Description
Palier destiné à accueillir un axe tournantBearing intended to accommodate a rotating axis
L'invention se rapporte à un palier destiné à accueillir un axe tournant. The invention relates to a bearing intended to receive a rotary axis.
Le palier selon l'invention peut être utilisé notamment pour guider un entraîneur de transmission transversale suivant l'axe d'un différentiel d'un véhicule automobile. The bearing according to the invention can be used in particular to guide a transverse transmission drive along the axis of a differential of a motor vehicle.
Un tel palier comporte en général une embase prévue pour être fixée sur un support, au moins un alésage destiné à 10 accueillir l'axe tournant et son roulement. Un roulement est en effet interposé entre le palier et l'arbre tournant, pour permettre une liaison pivot entre le palier et l'arbre. A cet effet, une pièce de serrage, destinée à être fixée sur l'embase, est prévue pour encastrer et maintenir le roulement de l'axe is tournant dans le palier. Such a bearing generally comprises a base intended to be fixed on a support, at least one bore intended to accommodate the rotary axis and its bearing. A bearing is in fact interposed between the bearing and the rotating shaft, to allow a pivot connection between the bearing and the shaft. For this purpose, a clamping piece, intended to be fixed on the base, is provided for embedding and maintaining the bearing of the axis is rotating in the bearing.
On connaît de tels paliers dans lesquels l'embase comporte des alésages prévus pour permettre la fixation de la pièce de serrage au moyen d'écrous et de vis dites " talon ". There are known such bearings in which the base has bores provided to allow the fixing of the clamping piece by means of nuts and screws called "heel".
Cependant, ce type de dispositif présente de nombreux 20 inconvénients. En effet, en raison de l'espace toujours plus réduit dans les véhicules, la fixation de la pièce de serrage devient très difficile pour un opérateur. En particulier, il devient très malaisé d'utiliser une visseuse automatique. De plus, cette opération de montage s'avère longue, complexe et 25 fastidieuse pour l'opérateur. However, this type of device has many drawbacks. Indeed, due to the ever-reduced space in vehicles, the fixing of the clamping piece becomes very difficult for an operator. In particular, it becomes very difficult to use an automatic screwdriver. In addition, this assembly operation proves to be long, complex and tedious for the operator.
Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus. An object of the present invention is to overcome all or part of the drawbacks of the prior art noted above.
A cette fin, le palier selon l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule 30 ci-dessus, est essentiellement caractérisé en ce que la pièce de serrage a la forme générale d'un demi-anneau qui comprend deux orifices situés respectivement au niveau de ses deux extrémités et destinés à coopérer respectivement avec deux vis de fixation et deux trous taraudés formés sur l'embase. Par ailleurs, l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes: - l'embase et la pièce de serrage ont des formes conjuguées de façon à permettre la fixation par vissage d'une première extrémité de la pièce de serrage au niveau d'un premier trou taraudé de l'embase, puis la rotation de l'embase io autour de cette première extrémité pour faire concider le second orifice de la pièce de serrage avec le second trou taraudé de l'embase, - l'embase et/ou la pièce de serrage comporte des moyens formant b utée l imitant la rotation de la pièce de serrage par i5 rapport à l'embase, de façon à faire concider le second orifice de la pièce de serrage avec le second trou taraudé de l'embase, - l'embase comporte des moyens formant butée situés de part et d'autre de l'alésage et destinés à coopérer 20 respectivement avec les deux extrémités de la pièce de serrage pour faire concider les orifices de cette dernière avec respectivement les deux trous taraudés de l'embase, - l'un au moins des orifices de la pièce de serrage est débouchant de façon à former une encoche permettant le 25 montage de l'encoche sur une vis pré-vissée de façon partielle dans un trou taraudé de l'embase. To this end, the bearing according to the invention, furthermore in accordance with the generic definition given by the preamble 30 above, is essentially characterized in that the clamping part has the general shape of a half-ring which comprises two orifices located respectively at its two ends and intended to cooperate respectively with two fixing screws and two tapped holes formed on the base. Furthermore, the invention may include one or more of the following characteristics: - the base and the clamping piece have conjugate shapes so as to allow fixing by screwing of a first end of the clamping piece at the level of a first tapped hole in the base, then the rotation of the base io around this first end to make the second orifice of the clamping piece coincide with the second tapped hole in the base, - the base and / or the clamping piece comprises means forming a socket imitating the rotation of the clamping piece by i5 relative to the base, so as to make the second orifice of the clamping piece reconcile with the second tapped hole of the base, - the base comprises means forming an abutment located on either side of the bore and intended to cooperate respectively with the two ends of the clamping part to make the orifices of the latter conciliate with the two respectively tapped holes in the base, - at least one of the orifices in the clamping part opens out so as to form a notch allowing the notch to be mounted on a partially pre-screwed screw in a tapped hole the base.
