Description
Geschlagene oder gewalzte Kegeltopf-Reibungsfeder. Gegenstand der Erfindung ist eine geschlagene oder gewalzte Kegeltopf-Reibungsfieder, insbesondere für Puffer, durch die sowohl ein sanfter Anhub ohne besondere Vorspannfeder als auch ein beliebig großer Stößelhub erzielt wird. Es sind bereits aus Blech sebgxnentförmig gestanzte, kegelig gewickelte Federn bekannt, deren Herstellung sich jedoch durch den beim Ausstanzen entstehenden großen Materialverlust erheblich verteuert. Außerdem. wird bei jenen Federn wegen der gleichen Wandstärke das Material im kleinen Federdurchmesser erheblich mehr beansprucht als im großen. Demgegenüber soll beim Erfindungsgegenstande sowohl eine gleichmäßige Materialbeanspruchung der Federn beim Zusammenbiegen als auch eine stets radial verlaufende Längsfaserrichtung erreicht werden. Dies geschieht dadurch, daß jede Wandstärke des trapezförmigen Querschnittes in gleichem Verhältnis zum dazugehörigen Radius steht, wodurch gewissermaßen ein Körper von gleicher Festigkeit entsteht.Beaten or rolled cone cup friction spring. Subject of Invention is a beaten or rolled cone pot friction feather, in particular for buffers, through which both a gentle lift without a special preload spring as an arbitrarily large ram stroke can also be achieved. They are already sebgxnent-shaped from sheet metal punched, conically coiled springs known, but their production is by significantly increases the cost of the large loss of material that occurs during the punching process. Aside from that. For those springs, the material in the small spring diameter is due to the same wall thickness considerably more stressed than on a large scale. In contrast, the subject matter of the invention both a uniform material stress on the springs when they are bent together and a longitudinal fiber direction that always runs radially can also be achieved. this happens in that each wall thickness of the trapezoidal cross-section has the same ratio stands for the associated radius, which in a sense creates a body of equal strength arises.
In der Zeichnung ist die neue Feder mit normalem Stößelhub, in einen Puffer eingebaut, im Schnitt dargestellt.In the drawing, the new spring with a normal slide stroke is in one Built-in buffer, shown in section.
Die Grundplatte mit den Vorspannschrauben a sowie das Gehäuse b und der Stößel c sind in ähnlicher Ausführung bereits bekannt. Die vorderen Federn f2 haben eine geringere Wandstärke als die hinteren Federn t1, wodurch ein leichteres Federn und damit ein sanfter Anhub des Stößels erreicht wird. Der zur Federsäule erforderliche Bodenringel und die Zwischenringe e2 können sowohl im Gesenk geschlagen als auch aus Stahlguß hergestellt sein. Die Zwischenringe sind zur Vergrößerung der Reibungsfläche mit einem in den Trichter der angrenzenden Feder ragenden, kegelringförmigen Ansatz e3 versehen.The base plate with the pre-tensioning screws a and the housing b and the plunger c are already known in a similar design. The front springs f2 have a smaller wall thickness than the rear springs t1, whereby a lighter spring and thus a gentle lift of the plunger is achieved. The bottom ring required for the spring column and the intermediate rings e2 can either be punched in the die or made from cast steel. To increase the friction surface, the intermediate rings are provided with a conical ring-shaped shoulder e3 protruding into the funnel of the adjacent spring.
Beine Stoß treten zunächst die schwächeren Federn f2 in Tätigkeit und bei einer gewissen Einsenkung derselben erst die stärkeren Federn/,.. Der Rückstoß des Stößels ist ebenfalls ein weicher, da der größte Teil der Stoßarbeit durch Reibung verzehrt ist.In the bump, the weaker springs f2 first come into action and with a certain depression of the same the stronger springs / ... The recoil the ram is also a softer one, since most of the impact work is done by friction is consumed.
