Description
Roulement à billes on à rouleaux. L'objet de la présente invention est un roulement à billes ou à rouleaux, dans lequel le chemin intérieur de roulement peut exécu ter un mouvement axial relativement au che min extérieur dudit roulement, caractérisé en ce qu'il comporte une cuvette qui maintient ensemble par sertissage le chemin de roule ment extérieur et au moins une pièce de butée limitant dans un sens le mouvement axial du chemin de roulement intérieur.
Le dessin annexé représente, à titre -d'exemple, trois formes d'exécution de l'objet de l'invention.
Dans toutes les figures, les pièces sem blables ou analogues sont désignées par les mêmes chiffres de référence.
Dans la fig. 1, le roulement comporte un chemin de roulement extérieur comportant deux bagues 2 et 2', sur la périphérie interne desquelles roulent les billes 3 contenues dans une cage 13. Le chemin de roulement inté rieur est constitué par une surface cylindri que de l'arbre 5. Cette .surface est polie de manière à offrir d'excellentes conditions de roulement et -de glissement. Le jeu compris entre cette surface et les billes 3, même s'il est réduit à 0,005 mm, permet facilement le glissement axial de l'arbre 5.
Les bagues 2 et 2' sont logées avec l'in- terpasition d'une cale 9 dans une cuvette 8 en même temps qu'une plaque de butée axiale 7'. Les bagues 2 et 2', la cale 9 et la plaque de butée 7' sont maintenues ensemble dans la cuvette par sertissage. La plaque de butée limite le mouvement axial de l'arbre dans un sens et elle pourrait être garnie d'une pierre contre-pivot sur laquelle l'extrémité de l'arbre 5 s'appuyerait.
Dans l'exemple de la fig. 2, le roulement est analogue à celui représenté en fig. 1, le chemin de roulement extérieur des billes étant constitué de la même façon. La plaque de butée 6, cependant, est percée en son centre pour laisser passer l'arbre 5 et est polie du côté de la portée 5' de. l'arbre 5 dont une partie cylindrique constitue le chemin inté rieur de roulement. Cette portée 5' bute contre la plaque pour limiter le mouvement axial de l'arbre.
Si les pressions axiales reçues par les arbres sont fortes, on utilisera le roulement à billes représenté en fig. 3. La butée limitant le mouvement axial de l'arbre de ce roule ment comporte une pièce de butée 70 dans l'enfoncement central de laquelle des billes 11 roulent. Le chemin de roulement extérieur est constitué de la même façon que dans le roulement de la fig. 1, les pièces de ce che min ainsi que la pièce de butée 70 et une rondelle 10 étant maintenues ensemble dans la cuvette 8 par sertissage.
La rondelle 10, logée entre la bague exté rieure de roulement 2' et la pièce 70 empêche les billes 11 de sortir du roulement lorsque l'arbre 5 n'est pas en place.
La douille 4, trempée et polie, constitue le chemin intérieur de roulement. Elle est chassée sur l'arbre 5.
Ball or roller bearings. The object of the present invention is a ball or roller bearing, in which the inner raceway can perform an axial movement relative to the outer race of said bearing, characterized in that it comprises a cup which holds together by crimping the outer raceway and at least one stop piece limiting in one direction the axial movement of the inner raceway.
The appended drawing represents, by way of example, three embodiments of the object of the invention.
In all the figures, similar or similar parts are designated by the same reference numerals.
In fig. 1, the bearing comprises an outer raceway comprising two rings 2 and 2 ', on the inner periphery of which the balls 3 contained in a cage 13 roll. The inner raceway is formed by a cylindrical surface of the shaft 5. This surface is polished so as to provide excellent running and sliding conditions. The clearance between this surface and the balls 3, even if it is reduced to 0.005 mm, easily allows the axial sliding of the shaft 5.
The rings 2 and 2 'are accommodated with the interposition of a wedge 9 in a cup 8 at the same time as an axial stop plate 7'. The rings 2 and 2 ', the wedge 9 and the stop plate 7' are held together in the cup by crimping. The stop plate restricts the axial movement of the shaft in one direction and it could be lined with a counter-pivot stone on which the end of the shaft 5 would rest.
In the example of FIG. 2, the bearing is similar to that shown in fig. 1, the outer raceway of the balls being made in the same way. The stopper plate 6, however, is drilled through its center to allow the shaft 5 to pass and is polished on the 5 'seat side. the shaft 5, a cylindrical part of which constitutes the internal raceway. This bearing 5 'abuts against the plate to limit the axial movement of the shaft.
If the axial pressures received by the shafts are high, the ball bearing shown in fig. 3. The stop limiting the axial movement of the shaft of this bearing comprises a stop piece 70 in the central recess of which balls 11 roll. The outer race is made in the same way as in the bearing of fig. 1, the parts of this path as well as the stop piece 70 and a washer 10 being held together in the cup 8 by crimping.
The washer 10, housed between the outer bearing ring 2 'and the part 70 prevents the balls 11 from coming out of the bearing when the shaft 5 is not in place.
The bush 4, hardened and polished, constitutes the internal raceway. She is hunted on tree 5.