D'autres particularités et avantages apparaîtront à la lecture de la description ci-après faite en référence aux figures dans lesquelles: - la figure 1 représente une vu en en perspective d'un palier selon un mode de réalisation préféré de l'invention, - la figure 2 représente une vu en en perspective d'un détail de la figure 1, illustrant le montage d'un élément de serrage sur l'embase du palier, - la figure 3 représente un second mode de réalisation 5 d'une pièce de serrage destinée à coopérer avec l'embase du palier selon l'invention. Other particularities and advantages will appear on reading the description below made with reference to the figures in which: - Figure 1 shows a perspective view of a bearing according to a preferred embodiment of the invention, - 2 shows a perspective view of a detail of Figure 1, illustrating the mounting of a clamping element on the base of the bearing, - Figure 3 shows a second embodiment 5 of a piece of tightening intended to cooperate with the bearing base according to the invention.
L'invention va à présent être décrite en référence aux figures 1 et 2. The invention will now be described with reference to FIGS. 1 and 2.
Le palier 1 selon l'invention comprend classiquement une 10 embase 2 prévue pour être fixée sur un support, tel que la structure d'un véhicule. L'embase 2 peut être constituée de métal, tel que de la fonte et/ou de l'aluminium. The bearing 1 according to the invention conventionally comprises a base 2 intended to be fixed on a support, such as the structure of a vehicle. The base 2 can be made of metal, such as cast iron and / or aluminum.
L'embase comporte au moins un alésage 3 destiné à accueillir un axe tournant et son roulement (non représentés 15 par soucis de simplification). Un autre alésage 4 peut être prévu pour accueillir une biellette anti-couple par exemple. Le palier 1 comporte également une pièce de serrage 5 destinée à être fixée sur l'embase 2, pour encastrer le roulement de l'axe tournant dans le palier 1. The base includes at least one bore 3 intended to accommodate a rotary axis and its bearing (not shown for simplification purposes). Another bore 4 can be provided to accommodate an anti-torque rod for example. The bearing 1 also includes a clamping piece 5 intended to be fixed on the base 2, to embed the bearing of the rotating axis in the bearing 1.
Selon l'invention, la pièce de serrage 5 a la forme générale d'un demianneau dont chacune des deux extrémités comporte un orifice 6, 7. According to the invention, the clamping piece 5 has the general shape of a half-ring, each of the two ends of which has an orifice 6, 7.
Les orifices 6, 7 de la pièce de serrage 5 sont prévus pour permettre le passage respectivement de deux vis d e f ixation 25 destinées à être vissées dans des trous taraudés 9, 8 formés dans l'embase 2. Plus précisément, les trous taraudés 9, 8 de l'embase 2 sont situés sensiblement de part et d'autre de l'alésage 3, de façon que, en position montée, la pièce de serrage 5 épouse une partie de la bordure circulaire de 30 l'alésage 3. The orifices 6, 7 of the clamping part 5 are provided to allow the passage respectively of two fixing screws 25 intended to be screwed into tapped holes 9, 8 formed in the base 2. More precisely, the tapped holes 9, 8 of the base 2 are located substantially on either side of the bore 3, so that, in the mounted position, the clamping piece 5 follows part of the circular edge of the bore 3.
L'invention p ermet a insi d 'éviter I 'utilisation d'écrou pour le montage de la pièce de serrage 5 et rend plus facile et plus rapide le montage d'un arbre et de son roulement dans le palier 1. Par ailleurs, on constate que la pièce de serrage 5 selon l'invention et son montage confèrent une meilleure tenue au roulement et à l'axe tournant dans le palier 1. The invention allows insi to avoid the use of nut for mounting the clamping piece 5 and makes it easier and faster to mount a shaft and its bearing in the bearing 1. Furthermore, it can be seen that the clamping piece 5 according to the invention and its mounting give better resistance to the rolling and to the rotating axis in the bearing 1.
De préférence, l'opérateur fixe une première extrémité de 5 la pièce de serrage 5 sur l'embase 2 en faisant passer une vis dans un premier orifice 6 de la pièce de serrage 5 et en vissant cette vis dans un premier trou taraudé 9 de l'embase 2 (figure 2). Preferably, the operator fixes a first end of 5 the clamping piece 5 on the base 2 by passing a screw through a first orifice 6 of the clamping piece 5 and by screwing this screw into a first tapped hole 9 of base 2 (figure 2).
