In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is
The a part of embodiment of the present invention, rather than whole embodiments, based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment being obtained on the premise of not making creative work, broadly falls into the scope of protection of the invention.
As shown in figure 1, embodiments providing a kind of flexible axle, including：
Axis body 10 and flexible pipe 20；Wherein, described axis body 10 is arranged in described flexible pipe 20；
Described axis body 10 includes：Tension shaft core 102 and be successively wrapped at least two torsion in described tension shaft core
Layer 101；
Described torsion layer 101 is formed around the mode of described tension shaft core 102 spiral winding by wire, two neighboring institute
State winding direction wiry in torsion layer 101 contrary, and two neighboring described torsion layer 101 contacts；
The two ends of described axis body 10 connect external impetus system and external impetus switching mechanism respectively, can be in outside dynamical system
Rotate motion in described flexible pipe 20 under the rotary power that system provides, and drive external impetus mechanism to rotate motion.
In the above embodiment of the present invention, it is wound around out at least two in the way of spiral winding in tension shaft core using wire
, to form axis body, in two neighboring torsion layer, wire winding direction is contrary for individual torsion layer, and two neighboring torsion layer contacts,
Axis body is made to rotate motion under the power that outside dynamical system provides in flexible pipe to drive power conversion mechanism to occur
During rotary motion, in the wire that two neighboring torsion layer inside spin is wound around, one layer tends to unscrewing, and another layer tends to tightening, and makes
The two neighboring torsion layer that must contact with each other can cancel each other out respective a part of deflection, and then reduction flexible axle deforms
Degree.
In one embodiment of the invention, flexible axle drives power conversion mechanism to revolve according to the rotary power that dynamical system provides
When transhipment is dynamic, its major function is embodied in can be with cut-through object so that dynamical system and power conversion mechanism rotate
The axis of motion can be no longer on straight line, and therefore, tension axle center should be able to occur a certain degree of bending, for example,
Tension axle center can be one and be easy to bend, and possesses more high-tensile wire.
In one embodiment of the invention, the quantity of torsion layer can according to practical business scene central axis need the moment of torsion of transmission Lai
Rationally arrange, torsion layer number is more and all the more tight during wire spiral winding, and the transferable moment of torsion of flexible axle is bigger；Meanwhile,
Winding direction wiry in axis body outermost torsion layer is it should the rotation being provided in outside dynamical system with axis body is moved
Corresponding direction of rotation during rotary motion occurs under power, and on the contrary, that is, axis body outermost torsion layer should rotate fortune in axis body
When tending to when dynamic tightening, more it is beneficial to reduce the degree that flexible axle deforms.
Further, in order that flexible axle rotates corresponding rotary speed and power transmission shaft in power conversion mechanism during motion
Rotary speed, the rotary speed of driving shaft is consistent in dynamical system, as shown in Fig. 2 a preferred embodiment of the invention
