Abstract

The motor shaft (1) has splines holding a flange (13) supporting the drive element of a centrifugal clutch (15, 11a). This clutch consists of shoes (15) moving outward to engage a drum (11a) forming part of a spider (11) carrying shafts (4) for the planet gears (3). The output shaft (5b) is an extension of the spider for the planet gears. There is a bearing (8) for the end of the motor shaft inside the hollow end of the output shaft, and there is a further bearing (10) for the spider inside the ring gear (7). The ring gear is supported by a roller bearing with a freewheel mechanism (9).The teeth of the planet gears are constantly in mesh with the teeth on the ring gear and teeth (2) on the end of the input shaft.

Description

On sait que le fonctionnement des réducteurs epicycloldaux nécessite un blocage de la couronne extérieure coopérant avec les satellites pour que l'arbre secondaire soit entrain dans le même sens que l'arbre primaire, mais a une vitesse moindre, c'est-a-dire que l'arbre secondaire tourne à une vitesse angulaire

Figure img00010001

01 étant la vitesse angulaire de l'arbre primaire, #2 étant la vitesse angulaire de l'arbre secondaire et K le rapport de réduction.We know that the operation of epicyclic reducers requires a blocking of the outer ring cooperating with the satellites so that the secondary shaft is driven in the same direction as the primary shaft, but at a lower speed, that is to say that the secondary shaft rotates at an angular speed
Figure img00010001

01 being the angular speed of the primary shaft, # 2 being the angular speed of the secondary shaft and K the reduction ratio.

Si l'arbre secondaire devient moteur, c'est=a-dire ni sa vitesse augmente, le réducteur fonctionne en multiplicateur, de telle sorte que la vitesse de l'arbre primaire augmente aussi. If the secondary shaft becomes motor, ie neither its speed increases, the reduction gear operates as a multiplier, so that the speed of the primary shaft also increases.

Dans des applications particulières, et plus spEcialement lorsqu'un réducteur epicyclordal est associé au moteur d'un démarreur électrique pour moteur à combustion interne, il est souhaitable que les dents du pignon du lanceur accompagnent constamment celles de la grande couronne du moteur thermique dans les phases d'accélération de celui-ci, apyres passage des points morts hauts notamment. Cet accompagnement constant évite les chocs donc les bruits et l'usure prématurée des organes en prise. les perfectionnements qui font l'objet de la présente invention visent à permettre la réalisation d'un système permettant d'obtenir le résultat exposé ci-dessus. In particular applications, and more especially when an epicyclic reduction gear is associated with the motor of an electric starter for an internal combustion engine, it is desirable that the teeth of the pinion of the starter constantly accompany those of the large crown of the heat engine in the acceleration phases of the latter, especially after passing through top dead centers. This constant support avoids shocks, therefore noises and premature wear of the engaged parts. the improvements which are the subject of the present invention aim to allow the production of a system making it possible to obtain the result set out above.

A cet effet, le plateau porte-satellites du réducteur SpicycloIdal suivant l'invention est associé à un tambour avec lequel vient coopérer au moins une mâchoire ou masselotte portée par l'arbre primaire, un système d'entratnement unidirectionnel étant associe h la couronne dudit réducteur de manière que celle-ci soit bloquée en rotation lorsque l'arbre primaire entrain l'arbre secondaire et qu'elle soit libérée lorsque celui-ci devient menant. To this end, the planet carrier plate of the SpicycloIdal reducer according to the invention is associated with a drum with which comes to cooperate at least one jaw or flyweight carried by the primary shaft, a unidirectional drive system being associated with the crown of said reducer so that it is blocked in rotation when the primary shaft drives the secondary shaft and that it is released when the latter becomes leading.

le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle pressente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une coupe longitudinale d'un réducteur Spicycloidal établi conformément à l'invention.the appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it senses and the advantages which it is likely to provide
Fig. 1 is a longitudinal section of a Spicycloidal reducer established according to the invention.

Fig. 2 en est une coupe transversale suivant II-II (fig. 1). Fig. 2 is a cross section along II-II (fig. 1).

On y a fait figurer en I-I le plan de coupe de fig. 1.We have included in I-I the section plane of fig. 1.

Fig. 3 en est une autre coupe transversale brisée suivant
III-III (fig. 1).Fig. 3 is another broken cross section following
III-III (fig. 1).

