Description
- L'invention concerne des perfectionnementsThe invention relates to improvements
apportés à un roulement à billes à gorges profondes. brought to a deep groove ball bearing.
En ce qui concerne les profondeurs des gorges des pistes des roulements à billes à gorges profondes connus jusqu'à présent, la profondeur de la gorge de la piste de la bague extérieure est sensiblement égale à la profondeur de la gorge de la piste de la bague intérieure et la somme de ces profondeurs est inférieure aux rayons des billes utilisées (les billes étant disposées entre la bague extérieure et la bague intérieure). Par conséquent, lorsqu'une charge axiale élevée ou un moment élevé est appliqué au roulement, il se pose un problème selon lequel les billes se déplacent sur l'épaulement de la piste (partie extrême de la surface incurvée de la piste), ce qui provoque des chocs contre les bords et ne permet donc pas une résistance suffisante à la With regard to the groove depths of the deep groove ball bearing tracks known hitherto, the depth of the groove of the outer ring track is substantially equal to the depth of the groove of the ring track and the sum of these depths is less than the radius of the balls used (the balls being disposed between the outer ring and the inner ring). Therefore, when a high axial load or a high moment is applied to the bearing, there is a problem that the balls move on the shoulder of the track (end part of the curved surface of the track), which causes shocks against the edges and therefore does not allow sufficient resistance to the

ment. L'invention est donc destinée à résoudre le problème indiqué cidessus, particulier aux roulements à billes à gorges profondes de l'art antérieur. A cet effet, l'invention concerne un roulement à billes à gorges profondes dans lequel la profondeur h1 de la gorge de la piste de la bague extérieure, la profondeur h2 de la gorge de la piste de la bague intérieure et le diamètre d des billes-satisfont la is lying. The invention is therefore intended to solve the problem indicated above, particular to deep groove ball bearings of the prior art. To this end, the invention relates to a deep groove ball bearing in which the depth h1 of the raceway groove of the outer race, the depth h2 of the groove of the raceway of the inner race and the diameter of the balls. -satisfy the
relation: h1 + h2 Ä d/2.relation: h1 + h2 Δ d / 2.
Par conséquent, dans le roulement à billes à gorges profondes selon l'invention, la somme des profondeurs des gorges de-la bague extérieure et de la bague intérieure est égale ou supérieure au rayon (moitié du diamètre) des billes et, par conséquent, le roulement supporte en fait aussi efficacement une charge radiale qu'une charge axiale, ainsi que les moments de force, et sa durée de vie peut être notablement prolongée. En particulier, cet effet est encore plus prononcé lorsque la-profondeur de la gorge de la bague Therefore, in the deep groove ball bearing according to the invention, the sum of the depths of the grooves of the outer ring and the inner ring is equal to or greater than the radius (half the diameter) of the balls and, therefore, the bearing actually supports radial load as well as axial load, as well as moments of force, and its service life can be significantly extended. In particular, this effect is even more pronounced when the depth of the throat of the ring

rieure. Cependant, si la somme des profondeurs des gorges des bagues extérieure et intérieure est trop grande par -rapport au diamètre des billes, l'assemblage du roulement devient difficile. Par conséquent, lorsque l'on tient compte de l'assemblage du roulement, les profondeurs des gorges des pool. However, if the sum of the depths of the grooves of the outer and inner rings is too large in relation to the diameter of the balls, the assembly of the bearing becomes difficult. Therefore, when bearing assembly is considered, the depths of the grooves of

faire la relation h + h < 0,75d. Si la somme h1 + h2 des profondeurs des gorges dépasse 0,75d, il est nécessaire de ménager, dans l'épaulement de la gorge de la bague extérieure ou de la bague intérieure, une encoche d'introduction des billes, et de refermer cette encoche après que les billes ont été mises en place, ce qui, non seulement, rend l'assemblage du roulement difficile, mais également n'est pas souhaitable make the relation h + h <0.75d. If the sum h1 + h2 of the depths of the grooves exceeds 0.75d, it is necessary to arrange, in the shoulder of the groove of the outer ring or the inner ring, a notch for introducing the balls, and to close this notch after the balls have been put in place, which not only makes the bearing assembly difficult, but also is not desirable

