MONTAGE D'UN DIFFERENTIEL COMME MODIFICATEUR-INVERSEUR DE VITESSE.
PRINCIPE :
Dans un système différentiel, la relation entre : la vitesse de l'arbre-moteur W1 la vitesse de l'arbre récepteur W2 la vitesse de la cage des satellites W3 EST sous cette forme :
2 W3 = W1 + W2 ou W2 = 2W - W1 2 @3 W1
Si donc, on se propose de faire varier la vitesse W2 depuis (-W1) à (+W1) en passant par zéro, indépendamment de W1, il faudra donc agir sur W3,et, suivant la valeur de celle-ci, la vitesse W2 sera négative, nul ou positive.
REALISATION :(voir schéma ci-annexé).
Un système différentiel,à engrenages et satellites M. dont la cage des satellites y est mise en relation avec l'arbre moteur W1 par l'in- termédiaire d'un jeu d'engrenages AB (rapport A/B = I), puis d'un variateur de vitesse quelconque V et ensuite d'un second jeu d'engrenages DC (rapport C/D = 1/2) dont l'un (C) est calé sur l'arbre moteur WI.
Le variateur de vitesse V permet de modifier le rapport des vites- ses entre son arbre primaire et son arbre secondaire de 1/3 à 2 pratiquement et ce, d'une manière progressive.
D'autre part, a) l'arbre secondaire tourne à la même vitesse que W3 (puisque A/B = I).
<Desc/Clms Page number 2>
b) l'arbre primaire tourne à la 1/2 vitesse de W1 par suite du jeu d'engre- nages CD (CD = 1/2).
D'où, la vitesse W3 est liée à la vitesse W1 et peut varier dans les porportions du variateur c.à.d. entre Wl/2.Ï/3 = WI/6 et WI.2/2= WI ce qui peut s'écrire :
EMI2.1
WI/6 .E; Vl3 WI Dès lors, en reprenant la formule de base :

W2" 2W3 - l on aura : bzz pour W3 = WI6 W2 = 2WI/6 - WI = ( -2/3 WI) b) pour W3 = ,WI/2, W2 = 2WI/2 - WI = 0. c ) pour W3 = WI Wz = 2WI - WI = ( + Wr) Conclusion :
Un différentiel, monté suivant le schéma ci-joint, permettra donc.de faire varier la vitesse d'un récepteur sans toucher à celle du mo-

teur, depuis WT/w2 = lui (limité pratiquement à -Z/3 ) à WI/W2 = +1 en pas- sant par toutes les valeurs intermédiaires (vitesse nul comprise) et ce, d'une façon tout à fait progressive en agissant uniquement sur le variateur de vitesse V.

MOUNTING OF A DIFFERENTIAL AS A SPEED MODIFIER-INVERTER.
PRINCIPLE:
In a differential system, the relationship between: the speed of the motor shaft W1 the speed of the receiver shaft W2 the speed of the cage of the satellites W3 IS in this form:
2 W3 = W1 + W2 or W2 = 2W - W1 2 @ 3 W1
If therefore, we propose to vary the speed W2 from (-W1) to (+ W1) passing through zero, independently of W1, it will therefore be necessary to act on W3, and, depending on the value of this one, the speed W2 will be negative, zero or positive.
REALIZATION: (see attached diagram).
A differential system, with gears and planetary planes M., the planet gear cage of which is connected there to the motor shaft W1 by means of a set of gears AB (ratio A / B = I), then a variable speed drive V and then a second set of DC gears (C / D ratio = 1/2), one of which (C) is wedged on the motor shaft WI.
The speed variator V makes it possible to modify the speed ratio between its primary shaft and its secondary shaft from 1/3 to 2 practically and this, in a progressive manner.
On the other hand, a) the secondary shaft rotates at the same speed as W3 (since A / B = I).
<Desc / Clms Page number 2>
b) the primary shaft rotates at 1/2 speed of W1 as a result of the CD gear set (CD = 1/2).
Hence, the speed W3 is linked to the speed W1 and can vary within the portions of the variator i.e. between Wl / 2.Ï / 3 = WI / 6 and WI.2 / 2 = WI which can be written:
EMI2.1
WI / 6 .E; Vl3 WI From then on, using the basic formula:
EMI2.2
W2 "2W3 - l we will have: bzz for W3 = WI6 W2 = 2WI / 6 - WI = (-2/3 WI) b) for W3 =, WI / 2, W2 = 2WI / 2 - WI = 0. c) for W3 = WI Wz = 2WI - WI = (+ Wr) Conclusion:
A differential, mounted according to the attached diagram, will therefore make it possible to vary the speed of a receiver without affecting that of the mo-
EMI2.3
tor, from WT / w2 = him (limited practically to -Z / 3) to WI / W2 = +1 going through all the intermediate values (zero speed included) and this, in a completely progressive way in acting only on the speed controller V.