On a illustré en fig. 1 un réducteur épicycloidal comprenant essentiellement un arbre moteur 1 dont l'extremite est taillée pour constituer un engrenage 2 en prise avec des satellites 3 portés par des axes 4 solidaires d'un plateau porte-satellites 5. les satellites 3 engrènent en outre avec la denture intérieure 6 d'un organe tubulaire à deux diamètres référencé 7. On observe que l'arbre 1 se prolonge par un embout la engagé dans un coussinet 8 disposé dans un alésage central Sa du plateau porte-satellites 5 qui se prolonge par une queue 5b portant par exemple un pignon d'entratnement d'un mécanisme quelconque. Dans le cas particulier de l'utilisation du réducteur suivant l'invention dans un démarreur électrique, la queue 5b porte le pignon du lanceur. Illustrated in fig. 1 a planetary reduction gear essentially comprising a motor shaft 1 the end of which is cut to form a gear 2 engaged with satellites 3 carried by axes 4 secured to a planet carrier plate 5. the satellites 3 further mesh with the internal toothing 6 of a tubular member with two diameters referenced 7. It can be seen that the shaft 1 is extended by a nozzle engaged in a bearing 8 disposed in a central bore Sa of the planet carrier plate 5 which is extended by a tail 5b carrying for example a drive pinion of any mechanism. In the particular case of using the reduction gear according to the invention in an electric starter, the tail 5b carries the pinion of the starter.

On observe que l'organe tubulaire 7 comporte deux cylindres co-axiaux dont l'un 7a constitue support de la couronne dentée 6, tandis que l'autre rèférencè 7b porte sur sa périphérie un roulement 9 pourvu d'un système d'entraînement unidirectionnel. Ce roulement est monté entre ledit cylindre 7b et le carter du réducteur. Lorsque l'arbre 1 tourne dans un sens, il entraine les satellites 3 qui ont tendance à faire tourner la couronne 6 dans un sens tel que le système d'entratnement unidirectionnel du roulement 9 se bloque.Dans ces conditions, les satellites roulent par rapport à la denture de la couronne 6, de telle sorte que le porte-satellites 5 est entrasse en rotation ainsi que le pignon qui est calé angulairement sur sa queue 5b. On observe la présence d'un coussinet 10 assujetti à l'alésage du cylindre 7b de l'organe 7 et par rapport auquel l'extérieur du porte-satellites 5 tourne. It is observed that the tubular member 7 comprises two co-axial cylinders, one of which 7a constitutes the support of the toothed ring 6, while the other referenced 7b carries on its periphery a bearing 9 provided with a unidirectional drive system . This bearing is mounted between said cylinder 7b and the housing of the reducer. When the shaft 1 rotates in one direction, it drives the satellites 3 which tend to rotate the crown 6 in a direction such that the unidirectional drive system of the bearing 9 is blocked. Under these conditions, the satellites roll relative to the teeth of the crown 6, so that the planet carrier 5 is rotated as well as the pinion which is wedged angularly on its tail 5b. We observe the presence of a pad 10 subject to the bore of the cylinder 7b of the member 7 and relative to which the outside of the planet carrier 5 rotates.

Conformément à l'invention, un contre-plateau 11 est associé au plateau 5 au moyen de goupilles 12. Ce contre-plateau qui retient les satellites se prolonge par un tambour lla. L'arbre 1 est pourvu d'une zone cannelée lb sur laquelle est calé angulairement un flasque 13 dont la face tournée vers les satellites 3 porte deux axes fixes 14 autour de chacun desquels est montée à pivotement une mâchoire ou masselotte 15 qui est en appui clastique grâce à un ressort 16 contre un doigt 17. According to the invention, a counter-plate 11 is associated with the plate 5 by means of pins 12. This counter-plate which retains the satellites is extended by a drum 11a. The shaft 1 is provided with a grooved zone 1b on which is angularly wedged a flange 13 whose face facing the satellites 3 carries two fixed axes 14 around each of which is pivotally mounted a jaw or flyweight 15 which is in abutment clastic thanks to a spring 16 against a finger 17.

Bien entendu, la force d'appui de chaque mâchoire sur son pion 17 est regelée au repos par la pré-tension du ressort 16. On observe que l'une des extrémité de chaque ressort 16 est accrochée au niveau de l'extrémitE libre d'une mâchoire, tandis que son extrémité opposee est attachée à la partie de la mâchoire opposée située près de son axe d'articulation 14. Of course, the bearing force of each jaw on its pin 17 is frozen at rest by the pre-tension of the spring 16. It is observed that one of the ends of each spring 16 is hooked at the free end d a jaw, while its opposite end is attached to the part of the opposite jaw located near its axis of articulation 14.

Le fonctionnement découle des explications qui précèdent. Operation follows from the foregoing explanations.

