Title (EN) HYDRAULIC MACHINE HAVING AXIALLY JOINED LATERAL PLATES ON BOTH SIDES OF GEARWHEEL AND GEAR RING, WHICH PLATES MOVE JOINTLY WITH THE GEARWHEEL OR THE GEAR RING
(FR) MACHINE HYDRAULIQUE A PLAQUES LATERALES RELIEES EN POSITION AXIALE, PLACEES DES DEUX COTES D'UNE ROUE DENTEE ET D'UN ANNEAU DENTE ENTRAINANT DES MOUVEMENTS SOLIDAIRES AVEC CES PLAQUES
Abstract: front page image
(EN)A hydraulic machine (1) is disclosed, having a gearwheel (4), which is arranged on a shaft (2) so that they rotate together and which has a first external toothing (5), a gear ring (7), which has a second external toothing (8) and a first internal toothing (6) which engages with the first external toothing (5), a toothed rim (10), which has a second internal toothing (9) that engages with the second external toothing (8), and having a commutation arrangement for supplying and discharging in the correct order hydraulic fluid in pressure pockets which are formed in the first and/or second toothed coupling in each case between external and internal toothing. It is desirable to be able to improve the operational behaviour of such a machine. For that purpose, on both axial sides of gearwheel (4) and gear ring (7) there is a respective lateral plate (34, 37), which plates are joined axially to one another and move jointly with the gearwheel (4) or the gear ring (7).
(FR)L'invention concerne une machine hydraulique (1) dans laquelle une roue dentée (4) est disposée sur un axe (2) définissant une rotation commune et se présentant comme suit, depuis le centre: première denture externe (5), anneau denté (7) à seconde denture externe (8) et à première denture interne (6) qui est en prise avec la première denture externe (5), couronne dentée (10) à seconde denture interne (9) qui est en prise avec la seconde denture externe (8). La machine est dotée d'un système de commutation qui permet d'envoyer et de décharger dans l'ordre correct un fluide hydraulique à l'intérieur des poches de pression résultant du couplage en première et/ou en seconde denture, toujours entre denture externe et denture interne. Il est souhaitable d'améliorer si possible le fonctionnement d'une telle machine. A cet effet, on place en position axiale de part et d'autre de la roue dentée (4) et de l'anneau denté (7) des plaques latérales (34, 37) qui sont reliées axialement l'une à l'autre et dont les mouvements sont solidaires de ceux de la roue dentée (4) ou de l'anneau denté (7).
