Description
Palier à roulement Les paliers à roulement demandent très peu de lubrifiant ; il est cependant nécessaire de renouveler ce lubrifiant après une période d'un à deux ans en général.
Le but de cette invention est de permettre d'assurer la lubrification des paliers à roule ment pour un nombre d'années plus grand.
Le palier à roulement, objet de l'invention, comprend un dispositif interne de lubrification ; il est caractérisé en ce que ce dispositif com porte un corps de rotation en métal poreux, saturé d'huile, qu'on intercale entre chaque élément rotatif de sustentation.
Deux formes d'exécution de l'objet de l'in vention sont représentées, à titre d'exemples, sur le dessin annexé. La fig. 1 est une coupe transversale d'un roulement à rouleaux.
La fig. 2 est une coupe semblable d'un rou lement à billes.
Le roulement à rouleaux de la fig. 1 com prend un dispositif interne de lubrification constitué par des rouleaux 4 en matière po reuse et saturée d'huile, dont le nombre est égal à celui des rouleaux 3 de sustentation. Les rouleaux 4 ont un diamètre inférieur de 0,02 à 0,03 mm à celui des rouleaux 3 entre lesquels ils sont intercalés. La matière poreuse dont sont faits les rouleaux 4 peut être du bronze. Les bagues 1 et 2 du roulement sont ana logues aux bagues usuelles.
La fig. 2 représente un roulement à billes dans lequel la cage à billes 4' est en matière poreuse, saturée d'huile, et constitue ainsi le dispositif interne de lubrification. Les bagues 1 et 2 ainsi que les billes 3 sont analogues à celles des roulements à billes usuels.
Dans un roulement à aiguilles, on pourrait à volonté intercaler autant d'aiguilles en ma tière poreuse qu'il y a d'aiguilles porteuses, comme dans le roulement de la fig. 1, ou utili ser une cage à aiguilles en matière poreuse sa turée d'huile. De même, les rouleaux 4 pour raient être remplacés par une cage.
Un palier à roulement tel que ceux décrits ci-dessus ne demandera pour ainsi dire aucun entretien, surtout s'il est fermé.
Roller bearing Roller bearings require very little lubricant; it is however necessary to renew this lubricant after a period of one to two years in general.
The object of this invention is to make it possible to ensure the lubrication of rolling bearings for a greater number of years.
The rolling bearing, object of the invention, comprises an internal lubrication device; it is characterized in that this device com carries a porous metal rotating body, saturated with oil, which is interposed between each rotary supporting element.
Two embodiments of the object of the invention are shown, by way of example, in the accompanying drawing. Fig. 1 is a cross section of a roller bearing.
Fig. 2 is a similar cross section of a ball bearing.
The roller bearing of fig. 1 com takes an internal lubrication device consisting of rollers 4 made of porous material and saturated with oil, the number of which is equal to that of the lift rollers 3. The rollers 4 have a smaller diameter of 0.02 to 0.03 mm than that of the rollers 3 between which they are interposed. The porous material from which the rollers 4 are made can be bronze. The rings 1 and 2 of the bearing are analogous to the usual rings.
Fig. 2 shows a ball bearing in which the ball cage 4 'is made of a porous material, saturated with oil, and thus constitutes the internal lubrication device. The rings 1 and 2 as well as the balls 3 are analogous to those of conventional ball bearings.
In a needle bearing, one could at will insert as many porous needles as there are carrier needles, as in the bearing of FIG. 1, or use a needle cage made of porous material with its oil turée. Likewise, the rollers 4 could be replaced by a cage.
A rolling bearing such as those described above will require virtually no maintenance, especially if it is closed.
