In der Figur 1 ist eine Schnittansicht eines erfindungsgemäßen Kettenzugs 1 dargestellt. Der Kettenzug 1 wird von einem elektrischen Antriebsmotor 2 FIG. 1 shows a sectional view of a chain hoist 1 according to the invention. The chain hoist 1 is powered by an electric drive motor. 2
angetrieben, der mit seinem abtriebsseitigen Ende an einem Gehäuse 3 des driven, with its output side end to a housing 3 of the
Kettenzuges 1 befestigt ist. In dem Gehäuse 3 sind eine Rutschkupplung 4, ein Getriebe 5 und ein Kettenrad 6 aufgenommen. Der Antriebsmotor 2 weist eine Motorwelle 2a auf, die mit ihrem abtriebsseitigen Ende über die Rutschkupplung 4 mit dem Getriebe 5 verbunden ist. Die Rutschkupplung 4 besteht im Wesentlichen aus einem ersten Kupplungselement 4a und einem zweiten Kupplungselement 4b, die über einen Reibbelag 4c (siehe Figur 2) miteinander im Eingriff stehen. Das erste Kupplungselement 4a ist konzentrisch zu der Motorwelle 2a und auf deren abtriebsseitigen Ende drehfest angeordnet. Das zweite Kupplungselement 4b ist konzentrisch zu einer Getriebeeingangswelle 5a und auf deren ersten Ende drehfest angeordnet. Hierbei sind die Motorwelle 2a und die Getriebeeingangswelle 5a in deren Längsrichtung gesehen hintereinander und konzentrisch zueinander angeordnet. An dem gegenüber liegenden zweiten Ende ist die Chain hoist 1 is attached. In the housing 3, a slip clutch 4, a gear 5 and a sprocket 6 are added. The drive motor 2 has a motor shaft 2 a, which is connected with its output side end via the slip clutch 4 to the transmission 5. The slip clutch 4 consists essentially of a first coupling element 4a and a second coupling element 4b, which are mutually engaged via a friction lining 4c (see FIG. 2). The first coupling element 4a is arranged concentrically with respect to the motor shaft 2a and on the output side end in a rotationally fixed manner. The second coupling element 4b is concentric with a transmission input shaft 5a and rotationally fixed on its first end arranged. Here, the motor shaft 2a and the transmission input shaft 5a seen in the longitudinal direction are arranged one behind the other and concentric with each other. At the opposite second end is the
Getriebeeingangswelle 5a in einer Außenwand 3a des Gehäuses 3 gelagert. An diesem zweiten Ende greift eine elektrisch lösbare Bremse 7 an, die sich außen an der Außenwand 3a abstützt. Die Bremse 7 ist unter einer Abdeckung 8 angeordnet, die an der Außenseite der Außenwand 3a befestigt ist. Die Abdeckung 8 bietet ausreichend Raum um Elektrik- und/oder Elektronikkomponenten geschützt unterzubringen. Transmission input shaft 5a mounted in an outer wall 3a of the housing 3. At this second end engages an electrically releasable brake 7, which is supported on the outside of the outer wall 3a. The brake 7 is disposed under a cover 8 which is fixed to the outside of the outer wall 3a. The cover 8 provides sufficient space to accommodate electrical and / or electronic components protected.
Um die Rutschkupplung 4 einstellen zu können und das zweite Kupplungselement 4b in Richtung des ersten Kupplungselements 4a vorspannen zu können, ist einerseits die Getriebeeingangswelle 5a in deren Axialrichtung verschiebbar gelagert und stützt sich andererseits über ein Federelement 9 an der Innenseite der Außenwand 3a ab. Des Weiteren ist die Getriebeeingangswelle 5a als Ritzelwelle mit einem ersten Zahnrad 10a ausgebildet, das mit einem zweiten Zahnrad 10b des Getriebes 3 kämmt. Die beiden Zahnräder 10a, 10b bilden somit die erste Getriebestufe. In order to set the slip clutch 4 and to bias the second coupling element 4b in the direction of the first coupling element 4a, on the one hand the transmission input shaft 5a slidably mounted in the axial direction and on the other hand is supported via a spring element 9 on the inside of the outer wall 3a. Furthermore, the transmission input shaft 5a is formed as a pinion shaft with a first gear 10a, which meshes with a second gear 10b of the transmission 3. The two gears 10a, 10b thus form the first gear stage.