ment. L'invention sera décrite plus en détail en regard du dessin annexé à titre d'exemple nullement limitatif et sur lequel: - la figure 1 est une coupe longitudinale partielle d'une forme de réalisation du roulement à billes à gorges profondes selon l'invention; et - la figure 2 est une coupe longitudinale is lying. The invention will be described in more detail with reference to the accompanying drawings by way of non-limiting example and in which: - Figure 1 is a partial longitudinal section of an embodiment of the deep groove ball bearing according to the invention ; and - Figure 2 is a longitudinal section
montrant l'assemblage des bagues et d'une bille. showing the assembly of the rings and a ball.
Les figures 1 et 2 représentent une forme préférée de réalisation de l'invention. Ce roulement à billes à gorges profondes comporte une bagué extérieure 1, une bague intérieure 2, des billes 3, un organe 4 de retenue et un Figures 1 and 2 show a preferred embodiment of the invention. This deep groove ball bearing comprises an outer ring 1, an inner ring 2, balls 3, a retaining member 4 and a
joint 5.attached 5.
La bague extérieure 1 présente une piste incurvée 11 à gorge profonde. La profondeur hî de la gorge de la piste incurvée 11 est légèrement supérieure à la moitié (d/4) du demi-diamètre (rayon) de la bille dont le diamètre est d, et la profondeur h2 de la gorge de la piste incurvée de la bague intérieure 2 est également légèrement supérieure au quart du diamètre de la bille 3. Autrement dit, la somme (h + h12) de la profondeur de la gorge de la piste de la bague extérieure The outer ring 1 has a curved, deep groove track 11. The depth h 1 of the groove of the curved track 11 is slightly greater than half (d / 4) of the half-diameter (radius) of the ball whose diameter is d, and the depth h 2 of the groove of the curved track of the inner ring 2 is also slightly greater than a quarter of the diameter of the ball 3. In other words, the sum (h + h12) of the depth of the groove of the track of the outer ring
et de la profondeur de la gorge de la piste de la bague inté- and the depth of the groove of the track of the inner ring.
rieure est plus grande que la moitié (d/2) du diamètre d de la bille 3. En particulier, dans la forme de réalisation is greater than half (d / 2) of the diameter d of the ball 3. In particular, in the embodiment
décrite, hî et-h 2 ont une relation telle que hi < h2. described, h 1 and h 2 have a relationship such that hi <h 2.
En ce qui concerne la bague extérieure 1 et la bague intérieure 2 ainsi réalisées, comme montré sur la figure 2, par exemple, la bague intérieure 2 est inclinée par rapport à la bague extérieure 1 d'un côté de laquelle elle est approchée; l'épaulement de la gorge de la bague intérieure 2 est approché ou mis au contact de la partie à peu près centrale du fond de la gorge de la bague extérieure 1 afin de former, sur l'autre côté, l'intervalle e nécessaire à la mise en place des billes; le nombre nécessaire de billes 3 est introduit par cet intervalle; les billes 3 mises en place sont disposées à peu près à égale distance les unes des autres entre les pistes des bagues extérieure et intérieure; puis l'organe 4 de retenue est monté sur les bagues extérieure et intérieure, de manière à constituer le As regards the outer ring 1 and the inner ring 2 thus produced, as shown in Figure 2, for example, the inner ring 2 is inclined relative to the outer ring 1 on one side of which it is approached; the shoulder of the groove of the inner ring 2 is approached or brought into contact with the approximately central part of the bottom of the groove of the outer ring 1 in order to form, on the other side, the gap e necessary to the placement of the logs; the necessary number of balls 3 is introduced through this interval; the balls 3 put in place are arranged approximately equidistant from each other between the tracks of the outer and inner rings; then the retaining member 4 is mounted on the outer and inner rings, so as to constitute the

