Abstract

The present invention relates to a spring-mounted roller mounted in rotation on a spindle by the intermediary of a bearing. This roller is characterised in that its spindle 3 is constituted by a sleeve 4 inside of which are mounted in an axially sliding manner two joining pieces 5, 6, pushed towards the outside by a compression spring 7 disposed between them and each of these joining pieces has on its lateral surface, in its internal section 3a, 3b, a collar 5b, 6b abutting against an internal shoulder provided in the end section of the sleeve.

Description

La présente invention concerne un galet encliquetable ainsi qu'un rail pourvu de tels galets. The present invention relates to a snap-on roller and a rail provided with such rollers.

On utilise couramment, dens le domaine de la manutention de charges quelconques, des rails sur lesquels sont montées des successions de galets supportant les charges au cours du déplacement de celles-ci. Pour des raisons économiques évidentes on a cherché à abaisser le plus possible le prix de revient de tels rails supports de galets et ce notamment en facilitant au maximum l'opération de montage des galets sur chaque rail. Rails are commonly used in the field of handling any loads, on which successive rollers of rollers supporting the loads are mounted during the movement of the latter. For obvious economic reasons, attempts have been made to lower the cost price of such roller support rails as much as possible, in particular by making the operation of mounting the rollers on each rail as easy as possible.

On a déjà envisagé d'équiper les rails de galets encliquetables et suivant une solution connue le moyeu de chaque galet est engagé à force entre les deux ailes d'un rail à section droite en U, cet engagement tant rendu possible en tirant parti de l'élasticité du métal constituant le rail. En fin d'engagement les deux extrémités du moyeu du galet viennent se placer dans deux logements récepteurs emboutis en creux l'un en face de l'autre, dans les faces internes des deux ailes du rail. It has already been envisaged to equip the rails with snap-on rollers and, according to a known solution, the hub of each roller is forcibly engaged between the two wings of a U-section rail, this engagement being made possible by taking advantage of the elasticity of the metal constituting the rail. At the end of engagement, the two ends of the roller hub are placed in two hollow recesses receiving one opposite the other, in the inner faces of the two wings of the rail.

Un tel procédé de montage d'un rail porte-galets, s'il est avantageux du fait qu'il simplifie, dans une cértaine mesure, la mise en place de chaque galet, n'en présente pas moins l'inconvénient d'exiger une préparation particulière du rail en ce qui concerne la formation des logements emboutis devant recevoir les deux extrémités opposées du moyeu de chaque galet. Or cette préparation du rail accroit sensiblement le prix de revient de l'ensemble du rail porte-galets obtenu finalement. Such a method of mounting a roller-bearing rail, if it is advantageous because it simplifies, to a certain extent, the positioning of each roller, has the disadvantage of requiring a particular preparation of the rail with regard to the formation of stamped housings to receive the two opposite ends of the hub of each roller. However, this preparation of the rail appreciably increases the cost price of the assembly of the roller-bearing rail finally obtained.

La présente invention vise à remédier à cet inconvénient en procurant un galet de conception particulièrement simple et dont la mise en place s'effectue très aisément dans un rail dont l'usinage est considérablement simplifié. The present invention aims to remedy this drawback by providing a roller of particularly simple design and the installation of which is very easily carried out in a rail whose machining is considerably simplified.

A cet effet ce galet encliquetable, monté à rotation sur un axe, par l'intermédiaire d'un roulement, est caractérisé en ce que l'axe est constitué par un manchon è l'intérieur duquel sont montés à coulissement axial deux embouts repoussés vers l'extérieur par un ressort de compression disposé entre eux et chacun de ces embouts présente sur sa surface latérale, dans sa partie interne, une collerette venant en butée contre un épaulement interne prévu-dans la partie extrême du manchon. For this purpose this snap-on roller, mounted for rotation on an axis, by means of a bearing, is characterized in that the axis consists of a sleeve inside which are axially slidably mounted two end pieces pushed towards the outside by a compression spring disposed between them and each of these end pieces has on its lateral surface, in its internal part, a flange abutting against an internal shoulder provided in the extreme part of the sleeve.

L'invention a également pour objet un railprésentant une section droite en U et sur lequel sont montés plusieurs galets encliquetables, les uns à la suite des autres, caractérisé en ce que les parties externes des deux embouts de chaque galet coulissant axialement dans le manchon sont logées respectivement dans deux trous coaxiaux percés de part en part dans les deux ailes du rail en U. The invention also relates to a rail having a U-shaped cross section and on which are mounted several snap-on rollers, one after the other, characterized in that the external parts of the two ends of each roller axially sliding in the sleeve are housed respectively in two coaxial holes drilled right through in the two wings of the U-shaped rail.

On décrira ci-après, à titre d'exemple non limitatif, une forme d'exécution de la présente invention,en référence au dessin annexé qui est une vue en coUpe transversale d'un rail sur lequel est monté un galet encliquetable suivant l'invention. An embodiment of the present invention will be described below, by way of non-limiting example, with reference to the appended drawing which is a cross-sectional view of a rail on which is mounted a snap-on roller according to the invention.

