Description

Die Erfindung betrifft eine Einrichtung zur Sicherung der Befestigungsmutter an der Schlagradnabe und zum gleichzeitigen Schutz derselben gegen Verschleiß und Beschädigung.The invention relates to a device for securing the fastening nut on the impact wheel hub and to protect the same against wear and tear at the same time Damage.

Bekannt ist, neben den normalen Sicherungseinrichtungen zum Schutz des Wellenendes und des Befestigungsmittels die Mutter selbst als Schutzhaube auszubilden. Um dabei einen wirksamen Schutz zu erreichen, muß die Haube Abmessungen aufweisen, die ihre Betätigung als -Mutter erschweren.Is known, in addition to the normal safety devices for protection of the shaft end and the fastening means, the nut itself is designed as a protective cover. In order to achieve effective protection, the hood must have dimensions which complicate their activity as a mother.

Nach der Erfindung werden die Ziele Schutz und Sicherung in einfacher Weise dadurch erreicht, daß eine Haube, deren Rand als Doppelflansch ausgebildet und in deren innerem Mittelfeld Sicherungsflächen vorhanden sind, nach dem Festziehen einer normalen Befestigungsmutter über diese gesteckt wird, so daß die Sicherungsflächen an beliebigen Flächen der Mutter anliegen. Die Haube selbst wird dann durch wenigstens zwei in der Schlagradnabe oder der Schlagradscheibe eingeschraubte Schrauben gehalten, die durch die jeweils passenden, am Umfang des inneren Hauhenflansc'hes in größerer Anzahl vorhandenen Aussparungen hindurchgesteckt sind und durch den äußeren Haubenflansch abgedeckt werden. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.According to the invention, the objects of protection and security become easier Way achieved in that a hood, the edge of which is designed as a double flange and in the inner center of which there are locking surfaces after tightening a normal fastening nut is pushed over this, so that the locking surfaces rest on any surface of the nut. The hood itself is then through at least two screws screwed into the impact wheel hub or the impact wheel disc are held, the larger ones on the circumference of the inner raised flange Number of existing recesses are pushed through and through the outer hood flange to be covered. An exemplary embodiment of the invention is shown in the drawing.

Abb. i zeigt eine Schlagradbefestigung mit der erfindungsgemäßen Schutz- und Sicherungshaube im senkrechten Längsschnitt; Abb.2 stellt die Innenseite der erfindungsgemäßen Einrichtung dar.Fig. I shows an impact wheel attachment with the protective device according to the invention and safety hood in vertical longitudinal section; Fig.2 represents the inside of the device according to the invention.

Die Schlagradnabe i sitzt auf dem konischen Teil 2 der Nlühlenwelle 3 und wird durch die Mutter 4 festgehalten. Um eine Beschädigung und selbsttätiges Lösen der Mutter 4 zu verhindern, greift die Haube 5 mit ihren Sicherungsflächen 6 um die Mutter. Der Rand der Haube 5 ist als Doppelflansch 7, 8 ausgebildet, wobei der Innenflansch auf seinem Umfang verteilt angeordnete Aussparungen 9 aufweist, in die vorteilhaft zwei sich gegenüberliegende Schrauben io eingreifen, mittels deren die Haube 5 an vier Schlagradscheibe befestigt ist, was infolge der Vielzahl der Aussparungen 9 in vielen von der Stellung der Mutter 4 abhängigen Haubenstellungen möglich ist. Die Haubenaußenfläche kann in beliebiger Weise ausgebildet sein.The impact wheel hub i sits on the conical part 2 of the Nlühlenwelle 3 and is held in place by nut 4. To damage and self-acting To prevent loosening of the nut 4, the hood 5 engages with its locking surfaces 6 about the mother. The edge of the hood 5 is designed as a double flange 7, 8, wherein the inner flange has recesses 9 distributed around its circumference, into which two opposing screws intervene io, by means of whose hood 5 is attached to four impact wheel, which is due to the large number the recesses 9 in many hood positions dependent on the position of the nut 4 is possible. The hood outer surface can be designed in any way.