Un essai effectué sur trois types de roulement, c'est-à-dire un roulement dans lequel h1 est égal à 26 % de d et h2 est égal à 28 % de d, un roulement dans lequel h1 est égal à 29 % de d et h2 est égal à 34 % de d, et un roulement dans lequel h1 est égal à 32 % de d et h2 est égal à 40 % de d, a montré que l'accroissement de la profondeur des gorges, compte tenu de la relation de montage, permet d'accroître efficacement la durée de vie du roulement, et qu'une somme des profondeurs des gorges dépassant 60 % de d est plus efficace qu'une somme inférieure à 60 % et multiplie par dix A test carried out on three types of bearings, that is to say a bearing in which h1 is equal to 26% of d and h2, is equal to 28% of d, a bearing in which h1 is equal to 29% of d and h2 is equal to 34% of d, and a turnover in which h1 is equal to 32% of d and h2 is equal to 40% of d, showed that the increase in depth of the grooves, given the relationship mounting time, and that a sum of groove depths exceeding 60% of d is more effective than a sum of less than 60% and multiplies by ten
la durée de vie des roulements classiques. the life of conventional bearings.
Bien que l'invention ait été décrite sous la forme d'un exemple de roulement à billes à gorges profondes de type normal, l'invention s'applique également, par exemple, aux roulements comportant des brides de- montage situées sur la bague extérieure et sur la bague intérieure, aux roulements destinés à être associés à des pièces de machine dans une partie desquelles des pistes de roulement sont réalisées, ou bien aux roulements à billes du type complet, sans organe de retenue. En particulier, lorsque l'invention est appliquée à ce dernier type de roulement, des trous ou des rainures d'introduction des billes sont réalisés dans la bague extérieure ou dans la bague intérieure ou dans les deux bagues pour permettre l'assemblage de la bague extérieure, de la bague intérieure et des billes. Il est parfois possible de réaliser le roulement selon l'invention *de manière que la profondeur de la gorge de la bague intérieure soit égale à la profondeur de la gorge de la bague extérieure et, en outre, la piste incurvée précitée peut être réalisée sous la forme d'une surface courbe à rayon unique, légèrement supérieur au rayon des billes, ou bien sous la forme d'une surface quadrique ayant une courbure- qui varie progressivement du fond de la gorge vers l'épaulement. Par conséquent, la forme de la courbure de la surface de la gorge Although the invention has been described in the form of an example of deep-groove ball bearing of normal type, the invention is also applicable, for example, to bearings having mounting flanges located on the outer ring. and on the inner race, bearings intended to be associated with machine parts in a part of which rolling tracks are made, or else to ball bearings of the complete type, without retainer. In particular, when the invention is applied to the latter type of bearing, holes or grooves for introducing the balls are made in the outer ring or in the inner ring or in the two rings to allow the assembly of the ring. outer ring, inner ring and balls. It is sometimes possible to make the bearing according to the invention * so that the depth of the groove of the inner ring is equal to the depth of the groove of the outer ring and, in addition, the curved track mentioned above can be performed under the shape of a curved surface with a single radius, slightly greater than the radius of the balls, or in the form of a quadric surface having a curvature which varies gradually from the bottom of the groove to the shoulder. Therefore, the shape of the curvature of the surface of the throat
n'est pas particulièrement limitée. is not particularly limited.
De plus, lorsque les bagues intérieure et extérieure sont assemblées excentriquement l'une par rapport à l'autre de manière que leurs épaulements pénètrent dans leurs gorges correspondantes et respectives,comme montré sur la figure 2, les profondeurs des gorges peuvent être portées à des valeurs telles que la plus grande des deux sommes In addition, when the inner and outer rings are eccentrically joined relative to one another so that their shoulders penetrate their respective corresponding grooves, as shown in FIG. 2, the depths of the grooves can be brought to values such as the larger of the two sums
2h2 + h1 et 2h1 + h2 soit à peu près égale à 1,13d. 2h2 + h1 and 2h1 + h2 is roughly equal to 1.13d.
Il va de soi que de nombreuses modifications peuvent être apportées au roulement à billes décrit et It goes without saying that many modifications can be made to the described ball bearing and
