubular structure that right rocking arm forms, the surface of described piston rod is provided with the with it pin of interference fit, the surface of described urceolus is provided with guide groove, the free end of described pin slides in described guide groove, and the axis of described guide groove and described urceolus axis are not parallel.
Connecting portion with urceolus on described left rocking arm and the right rocking arm is outer-hexagonal, and the junction with left rocking arm and right rocking arm on the described urceolus is interior Hexagonal jacket.
Beneficial effect of the present invention is:
1. direct axial motion with piston rod is converted to the swing of rocking arm by rotatablely moving of urceolus, thereby the space requirement of rotary actuator installation site is reduced greatly;
2. pass through to change the shape of urceolus guide groove, and then realize the variation of the relation function between piston rod longitudinal travel and the rocking arm anglec of rotation, when needs change the rotation regulation of rotary actuator, only need change the design of urceolus guide groove.
Description of drawings
Fig. 1 is external structure scheme drawing of the present invention.
Fig. 2 is the longitudinal profile scheme drawing of Fig. 1.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of mechanical type rotating actuator, comprise urceolus 3, described urceolus 3 two ends are respectively equipped with left rocking arm 2 and the right Rocker arm 5 of with it static connection, the below of described left rocking arm 2 and right Rocker arm 5 is hollow tube-shape structure and coaxial with urceolus 3, the outer end of described left rocking arm 2 and right Rocker arm 5 is respectively installed with left bearing 1, right bearing 6, described left bearing 1, right bearing 6 supports by bearing seat, also comprise piston rod 7, described piston rod 7 is from left rocking arm 2, urceolus 3, pass in the coaxial tubular structure that right Rocker arm 5 forms, the surface of described piston rod 7 is provided with the with it pin 4 of interference fit, the surface of described urceolus 3 is provided with guide groove 8, the free end of described pin 4 slides in described guide groove 8, and the axis of described guide groove 8 and described urceolus 3 axis are not parallel.
Connecting portion with urceolus 3 on described left rocking arm 2 and the right Rocker arm 5 is outer-hexagonal, and the junction with left rocking arm 2 and right Rocker arm 5 on the described urceolus 3 is interior Hexagonal jacket.
Piston rod 7 is subject to the responsive to axial force that passes over from the joystick (not shown) of maneuvering system, make piston rod produce axial motion, pin 4 on the piston rod 7 is with piston rod 7 side-to-side movements, pin 4 moves in the guide groove 8 of urceolus 3 simultaneously, because axis and described urceolus 3 axis of guide groove 8 are not parallel, therefore, can drive urceolus 3 and be rotated, thereby drive left rocking arm 2 and right Rocker arm 5 swings.
The contact surface that reaches between guide groove 8 and the pin 4 between piston rod 7 and the left and right rocking arm will keep certain lubricating, to reduce as much as possible interstructural cliding friction.
Can handle according to rudder face the needs of deflection rule, calculate the relation function between piston rod longitudinal travel and the rocking arm anglec of rotation, the shape that designs again urceolus guide groove 8 gets final product to meet the demands.
What embodiments of the invention were announced is preferred embodiment, but is not limited to this, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and variation; but only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