Besonders vorteilhaft ist, wenn das erste Zahnrad 10a der Getriebeeingangswelle 5a mit einer Schrägverzahnung in der Art ausgebildet ist, dass bei Betrieb des It is particularly advantageous if the first gear 10a of the transmission input shaft 5a is formed with a helical toothing in such a way that during operation of the
Kettenzugs 1 die durch die Schrägverzahnung bewirkte Axialkraft in Längsrichtung der Getriebeeingangswelle 5a zu einer Reibkraftverstärkung der Rutschkupplung 4 im Hubbetrieb führt. Hierdurch kann ohne Veränderung der Einstellung des  Chain hoist 1, the axial force caused by the helical gear in the longitudinal direction of the transmission input shaft 5a leads to a Reibkraftverstärkung the slip clutch 4 in the lifting operation. This can be done without changing the setting of
Auslösemoments der Rutschkupplung 4 beim Betrieb des Kettenzugs 1 gegenüber dem Stillstand des Kettenzugs 1 eine automatische Veränderung des Tripping torque of the friction clutch 4 during operation of the chain hoist 1 relative to the standstill of the chain hoist 1 an automatic change of
Auslösemoments herbeigeführt werden. Hiermit geht der Vorteil einher, dass bei einer Umkehr der Kraftflussrichtung im Getriebe 5 durch eine Verhakung der Kette auf der Nichtlastseite dann die Axialkraft der Verzahnung der Vorspannung des  Triggering moments are brought about. This is associated with the advantage that in a reversal of the power flow direction in the transmission 5 by a hooking of the chain on the non-load side then the axial force of the teeth of the bias of
Federelements 9 entgegenwirkt und das die Rutschkupplung 4 auslösende Counteracts spring element 9 and that the slip clutch 4 triggering
Drehmoment heruntergesetzt wird. Die Gefahr einer Beschädigung des Kettenzuges 1 wird dadurch verringert. Torque is lowered. The risk of damage to the chain hoist 1 is thereby reduced.
Des Weiteren weist das Getriebe 5 eine Getriebeausgangswelle 5b auf, die parallel zur Getriebeeingangswelle 5a verläuft und seitlich zu dieser versetzt in dem Gehäuse 3 gelagert ist. Abtriebsseitig ist an der Getriebeausgangswelle 5b drehfest und konzentrisch zu dieser das Kettenrad 6 angeordnet, mit dem eine Kette 1 1 des Kettenzuges 1 in Hub- und Senkrichtung bewegt werden kann. Die Furthermore, the transmission 5 has a transmission output shaft 5b which runs parallel to the transmission input shaft 5a and is mounted laterally offset in the housing 3. The output side is rotatably on the transmission output shaft 5b and arranged concentrically to this the sprocket 6, with a chain 1 1 of the chain hoist 1 can be moved in the lifting and lowering. The
Getriebeeingangswelle 5a und die Getriebeausgangswelle 5b sind in einem Transmission input shaft 5a and the transmission output shaft 5b are in one
Getrieberaum 5c angeordnet, der von dem Gehäuse 3 begrenzt ist. Der Getrieberaum 5c ist in üblicher Weise mit einem Getriebeöl befüllt. Gear chamber 5 c arranged, which is bounded by the housing 3. The gear chamber 5c is filled in the usual way with a transmission oil.
