PATENTAMT.PATENT OFFICE.
Es ist bekannt, bei Maschinenteilen künstliche Bruchstellen zu schaffen, um einer Überlastung der Teile vorzubeugen. Nach vorliegender Erfindung wird der Maschinenteil aus zwei gegeneinander drehbar verbundenen Stücken zusammengesetzt, welche durch die künstliche Bruchstelle in ihrer gegenseitigen Lage gehalten werden. Tritt eine gefährliche Überlastung ein, so wird die Bruchstelle zer-It is known to create artificial break points in machine parts to prevent overload to prevent the parts. According to the present invention, the machine part is made up of two mutually rotatably connected Pieces put together, which by the artificial fracture point in their mutual Can be held. If a dangerous overload occurs, the break point will be

Hierdurch verlängert oder verkürzt sich der Maschinenteil, und die zu hohe Beanspruchung hört auf.disturbs, and the pieces that make up the machine part can be against each other turn. As a result, the machine part is lengthened or shortened, and the excessive stress stop.
ig Auf der Zeichnung ist die Anwendung der Erfindung an der Exzenterstange einer Hartzerkleinerungsmaschine dargestellt.ig The drawing shows the application of the invention to the eccentric rod of a hard crushing machine shown.
Auf der Welle α sitzt das Exzenter δ. Der Exzenterbügel c hat die gebräuchliche Gestalt und ist durch einen Bolzen d mit der Exzenterstange e verbunden, welche ihrerseits durch den Bolzen f mit den anschließenden Maschinenteilen in Verbindung steht. Die Exzenterstange β hat im wesentlichen U-förmigen Querschnitt und umgreift mit zwei Lappen den unteren Teil des Exzenterbügels c. Der Exzenterbügel ist bei g zu einer Auflagefläche ausgebildet, auf welche die Fläche h der Exzenterstange e paßt. Beide Flächen werden durch eine Schraube i zusammengehalten. Die Schraube i ist so berechnet, daß sie normaler Beanspruchung standhält. . ■The eccentric δ sits on the shaft α. The eccentric bracket c has the usual shape and is connected by a bolt d to the eccentric rod e , which in turn is connected to the adjoining machine parts by the bolt f. The eccentric rod β has an essentially U-shaped cross-section and with two tabs it encompasses the lower part of the eccentric bracket c. The eccentric yoke is formed at g to form a support surface on which the surface h of the eccentric rod e fits. Both surfaces are held together by a screw i . The screw i is calculated so that it can withstand normal stress. . ■
Wenn die Beanspruchung das zulässige Maß überschreitet, so zerreißt die Schraube i,- die Exzenterstange e dreht sich gegen den Bügel so weit, daß die Punkte a,d.\mdf in einer Graden liegen, während die Flächen g und h voneinander abklappen. Da die Summe der Entfernungen von α bis d und von d bis f größer ist als ■ die Entfernung von α bis f bei Arbeitsstellung der Teile, so gewinnt das Exzenter so viel an Länge, daß nach dem Zerreißen der Schraube i jede zu hohe Beanspruchung aufhört. In gleicher Weise kann die Erfindung auch bei einer als Druckstück wirkenden Exzenterstange Anwendung finden, mit dem Unterschied, daß alsdann beim Bruch der Sicherung nicht eine Verlängerung, sondern eine Verkürzung der Exzenterstange eintritt. ·If the load exceeds the permissible level, the screw i breaks - the eccentric rod e rotates against the bracket so far that the points a, d. \ Mdf lie in one degree, while the surfaces g and h fold away from each other. Since the sum of the distances from α to d and from d to f is greater than ■ the distance from α to f when the parts are in the working position, the eccentric gains so much length that after the screw i breaks, any excessive stress ceases . In the same way, the invention can also be used with an eccentric rod acting as a pressure piece, with the difference that when the fuse breaks, the eccentric rod is shortened rather than lengthened. ·
