Abstract

The retaining piece for ball bearings in a bicycle hub consists of a pair of flanges (1) for the retention of the ball bearings and a body of the hub (2). Each bearing retainer has an integrated cup (11) which extends towards the exterior and is made up of a cavity (13). A flange (12) extends from the extreme end opposed to that of the integrated cup. This flange contains holes (121) for the acceptance of the wheel spokes.

Description

Dispositifs de retenue de roulements pour un moyeu de bicyclette
La présente invention concerne des dispositifs de retenue de roulements et, plus particulièrement, des dispositifs de retenue de roulements avec cuvette intégrée, destinés au moyeu d'une bicyclette.Bearing retainers for a bicycle hub
The present invention relates to bearing retainers and, more particularly, to bearing retainers with an integrated cup, intended for the hub of a bicycle.

Une paire de dispositifs de retenue de roulements est installée sur le moyeu d'une bicyclette pour transférer les forces des deux pédales à la roue motrice afin de faire avancer la bicyclette. A pair of bearing retainers is installed on the hub of a bicycle to transfer the forces from the two pedals to the drive wheel to advance the bicycle.

Un dispositif de retenue de roulement de l'art antérieur, représenté à la figure 3, comprend un corps de moyeu C avec deux dispositifs de retenue de roulements A et deux cuvettes B qui sont ensuite emboîtés de force dans les extrémités respectives du corps de moyeu C. Le dispositif de retenue A et la cuvette B sont usinés séparément, ce qui peut produire des imprécisions d'alignement entre eux et des difficultés pour les emboîter. En outre, le défaut d'alignement va produire une force de cisaillement irrégulière sur le dispositif de retenue A et la cuvette B et, par conséquent réduire leur durée de vie. A prior art bearing retainer, shown in Figure 3, includes a hub body C with two bearing retainers A and two cups B which are then force fitted into the respective ends of the hub body C. The retainer A and the bowl B are machined separately, which can produce inaccuracies in alignment between them and difficulties in fitting them. In addition, the misalignment will produce an irregular shear force on the retainer A and the bowl B and therefore reduce their service life.

Au vu de ces inconvénients, le demandeur a proposé la présente invention pour offrir un dispositif de retenue de roulement amélioré avec une cuvette intégrée. In view of these drawbacks, the applicant has proposed the present invention to offer an improved bearing retainer with an integrated cup.

Le principal objet de la présente invention est donc de proposer des dispositifs de retenue de roulements qui ont une cuvette intégrée en une de leurs extrémités. The main object of the present invention is therefore to provide bearing retaining devices which have an integrated cup at one of their ends.

Un autre objet de la présente invention est de proposer un dispositif de retenue de roulement avec une cuvette intégrée, destiné à un moyeu de bicyclette, qui soit plus solide et qui ait une durée de vie importante.  Another object of the present invention is to provide a bearing retainer with an integrated cup, intended for a bicycle hub, which is more solid and has a long service life.

Un autre objet de la présente invention est de proposer un dispositif de retenue de roulement avec une cuvette intégrée, destiné à un moyeu de bicyclette, qui soit facile à assembler et peu coûteux à fabriquer. Another object of the present invention is to provide a bearing retainer with an integrated cup, intended for a bicycle hub, which is easy to assemble and inexpensive to manufacture.

La présente invention sera mieux comprise à la lecture de la description suivante, prise en liaison avec les dessins d'accompagnement, dans lesquels
la figure 1 est une vue en perspective d'un corps de moyeu et de deux dispositifs de retenue de roulements de la présente invention, avant assemblage,
la figure 2 est une vue en coupe du corps de moyeu et des dispositifs de retenue de roulements de la figure 1, après assemblage, et
la figure 3 est une vue en coupe d'un corps de moyeu de la technique antérieure, aux extrémités respectives duquel est montée une paire de dispositifs de retenue de roulements.The present invention will be better understood on reading the following description, taken in conjunction with the accompanying drawings, in which
FIG. 1 is a perspective view of a hub body and two bearing retainers of the present invention, before assembly,
FIG. 2 is a sectional view of the hub body and of the bearing retaining devices of FIG. 1, after assembly, and
Figure 3 is a sectional view of a hub body of the prior art, at the respective ends of which is mounted a pair of bearing retainers.

Si on considère maintenant les figures 1 et 2, dont les représentations ne servent qu'à illustrer un mode préféré de réalisation de la présente invention et non à limiter le concept de l'invention à ce qui est représenté, on voit une paire de dispositifs 1 de retenue de roulements et un corps de moyeu 2, cylindrique, qui constituent l'invention. If we now consider Figures 1 and 2, the representations of which serve only to illustrate a preferred embodiment of the present invention and not to limit the concept of the invention to what is shown, we see a pair of devices 1 bearing retainer and a hub body 2, cylindrical, which constitute the invention.

Chaque dispositif 1 de retenue de roulement a une cuvette 11 qui fait corps avec lui et qui s'étend depuis une extrémité du dispositif 1 de retenue de roulement en comportant une cavité 13, un flasque 12 partant de la périphérie de l'extrémité opposée par rapport à la cuvette 11, avec une pluralité de trous 121 équidistants sur le flasque 12. Each bearing retainer 1 has a cup 11 which is integral with it and which extends from one end of the bearing retainer 1 by comprising a cavity 13, a flange 12 starting from the periphery of the end opposite by relative to the bowl 11, with a plurality of holes 121 equidistant on the flange 12.

Chaque trou 121 a deux bords 122 qui dépassent de l'intérieur en ses extrémités respectives. Une partie élargie 112 est formée entre la cuvette 1 1 et le flasque 12 sur chaque dispositif de retenue 1, pour recevoir une partie d'extrémité du corps de moyeu 2. La paroi intérieure de la partie élargie 112 comporte des stries 113 qui produisent une friction quand elles rencontrent la surface d'extrémité du corps de moyeu 2.Each hole 121 has two edges 122 which project from the inside at their respective ends. An enlarged portion 112 is formed between the cup 1 1 and the flange 12 on each retaining device 1, to receive an end portion of the hub body 2. The inner wall of the enlarged portion 112 has ridges 113 which produce a friction when they meet the end surface of the hub body 2.

Des filets 111 sont usinés sur l'une des cuvettes intégrées 11, au niveau de sa partie extérieure, en vue d'un vissage avec un pignon.  Threads 111 are machined on one of the integrated cups 11, at its external part, for screwing with a pinion.

Pour augmenter la flexibilité des produits, les filets 111 peuvent être réalisés avant traitement thermique.To increase the flexibility of the products, the nets 111 can be produced before heat treatment.

Pour assembler la présente invention, on emboîte de force les deux dispositifs 1 de retenue de roulements sur les extrémités respectives du corps de moyeu 2, les stries 113 gravées dans les parties élargies 112 s'accrochant avec les extrémités extérieures respectives du corps de moyeu 2 pour une mise en prise sûre. To assemble the present invention, the two bearing retaining devices 1 are forcibly fitted onto the respective ends of the hub body 2, the ridges 113 etched in the enlarged parts 112 hooking with the respective outer ends of the hub body 2 for secure engagement.

Il est bien entendu que la description qui précède n'a été donnée qu'à titre purement illustratif et non limitatif et que des variantes ou des modifications peuvent y être apportées dans le cadre de la présente invention.  It is understood that the above description has been given purely by way of non-limiting illustration and that variants or modifications may be made thereto within the framework of the present invention.