Der Kettenzug 1 kann mittels einer nicht dargestellten Öse, die außen und oben an dem Gehäuse 3 angreift, an einer gewünschten Stelle aufgehängt werden. Die Figur 2 zeigt eine Ausschnittsvergrößerung von Figur 1 aus dem Bereich derThe chain hoist 1 can be hung at a desired location by means of an eyelet, not shown, which engages the outside and top of the housing 3.

Zwischen der Innenfläche 12a der Bohrung 12 und der Außenfläche 4d der Rutschkupplung 4 verbleibt ein um die Rutschkupplung 4 herum laufender Spalt s, der etwa im Bereich von 1 mm bis 5 mm liegt. Hierbei erstreckt sich die Bohrung 12 mit ihrer Bohrungswand 12b ausgehend von der Zwischenwand 3b in Richtung des Antriebsmotors 2 und die Bohrungswand 12b bildet eine Art Ansatz an der Zwischenwand 3b aus. Slip clutch 4 of the chain hoist 1. It can be seen that the slip clutch 4 is arranged in a bore 12 in an intermediate wall 3b of the housing 3. The bore 12 has a circular cross-section with an inner surface 12a and an inner diameter i, which is slightly larger than the outer diameter d of the slip clutch 4. The slip clutch 4 is substantially cylindrical with a stepped outer surface 4d. Between the inner surface 12a of the bore 12 and the outer surface 4d of the slip clutch 4, a gap s running around the slip clutch 4 remains, which is approximately in the range of 1 mm to 5 mm. Here, the bore 12 extends with its bore wall 12b, starting from the intermediate wall 3b in the direction of the drive motor 2 and the bore wall 12b forms a kind of approach to the intermediate wall 3b.
Die Rutschkupplung 4 besteht im Wesentlichen aus dem ersten Kupplungselement 4a und dem zweiten Kupplungselement 4b. Das auf der Motorwelle 2a befestigte erste Kupplungselement 4a hat im Wesentlichen die Form einer Hülse mit einem The slip clutch 4 consists essentially of the first coupling element 4a and the second coupling element 4b. The mounted on the motor shaft 2a first coupling element 4a has substantially the shape of a sleeve with a
Flanschansatz, die in ein erstes Befestigungsteil 4e und ein flanschartige erstes Kupplungsscheibenteil 4f aufgeteilt werden kann. Der Befestigungsteil 4e und der Kupplungsscheibenteil 4f unterscheiden sich im Wesentlichen durch ihre voneinander verschiedenen Außendurchmesser a, b. Der Außendurchmesser a des  Flange approach, which can be divided into a first fastening part 4e and a flange-like first coupling disk part 4f. The fastening part 4e and the coupling disk part 4f differ essentially in their different outer diameters a, b. The outer diameter a of
Befestigungsteils 4e geht sprungartig in den Außendurchmesser b des Fastening part 4e goes abruptly in the outer diameter b of
Kupplungsscheibenteils 4f über. Hierdurch wird an dem Kupplungsscheibenteils 4f eine ringförmige Anlagefläche 4g geschaffen, an der der Innenring 13a eines  Clutch disk part 4f over. As a result, an annular contact surface 4g is provided on the coupling disk part 4f, on which the inner ring 13a of a
