Description

Zweck der vorliegenden Erfindung ist die Verminderung des Verschleißes der Gelenkbolzen und der Kettengliederaugen einer Gliederlaufkette für Kraftfahrzeuge in Verbindung mit einer Verminderung des Kraftaufwandes und die Erzielung eines geräuschlosen Laufes der Kette.The purpose of the present invention is to reduce wear on the pivot pins and the chain link eyes of a link chain for motor vehicles with a reduction of the effort and the achievement of a noiseless running of the chain.

Die bisher bekannt gewordenen Versuche, zu diesem Zweck geschmierte Gleitlager zu verwenden, scheitern an dem. Nachteil, daß das Schmiermittel bei den kurzen hin und her gehenden Bewegungen des Gelenkbolzens bald verbraucht ist. Es dringt, da die gesamte Kette stets unter Spannung steht, also auch die Lagerstelle zwischen Gelenkbolzen und Gliedauge nicht entlastet wird, kein Schmiermittel an die eigentliche Lagerstelle nach, so daß nach kurzer Betriebszeit der Zustand einer trockenen Lagerung erreicht ist.The previously known attempts to use lubricated plain bearings for this purpose use, fail at that. Disadvantage that the lubricant in the short back and forth forthcoming movements of the hinge pin is soon used up. It penetrates as the whole The chain is always under tension, including the bearing point between the hinge pins and limb eye is not relieved, no lubricant to the actual bearing point so that after a short period of operation the state of dry storage is achieved.

Dieser Nachteil wird durch das Wälzoder Nadellager behoben, bei dem sich auch bei kleinen Drehbewegungen des Gelenkbolzens die Walzen oder Nadeln abrollen und das Schmiermittel stets zwischen den Walzen und der Walzenbahn nachdringt.This disadvantage is remedied by the roller or needle roller bearing, which also has unroll the rollers or needles in the event of small rotary movements of the hinge pin and the lubricant always penetrates between the rollers and the roller track.

• Der Erfindungsgegenstand ist auf der Zeichnung in teilweise geschnittener Draufsicht dargestellt.• The subject of the invention is shown in the drawing in a partially sectioned plan view shown.

Die Kettenglieder sind mit α und die deren Augen a1, a- verbindenden Bolzen mit b bezeichnet. Die Walzen oder Nadeln, c in den Augen a, a1 der Kettenglieder sind mit ihren Enden in Ringen c1 gelagert. Die Dichtungen sind mit d1, d2 bezeichnet. Der Ring d1 sitzt im Auge α1 und der Ring d? auf dem Zapfen b fest, e ist ein Kanal und / ein Scharniernippel, durch welchen dem Wälz- oder Nadellager Schmiermaterial unter Druck zugeführt wird. Der Kanal e kann vom äußeren Ende des Lagerzapfens b ausgehen, oder er geht von der Innen- oder Außenfläche des Kettengliedes α, α1 und ist bis zur Mitte des Wälz- oder Nadellagers geführt, so daß, wenn aus einer auf den Nippel f gesetzten Druckvorrichtung Schmiermaterial durch den Kanal e bis zum 4S Wälz- oder Nadellager c gedrückt wird, dasselbe die Dichtungen d1, d2 passiert, um so zu verhindern, daß Staub- oder sonstige Schmutzteilchen durch die Dichtungen nach den Wälz- oder Nadellagern gelangen können 5<> bzw. etwa eingetretener Staub oder anderer Schmutz von dem Schmiermaterial durch die Dichtungen' hindurch nach außen gedrückt wird.The chain links are denoted by α and the bolts connecting their eyes a 1 , a are denoted by b. The rollers or needles, c in the eyes a, a 1 of the chain links are mounted with their ends in rings c 1. The seals are denoted by d 1 , d 2. The ring d 1 sits in the eye α 1 and the ring d? fixed on the pin b , e is a channel and / a hinge nipple through which the roller or needle roller bearing is supplied with lubricating material under pressure. The channel e can start from the outer end of the journal b , or it goes from the inner or outer surface of the chain link α, α 1 and is guided to the center of the roller or needle bearing, so that if one is placed on the nipple f Pressure device lubricating material is pressed through the channel e to the 4S roller or needle bearing c , the same passes the seals d 1 , d 2 in order to prevent dust or other dirt particles from getting through the seals to the roller or needle bearings 5 <> or any dust or other dirt that has entered is pressed outwards by the lubricating material through the seals.
