Description
Technical Field
The utility model relates to the technical field of aviation, specifically a novel rotation gyroplane pre-rotation clutch device.
Background
The autorotation gyroplane (called gyroplane for short) is a gyroplane taking an autorotation rotor as a lifting surface, propeller pushing/pulling force or other energy supply modes as advancing power, and has the characteristics of simple mechanism, high safety, low cost and the like, and the rotor of the gyroplane realizes autorotation by depending on the forward incoming flow driving during flight to provide lift force. And adopt the rotor to revolve technique in advance, drive the rotor in advance through transmission before taking off, then take off after cutting off the transmission link through the clutch, can make the gyroplane can the ray formula jump or ultrashort apart from taking off.
The existing prerotation mechanism adopts a prerotation small cylinder and a gas circuit control device, and has the disadvantages of complex system, heavy structure weight, and low safety and reliability.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve prior art's problem, provide a novel rotation gyroplane is clutch device in advance, removed little jar and gas circuit controlling means in advance on the basis of realizing original clutch function in advance, adopt inertia to get rid of the mode of tooth and realize this function, reduced the complexity and the structure weight of system in advance, improved its security and reliability.
The utility model discloses an interior axle that links to each other with rotor hub device manipulation cantilever through bearing structure, interior hub connection has the flexible axle, and it has the ring gear to open on the interior axle, and the internal ring circles through skewed tooth and outer ring gear meshing, and the external gear reciprocates along the skewed tooth of interior axle under the centrifugal force effect, moves with rotor hub device gear wheel meshing when the highest point when the external gear.
The improvement is further that during prerotation, the flexible shaft transmits power to the inner shaft to drive the inner shaft to rotate, the outer gear ring has a rotation speed difference with the inner gear ring under the inertia effect, and moves upwards along the helical teeth to be meshed with the large gear; when the pre-rotation is disconnected, the rotating speed of the outer gear ring is reduced to be lower than that of the large gear, the outer gear ring moves downwards along the helical gear and is separated from the large gear, and the pre-rotation clutch function is realized.
The bearing structure comprises an upper bearing, an upper bearing seat, a lower bearing and a lower bearing seat, wherein the upper part of the inner shaft is fixed with the operating cantilever through the upper bearing and the upper bearing seat, and the lower part of the inner shaft is fixed with the operating cantilever through the lower bearing and the lower bearing seat.
The utility model has the advantages that: the pre-rotation clutch has the advantages that the pre-rotation small cylinder and the gas circuit control device are removed on the basis of realizing the function of the original pre-rotation clutch, the function is realized by adopting an inertia tooth throwing mode, the complexity and the structural weight of the pre-rotation system are reduced, and the safety and the reliability of the pre-rotation system are improved.