L'embase 2 et la pièce de serrage 5 ont de préférence des 10 formes conjuguées, de façon à permettre ensuite la rotation de la pièce de serrage 5 autour de cette première extrémité 6, pour faire concider le second orifice 7 de la pièce de serrage avec le second trou taraudé 8 de l'embase 2. The base 2 and the clamping piece 5 preferably have conjugate shapes, so as to then allow the rotation of the clamping piece 5 around this first end 6, to make the second orifice 7 of the clamping piece conciliate with the second threaded hole 8 of the base 2.
Avantageusement, l'embase 2 et/ou la pièce de serrage 5 15 comportent des m oyens 1 0 f ormant b utée l imitant I a r otation de la pièce de serrage 5 par rapport à l'embase 2, de façon à faire concider le second orifice 7 de la pièce de serrage 5 avec le second trou taraudé 8 de l'embase 2. Advantageously, the base 2 and / or the clamping piece 5 15 comprise means 1 0 f ormant b utée l imitation I ar otation of the clamping piece 5 relative to the base 2, so as to reconcile the second orifice 7 of the clamping piece 5 with the second threaded hole 8 of the base 2.
L'opération de montage se t rouve a insi f acilitée p our u n 20 opérateur et sa durée réduite. The assembly operation is insi facilit y for an operator and its reduced duration.
Les moyens 10 formant butée peuvent être constitués d'au moins un épaulement 10 formé sur l'embase 2, à proximité d'un t rou 8 t araudé. B ien e ntendu, i I e st possible de prévoir des moyens 10, 11 formant butée situés de part et d'autre de 25 l'alésage 3 et destinés à coopérer respectivement avec les deux extrémités de la pièce de serrage 5. De cette façon, l'opérateur peut facilement faire concider les orifices 7, 6 de la pièce de serrage avec respectivement les deux trous taraudés 8, 9 de l'embase 2. The means 10 forming a stop may consist of at least one shoulder 10 formed on the base 2, near a t rou 8 t tapped. Of course, it is possible to provide means 10, 11 forming a stop located on either side of the bore 3 and intended to cooperate respectively with the two ends of the clamping piece 5. From this In this way, the operator can easily reconcile the orifices 7, 6 of the clamping piece with the two tapped holes 8, 9 of the base 2 respectively.
Comme représenté à la figure 3, l'un 7 au moins des orifices 6, 7 de la pièce de serrage 5 peut être formé débouchant, c'est à dire qu'il forme une encoche. Cette encoche 7 peut ainsi être montée sur une vis prévissée de façon partielle dans un trou taraudé 8 de l'embase 2. C'est-àdire que, lors de la rotation de la pièce de serrage 5 autour d'une première extrémité vissée 6, la seconde extrémité comportant l'encoche 7 vient s'engager sur la seconde vis prévissée dans le second trou 8 taraudé. Lorsque cette encoche 7 5 est montée sur la seconde vis, l'opérateur peut ensuite terminer le vissage de cette seconde vis dans le trou taraudé 8. Cette dernière variante de réalisation facilite et réduit encore le temps de montage de la pièce de serrage 5 autour 10 de l'arbre et de son roulement. En effet, ce mode de réalisation de l'invention permet un pré-montage de la pièce de serrage et des deux vis de fixation, préalablement à l'introduction de l'arbre et de son roulement dans l'alésage 3 de l'embase 2. As shown in FIG. 3, at least one 7 of the orifices 6, 7 of the clamping piece 5 can be formed through, that is to say that it forms a notch. This notch 7 can thus be mounted on a screw partially screwed into a threaded hole 8 of the base 2. That is to say that, during the rotation of the clamping piece 5 around a first screwed end 6 , the second end comprising the notch 7 engages on the second screw provided in the second tapped hole 8. When this notch 7 5 is mounted on the second screw, the operator can then complete the screwing of this second screw in the tapped hole 8. This last variant of embodiment facilitates and further reduces the assembly time of the clamping piece 5 around 10 of the shaft and its bearing. In fact, this embodiment of the invention allows pre-assembly of the clamping piece and of the two fixing screws, prior to the introduction of the shaft and its bearing into the bore 3 of the base. 2.
Ainsi, l'invention tout en étant de structure simple et peu coteuse, permet de résoudre avantageusement les problèmes de l'art antérieur. Thus, the invention while being simple and inexpensive in structure, makes it possible to advantageously solve the problems of the prior art.
