Abstract

Planetary reduction gear with eccentrics with two double eccentrics offset by 180 DEG for which the toothed drive wheel of a double eccentric is fixed against the partial shoulder formed by one of the eccentrics and a stop plate is fixed by pressing it, with the aid of screws, against the partial shoulder formed by the other eccentric, the distance between the bearing faces of the toothed wheel and of the stop plate being such that the two gears to which the double eccentrics give a circular movement move over the eccentrics thereby having sufficient clearance which clearance is, however, limited by the bearing faces of the toothed wheel and of the stop plate.

Description

Le brevet dépose le 02-08-82 sous le NO 8213657 concerne un réducteur plar. taire excentriques dont les excentriques tourillonnent sur des axes fixes qui sont encastrés dans le carter du réducteur, ces excentriques étant entrainés en rotation chacun par au moins une roue dentée solidaire de chacun des excentriques, les roues dentées des différents excentriques étant entraînées par le même pignon qui est coaxial avec l'arbre de sortie du réducteur. Dans le brevet principal les roues dentées qui entraînent les excentriques sont reliés aux excentriques par des clavettes, le but de la présente addition est une simplification du montage des excentriques dans le cas d'excentriques doubles décalés de l80. The patent filed 02-08-82 under NO 8213657 relates to a plar reducer. silent eccentrics whose eccentrics rotate on fixed axes which are embedded in the gearbox housing, these eccentrics being driven in rotation each by at least one toothed wheel secured to each of the eccentrics, the toothed wheels of the different eccentrics being driven by the same pinion which is coaxial with the gearbox output shaft. In the main patent the toothed wheels which drive the eccentrics are connected to the eccentrics by keys, the purpose of the present addition is a simplification of the mounting of the eccentrics in the case of double eccentrics offset by 180.

A cet éffet, d'une part la roue dentée est fixée a l'excentrique double en la plaquant & l'aide de vis contre l'épaulement partiel formé par l'un des excentr iques, un pion servant a l'entraînement de l'excentrique par la roue dentée et vice versa, d'autre part une plaque d'arr8t est fixée en la plaquant d l'aide de vis contre l'épaulement partiel formé par l'autre excentrique, la distance entre les faces d'appui de la roue dentée et de la plaque d'arrêt étant telle que les deux engrenages auxquels les excentriques donnent un mouvement circulaire se déplacent sur les excentriques en ayant un jeu axial l'un par rapport 9 l'autre suffisant mais limité par les faces d'appui de la roue dentée et de la plaque d'arrEt. Les Fig. 1 & 2 ci annexées représentent & titre indicatif et non limitatif un montage des excentriques selon la présente addition.La Fig. 1 est une coupe passant par l'axe d'un excentrique double 17, la Fig. 2 est une coupe par le plan Il II de la Fig. 1 montrant la fixation de la roue dentée 23 sur l'excentrique 19. 50 est le pion d'entraînement de l'excentrique 17 par la roue dentée 23; 51,52,53 & 54 sont les vis de fixation de la roue dentée 23 sur l'épaulement partiel de l'excentrique 19.La plaque d'arrêt 55 est fixée contre l'épaulement partiel de l'excentrique 18 a l'aide des vis-56,57,58 & 59. la distance entre les faces d'appui de la roue dentée 23 et de la plaque d'arrêt 55 est telle que les engrenages 37 & 43 auxquels les excentriques 18 & 19 donnent un mouvement circulaire se déplacent l'un par rapport d l'autre en ayant un jeu axial suffisant mais limité par les faces d'appui de la roue dentée 23 et de la plaque d'arrêt 5,.To this end, on the one hand, the toothed wheel is fixed to the double eccentric by pressing it with the aid of screws against the partial shoulder formed by one of the eccentrics, a pin serving for driving the eccentric by the toothed wheel and vice versa, on the other hand a stop plate is fixed by pressing it with screws against the partial shoulder formed by the other eccentric, the distance between the bearing faces of the toothed wheel and the stop plate being such that the two gears to which the eccentrics give a circular movement move on the eccentrics with an axial play relative to each other sufficient but limited by the faces d support of the toothed wheel and the stop plate. Figs. 1 & 2 attached hereto represent an indicative and nonlimiting assembly of the eccentrics according to this addition. 1 is a section passing through the axis of a double eccentric 17, FIG. 2 is a section through the plane II II of FIG. 1 showing the fixing of the toothed wheel 23 on the eccentric 19. 50 is the drive pin of the eccentric 17 by the toothed wheel 23; 51,52,53 & 54 are the fixing screws of the toothed wheel 23 on the partial shoulder of the eccentric 19. The stop plate 55 is fixed against the partial shoulder of the eccentric 18 using screws 56,57,58 & 59. the distance between the bearing faces of the toothed wheel 23 and the stop plate 55 is such that the gears 37 & 43 to which the eccentrics 18 & 19 give a circular movement move relative to each other with sufficient axial play but limited by the bearing faces of the toothed wheel 23 and the stop plate 5,.

I1 est aisé de voir que le montage des deux engrenages b mouvement circulaire37 & 45 entre la roue dentée 23 et la plaque d'arrêt 55 est un montage simple et économique pour la réalisation de ces réducteurs à excentriques, l'excentrique double 17 étant parfaitement entrainé en rotation par la roue dentée 23 9 l'aide du pion 50.  It is easy to see that the assembly of the two gears b circular movement 37 & 45 between the toothed wheel 23 and the stop plate 55 is a simple and economical assembly for the production of these eccentric reducers, the double eccentric 17 being perfectly rotated by the toothed wheel 23 9 using the pin 50.
