Description
Technical field
The utility model relates to aircraft accessory technical field, particularly relates to a kind of novel rotor.
Background technology
Rotor is the prevailing lift parts of the rotary wing aircraft such as helicopter and rotary wings machine, for a long time, rotor is under the harsh conditions such as sharp pounding, high-speed operation, powerful impulsive force, and all can occur loosening and obscission, therefore people just rotor are provided with a Self tightening device, but when motor brakes suddenly time, can be too fast because of motor brake, cause rotor automatically to exit, cause and come off or loosen, cause the out of control of aerocraft, cause unnecessary loss.
Therefore, be badly in need of providing a kind of novel rotor, to solve the deficiencies in the prior art.
Summary of the invention
The utility model provides a kind of novel rotor for overcoming above-mentioned defect, is provided with two Self tightening devices in rotor, and rotor, when high speed rotating or motor are braked suddenly, can not loosen or come off, and adds comformability and the safety performance of rotor.
For achieving the above object, the utility model adopts following technical scheme.
A kind of novel rotor, comprise rotor head axle center and be fixedly arranged on the advancing rotor sheet at two ends, described rotor head axle center and rear row rotary blade, be provided with from jack panel in described rotor head axle center, the top cover in described rotor head axle center is provided with self-tightening nut.
More preferably, describedly in jack panel, the spin-ended step of ring-type is provided with.
More preferably, the spin-ended step of described ring-type is supported mutually with described self-tightening nut.
More preferably, the described inside face from jack panel is provided with ring shaped thread.
More preferably, described from jack panel and described rotor head axle center one-body molded.
More preferably, the inside face of described self-tightening nut is provided with ring shaped thread.
More preferably, described self-tightening nut and described rotor head axle center removably connect.
More preferably, described advancing rotor sheet and described rear row rotary blade and described rotor head axle center one-body molded.
The utility model discloses a kind of novel rotor, comprise rotor head axle center and be fixedly arranged on the advancing rotor sheet at two ends, described rotor head axle center and rear row rotary blade, be provided with from jack panel in described rotor head axle center, the top cover in described rotor head axle center is provided with self-tightening nut, compared with prior art, be provided with from jack panel in the rotor head axle center of novel rotor of the present utility model, top is covered with again self-tightening nut, for the rotor of High Rotation Speed provides duplicate protection, even if motor sudden stop, when running into strong motion or intense impact, rotor also can not come off or loosen, safety for aircraft provides the protection of many one decks, and structure is simple, cost is low, be applicable to large-scale promotion application.
Accompanying drawing explanation
With accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of novel rotor of the present utility model.
Detailed description of the invention

Embodiment 1
As shown in Figure 1, a kind of novel rotor, comprise rotor head axle center 1 and be fixedly arranged on the advancing rotor sheet 2 at two ends, described rotor head axle center 1 and rear row rotary blade 3, be provided with in described rotor head axle center 1 from jack panel 4, the top cover in described rotor head axle center 1 is provided with self-tightening nut 5, turning cylinder is socketed with from jack panel 4 and self-tightening nut 5 while of connection, revolution speed is faster, the speed that advancing rotor sheet 2 and rear row rotary blade 3 rotate is faster, S. A. with just lock tighter from jack panel 4 and self-tightening nut 5, for the rotor of High Rotation Speed provides duplicate protection, even if motor sudden stop, when running into strong motion or intense impact, rotor also can not come off or loosen, safety for aircraft provides the protection of many one decks.
More preferably, in described jack panel 4, be provided with the spin-ended step of ring-type, when S. A. rotates to the position of the spin-ended step 6 of ring-type, be locked into the tightest state, serve the effect of protection S. A., avoid excessively being locked or twisting off S. A..
More preferably, the spin-ended step of described ring-type is supported mutually with described self-tightening nut 5.
More preferably, the described inside face from jack panel 4 is provided with ring shaped thread, rotates more inward, is locked tighter.
More preferably, described one-body molded from jack panel 4 and described rotor head axle center 1.
More preferably, the inside face of described self-tightening nut 5 is provided with ring shaped thread.
More preferably, described self-tightening nut 5 removably connects with described rotor head axle center 1, is convenient to assembling, once infringement, can change.
More preferably, described advancing rotor sheet 2 and described rear row rotary blade 3 one-body molded with described rotor head axle center 1, make simple and convenient.
Compared with prior art; be provided with from jack panel in the rotor head axle center of novel rotor of the present utility model; top is covered with again self-tightening nut; for the rotor of High Rotation Speed provides duplicate protection, even if motor sudden stop, run into strong motion or impact time, rotor also can not come off or loosen; safety for aircraft provides the protection of many one decks; and structure is simple, cost is low, is applicable to large-scale promotion application.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
