Abstract

Adjustable ball joint for press ram comprises a ball (2) mounted between two parts which are movable towards each other, the cup (3) and cup race (4), at least one of which is centred only on the ball. Pref. the cup is stationary and the ball is fixed in posn. while the cup race centres itself only on the ball and is capable of adjustment after centering. The cup race pref. consists of a race (4) having good slip properties and a race (5) having good strength properties.

Description

Kugelgelenk für Pressenstößel Die Erfindung befaßt sich mit einem nachstellbaren Kugelgelenk, besonders an Pressenstößeln.Ball joint for press ram The invention is concerned with a adjustable ball joint, especially on press rams.

Es ist bekannt, Pressenstößel und Pleuel mit Hilfe von Kugelgelenken zu verbinden. Diese Kugelgelenke übertragen die gesamte Preskraft und sind deshalb besonders bei schnellaufenden Präzisions-Stanzautomaten hoch beansprucht. Während man früher die Kugelkalotten direkt im den Gußkörper des Stößels und den Kalottenring in die Mutter einarbeitete, ging man später wegen der höher werdenden Gleitgeschwindigkeit zur Lagerung der Kugel in Bronze über, wobei der Bronzering in die Mutter eingelassen wurde. Solche Lagerungen haben den Nachteil, daß bei einem durch die Schlagbeanspruchungen oder das Nachstellen der Mutter auftretenden Versatz zwischen der Kalotte und dem Kalottenring diese nicht mehr auf der vollen Kalotten- oder Kalottenringfläche tragen. Dadurch neigt besonders der Kalottenring zum Fressen an der Kugel.It is known to press rams and connecting rods with the help of ball joints connect to. These ball joints transmit the entire pressing force and are therefore Particularly highly stressed with high-speed precision stamping presses. While one used earlier the spherical caps directly in the cast body of the plunger and the spherical cap ring worked into the mother, one went later because of the increasing sliding speed to store the ball in bronze over, with the bronze ring embedded in the nut became. Such bearings have the disadvantage that one by the impact stresses or readjusting the nut occurring offset between the dome and the Calottes ring no longer wear these on the full calotte or calotte ring surface. As a result, the dome ring in particular has a tendency to seize on the ball.

Die Erfindung behebt diesen Nachteil, indem die Kugel zwischen zwei aufeinander zustellbaren Lagerteilen, der Kalotte und dem Kalottenring gelagert ist, wobei mindestens eines dieser Lagerteile nur an der Kugel zentriert ist Tritt nun in der unteren Kalotte durch Schlagbeanspruchung ein Versatz auf, so versetzt sich entweder die Kugel und zentriert den Kalottenring in ihrer neuen Lage, oder die Kalotte verschiebt sich in die vom Kalottenring bestimmte Lage. Ebenso führt es nicht zu einseitiger Auflage wenn die Mutter zum Nachstellen verdreht wird und nicht zur Kugel zentrisch läuft. Dadurch ist eine satte Auflage sowohl auf der ganzen Kalottenfläche, als auch auf der ganzen Kalottenringfläche gewährleistet.The invention overcomes this disadvantage by placing the ball between two stackable bearing parts, the spherical cap and the spherical ring are stored is, at least one of these bearing parts is only centered on the ball step now there is an offset in the lower dome due to impact stress, so offset either the ball and centers the dome ring in its new position, or the dome moves into the position determined by the dome ring. Likewise leads there is no one-sided support when the nut is turned to readjust and does not run centrically to the ball. This is a full edition both on the whole Calotte surface, as well as on the entire calotte ring surface guaranteed.

Ein Konstruktionsbeispiel ist durch die Abbildung dargestellt.A construction example is shown in the figure.

Eine Spindel 1 stützt sich ab auf der Kalotte 3 und ist gegen Herausheben nach oben gesichert durch den Kalottenring 4, der fest mit einem Verstärkungsring 5 verbunden ist. Der Kalottenring 4 mit Verstärkungsring 5 zentriert sich auf der Kugel 2. Mit Hilfe der Mutter 6 kann das Spiel der Kugel 2 zwischen der Kalotte 3 und dem Kalottenring 4 eingestellt werden. Die Kugel lagerung ist untergebracht in dem ein- oder mehrteiligen Stößel 7.A spindle 1 is supported on the spherical cap 3 and is against being lifted out secured upwards by the spherical ring 4, which is fixed with a reinforcing ring 5 is connected. The spherical ring 4 with reinforcing ring 5 is centered on the Ball 2. With the help of the nut 6, the game of the ball 2 between the dome 3 and the dome ring 4 can be adjusted. The ball bearing is housed in the one-part or multi-part plunger 7.
