Abstract
The utility model relates to an adopt motor to operate aircraft trailing edge flap control system's flexible axle drive arrangement as drive arrangement. The motor driving device is connected with the next-stage transmission device by using a flexible shaft, the inner wall of one end of the flexible shaft is provided with inner teeth, the outer wall of the other end of the flexible shaft is provided with outer teeth, and the end of the inner teeth is meshed with the outer teeth of the motor output shaft and is fixed by a sheath fastener; the external teeth are engaged with the internal teeth of the next stage of transmission and are fixed by a sheath fastener. The utility model provides a carry out the power transfer problem in less space, owing to do not adopt the hard axle to carry out the necessary many poles of power transfer and connect, reach necessary pole connecting device within a definite time, so transmit the precision and obtain improving. In the aeronautical engineering, a precedent that a flexible shaft is used for operating the load exists, but the flexible shaft and the flexible shaft are all operated by small loads. And the utility model discloses a flexible axle transmission high rotational speed, low moment of torsion have set up the transmission of reasonable reduction ratio for next stage, both can be by this transmission output low rotational speed, high moment of torsion, and its output is enough to overcome the great pneumatic load of aircraft.
Description
Technical field: the utility model relates to a kind of flexible axle actuating device that adopts motor as the airplane trailing edge flap maneuvering system of actuating device operating aircraft wing flap folding and unfolding.
Background technology
Coming the folding and unfolding of operating aircraft wing flap with motor as actuating device is the manipulation form that multiple model aircraft adopts.Its motor drive mostly is arranged on the fuselage plane of symmetry.And motor drive is to connecting with transmission shaft between next stage driving device (generally being arranged in respectively on the wing flap of the left and right sides).Motor and hard axle gear mesh, another termination next stage driving device of hard axle, but, motor drive and next stage driving device are not in one plane, motor drive to next stage driving device connects with a hard axle and transmitting movement is difficult to realize, must arrange therebetween several hard also in addition necessary side steering can reach the purpose of transmitted power.If the structure space of aircraft is bigger, this connection mode will not have difficulties.To the aircraft of highly dense layout, because structure space is very little, the output shaft from motor drive to the next stage driving device will be difficult to adopt rigid connection mode.
Summary of the invention: the flexible axle actuating device that the purpose of this invention is to provide a kind of airplane trailing edge flap maneuvering system of in the little space of structure, using.Technical solution of the present invention is, uses flexible axle to be connected between motor drive and next stage driving device, and an end inwall of flexible axle has internal tooth, and the outer wall of the other end has external tooth, and the external tooth of interior increment and motor output shaft meshes, and fixes with the sheath fastener; The internal gearing of external tooth and next stage driving device, and fix with the sheath fastener.The invention solves in less space and carry out the power problem of transmission, transmit necessary many bar connections owing to not adopting hard axle to carry out power, and connecting device between necessary bar, so transmitting accuracy is improved.In aeronautical engineering, the precedent of using flexible axle to handle load is arranged, but all belong to the manipulation of less load.And the present invention transmits high rotating speed, low torque power by flexible axle and is provided with the driving device of rational reduction ratio to next stage, both can be by this driving device output slow speed of revolution, high torque power, and its horsepower output is enough to overcome the bigger aerodynamic loading of aircraft.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Use flexible axle 3 to be connected between motor drive 1 and next stage driving device 2, an end inwall of flexible axle 3 has internal tooth 4, and the outer wall of the other end has external tooth 5, and the external tooth 6 of internal tooth 4 ends and motor output shaft meshes, and fixes with sheath fastener 8; External tooth 5 meshes with the internal tooth 7 of next stage driving device 2, and fixing with sheath fastener 9.
