Description
Die Erfindung bezieht sich auf Klemmrollenschaltwerke. The invention relates to clamping roller switchgear.
Erfindungsgemäß besteht die Schalteinrichtung aus einer fest auf der getriebenen Welle sitzenden Scheibe o. dgl., die von einem Schaltring umfaßt wird, der von einer Schuboder Zugstange hin und her bewegt wird.According to the invention, the switching device consists of a fixed on the driven shaft seated disc o. The like., Which is covered by a switching ring, which is of a push or Pull rod is moved back and forth.
Zwischen Schaltring und Schaltscheibe sind Klemmrollenpaare untergebracht, von welchen je eine Rolle drehbar in einer Ausnehmung der Schaltscheibe ruht, während die andere Rolle mit etwas Spiel so gelagert ist, daß sie sich zwischen dem Schaltring und der ersten Rolle festklemmen kann.Between the switching ring and the switching disc there are pairs of clamping rollers, from each of which a role rotatably rests in a recess of the switching disc, while the other role with some play is mounted so that it is between the switching ring and the first roll can clamp.
Die Verbindungslinie zwischen dem Rollenanlagepunkt am Ring und der Mitte der Klemmrolle bildet mit der Verbindungslinie, der beiden Rollenmitten einen in der Wirkung einem Kniehebel gleichkommenden stumpfen Winkel.The connecting line between the roller contact point on the ring and the center the pinch roller forms with the connecting line, the two roller centers one in the Effect of obtuse angle equivalent to a toggle lever.
Dadurch werden einige bei den bekannten Klemmrollenübertragungen eintretenden Nachteile vermieden.As a result, some will occur with the known pinch roller transmissions Avoid disadvantages.
Bei den bekannten Klemmrollengetrieben wird jede Klemmrolle immer an die gleiche Stelle der Keilfläche stoßförmig gepreßt, und da die Auflagestelle nur längs einer Linie erfolgt, tritt hier auch beim besten Material eine starke Abnutzung ein, welche zu muldenförmigen Bildungen führt, wodurch der Klemmwinkel sich ändert, ein Gleiten der Rollen eintritt und zuletzt die Welle nicht mehr mitgenommen wird.In the known pinch roller drives, each pinch roller is always connected to the same Point of the wedge surface pressed in a jerk-shaped manner, and there the support point only along a line occurs, even with the best material there is heavy wear, which becomes trough-shaped Formations, whereby the clamping angle changes, leads to a sliding of the Roll occurs and finally the wave is no longer taken.
Beim Gegenstand der vorliegenden Erfmdung bildet die Auflagestelle nicht eine Linie, sondern durch die zweite Rolle eine Fläche, die größer als der halbe Umfang der Rolle ist. Die eigentliche Klemmrolle wiederum ändert dauernd am Schaltring ihre Auflagestelle, und weil sie beim Hinundhergehen auch sich immer etwas dreht, so ändert sie auch ihre Auflagestelle gegenüber der zweiten Rolle, welche ebenfalls die kleinen Drehungen mitmacht.In the subject matter of the present invention, the support point does not form a line, but through the second roll an area that is larger than half the circumference of the roll is. The actual pinch roller, in turn, constantly changes its contact point on the switching ring, and because it always rotates a little when going back and forth, it also changes its point of support in relation to the second Role, which also makes the small turns.
Diese Klemmrollenanordnung bietet somit eine sichere Gewähr gegen schnelle Abnutzung. This clamping roller arrangement thus offers a reliable guarantee against rapid wear.
Auf der Zeichnung ist ein Ausführungsbeispiel in den Abb. 1 und 2 veranschaulicht. In the drawing, an exemplary embodiment is illustrated in FIGS. 1 and 2.
Diese zeigen die Klemmrollenübertragung in zwei zueinander senkrechten Schnitten mit teilweiser Ansicht.These show the pinch roller transfer in two mutually perpendicular sections partial view.
Die die Übertragung bewirkenden Klemmrollen α wälzen sich an Gegenrollen b ab, die leicht drehbar in einer auf die anzutreibende Welle c aufgesetzten Scheibe d o. dgl. gelagert sind. ;The pinch rollers α effecting the transmission roll on counter-rollers b , which are easily rotatable in a disk d or the like mounted on the shaft c to be driven. ;
Der Eingriff zwischen den Klemmrollen a und den Gegenrollen b sowie mit dem lose um die Klemmrollen α gelegten Antriebsring e wird durch in die Scheibe d eingesetzte Schraubenfedern / o. dgl. gesichert.The engagement between the pinch rollers a and the counter rollers b and with the drive ring e loosely placed around the pinch rollers α is secured by helical springs / or the like inserted into the disk d.
Die Klemmrollen α sind ferner mittels Zapfen a·1 in die Scheibe d seitlich umschließenden Führungsscheiben g eingesetzt.The pinch rollers α are also inserted by means of pins a · 1 into the guide disks g laterally surrounding the disk d.
Der Antriebsring e ist durch die Führungsscheiben g übergreifende Stege Ii, die durch Schrauben i o. dgl. befestigt sind, geführt.The drive ring e is guided through webs Ii which cross guide disks g and which are fastened by screws i or the like.
