Description
Selbstsperrender Spannring mit gleichbleibender axialerSelf-locking clamping ring with constant axial VorspannkraftPreload
Die bekannten selbstsperrenden Spannringe haben nach dem Einbau nur eine geringe axiale Vorspannkraft, welche auch noch bei temperaturbedingten itängenänderungen des zu spannenden Bolzens nach= läßt und sogar zu Null werden kann. Oft ist auch ein Wackeln der Verbindung allein durch zeitabhängige Längung, z.B. bei Kunststoff* bolzen zu bemerken. Die beschriebene Neuerung kann in gewissen Grenzen auftretende Dehnungen in der mit ihr hergestellten Verbindung ausgleichen und zwar derart, daß dabei die axiale Vorspannkraft für die Praxis als konstant anzusehen ist.The known self-locking clamping rings have only a small axial preload force after installation, which is also applied under temperature-related Changes in length of the bolt to be clamped according to = and can even become zero. Often a wobbling of the connection is caused solely by time-dependent elongation, e.g. with plastic * notice bolts. The innovation described can, within certain limits, occur in the connection made with it compensate in such a way that the axial preload force is to be regarded as constant in practice.
Die Neuerung besteht darin, daß bekannte selbstsperrende Spannringkonstruktionen mit einem axial federnden Teil kombiniert werden» Dieser Teil wird vorzugsweise als federnder konischer Ring, der für r^ich allein gesehen wie eine Tellerfeder wirkt und mit dem eigentlichen sperrenden Ring eine Einheit darstellt, ausgeführt. In Abb. 1 ist ein selbPtsperrender Spannring in Baueinheit mit den beschriebenen federnden Ring dargestellt. Durch entsprechend konstruktive Ausführung des federnden konischen Ringes läßt sich ein günstiges Federkraft P-Federweg s- Verhalten verwirklichen« wie dies von Tellerfedern her schon bekannt ist und prinzipiell in Abb. 2 dargestellt ist. Der Einbau und die Montage der beschriebenen Neuerung erfolgt auf gleiche Art wie bei herkömmlichen selbstsperrenden Spannringen. Ein Anwendungsbeispiel ist aus Abb. 3 zu ersehen. Die Bauteile T1 und T2 werden hierbei mittels Bolzen B und dem beschriebenen Ring gegeneinander verspannt.. Wird hierbei Aar besehriabene Wellenring mit federndem Ring beim Sisbss bis ü-g *A -ing-Srüekt (eieae Bild 2) .· so stellt sieh Ale axial« VorSpannkraft V^ ein. Bin« Dehnung des Bolzens oder d«r Bauteil· T* und T2 um den Betrag -ds bewirkt dann nur eine Vorspannkraftändexung um ~ AP, d.h. die Vor Spannkraft Pft verändert »loh hierbei nur geringfügig.The innovation is that known self-locking tension ring constructions are combined with an axially resilient part. This part is preferably designed as a resilient conical ring, which acts like a disc spring for itself and represents a unit with the actual locking ring. In Fig. 1, a self-locking clamping ring is shown in a structural unit with the resilient ring described. By appropriately designing the resilient conical ring, a favorable spring force P spring deflection s behavior can be achieved, as is already known from disc springs and is shown in principle in Fig. 2. The installation and assembly of the innovation described is carried out in the same way as with conventional self-locking clamping rings. An application example can be seen in Fig. 3. The components T1 and T2 are in this case by means of bolts B and braced against each other the ring described .. If this Aar besehriabene shaft ring having a resilient ring when Sisbss to u-g * A -ing Srüekt (eieae Figure 2). · So provides check Ale axially «Pre-tensioning force V ^ a. If the bolt or component is stretched T * and T2 by the amount -ds then only changes the prestressing force by ~ AP, ie the prestressing force P ft changes only slightly.
