Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Federnprüfungsmaschine, bei welcher die Feder unter schwingender Belastung genau so geprüft wird, wie sie im praktischen Betriebe beansprucht ist.The present invention relates to a spring testing machine in which the spring under vibrating load is checked exactly as it is claimed in practical operation is.
Bei allen bisher bekannten Prüfungsmaschinen wurde die Feder in kinematischer Umkehr ihrer Verwendungslage, d. h. mit der Wölbung nach oben gerichtet, geprüft. Hierdurch entstand der Nachteil, daß das Eigengewicht der Feder, insbesondere bei längeren Federn (z. B. 2 m langen Personenwagenfedern) eine meßbare Verringerung der Pfeilhöhe ,verursachte, die zu Meinungsverschiedenheiten und sogar r zu. rechtlichen Auseinandersetzungen vielfach Anlaß gab.In all previously known testing machines, the spring was tested in a kinematic reversal of its position of use, ie with the curvature pointing upwards. This gave rise to the disadvantage that the dead weight of the spring, especially in the case of longer springs (e.g. 2 m long passenger car springs), caused a measurable reduction in the height of the arrow, which led to disagreements and even r to. legal disputes were often the cause.
Die neue Anordnung vorliegender Erfindung vermeidet diesen Nachteil, indem sie den mittleren schwersten Teil der Feder unmittelbar durch die Belastungsvorrichtung (in gleicher Weise wie durch den Achslagerkasten im Betriebe) unterstützt.The novel arrangement of the present invention avoids this disadvantage by the middle heaviest part of the spring directly through the loading device (in the same way as by the axle box in the company).
Außerdem hat die neue Anordnung den Vorteil, daß die Belastungs- und Meßvorrichtungen übersichtlich und leicht zugänglich sind.In addition, the new arrangement has the advantage that the loading and measuring devices are clear and easily accessible.
Die Bedienung der Maschine ist den bisher bekannten Bedienungsweisen gegenüber insofern vereinfacht, als die zu prüfende Feder von dem betreffenden Arbeiter in stabilem Gleichgewicht an die Maschine herangebracht wird und nicht, wie bisher, beim An- und Aufbringen zur Maschine in einer zum Kippen neigenden Lage sich befindet.The operation of the machine is in comparison to the previously known modes of operation simplified than the spring to be tested by the worker concerned in stable Balance is brought to the machine and not, as before, when approaching and Applying to the machine is in a position that tends to tilt.
In Fig. ι ist die Federnprüfungsmaschine im Längsschnitt mit eingelegter Feder dargestellt, während Fig. 2 einen Querschnitt zeigt.In Fig. Ι the spring testing machine is shown in longitudinal section with an inserted spring, while Fig. 2 shows a cross section.
Die zu prüfende Feder ist mit dem Krümmungsradius nach oben an einem Rahmen a gelagert, dessen Gewicht durch Gegengewichte b und bx ausgeglichen wird, welche auch gleichzeitig den Rahmen α gegen die Meß vorrichtung c, die in der Zeichnung als Wage angegeben ist, drückt. Die Belastungsvorrichtung d ist auf dem Rahmen der Meß vorrichtung c gelagert und beansprucht dadurch sehr geringe Bauhöhe.The spring to be tested is mounted with the radius of curvature upwards on a frame a , the weight of which is balanced by counterweights b and b x , which also presses the frame α against the measuring device c, which is indicated in the drawing as a balance. The loading device d is mounted on the frame of the measuring device c and thus requires a very low overall height.
