For solving technical matters of the present utility model, the technical solution adopted in the utility model is:
A kind of universal joint cross formula aileron transmission device, this cover aileron transmission device comprises turning block, connecting rod, rocking arm, drive shaft, universal joint cross assembly and antifriction-bearing box, described turning block two ends are articulated linkage respectively, described connecting rod and one end hinged, the described rocking arm other end is connected with drive shaft, described antifriction-bearing box interference fit is installed on drive shaft two ends, and described drive shaft splits into two sections of connections as required by universal joint cross assembly.
As further improvement of the utility model, described universal joint cross assembly comprises hexagonal grooved jam nut, spring cotter, ball-headed bolt, cushion block, lining and rotating shaft, cushion block is pressed into the corresponding centre hole of drive shaft, lining, the corresponding centre hole of rotating shaft press-in drive shaft, pass cushion block, lining and rotating shaft successively with ball-headed bolt afterwards, tighten hexagonal grooved jam nut and insertion opening pin.
Wherein, in the middle part of described turning block, there is power entrance point.
Wherein, described drive shaft end has movement output point.
This mechanism carries out comformability modification on the basis of traditional four-bar linkage, and mechanism adopts a set of universal joint cross assembly that drive shaft is split connection as required, realizes propulsion source to the reliable transmission of aileron.Making full use of in the narrow and small aerofoil profile space basis of wing, drive shaft is arranged in parallel in airfoil chord plane along aileron shaft axis direction, universal joint cross assembly allows two between centers to have larger angle simultaneously, the relative displacement of diaxon can be compensated, the rotating shaft clamping stagnation problem effectively avoiding wing flexural deformation to cause.By universal joint cross number of components and layout in changing mechanism, the utility model can be applied to the different aerodynamic loading situation of different type of machines, realizes General design.
The beneficial effects of the utility model: this mechanism structure is simple, institutional adjustment is flexible, transmitting ratio is constant, and output torque variation range is large, and it is little effectively can to solve wing space, drive path length and wing flexural deformation affect the problems such as transmission accuracy, can be widely used in the aileron transmission device that installing space is limited and grow apart from transmission, mechanism is driven by single power source, and left and right aileron motion synchronicity is good, aileron both forward and reverse directions deflection symmetry is good, and response is reliable; By repacking, can according to the different aerodynamic loading situation of different type of machines, mechanism can realize designing universalization.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Following examples, only for illustration of the utility model, are not used for limiting protection domain of the present utility model.
Shown in Fig. 1, a kind of universal joint cross formula aileron transmission device of the present utility model, this cover aileron transmission device comprises turning block 2, connecting rod 3, Rocker arm 4, drive shaft 5, universal joint cross assembly 6 and antifriction-bearing box 7, turning block 2 two ends are hinged with connecting rod 3 respectively, connecting rod 3 is hinged with Rocker arm 4 one end; the Rocker arm 4 other end is connected with drive shaft 5, and antifriction-bearing box 7 interference fit is installed on drive shaft 5 two ends, and drive shaft 5 splits into two sections of connections as required by universal joint cross assembly 6.
When wherein turning block 2 rotates to a certain set direction under single power source effect, connect the motion of left linkages 3 reversing sense, then the differential deflection of left and right aileron is realized, produce the operating torque that target drone is rolled around fuselage axis, realize the motor performance or stable around fuselage axis, meet again mechanism's synchronism requirement simultaneously.In order to ensure that mechanism has good Linear transmission relation, should make between connecting rod 3 and Rocker arm 4 vertical as far as possible when steering wheel is in center position, but wing have employed large sweepback angle, Rocker arm 4 two ends have connecting bore, in one connecting bore 18, stud connection has connecting rod 3, another connecting bore 17 has assigned drive shaft 5, Rocker arm 4 two connecting bore 17 in the utility model, 18 axis and be designed with certain angle (Fig. 2 a respectively between connecting rod 3 axis and drive shaft 5 axis, Fig. 2 c), it is 0 ° between connecting bore 17 axis and drive shaft 5 axis, it is 90 ° between connecting bore 18 axis and connecting rod 3 axis, the strong rigidity of Rocker arm 4 is improved under the prerequisite meeting drive path, ensure that mechanism has constant ratio.In addition, for alleviating in target drone flight course, wing produces the rotating shaft clamping stagnation being out of shape and causing by Aerodynamic force action, aileron drive shaft 5 cuts point as required, adopt universal joint cross transmission component 6 to carry out connecting (as shown in Figure 2 b) between segmentation rotating shaft, this kind of coupler structure is compact, easy to maintenance, allow two between centers to have larger angle, the relative displacement of diaxon can be compensated.
Fig. 2 b, above-mentioned universal joint cross assembly 6 comprises hexagonal grooved jam nut 11, spring cotter 12, ball-headed bolt 13, cushion block 10, lining 14 and rotating shaft 15, cushion block 10 is pressed into the corresponding centre hole of drive shaft 5, lining 14, rotating shaft 15 are pressed into the corresponding centre hole of drive shaft 5, pass cushion block 10, lining 14 and rotating shaft 15 successively with ball-headed bolt 13 afterwards, tighten hexagonal grooved jam nut 11 and insertion opening pin 12.
