Patentirt im Deutschen Reiche vom 15. Februar 1890 ab.Patented in the German Empire on February 15, 1890.

An denjenigen Gewindeflächen an Bolzen und Mutter, welche beim Anziehen der Mutter den Druck aufnehmen, werden Sperrzähne von gleicher Gröfse eingeschnitten. Dieselben liegen senkrecht über einander, und ihre Anzahl auf einer Windung wächst mit dem Bolzendurchmesser. Die Sperrzähne der Mutter gehen beim Anschrauben anfangs an den Sperrzähnen des Bolzens vorbei, ohne dieselben zu berühren. Bei weiterem Anziehen der Mutter würden die Sperrzähne, welche den Druck aufzunehmen haben, sich gegenseitig festklemmen, wenn nicht eine elastische Unterlegscheibe dieses verhinderte. Die Sperrzähne der Mutter gleiten nun auf jenen des Bolzens hin und werden im dargestellten Falle bei jedesmaliger Drehung um einen Winkel von 60 ° von den Sperrzähnen des Bolzens festgehalten. Die Sicherung erreicht ihre Grenze, wenn die Sperrzähne der Mutter die Lücken zwischen den Bolzensperrzähnen vollständig ausfüllen und die Unterlegscheibe sich nicht weiter zusammendrücken läfst.On those threaded surfaces on the bolt and nut that are exposed when the nut is tightened to absorb the pressure, ratchet teeth of the same size are cut. The same lie perpendicular to each other, and their number on one turn increases with the bolt diameter. When screwing on, the ratchet teeth of the nut initially pass the ratchet teeth of the bolt without touching them. If the nut is tightened further, the ratchet teeth, which have to absorb the pressure, would clamp each other tightly, if not an elastic washer prevented this. The ratchet teeth of the Nut slide now on those of the bolt and are in the illustrated case with each time Rotation through an angle of 60 ° is held by the ratchet teeth of the bolt. The backup reaches its limit when the The ratchet teeth of the nut completely fill the gaps between the pin ratchet teeth and the washer cannot be compressed any further.

Soll die Verbindung gelöst werden, so ist die Unterlegscheibe zu entfernen. Um letzteres leicht ausführen zu können, kann man die Unterlegscheibe aus einem leicht zerstörbaren und elastischen Stoff herstellen; aufserdem bringe man, wenn der Schraubenkopf leicht zugänglich ist, die Unterlegscheibe unter letzterem und nicht unter der Mutter an, da hier beim Entfernen einer schwer zerstörbaren Unterlegscheibe das Bolzengewinde leicht beschädigt werden könnte, und weil aufserdem die Gesperr-Schraubenmutter höher als eine gewöhnliche Schraubenmutter ist.If the connection is to be loosened, the washer must be removed. To the latter Easy to run, the washer can be made from an easily destructible one and make elastic fabric; also bring one if the screw head is easy accessible, the washer under the latter and not under the nut, as here when removing a washer that is difficult to destroy, the bolt thread is slightly damaged and because the ratchet nut is higher than an ordinary one Screw nut is.

Claims (1)

Patent-Anspruch:Patent claim: Eine Schraubensicherung, bei welcher das unbeabsichtigte Losdrehen der Schraubenmutter dadurch verhindert ist, dafs an der Schraubenfläche des Bolzengewindes Sperrzähne angeschnitten sind, welchen andere Sperrzähne entsprechen, die sich an der mit der genannten Schraubenfläche in Berührung tretenden Fläche des Muttergewindes vorfinden.A screw locking device, in which the unintentional loosening of the screw nut this prevents ratchet teeth from being cut on the screw surface of the bolt thread are to which other ratchet teeth correspond, which come into contact on the surface that comes into contact with said helical surface of the nut thread.
