Abstract
The utility model discloses a mechanical rotating actuator. The mechanical rotating actuator comprises an external barrel, wherein a left rocking arm and a right rocking arm, which are in static connection with the external barrel, are respectively arranged at two ends of the external barrel; the lower part of each of the left rocking arm and the right rocking arm is of a hollow cylindrical structures and is coaxial with the external barrel; a left bearing and a right bearing are respectively sleeved on the outer ends of the left rocking arm and the right rocking arm; and the left bearing and the right bearing are supported by bearing blocks. The mechanical rotating actuator also comprises a piston rod which passes through a coaxial cylindrical structure composed of the left rocking arm, the external barrel and the right rocking arm; a pin 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 external barrel; a free end of the pin slides in the guide groove; and the axis of the guide groove is not parallel to that of the external barrel. According to the mechanical rotating actuator, the axial movement of the piston rod is directly converted into the rocking of the rocking arms through the rotation movement of the external barrel, so that the requirement on the space of the installation position of the rotating actuator is greatly reduced.
Description
Technical field
The utility model belongs to the actuating device that a kind of aircraft rudder surface is handled, and specifically, discloses 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, simple in structure due to it, 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 left and right) 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.
The utility model content
The purpose of this utility model is, adapts to the reality needs, and a kind of mechanical type rotating actuator is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model 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 static connection with it, 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 pin of interference fit with it, the surface of described urceolus is provided with guide groove, the free end of described pin slides in described guide groove, the axis of described guide groove and described urceolus axis are not parallel.
Connecting portion with urceolus on described left rocking arm and right rocking arm is outer-hexagonal, and the junction with left rocking arm and right rocking arm on described urceolus is interior Hexagonal jacket.
The beneficial effects of the utility model are:
1. directly the axial motion of 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 the design of change urceolus guide groove.
Description of drawings
Fig. 1 is external structure schematic diagram of the present utility model.
Fig. 2 is the longitudinal profile schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
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 static connection with it, 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 pin 4 of interference fit with it, 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, 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 right Rocker arm 5 is outer-hexagonal, and the junction with left rocking arm 2 and right Rocker arm 5 on 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 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 pin 4 between piston rod 7 and left and right rocking arm will keep certain lubricating, to reduce as much as possible interstructural cliding friction.
Can handle the needs of deflection rule according to rudder face, calculate the relation function between piston rod longitudinal travel and the rocking arm anglec of rotation, then the shape that designs urceolus guide groove 8 gets final product to meet the demands.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