Kugellagers 13 anliegt, über das das Befestigungsteil 4e und somit die darin eingesteckte Motorwelle 2a an der Innenfläche 12a der Bohrung 12 gelagert wird. An das Kugellager 13 in Richtung des Antriebsmotors 2 gesehen angrenzend ist ein Dichtring 14 auf das Befestigungsteil 4e aufgesteckt, der sich außen an der Ball bearing 13 is applied, via which the fastening part 4e and thus the motor shaft 2a inserted therein is mounted on the inner surface 12a of the bore 12. Adjacent to the ball bearing 13 in the direction of the drive motor 2 is a Sealing ring 14 mounted on the mounting part 4 e, the outside of the
Innenfläche 12 der Bohrung 12 abstützt und somit das Befestigungsteil 4e in der Bohrung 12 und somit den Getrieberaum 5c abdichtet. Des Weiteren ist der Figur 2 zu entnehmen, dass das Kupplungsscheibenteil 4f der Kupplung 4 eine umlaufende Umfangsfläche 4h aufweist, die nicht eben ausgebildet ist sondern mit Vertiefungen 15. Die Vertiefungen 15 haben die Funktion die Inner surface 12 of the bore 12 is supported and thus the fastening part 4e in the bore 12 and thus the transmission chamber 5c seals. Furthermore, it can be seen from Figure 2, that the coupling disk part 4f of the clutch 4 has a peripheral peripheral surface 4h, which is not flat but with recesses 15. The recesses 15 have the function of
Umfangsfläche 4h zu vergrößern und somit die Abfuhr der Wärme von der Kupplung 4 in das Getriebeöl zu verbessern. Vorzugsweise sind diese Vertiefungen 15 als umlaufende Gewindegänge ausgebildet, wobei die Gängigkeit der Gewindegänge so gewählt ist, dass im Hubbetreib des Kettenzuges 1 von den Gewindegängen Enlarge peripheral surface 4h and thus improve the removal of heat from the clutch 4 in the transmission oil. Preferably, these recesses 15 are formed as circumferential threads, the movement of the threads is chosen so that in the Hubbetreib the chain hoist 1 of the threads
Getriebeöl in die Bohrung 12 gefördert wird. Auch im Senkbetrieb findet eine Transmission oil is conveyed into the bore 12. Even in the lowering mode finds one
Förderung stört, da die Gewindegänge das Getriebeöl aus der Bohrung 12 heraus fördern und somit frisches Getriebeöl aus dem Getrieberaum 5c nachströmt. Promotion disturbs because the threads promote the gear oil out of the bore 12 and thus flows fresh gear oil from the gear chamber 5c.
Außerdem ist das Kupplungsscheibenteil 4f in Bezug auf die erforderliche In addition, the clutch pulley part 4f is required in relation to the required one
mechanische Festigkeit überdimensioniert, um durch die dadurch vorhandene Masse die Aufnahme der Reibungswärme der Kupplung 4 verbessert wird. Durch die oversized mechanical strength in order to improve the absorption of frictional heat of the clutch 4 by the mass thus existing. By the
Verbesserung der Kühlung kann das erste Kupplungsscheibenteil 4f vollständig in der Bohrung 12 angeordnet sein. To improve the cooling, the first coupling disk part 4 f can be arranged completely in the bore 12.
Auch ist es im Sinne der Erfindung möglich, die Form und Steigung der Also, it is within the meaning of the invention possible, the shape and slope of the
Gewindegänge zu variieren. Denkbar sind auch mehrgängige Gewinde oder Nuten, die in Längsrichtung der Motorwelle ausgerichtet sind, um ein Art Schaufelradeffekt zu erreichen. To vary threads. Also conceivable are multi-start threads or grooves, which are aligned in the longitudinal direction of the motor shaft in order to achieve a kind of paddle wheel effect.
