Abstract

« Rotation d'excentriques » pour transformer le mouvement alternatif des pistons d'un moteur à combustion interne (ou tout engin à pistons) en mouvement circulaire, en place du système « bielle-manivelle » générateur de frottements latéraux dans les cylindres. Le dispositif est constitué d'un plateau tournant portant les cylindres en périphérie et à sa base un pignon central s'engrenant avec un pignon de même diamètre solidaire d'un pignon excentré de même diamètre s'engrenant avec un pignon excentré de même diamètre surmonté d'un arbre central portant les bras de pistons. Grâce aux pignons excentrés, la rotation du plateau provoque un décalage angulaire de +/- Δ degrés générant la course alternative des pistons. Ce dispositif se destine principalement aux moteurs à combustion interne avec gain sensible d'énergie, facilité d'obtention et rapport poids/puissance avantageux (voire aussi pompes, compresseurs, groupes électrogènes, chargeurs permanents ou non de batteries de véhicules électriques, engins volants, etc...)."Rotation eccentrics" to transform the reciprocating pistons of an internal combustion engine (or any piston engine) in circular motion, in place of the system "connecting rod-crank" generating lateral friction in the cylinders. The device consists of a turntable bearing the cylinders peripherally and at its base a central gear meshing with a pinion of the same diameter integral with an eccentric pinion of the same diameter meshing with an eccentric pinion of the same diameter topped a central shaft carrying the arms of pistons. Thanks to the eccentric pinions, the rotation of the plate causes an angular offset of +/- Δ degrees generating the reciprocating stroke of the pistons. This device is intended primarily for internal combustion engines with significant energy gain, ease of obtaining and advantageous weight / power ratio (or even pumps, compressors, generators, permanent chargers or not batteries of electric vehicles, flying machines, etc ...).

Description

La présente invention concerne un dispositif de « rotation d'excentriques » permettant de transformer la course alternative des pistons dans les cylindres en mouvement circulaire. À l'image des moteurs à combustion interne, cette opération est traditionnellement obtenue par l'intermédiaire du classique système « bielle-manivelle » malheureusement générateur d'importants frottements latéraux dans les cylindres.The present invention relates to an "eccentric rotation" device for transforming the reciprocating stroke of the pistons in cylinders in circular motion. Like the internal combustion engines, this operation is traditionally obtained through the classic system "connecting rod-crank" unfortunately generating significant lateral friction in the cylinders.

Le dispositif selon l'invention permet de remédier à ce problème. Il comporte en effet selon une première caractéristique un plateau tournant porteur de cylindres en sa périphérie et d'un pignon à sa base s'engrenant avec un pignon de mêmes caractéristiques solidaire d'un pignon excentré s'engrenant à son tour avec un pignon de mêmes caractéristiques surmonté d'un arbre remontant au centre du plateau pour porter les bras de pistons. Selon des modes particuliers de réalisation : - Quels que soient l'arrangement, la position et la disposition des engrenages, le dispositif selon l'invention repose invariablement sur le décalage angulaire créé par la rotation des pignons excentrés. - La course des pistons est directement 25 proportionnelle à l'excentration des pignons et de la longueur des bras. - Le couple résultant ou nécessaire selon l'application, moteur, pompe compresseur, etc..., est directement proportionnel à la longueur des bras. 30 Le dispositif selon l'invention ne génère aucun autre frottement que celui nécessaire à l'étanchéité des assemblages cylindre-piston. - Dans le cas d'un moteur à combustion interne ou d'une pompe, le système offre un couple 35 plusieurs fois supérieur au système « bielle-manivelle ».The device according to the invention overcomes this problem. It comprises in fact according to a first characteristic a rotating plate carrying cylinders at its periphery and a pinion at its base meshing with a pinion of the same characteristics integral with an eccentric pinion meshing with a pinion of same characteristics surmounted by a tree going up in the center of the plate to carry the arms of pistons. According to particular embodiments: - Whatever the arrangement, the position and the arrangement of the gears, the device according to the invention invariably relies on the angular offset created by the rotation of the eccentric pinions. The stroke of the pistons is directly proportional to the eccentricity of the gears and the length of the arms. - The resulting torque or necessary according to the application, motor, compressor pump, etc ..., is directly proportional to the length of the arms. The device according to the invention generates no other friction than that required for sealing the cylinder-piston assemblies. In the case of an internal combustion engine or a pump, the system offers a torque several times greater than the "crank-rod" system.

La figure 1 représente en coupe le dispositif de l'invention selon une des variantes de réalisation. En référence à cette figure, le dispositif selon l'invention se compose d'un plateau tournant (1) porteur de cylindres (2) en sa périphérie et d'un pignon (3) à sa base s'engrenant avec un pignon (4) de caractéristiques identiques et solidaire d'un pignon excentré (5) s'engrenant avec un pignon excentré (6) de mêmes caractéristiques et surmonté d'un arbre (7) remontant au centre du plateau (1) pour porter les bras (8) et les pistons (9). Cette figure montre en outre la possibilité : - d'arranger par construction la position et la disposition des engrenages sans modifier pour autant le 15 principe du décalage angulaire créé par la rotation des excentriques (5) et (6). - de modifier la course des pistons en faisant varier l'excentricité des pignons (5) et (6) et la longueur des bras (8). 20 - de modifier le couple résultant ou nécessaire selon l'application, moteur, pompe, compresseur, etc..., en influant sur la longueur des bras (8). La figure 2 représente le décalage angulaire créé par la rotation des pignons excentrés (5) et (6).Figure 1 shows in section the device of the invention according to one of the variants. With reference to this figure, the device according to the invention consists of a rotating plate (1) carrying cylinders (2) at its periphery and a pinion (3) at its base meshing with a pinion (4). ) of identical characteristics and integral with an eccentric pinion (5) meshing with an eccentric pinion (6) of the same characteristics and surmounted by a shaft (7) going up to the center of the plate (1) to carry the arms (8). ) and the pistons (9). This figure also shows the possibility: of arranging by construction the position and arrangement of the gears without modifying the principle of the angular offset created by the rotation of the eccentrics (5) and (6). - Change the piston stroke by varying the eccentricity of the gears (5) and (6) and the length of the arms (8). - Change the resulting torque or necessary according to the application, motor, pump, compressor, etc ..., influencing the length of the arms (8). Figure 2 shows the angular offset created by the rotation of the eccentric pinions (5) and (6).

25 Celui-ci passe par une phase positive puis négative, ou l'inverse selon le sens de rotation en suivant une courbe sinusoïdale propice à un aller-retour du piston (9) par rapport au cylindre (2). À titre d'exemple non limitatif, le dispositif 30 selon l'invention pourra très sensiblement restreindre les dimensions couramment usitées en motorisation de véhicules terrestres ou aériens, voire de modélisme. Le dispositif selon l'invention est particulièrement destiné à la motorisation à combustion 35 interne, et au domaine des pompes et compresseurs.This passes through a positive and negative phase, or the opposite in the direction of rotation following a sinusoidal curve conducive to a round trip of the piston (9) relative to the cylinder (2). By way of non-limiting example, the device 30 according to the invention may very substantially restrict the dimensions commonly used in motorization of land or air vehicles, or even model making. The device according to the invention is particularly intended for the internal combustion engine, and the field of pumps and compressors.
