Abstract
Description
Rutschelement. Slide element.
Beschreibung: In der Technik, speziell im Maschinen- und Anlagenbau, werden immer wieder Antriebe benötigt, welche bei überschreiten eines gewissen Drehmoments durchrutschen können ohne Schaden zu nehmein; sei es um nachfolgende Teile zu schützen oder um z.B. gegen einen Festanschlag fahren zu können um bestimmte Längen oder Teilungen zu erreichen; wie z.B. beim automatischen Ablängen, zuführen von Teilen, bei Tür- und Torantrieben u.ä.Description: In technology, especially in mechanical and plant engineering, drives are always required, which when a certain torque is exceeded can slip through without being damaged; be it to protect the following parts or, for example, to be able to move against a fixed stop by certain lengths or To achieve divisions; such as automatic cutting to length, feeding of parts, for door and gate drives, etc.
Zur Lösung dieser Aufgaben gibt es am Markt mehr oder weniger brauchbare Maschinenelemente wie z.B. mechanische Rutschkupplungen, Wirbelstromkupplungen u.a.There are more or less useful ones on the market for solving these tasks Machine elements such as mechanical slip clutches, eddy current clutches, etc.
Wärend Rutschkupplungen und dergl. einer Abnützung unterliegen und im eingebauten Zustand in der Regel nicht von außen nachgestellt werden können, sind Wirbelstromkupplungen sehr aufwendig und somit teuer.During slipping clutches and the like. Subject to wear and tear and Can usually not be readjusted from the outside when installed, eddy current clutches are very complex and therefore expensive.
Der Erfindung liegt die Aufgabe zugrunde, ein einfaches Rutschelement zu schaffen, welches ein durchrutschen bei erreichen eines einstellbaren Drehmoments über einen längeren Zeitraum erlaubt und bei welchem das Drehmoment, im eingebauten Zustand, von außen verstellt werden kann.The invention is based on the object of a simple slide element to create a slip when reaching an adjustable torque Allowed over a longer period of time and at which the torque in the built-in State that can be adjusted from the outside.
Dies wird dadurch erreicht, indem, wie in der Zeichnung Fig. 1 dargestellt, eine Kette 2), z.B. Rollenkette, über eine glatte Scheibe 3), also ohne Zähne, läuft und mit einem Kettenritzel 1) angetrieben wird.This is achieved by, as shown in the drawing Fig. 1, a chain 2), e.g. roller chain, runs over a smooth disk 3), i.e. without teeth and is driven by a chain pinion 1).
Bei Erzeugung einer Kettenspannung, z.B. über das Kettenritzel 1) mit Federkraft 5), wird die Scheibe 3) mit einem bestimmten Drehmoment mitgenommen, welches umso höher ist, je größer die Vorspannung 5) wird.When generating chain tension, e.g. via the chain pinion 1) with spring force 5), the disc 3) is driven with a certain torque, which is the higher, the greater the preload 5).
Die Vorspannung kann auch, wie in Fig. 2 g igt, durch federnde Segmente 4) in der Scheibe 3) erreicht werden, in diesem Fall umschlingt die Kette 2) die Scheibe 3) vollständig, wärend das Antriebs-Kettenritzel 1) von außen in die Kette 2) eingreift. Je nach Federkraft 5) wird nun wieder ein bestimmtes Drehmoment übertragen.The preload can also, as shown in FIG. 2, by resilient segments 4) in the disk 3), in this case the chain 2) wraps around the Disc 3) completely, while the drive chain sprocket 1) from the outside into the chain 2) intervenes. Depending on the spring force 5), a certain torque is now transmitted again.
Fig. 3 zeigt eine einfache und somit preiswerte Getriebemotorausführung, bei welcher das Rutschelement eingebaut ist und das Drehmoment über die Mutter 6) jederzeit, also wärend des Laufs als auch wärend des Stillstands, von außen eingestellt werden kann. Es sind: 1) Kettenritzel, 2) Rollenkette, 3) Scheibe, 5) Tellerfederpakket, 6) Einstellmutter, 7) Antriebsmotor, 8) Abtriebswelle.Fig. 3 shows a simple and thus inexpensive geared motor design, in which the sliding element is installed and the torque via the nut 6) set externally at any time, i.e. during the run as well as during the standstill can be. There are: 1) chain pinion, 2) roller chain, 3) washer, 5) disc spring package, 6) adjusting nut, 7) drive motor, 8) output shaft.