Im Gegensatz zu dem ersten Kupplungselement 4a sind die Anforderungen an eine ausreichende Kühlung des zweiten Kupplungselements 4b leichter zu erfüllen, da das zweite Kupplungselements 4b an einem dem Getrieberaum 5c zugewandten Ende der Bohrung 12 angeordnet ist und somit die Reibungswärme leicht an das Getriebeöl abgeben kann. Das zweite Kupplungselement 4b weist grundsätzlich die gleiche Bauform wie das erste Kupplungselement 4a auf, wobei die Vertiefungen 15 und die Überdimensionierung nicht erforderlich sind. Entsprechender Weise hat das zweite Kupplungselement 12b die Form einer Hülse mit einem Flanschansatz, die in ein zweites Befestigungsteil 4i und ein flanschartiges zweites Kupplungsscheibenteil 4j aufgeteilt werden kann. Der zweite Befestigungsteil 4i und der zweite Kupplungsscheibenteil 4j unterscheiden sich im Wesentlichen durch ihre voneinander verschiedenen Außendurchmesser e, f. Der Außendurchmesser e des In contrast to the first coupling element 4a, the requirements for sufficient cooling of the second coupling element 4b are easier to fulfill, since the second coupling element 4b is arranged on a gear chamber 5c facing the end of the bore 12 and thus can easily deliver the frictional heat to the transmission oil. The second coupling element 4b basically has the same construction as the first coupling element 4a, wherein the recesses 15 and the oversizing are not required. Correspondingly, the second coupling element 12b has the form of a sleeve with a flange attachment, which can be divided into a second fastening part 4i and a flange-like second coupling disk part 4j. The second attachment part 4i and the second Clutch disk part 4j differ essentially by their different outer diameters e, f. The outer diameter e of
Befestigungsteils 4i geht sprungartig in den Außendurchmesser f des Fastening part 4i goes abruptly in the outer diameter f of
Kupplungsscheibenteils 4j über. Hierdurch wird an dem zweiten Clutch disk part 4j over. This is at the second
Kupplungsscheibenteils 4j eine ringförmige zweite Kupplungsfläche 41 geschaffen, an der der ringförmige Reibbelag 4c aufgeklebt ist. Der Reibbelag 4c liegt mit seiner gegenüber liegenden Reibfläche an der ersten Kupplungsfläche 4k des zweiten Kupplungsscheibenteils 4j an. Die erste ringförmige Kupplungsfläche 4k ist parallel zur Anlagefläche 4g des ersten Kupplungsscheibenteil 4f angeordnet und liegt an der der Anlagefläche 4g gegenüber liegenden Seite des ersten Kupplungsscheibenteil 4f. Clutch disc part 4j an annular second coupling surface 41 created on which the annular friction lining 4c is glued. The friction lining 4c abuts with its opposing friction surface on the first coupling surface 4k of the second coupling disk part 4j. The first annular coupling surface 4k is arranged parallel to the contact surface 4g of the first coupling disk part 4f and lies on the side of the first coupling disk part 4f opposite the contact surface 4g.
Des Weiteren weist das zweite Kupplungsscheibenteil 4j eine zu der zweiten Furthermore, the second clutch disk part 4j has one to the second
Kupplungsfläche 41 parallele und hierzu gegenüber liegende Ringfläche 4m auf, die am Ende der Bohrung 12 angeordnet ist und dem Getrieberaum 5c zugewandt ist. Entsprechend ist das zweite Kupplungselement 4b gut über deren Ringfläche 4m zu kühlen. Coupling surface 41 parallel and opposed thereto annular surface 4m, which is arranged at the end of the bore 12 and the gear housing 5c facing. Accordingly, the second coupling element 4b to cool well over the annular surface 4m.
Auch zeigt die Figur 2, dass das zweite Kupplungselement 4b mit seinem zweiten Befestigungsteil 4i in eine Kupplungsbohrung 16 im Innern des ersten Also shows the figure 2, that the second coupling element 4b with its second attachment part 4i in a coupling bore 16 in the interior of the first
Kupplungsscheibenteils 4f eingeschoben ist und über ein Nadellager 17 gelagert ist. Entsprechend ist der Außendurchmesser e des zweiten Befestigungsteil 4i kleiner als der Innendurchmesser der Kupplungsbohrung 16. Hierdurch kann dann der Reibbelag 4c zur Anlage an der ersten Kupplungsfläche 4k des ersten Kupplungselementes 4a kommen. Clutch disk part 4f is inserted and is mounted on a needle bearing 17. Accordingly, the outer diameter e of the second fastening part 4i is smaller than the inner diameter of the coupling bore 16. As a result, the friction lining 4c can then come to bear against the first coupling surface 4k of the first coupling element 4a.
