Abstract

L'INVENTION CONCERNE DES DISPOSITIFS D'ENTRAINEMENT. CES DISPOSITIFS SE CARACTERISENT PAR UNE LIAISON PIVOTANTE ENTRE ORGANE D'ENTREE 33 ET ORGANE DE SORTIE 36 QUI COMPREND UN ORGANE INTERMEDIAIRE 46 RELIE AUX ORGANES D'ENTREE ET DE SORTIE PAR UNE ROTULE 44, 56-44, 56 ET DES CRABOTS 40, 54-40, 54 DE MANIERE A COMPENSER LES VARIATIONS D'ALIGNEMENT. APPLICATION: POMPES OU MOTEURS A ENGRENAGES HELICOIDAUX.THE INVENTION CONCERNS TRAINING DEVICES. THESE DEVICES ARE CHARACTERIZED BY A PIVOTING LINK BETWEEN INPUT BODY 33 AND OUTPUT BODY 36 WHICH INCLUDES AN INTERMEDIATE BODY 46 CONNECTED TO THE INPUT AND OUTPUT BODIES BY A BALL 44, 56-44, 56 AND CRABOTS 40, 54 -40, 54 SO AS TO COMPENSATE FOR ALIGNMENT VARIATIONS. APPLICATION: PUMPS OR MOTORS WITH HELICOIDAL GEARS.
