Abstract

The subject of the present invention is a self-lubricating roller 5 mounted rotationally on a spindle 1 with interposition of a self-lubricating cloth 6. According to the invention, the cloth 6 is fixed to the spindle 1.

Description

Les galets sont couramment utilisés en mécanique notamment dans l'aéronautique, car ils permettent de supporter de fortes charges radiales statiques ou dynamiques. Ces galets sont montés sur leur axe soit par I'intermdiaire d'un roulement à rouleaux ou a aiguilles, soit avec interposition d'un tissu lubrifiant.Rollers are commonly used in mechanics, especially in aeronautics, because they allow to support strong static or dynamic radial loads. These rollers are mounted on their axis either by means of a roller or needle bearing, or with the interposition of a lubricating cloth.

Dans les galets autolubrifiants actuellement réalisés, le tissu autolubrifiant est collé a l'intérieur du galet de sorte qu'il tourne en meme temps que celui-ci; cette disposition est en effet considérée comme la seule utilisable.In the self-lubricating rollers currently produced, the self-lubricating fabric is glued to the inside of the roller so that it rotates at the same time as the latter; this provision is in fact considered as the only usable one.

Or, la demanderesse a constaté que si le tissu était fixé non au galet mais a l'axe de celui-ci, l'endurance sous charge était accrue de manière surprenante, pratiquement doublée.However, the Applicant has found that if the fabric was attached not to the roller but to the axis thereof, the endurance under load was surprisingly increased, practically doubled.

La présente invention a en conséquence pour objet un galet autolubrifiant monté à rotation sur un axe avec interposition d'un tissu autolubrifiant, caractérisé en ce que le tissu est fixé sur l'axe.The present invention therefore relates to a self-lubricating roller rotatably mounted on an axis with the interposition of a self-lubricating fabric, characterized in that the fabric is fixed on the axis.

Le tissu reste donc immobile lors de la rotation du galet.The fabric therefore remains stationary during the rotation of the roller.

On a décrit ci-après, à titre d'exemples non limitatifs, deux modes de réalisation du galet selon l':nvention, avec référence au dessin annexé dans lequel
La Figure 1 est une vue en coupe axiale d'un
premier mode de réalisation,
La Figure 2 est une vue en coupe axiale
d'un second mode de réalisation.We have described below, by way of nonlimiting examples, two embodiments of the roller according to the: nvention, with reference to the accompanying drawing in which
Figure 1 is an axial sectional view of a
first embodiment,
Figure 2 is an axial sectional view
of a second embodiment.

A la Figure 1, on voit un axe 1 qui comporte une collerette la à une certaine distance de son extrémité. Une vis 2 maintient contre cette collerette deux rondelles 3 et 4 enserrant un galet 5. Un tissu autolubrifiant 6 collé sur l'axe 1 est interposé entre d'une part le galet et d'autre part l'axe et les rondelles.In Figure 1, we see an axis 1 which has a flange at a certain distance from its end. A screw 2 maintains against this flange two washers 3 and 4 enclosing a roller 5. A self-lubricating fabric 6 bonded to the axis 1 is interposed between on the one hand the roller and on the other hand the axis and the washers.

Dans le mode de réalisation de la Figure 2, une bague 7 est montée à rotation sur un axe 8 entre deux rondelles fixes 9a et 9b, un tissu autolubrifiant 10 collé sur l'axe 8 étant interposé entre cet axe et la bague 7. Une deuxième bague 11 est montée a rotation sur la bague 7 avec interposition d'un tissu autolubrifiant 12 collé dans l'alésage de la bague. Des éléments 13a et 13b en tissu lubrifiant sont également interposés entre d'une part les bagues 7 et 11 et d'autre part les rondelles 9a et 9b. Ce mode de réalisation présente une sécurité de fonctionnement particulièrement grande. In the embodiment of Figure 2, a ring 7 is rotatably mounted on an axis 8 between two fixed washers 9a and 9b, a self-lubricating fabric 10 bonded to the axis 8 being interposed between this axis and the ring 7. A second ring 11 is rotatably mounted on ring 7 with the interposition of a self-lubricating fabric 12 bonded in the bore of the ring. Elements 13a and 13b in lubricating fabric are also interposed between on the one hand the rings 7 and 11 and on the other hand the washers 9a and 9b. This embodiment has a particularly high operating safety.

I1 va de soi que la présente invention ne doit pas être considérée comme limitée aux modes de réalisation décrits et représentés, mais en couvre, au contraire, toutes les variantes.  It goes without saying that the present invention should not be considered as limited to the embodiments described and shown, but on the contrary covers all variants thereof.
