Abstract

Elastic pins 3 are engaged in radial perforations 1c in a fixed sleeve 1 so that one of their ends cooperates with corresponding depressions 2a made in the periphery of the crown wheel 2 whereas their opposite end, which penetrates inside the sleeve, is brought back inside the said perforations through an outer hoop 4 so as to compress the pins against the crown wheel 2.

Description

On sait que dans les démarreurs électriques pour moteurs à combustion interne, on a de plus en plus tendance, en vue de diminuer l'importance du moteur électrique, d'utiliser à la sortie de celui-ci un réducteur, épicycloSdal propre à entralner l'arbre du lanceur au moyen de ses satellites. We know that in electric starters for internal combustion engines, there is an increasing tendency, in order to reduce the importance of the electric motor, to use at the output thereof a reducer, epicycloSdal suitable for driving the launcher tree using its satellites.

Dans ce genre de réducteur,ii est difficile d'assurer un centrage parfait de toutes les pièces en mouvement, de telle sorte que la couronne extérieure à denture interne est avantageusement associée au manchon fixe entourant le réducteur au moyen d'une suspension élastique. Une telle suspension a été décrite dans le document EP -A-0098992. Mais cette suspension occupe un encombrement très important, du fait que les blocs de suspension sont prévus dans une collerette du nez du démarreur se trouvant assez éloignée par rapport à la carcasse du moteur électrique. En outre, les blocs sont simplement retenus à force dans ces ouvertures de la collerette, de telle sorte qu'ils ne sont pas appliques avec une pression satisfaisante contre la couronne extérieure du demarreur en vue de la maintenir. In this type of reducer, it is difficult to ensure perfect centering of all the moving parts, so that the outer ring with internal teeth is advantageously associated with the fixed sleeve surrounding the reducer by means of an elastic suspension. Such a suspension has been described in document EP -A-0098992. However, this suspension occupies a very large space, because the suspension blocks are provided in a flange of the nose of the starter being quite distant from the carcass of the electric motor. In addition, the blocks are simply retained by force in these openings of the collar, so that they are not applied with satisfactory pressure against the outer ring of the starter in order to maintain it.

Les perfectionnements qui font l'objet de la présente invention visent A remédier aux inconvénients du système décrit ci-dessus et à réaliser une excellente suspension élastique de la couronne du réducteur qui présente un faible encombrement général. The improvements which are the subject of the present invention aim to remedy the drawbacks of the system described above and to produce an excellent elastic suspension of the crown of the reducer which has a small overall size.

A cet effet, le manchon fixe entourant le réducteur, et qui dans le cas particulier de l'application à un démarreur électrique pour moteur thermique est constitué par la carcasse de son moteur électrique, comporte des perforations radiales dans lesquelles sont engagés des plots élastiques dont l'une des extrémités coopère avec des dépressions ménagées dans la périphérie de la couronne, tandis que leur extrémité opposée, qur dépasse a l'extérieur du manchon, est ramenée A l'intérieur desdites perforations par une frette extérieure, de manière à comprimer les plots contre la couronne. To this end, the fixed sleeve surrounding the reducer, and which in the particular case of application to an electric starter for a heat engine is constituted by the carcass of its electric motor, has radial perforations in which elastic studs are engaged, of which one of the ends cooperates with depressions formed in the periphery of the crown, while their opposite end, which protrudes outside the sleeve, is brought inside said perforations by an external hoop, so as to compress the studs against the crown.

Le dessin annexé, donné à titre d'exemple permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue éclatée en perspective des différents éléments d'un système de suspension suivant l'invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is likely to provide.
Fig. 1 is an exploded perspective view of the various elements of a suspension system according to the invention.

Fig. 2 est une vue en perspective montrant une variante de réalisation de dépression ménagée dans la couronne extérieure du réducteur. Fig. 2 is a perspective view showing an alternative embodiment of the depression formed in the outer ring of the reduction gear.

Fig. 3 est une coupe transversale partielle d'un réducteur monté par rapport à une plaque transversale fixe.  Fig. 3 is a partial cross section of a reduction gear mounted relative to a fixed transverse plate.

Fig. 4 en est une coupe suivant IV-IV (fig. 3). Fig. 4 is a section on IV-IV (fig. 3).

En fig. 1, on a référencé 1 un manchon cylindrique qui, dans une application particulièrement intéresssante de l'invention relative à un démarreur électrique pour moteur à combustion interne, constitue une partie de la carcasse du moteur électrique dudit démarreur. Comme à l'accoutumée, le manchon comporte une collerette extrême la dans laquelle sont prévus des trous lb destinés à sa fixation au nez du démarreur. De manière usuelle, la carcasse du démarreur est fermée au moins partiellement à son extrémité oppose à la collerette la, de telle sorte que toutes les pièces du moteur électrique sont montées à partir de l'ouverture centrale de celle-ci. On observe que le manchon 1 est pourvu de perforations radiales lc prévues au nombre de trois dans l'exemple illustré. La couronne extérieure à denture interne du réducteur épicyclordal a été référencée 2.Sa périphérie est pourvue de dépressions réalises comme illustré en fig. 1 sous la forme de trous borgnes 2a dont le diamètre est en gros égal à celui des perforations lc. In fig. 1, reference has been made to 1 a cylindrical sleeve which, in a particularly interesting application of the invention relating to an electric starter for an internal combustion engine, constitutes part of the carcass of the electric motor of said starter. As usual, the sleeve has an extreme flange la in which are provided holes lb intended for its attachment to the nose of the starter. Usually, the starter casing is closed at least partially at its end opposite the flange la, so that all the parts of the electric motor are mounted from the central opening thereof. It is observed that the sleeve 1 is provided with radial perforations lc provided three in number in the example illustrated. The outer ring with internal toothing of the epicyclic reduction gear has been referenced 2. Its periphery is provided with depressions produced as illustrated in FIG. 1 in the form of blind holes 2a whose diameter is roughly equal to that of the perforations lc.

