Description
Die Rücklaufhemmung gemäß der Erfindung soll die Sperrklinken an Rücklaufgesperren ersetzen. Die bisher bekannten Gesperre, bei denen die Sperrung durch Kugeln bewirkt wird, sind mehr oder weniger verwickelt gebaut. Das Gesperre gemäß der Erfindung ist mit dem Kugellager der zu hemmenden Achse auf einfache Weise verbunden.The backstop according to the invention is intended to replace the pawls on backstops. The previously known locking mechanism, in which the locking is effected by balls are more or less intricately built. The locking mechanism according to the invention is connected to the ball bearing of the axle to be blocked in a simple manner.
Das Wesen der Erfindung besteht darin, daß die Kugeln des Lagers beim Rückwärtsdrehen der Kugeln mittels eines an dem beweglichen Teil des Lagers vorgesehenen Stiftes durch ihre Schwere in eine an dem feststehenden Teil des Lagers angeordnete keilartige Vertiefung einfallen und sperrend wirken.The essence of the invention is that the balls of the bearing when rotating backwards of the balls by means of a pin provided on the moving part of the bearing through their Heaviness fall into a wedge-like recess arranged on the fixed part of the bearing and have a blocking effect.
Die Zeichnung veranschaulicht den Gegenstand der Erfindung. Fig. ι ist ein Querschnitt durch eine Rücklaufhemmung für umlaufende Achsen; Fig. 2 ist' ein Längsschnitt dazu; Fig. 3 ein Querschnitt durch eine Rücklaufhemmung für feste Achsen und Fig. 4 ein Längsschnitt dazu.The drawing illustrates the subject matter of the invention. Fig. Ι is a cross section through a return inhibition for rotating axes; Fig. 2 is a longitudinal section thereof; Fig. 3 a cross section through a backstop for fixed axles and FIG. 4 is a longitudinal section to.
Der Spannring δ gemäß Fig. 1 und 2, der fest auf der Achse α sitzt, trägt den Stift f, welcher die Kugeln i zwischen dem Spannring b und dem Laufring c beim Umlauf der Achse a mitnimmt. Im Laufring c, der im Lager feststeht, befindet sich die keilartige Vertiefung k. Beim Umlauf der Achse α in der Richtung des Pfeiles werden die Kugeln i von dem Stift f über die Vertiefung k hinweggeschoben, wobei eine jede Kugel in diese hineinfällt, von der nachfolgenden jedoch wieder hinausgedrängt wird. Beim Rückwärtslauf dagegen wird die in der Vertiefung befindliche Kugel von den anderen an den steilen Wandteil der Vertiefung k gedrückt und so der Rücklauf der Achse α gehemmt.The clamping ring δ according to FIGS. 1 and 2, which sits firmly on the axis α , carries the pin f, which carries the balls i between the clamping ring b and the raceway c as the axis a rotates. The wedge-like recess k is located in the race c, which is fixed in the bearing. When the axis α rotates in the direction of the arrow, the balls i are pushed by the pin f over the recess k , each ball falling into it, but being pushed out again by the next one. When running backwards, on the other hand, the ball located in the recess is pressed by the others against the steep wall part of the recess k and the return of the axis α is thus inhibited.
Bei der Ausführungsfprm des Gesperres gemäß Fig. 3 und 4 spielt sich derselbe Vorgang ab mit dem Unterschied, daß hier die feststehende Achse oder der Spannring die keilartige Vertiefung k trägt, und der zwischen die Kugeln greifende Stift f am Laufring befestigt ist.In the embodiment of the locking mechanism according to FIGS. 3 and 4, the same process takes place with the difference that here the fixed axis or the clamping ring carries the wedge-like recess k , and the pin f, which engages between the balls, is attached to the raceway.