Le galet encliquetable représenté sur le dessin qui peut avoir une surface latérale cylindrique, comme il est indiqué en trait plein, ou pourvue d'une jupe frontale telle qu'indiqué en trait mixte, comprend un corps de révolution 1, réalisé de préférence en matière plastique moulée, lequel est monté à rotation, par l'intermédiaire de roulements 2, sur un axe 3 le traversant de part en part. Cet axe 3 est constitué par un manchon 4, avantageusement en métal, qui constitue la cage interne commune des roulements 2, qui fait saillie de part et d'autre des deux faces frontales du corps 1 du galet, et à l'intérieur duquel sont montés, à coulissement axial, deux embouts 5, 6 repoussés vers l'extérieur par un ressort de compression 7 logé entre eux.Chacun des embouts 5, 6 comprend une partie externe 5a, 6a de petit diamètre et qui est prolongée à l'intérieur par une jupe 5b, 6b de plus grand diamètre, des collerettes annulaires 5c, 6c étant ainsi respectivement formées dans les zones de jonction des deux parties 5a, 5b et 6a, 6b. Les jupes 5b, 6b contribuent à assurer un guidage correct des embouts 5, 6 lors de leur coulissement axial.  The snap-on roller shown in the drawing which may have a cylindrical lateral surface, as indicated in solid lines, or provided with a front skirt as indicated in phantom, comprises a body of revolution 1, preferably made of material molded plastic, which is rotatably mounted, by means of bearings 2, on an axis 3 passing right through it. This axis 3 is constituted by a sleeve 4, advantageously made of metal, which constitutes the common internal cage of the bearings 2, which projects on either side of the two end faces of the body 1 of the roller, and inside which are mounted, axially sliding, two end pieces 5, 6 pushed outwards by a compression spring 7 housed therebetween. Each end piece 5, 6 comprises an external part 5a, 6a of small diameter and which is extended inside by a skirt 5b, 6b of larger diameter, annular flanges 5c, 6c thus being respectively formed in the areas of junction of the two parts 5a, 5b and 6a, 6b. The skirts 5b, 6b help to ensure correct guidance of the end pieces 5, 6 during their axial sliding.

Par ailleurs le manchon 4 est pourvu, à l'une de ses
extrémités, d'un épaulement interne annulaire 4a, qui fait partie intégrante du manchon 4 et, à son autre extrémité, d'une rondelle rapportée 4b, emboîtée 9 force, formant éga
lement épaulement annulaire. Les épaulements annulaires 4a et 4b constituent des butées contre lesquelles viennent s'appliquer les collerettes 5c, 6c des embouts 5, 6, sous l'action du ressort 7. Ce ressort prend appui, à ses extrémités, sur les fonds des creux délimités, dans les parties internes des deux embouts 5, 6, par les jupes respectives 5b, 6b.Furthermore, the sleeve 4 is provided, at one of its
ends, of an annular internal shoulder 4a, which is an integral part of the sleeve 4 and, at its other end, of an attached washer 4b, nested 9 force, forming also
annular shoulder element. The annular shoulders 4a and 4b constitute stops against which the flanges 5c, 6c of the end pieces 5, 6 are applied, under the action of the spring 7. This spring bears, at its ends, on the bottoms of the delimited hollows, in the internal parts of the two end pieces 5, 6, by the respective skirts 5b, 6b.

Le galet encliquetable suivant l'invention est représenté, sur le dessin, monté sur un rail 8 à section droite en U. Les deux ailes 8a, 8b de ce rail 8 sont percées de trous en regard 9, alignés transversalement et formant des logements pour les parties externes 5a, 6a de petit diamètre des embouts 5, 6. The snap-on roller according to the invention is shown in the drawing, mounted on a rail 8 with a U-shaped cross section. The two wings 8a, 8b of this rail 8 are pierced with facing holes 9, aligned transversely and forming housings for the external parts 5a, 6a of small diameter of the end pieces 5, 6.

On voit d'après la description qui précède que le montage du galet encliquetable dans ie rail 8 s'effectua très aisément et très rapidement. Il suffit en effet de repousser vers l'intérieur les deux embouts 5, 6, à lten- contre de l'action du ressort de compression 7, pour amener la distance entre les extrémités de ces embouts à être inférieure ou égale à la distance entre les deux ailes Sa, 8b du rail 8. Ensuite il suffit d'enfoncer le galet en direction de l'âme du rail 8, les deux embouts 5, 6 glissant par leurs faces frontales externes sur les faces internes des deux ailes 8a, 8b, jusqu'à ce que ces embouts viennent s'engager dans les deux trous en regard 9. On voit donc que l'opéra- tion de montage est considérablement simplifiée et que le prix de revient de l'ensemble du rail porte-galets est con- sidérablement abaissé, et ce pour trois raisons:
1) le prix de revient du galet à axe à ressort n'est
pas supérieur au prix des galets utilisés habituel
lement avec ou sans axe;
2) le montage du galet dans le rail est très rapide;
3) le rail dont la conception et très simple, est
d'un coût de revient limité. It can be seen from the above description that the mounting of the snap-on roller in the rail 8 was carried out very easily and very quickly. It suffices in fact to push the two ends 5, 6 inward, against the action of the compression spring 7, to bring the distance between the ends of these ends to be less than or equal to the distance between the two wings Sa, 8b of the rail 8. Then it suffices to push the roller in the direction of the core of the rail 8, the two end pieces 5, 6 sliding by their external end faces on the internal faces of the two wings 8a, 8b , until these end pieces engage in the two opposite holes 9. It can therefore be seen that the mounting operation is considerably simplified and that the cost price of the whole of the roller-bearing rail is Considerably lowered, for three reasons:
1) the cost price of the spring-loaded roller is
not higher than the price of the usual rollers
with or without axis;
2) mounting the roller in the rail is very quick;
3) the rail whose design and very simple, is
a limited cost price.
