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.

Claims (8)
- Antriebssystem zum Liefern einer Ausgangsdrehung, welches Antriebssystem eine Drehtrommel (10) zum Wickeln eines Kabels aufweist, einen elektrischen Motor (20) mit einer Ausgangswelle (22), die betriebsmäßig für den Antrieb der Trommel (10) verbunden ist, wobei der elektrische Motor (20) an Lagern (53) montiert und innerhalb der Trommel (10) angeordnet ist, welche Trommel auch einen vom elektrischen Motor (20) angetriebenen Getriebesatz (24,26,38) enthält, das ein Innenzahnrad (40) an der Innenfläche der Trommel (10) antreibt, um die letztere zu treiben;
dadurch gekennzeichnet, daß das Antriebssystem auch einen koordinierten Hydraulikausgang bereitstellt, der durch den elektrischen Motor (20) erreicht wird, der gleichzeitig mit dem Antrieb der Trommel (10) auch ein hydraulisches, in der Trommel (10) aufgenommenes Krafterzeugungssystem (21) antreibt, sowie hydraulische Leitungen (50, 52) aufweist, die das hydraulische Krafterzeugungssystem (21) inklusive einer Pumpe (54), einer Verteilerkonstruktion (42) mit einem ersten und einem zweiten Entlastungsventil (60,62) und einem hydraulischen Fluidakkumulator (44, 45) verbinden, die alle innerhalb der Trommel (10) sind. - Antriebssystem nach Anspruch 1, bei dem das Krafterzeugungssystem (21) ferner aufweist:
ein Paar von Rückschlagventilen (67,76), die jeweils zu einem Paar von Entlastungsventilen (68,78) parallelgeschaltet und diesen entgegengerichtet sind, wobei das erste Rückschlagventil (67) und das Entlastungsventil (68) eine erste Hochdruckleitung (56) mit einer dritten Leitung (50) verbinden, und das zweite Rückschlagventil (76) und das Entlastungsventil (78) eine zweite Hochdruckleitung (58) mit einer vierten Leitung (52) verbinden, und die dritte und die vierte Leitung (50,52) sich vom Inneren der Trommel (10) zu einer dazu externen hydraulischen Einrichtung (47,49) erstrecken. - Antriebssystem nach Anspruch 2, bei dem das Paar von Rückschlagventilen (67,76) und das Paar von Entlastungsventilen (68,78) ebenfalls innerhalb der Verteilerkonstruktion (42) innerhalb der Trommel (10) eingeschlossen sind.
- Antriebssystem nach Anspruch 2, bei dem der elektrische Motor (20) eine sich über seine beiden Enden erstreckende Welle (22) aufweist und der Getriebesatz (24, 26, 38) an einem Ende der Welle (22) angetrieben ist und die Pumpe (54) am gegenüberliegenden Ende der Welle (22) angetrieben ist.
- Antriebssystem nach Anspruch 4, bei dem der elektrische Motor (20) reversibel ist, um die Drehrichtung der Trommel (10) und die Richtung der Pumpe (54) umzukehren.
- Antriebssystem nach Anspruch 2, bei dem der elektrische Motor (20) eine koaxial befestigte Kupplungs- (124) und eine Bremseinheit (126) aufweist, welche Kupplungseinheit (124) wahlweise in Betrieb setzbar ist, um den Betrieb der Pumpe (54) ohne gleichzeitige Drehung der Trommel (10) zu gestatten.
- Antriebssystem nach Anspruch 2, bei dem die Entlastungsventile (68,78) zum Blockieren der Strömung von der hydraulischen Einrichtung (47,49) arbeiten, wenn die Pumpe (54) nicht in Betrieb ist.
- Antriebssystem nach Anspruch 2, bei dem die hydraulische Einrichtung ein in einem Zylinder (47) enthaltener hydraulischer Kolben (49) ist.
