The present invention uses the single-wheel of rotation to rub with the hands and turns round, and its operation principle is as follows:
Rely on the frictional force between rubbing wheel V-groove inwall and optical fiber, rubbed with the hands by tilt rotation V-shaped groove and turn round wheel, at optical fiber
Horizontal rubbing speed is produced so that optical fiber can carry out lateral rotation the most as requested during high-speed wire-drawing.
As figure turns round wheel angle of inclination to during θ rubbing with the hands, rub with the hands and turn round wheel in the vertical direction and exist and maintain and at that time
Component velocity v that drawing speed is equal1.The most then there are cross stream velocity component v2.It is specifically shown in Fig. 9:
As seen from the figure, lateral velocity v that torsion is dynamic is rubbed with the hands2Size and drawing speed v1Relation be:
V2=V1·tanθ
Rotational angle θ is less when, tan θ can be approximately equal to sin θ.So, its relation can be approximated to be:
V2=V1·Sinθ
In drawing process, turning round wheel rotation along with rubbing with the hands, the torsional strength that its lateral velocity is brought is approximately a sine
Relation.As long as turning round one metastable forward of wheel and the angular velocity of recycled back so giving when drawing speed is stablized to rub with the hands,
Rub with the hands and turn round the rubbing effect that just can apply there is sinuso sine protractor on optical fiber, thus reach to rub the work purpose turned round with the hands.By this specially
Device is turned round in the stranding that profit describes, and selects suitable technical recipe: amplitude of fluctuation (5 °～30 °) and hunting period (0.3s～1s),
Good take: amplitude of fluctuation is 10 °, cycle 0.5s.Under conditions of meeting phase matched, effect is turned round in available optimal stranding.
Use the single-wheel rotated to rub torsion with the hands to have the advantage that
One. adjust requirement easily
The single-wheel of rotation is rubbed with the hands and is turned round owing to relying on stranding torsion angle that optical fiber is carried out rubbing, and it only needs to rub with the hands to turn round according to uniformly
It is gradual that rotational angular velocity can be achieved with rubbing the sine turned round in rubbing effect with the hands.Turn round in whole system additionally, rotation single-wheel is rubbed with the hands
The tensile requirements of spring is relatively low, as long as can ensure that enough elastic force makes to rub with the hands to turn round can arrive predetermined position.Protecting
Barrier is rubbed with the hands in the case of turning round wheel and two location wheel collimations, can adjust to rub with the hands and turn round the pressure fibre distance of wheel to adjust optical fiber in drawing process
The frictional force that surface is born, thus finely tune and rub the rubbing effect turned round optical fiber with the hands.Integrated regulation method is relatively simple, and its effect is the most relatively
For substantially.
Two. less optical fiber damage
Rotation single-wheel is rubbed with the hands and is turned round on the one hand owing to only relying on the V-groove drive fiber rotation of single-wheel, the extruding to optical fiber
Dynamics is less and conveniently adjusts, so being difficult to compared with rubbing torsion with the hands with two-wheel optical fiber surface is produced damage.On the other hand, owing to rotating
Rub torsion rubbing with the hands and rely primarily on the central interface point of wheel V-groove and optical fiber, compared with translating type single-wheel stranding torsion, when rubbing to light
Fine squish area and lateral pressure are the least, so being difficult to equally optical fiber surface is produced damage.
Three. stable rubbing effect
The rubbing mechanism turned round due to rotation single-wheel stranding is relatively simple, so having only to periodically enter the bearing rubbing torsion train with the hands
Row maintenance collimation carry out inspection just can keep preferable rubbing effect.Rub with the hands relative to two-wheel and turn round, owing to need not two-wheel
Compress, rub torsion wheel with the hands and be not likely to produce damage during normal use, significantly increase the maintaining time rubbing torsion with the hands and spare part
The replacement time.Rubbing with the hands relative to the single-wheel of translational type and turn round, rotation single-wheel is rubbed with the hands and is turned round owing to rubbing effect region is only groove central authorities, therefore
And V-groove gradient requires relatively low, after train is changed in maintenance, remain to the stranding before continuing to use replacing turn round technical recipe.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this.All according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
