Description

a- ' "Nut-Keilverbindung" Die Erfindung betrifft eine Nut-Keilverbtndung für Nuten mit zueinander parallelen Seitenflächen, bei welcher das als Keil wirkende Teil federnd ist. Oft ist es nicht möglich, bei einer Nut-Keilverbindung die Lage der Nut an den einen Hauteil und clie jenige des Keils rav dem anderen Bauteil Ho genau dinanfar zuzuordnen, daß bei® 2usamenfÜgen der beiden Bauteile entlang einer' starren fühw rang. das Keilprofil genau mittig in das Nutprofil trifft. Die Anforderungen an Genauigkeit der gegenseitigen-Lagezuordnung von Nut und Keil können zwar dadurch verringert werden, das der Keil bzw. das als Keil wirkende Teil als federndes Teil ausgeführt wird, welches .auf Grund snUnor Elastizität Abvj!zsi- chungen von der genau gegenüberliegenden Lage von Nut .und Keil auszugleichen vermag. Jedoch bleibt n3 auch bei Verwendung ,@cä eher federnder Keileallerein@:@.?:;sa notwendig, beim Zu- . samranfügen der Bnateile entlang wi:@3# Mauren Fifhrung den:@:i T@ durch entsprechendes Biegen in die Nut einzuführen, wenn die Lageabweichung zwischen Nut und Keil zu groß wird. .Oft ..ist . aber ein derartiges Einführen das leAernden Keils in die Nut mittels solchen Biegens deshalb unmöglich, weil dieser Keil beim Zusammenfügen der Bauteile nicht mehr zugänglich-ist. Die Aufgabe der Erfindung ist,, ein als federnder Keil wirken- des Teil so zu gestalten, daß bei Lagƒabweichungen das Ein- führen dieses Teils in die Nut ohne äußeren Eingriff, also auch im Falle einer Unzugänglichkeit nüglich ist.'Woiterhin soll das als Keil wirkende Teil so. ausgeführt sein, daß von ihm auf die beiden Seitenflächen der Nut gleich große Anpreß- kräfte ausgeübt werden. Die Erfindung-besteht darin, daß dieses Teil als eine um eine , zu den Seitenflächen der Nut parallelen Achse drchbar gelager- te, geschlitzte und unter Pressung, in die Nut paZasendo Feder- scheibe ausgebildet ist, deren kreiaföraniger Außenumfang oxzep- trisch zur Drehachse verläuft.

Wird das mit der hat 21 ver- sehene Bauteil 2 auf das Bauteil 1 entlang @eäner 'starren Füh- " rung aufgesetzt-und besteht zwischen der Mitte des Bolzens 12 und der Mitte der Nut 21 eiine Lageabweichung g, so wird diese Lageabweichung dadurch ausgeglichen, daß sich die geschlitzte Federscheibe 11 beim Auftreffen der Kante 22 der Nut 21 auf ihrem °gegentiber ihrer Bohrung exzentrischen Umfang so weit verdreht, bis diese Federscheibe unter Zusammenpressen in die Nut 21 paßt. " a- ' "Groove-spline connection" The invention relates to a groove-wedge connection for grooves with mutually parallel side surfaces, in which this is a wedge acting part is resilient. Often it is not possible to use the Location of the groove on one skin part and that of the wedge rav to assign exactly dinanfar to the other component Ho that at® 2usamenfÜgen the two components along a 'rigid guide rank. the spline meets exactly in the middle of the groove profile . the Requirements for accuracy of mutual position assignment of groove and wedge can be reduced by the the wedge or the part acting as a wedge as a resilient part is executed, which due to snUnor elasticity Abvj! zsi- the exact opposite position of the groove . and wedge able to compensate. However, n3 remains even when using , @ cä rather resilient wedges i® allerein @: @. ?:; sa necessary when accessing . join the parts along wi: @ 3 # Moors leadership : @: i T @ to be introduced into the groove by appropriate bending if the Deviation in position between groove and wedge becomes too great . .Often .. is . but such insertion of the draining wedge into the groove impossible by means of such bending because of this wedge is no longer accessible when assembling the components. The object of the invention is, a acting as a resilient wedge- of the part in such a way that, in the event of positional deviations, the lead this part into the groove without external intervention, so is also sufficient in the case of inaccessibility should the part acting as a wedge be like this. be carried out that of equal pressure on the two side surfaces of the groove forces are exercised. The invention consists in the fact that this part as one around one , the axis parallel to the side surfaces of the groove can be te, slotted and under pressure, into the groove paZasendo spring disc is formed, the Kreiaföraniger outer circumference oxzep- tric to the axis of rotation. In the drawing, a groove / cellar connection is shown by the Erfh) - application shown schematically.
