Abstract
Description
Erfindung betrifft Antriebselemente in sehr schlanker Form und unterschiedlichen Längen, die aus Seil-Maschinen erstellt sind die erfindungsgemäß so aufgebaut sind, daß relativ große Lasten sehr ekonomisch gezogen, geschoben, gehoben und gesengt werden können.The invention relates to drive elements in a very slim form and different Lengths that are created from rope machines that are constructed according to the invention that relatively large loads were pulled, pushed, lifted and singed very economically can be.
Insbesondere handelt es sich dabei um Antriebselemente für Türen und Tore mit automatischem verschließen, Sektional-Tore, Rolltore, Hofeinfahrten, Klappen, Ruder, Landeklappen, Servolenkungen und gesamte Automatisierungssektor der Haustechnik, Industrie so wie, KFZ, LKW Baumaschinen, Landwirtschaftliche Maschinen Bereich. Elektroschlösser und Selbst handbetriebener Wagenheber ist realisierbar.In particular, these are drive elements for doors and gates with automatic closing, sectional gates, roller gates, courtyard entrances, flaps, oars, Flaps, power steering and the entire automation sector of building services, Industry such as, automotive, truck construction equipment, agricultural machinery area. Electric locks and even hand-operated jacks can be implemented.
Bekannt sind unterschiedliche Antriebselemente die ihren Dienst gut tun, sind jedoch von der Ausführung für bestimmte Anwendungen und vor allem bei Bewältigung bestimmter Arbeiten optisch zu groß dimensioniert. Es ist klar, daß eine gewisse Kraftabgabe auch ihren Tribut fordert. Es ist fast immer so, daß Getriebe-Ausgang eine Achse zur Verfügung steht und wenn dann noch ein Gestänge bei Antrieb eine Klappe eingesetzt wird, verringert sich Antriebskraft um die Länge des Gestänges.Various drive elements that do their job well are known, however from the execution for certain applications and especially when coping certain works optically too large. It is clear that a certain Power delivery also takes its toll. It is almost always the case that gearbox output an axis is available and if there is still a linkage when driving one When the flap is used, the driving force is reduced by the length of the boom.
Erfindungsgemäß wird vorgeschlagen, Golub-Schubgetriebe einzusetzen, die in der Form äußerst klein gehalten sind und in den Ausgangskräften kein Vergleich auf dem Markt haben. Hierbei handelt sich um ein selbst justierendes und spielfreies Antriebsgebilde bei dem Ausgangskräfte einstellbar sind und Geschwindigkeiten von 5 mm/s bis 0,5 m/s leicht kombinierbar. Ausgegebene Schubkräfte sind zum Beispiel 3000 N die dann mit einem Gestänge an eine Klappe übertragen wird. Ob Gestänge 1 m oder 3 m beträgt ist doch die übertragene Kraft immer noch 3000 N als Schubkraft vorhanden.According to the invention, it is proposed to use Golub thrust gear, which in the Form are kept extremely small and in the initial forces no comparison on the Have market. This is a self-adjusting and play-free Drive structures with adjustable output forces and speeds of 5 mm / s to 0.5 m / s can be easily combined. Output thrust are, for example 3000 N which is then transferred to a flap with a linkage. Whether boom 1 m or 3 m, the transmitted force is still 3000 N as thrust available.
Antriebsmotoren können ohne Untersetzung und mit angewendet werden. Drive motors can be used without reduction and with.
Antriebrad ist 3fach untersetzt, Differentialzahnräder weisen 2 mm Differenz auf und Motorantrieb hat 3000 u/min. Differentialzahnrad bewirkt bei einer Umdrehung 2 mm Schub an dem Schlitten und Differentialzahnrad wird in 1 min. 3000 : 3 gedreht. Das heißt 1000 × 2 mm ergibt einen Schubweg von 2000 mm min. Ob jetzt große oder kleine Zahnräder für die Kraftübertragung angewendet werden ist mehr oder weniger bedeutungslos.The drive wheel has a 3-step reduction, differential gears have a difference of 2 mm and Motor drive has 3000 rpm. Differential gear causes 2 mm in one revolution Thrust on the slide and differential gear is in 1 min. 3000: 3 rotated. That means 1000 × 2 mm results in a stroke of 2000 mm min. Whether big or now Small gears used for power transmission are more or less meaningless.
Abhängig von der Anwendung können Selbsthemmende und Nichtselbsthemmende Ausführungen gefertigt werden.Depending on the application, self-locking and non-self-locking can Designs are manufactured.
Selbsthemmende Schubgetriebe finden Anwendung dort, wo eingestellte Positionen gehalten werden sollen und Nichtselbsthemmende Schubgetriebe werden dort eingesetzt wo in einer Notsituation eine Verstellung der eingestellten Position verändert werden muß.Self-locking thrust gears are used wherever positions are set and non-self-locking thrust gears are used there where an adjustment of the set position is changed in an emergency got to.
Erfindungsgemäß sind ekonomische Vorteile unübersehbar, technisch leicht und mit wenig Materialaufwand realisierbar, bei groß und klein sind gleiche Bauteile anzuwenden und nur die Kette oder andere Antriebselemente werden länger das von einer Meterware abgenommen wird. According to the invention, economic advantages are obvious, technically easy and with little material expenditure can be realized, with large and small the same components apply and only the chain or other drive elements are longer that of a meter goods is removed.