Le réducteur faisant l'objet de la présente invention peut etre utilisé pour toute application mécanique, mais il est plus particuliere- ment étudie pour entre associé à un démarreur électrique pour moteur a combustion interne. Dans cette application particuliere, lorsque l'arbre 1 est entraSnd par le moteur électrique, le pignon 2 entratne les satellites 3 qui ont tendance à faire tourner la couronne 6 dans un sens tel quelle est bloque par le système d'entratnement unidirectionnel du roulement 9. Dans ces conditions, c'est le porte-satellites 5 qui tourne en entrainant le pignon non représente calé angulairement sur sa queue 5b.Ce pignon vient de la manière usuelle coopérer avec la grande couronne non représentée du moteur à combustion interne, de telle sorte que celui-ci est entrasse en rotation. The reducer which is the subject of the present invention can be used for any mechanical application, but it is more particularly studied for between associated with an electric starter for internal combustion engine. In this particular application, when the shaft 1 is driven by the electric motor, the pinion 2 drives the satellites 3 which tend to rotate the crown 6 in a direction as it is blocked by the unidirectional drive system of the bearing 9 Under these conditions, it is the planet carrier 5 which rotates by driving the pinion not shown angularly wedged on its tail 5b. This pinion comes in the usual way to cooperate with the large crown not shown of the internal combustion engine, such so that it is rotated.

L'arbre 1 du démarreur électrique entrains les satellites 3 (fig. 3), le plateau 5 qui les porte et-qui est lié au pignon de démarrage étant immobile lors de la mise en rotation dudit arbre 1 oppose un couple rEslstant qui tend a faire tourner la couronne extérieure 6 à l'encontre de la roue libre du roulement 9, qui se bloque. The shaft 1 of the electric starter drives the satellites 3 (fig. 3), the plate 5 which carries them and which is linked to the starting pinion being stationary during the rotation of said shaft 1 opposes a constant torque which tends to rotate the outer ring 6 against the free wheel of the bearing 9, which is blocked.

Le plateau 5, donc le pignon de démarrage, tourne alors dans le même sens que l'arbre 1. The plate 5, therefore the starting pinion, then rotates in the same direction as the shaft 1.

lors de l'accélération du moteur thermique qui est lié au plateau 5 des satellites 3 par le pignon de démarrage, l'arbre 1 oppose son tour un couple résistant dû B l'inertie de l'induit qui tend a faire tourner la couronne 6 dans le même sens que le plateau 5. La roue libre se débloque, empêchant ainsi les satellites 3 de provoquer l'accélération de l'arbre 1. Le moteur électrique portant ce dernier accEldre normalement et agit sur les masselottea, le réducteur est court-circuitE, le moteur électrique est 116 directement au pignon de démarrage dès que la vitesse de centrifugation des masselottes est atteinte. during the acceleration of the heat engine which is linked to the plate 5 of the satellites 3 by the starting pinion, the shaft 1 in turn opposes a resistant torque due to the inertia of the armature which tends to rotate the crown 6 in the same direction as the plate 5. The freewheel is released, thus preventing the satellites 3 from causing the acceleration of the shaft 1. The electric motor carrying the latter accEldre normally and acts on the weights, the reduction gear is short- circuitE, the electric motor is 116 directly at the starting pinion as soon as the centrifuge speed of the weights is reached.

On peut remarquer que la roue libre du roulement 9 permet la suppression éventuelle de la roue libre habituellement prevue sur le lanceur interne, car le demarrage du moteur a combustion, quand le pignon de démarrage est en prise avec la grande couronne, n'entraîne par l'induit du moteur electrique du démarreur. On observe que l'extérieur des mâchoires est pourvu d'un revêtement anti-friction 18. Dans ces conditions, l'arbre 1 devient solidaire du plateau porte-satellites 5, de sorte que la vitesse de celui-ci, qui est communiquée par le moteur athermique, se transmet intégralement à l'arbre 1. On revient ainsi une configuration classique d'un démarreur électrique ne comportant pas de réducteur épicycloIdal, ce qui permet au pignon du lanceur calé sur la queue 5b du porte-satellites d'accompagner constamment la grande couronne du moteur thermique dans les phases d'accélération de celui-ci. It can be noted that the free wheel of the bearing 9 allows the possible elimination of the free wheel usually provided on the internal launcher, since the starting of the combustion engine, when the starting pinion is engaged with the large crown, does not cause the armature of the electric starter motor. It is observed that the outside of the jaws is provided with an anti-friction coating 18. Under these conditions, the shaft 1 becomes integral with the planet carrier plate 5, so that the speed of the latter, which is communicated by the athermic motor is transmitted entirely to the shaft 1. This returns to a conventional configuration of an electric starter not comprising a planetary gearbox, which allows the pinion of the launcher wedged on the tail 5b of the planet carrier to accompany constantly the large crown of the heat engine in the acceleration phases thereof.

I1 doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
