Definitions
- shaft 22 is connected to an hydraulic power generating system 21 and in particular to an hydraulic pump thereof which is part of a manifold structure 42.
- an accumulator 44 including a piston 46 and a spring 48.
- the manifold 42 including the motor-driven pump, supplies hydraulic fluid under pressure to an external actuating cylinder 47 including a piston 49 through a pair of conduits 50, 52.
- This manifold is described in greater detail in connection with Figures 3 through 8.
- Also part of manifold 42 is an axially extending boss 51 including a bearing 53 supporting one end of drum 10.
- initial operation of the motor may occur with the clutch 124 disengaged such that the pump turns but the drum does not turn.
- On the return part of the cycle it may be that the operator will want the drum 10 to operate at the outset or later in the cycle.
- rotation of the drum 10 in a given direction always results in the pump 54 moving in a particular direction because they are effectively being driven from the same shaft.
- the brake 126 serves primarily to hold the shaft 122 in a desired position and to prevent it from rotating as might be the case if some extraneous force were to tension the cables.

Abstract
Claims (8)
- Système d'entraînement à sortie rotative, ledit système comportant un tambour rotatif (10) pour enrouler un câble, un moteur électrique (20) comportant un arbre de sortie (22) convenablement relié pour entraîner ledit tambour (10), dans lequel ledit moteur électrique (20) est monté sur des roulements (53) et disposé à l'intérieur dudit tambour (10), ledit tambour contenant également un jeu d'engrenages (24, 26, 38) entraîné par ledit moteur électrique (20) et entraînant un engrenage interne (40) disposé sur la surface interne du tambour (10) pour entraîner ce dernier;
caractérisé en ce que ledit système d'entraînement présente également une sortie hydraulique coordonnée obtenue par le fait que ledit moteur électrique (20) de façon simultanée avec l'entraînement du tambour entraîne un dispositif générateur d'énergie hydraulique (21) monté dans ledit tambour (10), et des conduites hydrauliques (50, 52) connectées audit générateur d'énergie hydraulique (21), ledit générateur d'énergie hydraulique (21) comportant une pompe (54), une structure de tubulure multiple (42) équipée d'une première et d'une seconde vanne de décharge (60, 62) et un accumulateur hydraulique (44, 45), tous disposés à l'intérieur du tambour (10). - Système d'entraînement selon la revendication 1 dans lequel le dispositif générateur d'énergie hydraulique (21) comporte de plus:
une paire de vannes anti-retour (67, 76) couplées chacune en parallèle et en opposition avec l'une de deux vannes de décharge (68, 78) , la première vanne anti-retour (67) et la vanne de décharge (68) reliant une première conduite haute pression (56) à une troisième conduite, et ladite seconde vanne anti-retour (76) et la vanne de décharge (78) reliant une seconde conduite haute pression (58) à une quatrième conduite, lesdites troisième et quatrième conduites (50, 52) s'étendant depuis l'intérieur du tambour (10) vers un dispositif hydraulique (47, 49) externe audit tambour. - Système d'entraînement selon la revendication 2, dans lequel ladite paire de vannes anti-retour (67, 76) et lesdites vannes de décharge (68, 78) sont également montées dans la structure de tubulure multiple (42) dans ledit tambour (10).
- Système d'entraînement selon la revendication 2, dans lequel ledit moteur électrique (20) comporte un arbre (22) se projetant à partir des deux extrémités du moteur, ledit jeu d'engrenages (24, 26, 38) étant entraîné à l'une des extrémités dudit arbre (22) et ladite pompe (54) étant entraînée à l'autre extrémité dudit arbre (22).
- Système d'entraînement selon la revendication 4, dans lequel ledit moteur électrique (20) est réversible pour inverser le sens de rotation dudit tambour (10) et la direction de ladite pompe (54).
- Système d'entraînement selon la revendication 2, dans lequel ledit moteur électrique (20) comporte un ensemble d'embrayage (124) et un ensemble de frein (126) montés coaxialement, ledit ensemble d'embrayage (124) étant mis en oeuvre sélectivement pour permettre le fonctionnement de la pompe (54) sans rotation simultanée dudit tambour (10).
- Système d'entraînement selon la revendication 2, dans lequel lesdites vannes de décharge (68, 78) sont destinées à bloquer le débit de fluide à partir du dispositif hydraulique (47, 49) lorsque la pompe (54) est à l'arrêt.
- Système d'entraînement selon la revendication 2, dans lequel ledit dispositif hydraulique est constitué d'un piston hydraulique (49) disposé dans un cylindre (47).
