Description
<Desc/Clms Page number 1>
Joint d'étanchéité pour véhicules tels que cylindres de compactage du sol, ainsi que véhicule pourvu dudit joint.
La présente invention concerne un joint d'étarichéité dis- posé entre un cylindre tournant et un châssis support de cylindre dans des véhicules à cylindre destinés au compactage du sol. Dans de tels véhicules, il est souvent prévu, sur la surface frontale du cylindre ou du bandage qui l'entoure, une couronne dentée ayant une denture intérieure, avec laquelle engrène un pignon supporté dans la paroi du châssis de support du cylindre* C'est par l'inter- médiaire de ce pignon et de cette couronne dentée que le cylindre est entraîné. L'invention a pour but de réaliser un joint étanche qui protège contre la boue ou analogue de ces pièces d'entraînement ou pièces analogues.
<Desc/Clms Page number 2>
Dans ce but, l'invention est caractérisée par un anneau en une matière à faible coefficient de frottement qui est guidé dans une rainure annulaire prévue dans la face frontale du cylindre, ledit anneau étant appliqué par des moyens de pression contre la paroi du châssis de support du cylindre.
L'invention s'étend également aux caractéristiques résul- tant de la description ci-après et des dessins joints ainsi qu'à leurs combinaisons possibles. La description se rapporte à des mo- des de réalisation donnés à titre d'exemple non limitatif et expli- qué avec référence aux dessins joints dans lesquels - la fig. 1 est une coupe à travers un dispositif conforme à l'invention, - fig. 2 et 3 montrent à une échelle plus grande des détails de construction en différents endroits du pourtour.
Le bandage 10 d'un cylindre est supporté au moyen d'un flasque de palier 11 sur un arbre 12. Cet arbre 12 est supporté au moyen d'un palier 13 dans la paroi d'un châssis 14. Sur le flasque de palier # est monte une couronne dentée 15 avec une denture intérieure 16,,, par laquelle le cylindre est entraînée d'une manière qui n'est pas représentée en détail. En vue de protéger les organes d'entraînement contre l'encrassement, il est prévu un joint d'étan- chéité entre le cylindre tournant et le flasque de palier fixe 14.
Dans ce but, il est prévu, sur la face frontale de la couronne dentée 15, une gorge annulaire 17. Dans cette rainure est guidée un anneau 18 en fonte grise, bronze autolubrifiant ou de matière synthétique, déplaçable axialement. Cet anneau 18 est placé sous l'influence de ressorts 19 (Fig.2), qui sont répartis régu- lièrement sur son pourtour et qui l'appliquent contre la paroi du châssis de support de cylindre. De cette manière, la fente qui reste libre entre le cylindre ou la couronne dentée 15 et le châssis est fermée à joint étanche, ce qui s'oppose à l'introduction de boue ou analogue.
<Desc/Clms Page number 3>
Afin que l'anneau 18 tourne régulièrement avec le cylindre, il est entraîné en différents points par des broches d'entraînement 20 telles que celles représentées dans la fig. 3, et cela, cependant, de telle manière que l'application axiale contre la paroi 14 ne soit pas influencée. La gorge 17 peut avantageusement être remplie avec de la graisse. Ainsi, d'une part, l'application de l'anneau d'étan- chéité 10 contre la paroi 14 est facilitée et d'autre part, la péné- tration de l'eau et de la poussière fine dans la rainure 17 est em- pêchée..

Seal for vehicles such as soil compaction cylinders, as well as vehicles provided with said seal.
The present invention relates to a tightness seal disposed between a rotating cylinder and a cylinder support frame in cylinder vehicles intended for soil compaction. In such vehicles, there is often provided, on the front surface of the cylinder or of the tire which surrounds it, a ring gear having internal teeth, with which engages a pinion supported in the wall of the cylinder support frame * C ' The cylinder is driven by the intermediary of this pinion and this ring gear. The object of the invention is to provide a tight seal which protects against mud or the like of these drive parts or the like.
<Desc / Clms Page number 2>
For this purpose, the invention is characterized by a ring made of a material with a low coefficient of friction which is guided in an annular groove provided in the front face of the cylinder, said ring being applied by pressure means against the wall of the frame. cylinder support.
The invention also extends to the characteristics resulting from the following description and the accompanying drawings as well as to their possible combinations. The description relates to embodiments given by way of nonlimiting example and explained with reference to the accompanying drawings in which - FIG. 1 is a section through a device according to the invention, - fig. 2 and 3 show construction details on a larger scale at various locations around the area.
The tire 10 of a cylinder is supported by means of a bearing flange 11 on a shaft 12. This shaft 12 is supported by means of a bearing 13 in the wall of a frame 14. On the bearing flange # is mounted a toothed ring 15 with internal teeth 16 ,,, by which the cylinder is driven in a way which is not shown in detail. In order to protect the drive members against soiling, a seal is provided between the rotating cylinder and the fixed bearing flange 14.
For this purpose, there is provided, on the front face of the toothed ring 15, an annular groove 17. In this groove is guided a ring 18 of gray cast iron, self-lubricating bronze or of synthetic material, movable axially. This ring 18 is placed under the influence of springs 19 (FIG. 2), which are distributed evenly around its periphery and which apply it against the wall of the cylinder support frame. In this way, the gap which remains free between the cylinder or the toothed ring 15 and the frame is sealed, which opposes the introduction of sludge or the like.
<Desc / Clms Page number 3>
So that the ring 18 rotates regularly with the cylinder, it is driven at different points by drive pins 20 such as those shown in FIG. 3, and this, however, in such a way that the axial application against the wall 14 is not influenced. The groove 17 can advantageously be filled with grease. Thus, on the one hand, the application of the sealing ring 10 against the wall 14 is facilitated and, on the other hand, the penetration of water and fine dust into the groove 17 is. prevented ..
