Description
ROULEMENT A BILLES SUR JOUES DE FIL D'ACIER, OFFRANTBALL BEARING ON STEEL THREADS, OFFERING
UNE LIBERTE DE MOUVEMENT ACCRUEMORE FREEDOM OF MOVEMENT
La présente invention se rapporte à un roulement à billes sur joues de fil d'acier, notamment pour palier de colonne de direction, constitué par deux fils de roulement intérieurs qui prennent appui sur une bague intérieure à rebords dirigés radialement vers l'extérieur, par deux fils de roulement extérieurs qui prennent appui dans une bague extérieure dotée de rebords dirigés radialement vers l'intérieur, et par des corps roulants, un fil de roulement étant agencé avec possibilité de déplacement axial et étant sollicité par un ressort qui prend appui contre une The present invention relates to a ball bearing on steel wire flanges, especially for a steering column bearing, consisting of two inner raceways which bear on an inner ring with flanges directed radially outwards, by two outer races which bear in an outer ring provided with radially inwardly directed flanges, and by rolling bodies, a rolling wire being arranged with the possibility of axial displacement and being biased by a spring which bears against a
surface d'un rebord.surface of a rim.
De tels roulements à billes sur Joues de fil d'acier sont déjà connus C'est ainsi que, par exemple du fait du brevet britannique 1 007 191, il n'est plus nouveau d'effectuer le serrage des parties du roulement par un ressort à surface de contact conique, exerçant une contrainte vers l'extérieur, ce ressort prenant appui contre une surface conique correspondante de la bague extérieure et appliquant le premier fil de roulement contre les billes et-ces dernières contre les autres fils de roulement Ce dispositif connu est constitué par une série de pièces détachées et est relativement onéreux à fabriquer En outre, le serrage des pièces du roulement exige un ressort relativement fort, de sorte que le roulement ne possède pas une liberté de mouvement suffisante pour de nombreux cas d'application. L'invention a pour but de réaliser un roulement à billes sur Joues de fil d'acier du type indiqué au début, qui pourra être réalisé de manière économiquement avantageuse et présentera une excellente Such ball bearings on steel wire cheeks are already known Thus, for example because of British Patent 1,007,191, it is no longer new to tighten the parts of the bearing by a spring with conical contact surface, exerting a constraint towards the outside, this spring bearing against a corresponding conical surface of the outer ring and applying the first bearing wire against the balls and the latter against the other rolling threads This known device It consists of a series of spare parts and is relatively expensive to manufacture. Moreover, the clamping of the bearing parts requires a relatively strong spring, so that the bearing does not have sufficient freedom of movement for many applications. The object of the invention is to provide a ball bearing on cheeks of steel wire of the type indicated at the beginning, which can be economically advantageous and will have excellent results.
liberté de mouvement.freedom of movement.
Selon l'invention, ce but est atteint par le fait qu'une rondelle- ressort prévue entre un fil de roulement et un rebord est précontrainte en direction axiale à un point tel que la surface périphérique de cette rondelle-ressort se trouve située contre une surface d'un élément élastique inséré entre la surface According to the invention, this object is achieved by the fact that a spring washer provided between a rolling wire and a flange is prestressed axially to a point such that the peripheral surface of this spring washer is located against a surface of an elastic element inserted between the surface
périphérique et l'alésage de la bague extérieure. peripheral and the bore of the outer ring.
Cette configuration permet d'utiliser une rondelle-ressort relativement faible pour le serrage des parties du roulement, puisque la rondelle-ressort pénètre dans l'élément élastique lors de l'aplatissement Il en résulte que l'ensemble du système élastique présente une caractéristique élastique correspondant à celle d'une rondelle-ressort plus forte, c'est-à-dire qu'il faut une force This configuration makes it possible to use a relatively small spring washer for clamping the parts of the bearing, since the spring washer penetrates the elastic element during the flattening. As a result, the entire elastic system has an elastic characteristic. corresponding to that of a stronger spring washer, that is to say it requires a force
relativement grande pour déplacer la bague intérieure. relatively large to move the inner ring.
Parmi les formes de réalisation possibles, l'invention prévoit notamment que: la rondelle-ressort et les fils de roulement sont disposés contre la surface d'alésage d'un manchon intermédiaire élastique; le manchon intermédiaire présente en une extrémité un saillant circonférentiel dirigé radialement vers l'intérieur; le saillant est disposé de manière à limiter la course de déformation de la rondelle-ressort; et le manchon intermédiaire a une section droite en forme de L et présente, dans sa surface périphérique, Among the possible embodiments, the invention provides in particular that: the spring washer and the rolling threads are disposed against the bore surface of an elastic intermediate sleeve; the intermediate sleeve has at one end a radially inwardly directed circumferential projection; the projection is arranged to limit the deformation of the spring washer; and the intermediate sleeve has an L-shaped cross-section and has, in its peripheral surface,
des rainures dirigées axialement.grooves directed axially.

l'invention apparaîtront dans la description présentée the invention will appear in the description presented
ci-après à titre d'exemple non limitatif en se hereinafter by way of non-limiting example in
reportant à la figure unique du dessin annexé. referring to the single figure of the attached drawing.
Le roulement à billes sur joues de fil d'acier représenté sur la figure est constitué par une bague extérieure en tôle 1 avec deux rebords 2, 3 dirigés radialement vers l'intérieur, par un manchon intermédiaire 5 réalisé de préférence en caoutchouc et agencé dans l'alésage 4 de la bague extérieure 1, par une bague intérieure 6 à section droite en forme de U, par deux fils de roulement 8, 9 s'appliquant sur la surface 7 de l'alésage du manchon intermédiaire 5, par les billes 12 prévues entre les fils de roulement 8, 9, , Il et par une rondelle-ressort 13, du genre Belleville, qui applique le fil de roulement 8 contre les billes 12 et les billes 12 contre les autres fils de roulement 9, 10, 11 Le manchon intermédiaire 5 est réalisé avec une section droite en forme de L et présente dans sa périphérie des rainures 14 dirigées axialement, lesquelles confèrent au manchon The ball bearing on steel wire cheeks shown in the figure is constituted by an outer ring sheet 1 with two flanges 2, 3 directed radially inwards, by an intermediate sleeve 5 preferably made of rubber and arranged in the bore 4 of the outer ring 1, by an inner ring 6 U-shaped cross section, by two rolling threads 8, 9 on the surface 7 of the bore of the intermediate sleeve 5, by the balls 12 provided between the rolling threads 8, 9, 11 and by a spring washer 13, of the Belleville type, which applies the rolling wire 8 against the balls 12 and the balls 12 against the other rolling threads 9, 10, The intermediate sleeve 5 is made with an L-shaped cross-section and has in its periphery grooves 14 directed axially, which give the sleeve