Une fois que le moteur électrique a été placé à l'intérieur de la carcasse, on amène la couronne 2 au niveau des perforations lc de manière que celles-ci correspondent aux trous borgnes 2a de iadite couronne. On engage ensuite des plots 3 réalisés en caoutchouc de dureté appropriée et présentant une forme cylindrique, de manière qu'ils traversent les perforations lc et qu'une de leurs extrémités vienne coopérer avec les trous borgnes 2a contre le fond desquels ils butent. Once the electric motor has been placed inside the carcass, the crown 2 is brought to the level of the perforations lc so that these correspond to the blind holes 2a of said crown. Then engaged pads 3 made of rubber of suitable hardness and having a cylindrical shape, so that they pass through the perforations lc and that one of their ends comes to cooperate with the blind holes 2a against the bottom of which they abut.

La longueur des plots 3 est telle qu'ils dépassent légèrement à l'extérieur des perforations lc
L'opération suivante consiste à engager une frette 4 autour du manchon 1 de manière que sa face intérieure vienne au contact des extrémités extérieures des plots 3. Puis, par une opération mécanique, par exemple par rétreint ou par magnéto-formage, on applique la frette contre I'extérieur du manchon 1 de manière à comprimer les plots de telle sorte que leurs extrémités extérieures reviennent au niveau du pourtour du manchon 1.
The length of the studs 3 is such that they slightly protrude outside the perforations lc
The following operation consists in engaging a hoop 4 around the sleeve 1 so that its inner face comes into contact with the outer ends of the pads 3. Then, by a mechanical operation, for example by shrinking or by magneto-forming, the hoop against the outside of the sleeve 1 so as to compress the studs so that their outer ends return to the periphery of the sleeve 1.

On comprend aisément que les plots élastiques assurent le maintien latéral de la couronne 2 sans qu'il soit besoin d'autres butées latérales, ainsi que le centrage élastique de cette couronne en vue de permettre un ajustement des dentures des éléments du réducteur si une excentration éventuelle survient. It is easily understood that the elastic studs ensure the lateral retention of the crown 2 without the need for other lateral stops, as well as the elastic centering of this crown in order to allow adjustment of the teeth of the elements of the reducer if an eccentricity eventual occurs.

L'élasticité des plots peut être modulée en fonction des matières utilisées et de la forme de ceux-ci. Bien entendu, les plots peuvent être armés si ltélasticité doit etre réduite. The elasticity of the studs can be varied depending on the materials used and the shape thereof. Of course, the studs can be reinforced if the elasticity has to be reduced.

Comme illustré en fig. 2, les dépressions de la couronne 2 pourraient être réalisées non plus au moyen de trous borgnes, mais grâce à des rainures longitudinales borgnes 2b, 2c, issues alternativement des deux faces latérales de la couronne afin que la retenue axiale de celle-ci soit assurée par butée des plots 3 contre les extrémités borgnes des rainures. As illustrated in fig. 2, the depressions in the crown 2 could no longer be produced by means of blind holes, but thanks to blind longitudinal grooves 2b, 2c, coming alternately from the two lateral faces of the crown so that its axial retention is ensured by abutment of the studs 3 against the blind ends of the grooves.

On a ainsi réalisé un système de suspension de la couronne extérieure A denture interne d'un réducteur épicyloldai par rapport à un manchon dont le montage des éléments peut s'effectuer par I'extérieur apres que la couronne 2 ait été placée à l'intérieur du manchon 1. On aperçoit en fig. 3 le montage définitif après rétreint de la frette 4. On observe un jeu relativement important référencé J entre le pourtour de la couronne et la face interne du manchon 1. A suspension system for the outer ring has thus been produced With internal toothing of an epicyloid gearbox relative to a sleeve, the elements of which can be mounted from the outside after the ring 2 has been placed inside. of the sleeve 1. We see in fig. 3 final assembly after shrinking of the hoop 4. There is a relatively large clearance referenced J between the periphery of the crown and the internal face of the sleeve 1.

En fig. 4, on a représenté en traits discontinus le pignon central 5 du réducteur ainsi que ses satellites 6 dont les axes 7 sont associes à une plaque non représentée destinée a l'entranement de l'arbre de sortie également non représenté et qui est guidé dans un palier 8 (fig. 3) ménagé au centre d'une plaque 9 A laquelle la collerette la du manchon 1 est assemblée par boulonnage, rivetage, etc;...  In fig. 4, there is shown in broken lines the central pinion 5 of the reducer as well as its satellites 6 whose axes 7 are associated with a plate not shown intended for the drive of the output shaft also not shown and which is guided in a bearing 8 (fig. 3) formed in the center of a plate 9 to which the collar 1a of the sleeve 1 is assembled by bolting, riveting, etc; ...

I1 doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'A titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les details d'exécution décrits par tous autres équivalents.  It should moreover be understood that the foregoing 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 details of execution described by all other equivalents.
