Description
-1- DISPOSITIF POUR LE BLOCAGE D'UN PALIER SUR UN ARBRE DESCRIPTION-1- DEVICE FOR BLOCKING A BEARING ON A TREE DESCRIPTION
DOMAINE DE L'INVENTION La présente invention concerne un dispositif destiné à permettre la solidarisation et la désolirdarisation aisée d'un palier lisse ou à roulement sur un arbre, ledit palier pouvant être fixé à une paroi, ou flasque, d'une pompe notamment alimentaire. FIELD OF THE INVENTION The present invention relates to a device intended to allow the easy joining and desolirdarisation of a plain or rolling bearing on a shaft, said bearing being able to be fixed to a wall, or flange, of a particular food pump. .
ARRIERE PLAN TECHNOLOGIQUE Dans la pratique courante, les paliers à roulement sont emmanchés en force sur les arbres nécessitant pour leur démontage des moyens particuliers, tels des arraches moyeux, avec pour conséquence des difficultés de démontage et des risques de grippage. BACKGROUND TECHNOLOGY In the current practice, the rolling bearings are force-fitted on the shafts requiring, for their disassembly, special means, such as hub disengagement, with the consequent difficulty of disassembly and the risk of seizing.
Ce problème se pose avec d'autant plus d'acuité lorsqu'il s'agit d'équipements, tels des pompes à usage alimentaire, où, pour des raisons d'hygiène, leur démontage et leur remontage doit être effectué fréquemment. Une solution connue consiste à placer les deux paliers du même coté, à l'arrière du rotor, créant ainsi un porte-à-faux sur la partie avant avec pour conséquence, un encombrement beaucoup plus important ainsi que des risques pouvant résulter de tout dispositif en porte-à-faux. Une autre solution connue (brevet BE665412) consiste à utiliser des bagues cintrées, en acier, dont l'élasticité est obtenue par des trous et l'adhérence par des saillies agissant par clavetage par pénétration dans les parois en regard. De tels dispositifs, outre la technicité nécessaire à la réalisation des bagues, ne permettent par des démontages fréquents et finissent par se détériorer et détériorer les surfaces en contact avec dégradation rapide du pouvoir de serrage. Des dispositifs similaires sont également décrits dans les brevets DE10309787, DE916370 et EP0748944. This problem is all the more acute when it comes to equipment, such as food pumps, where, for reasons of hygiene, dismantling and reassembly must be performed frequently. A known solution is to place the two bearings on the same side, at the rear of the rotor, thus creating a cantilever on the front part with the consequence of a much larger size and risks that may result from any device cantilevered. Another known solution (patent BE665412) consists of using bent rings made of steel, the elasticity of which is obtained by holes and the adhesion by projections acting by keying by penetration into the opposite walls. Such devices, in addition to the technicality necessary for producing the rings, do not allow frequent disassembly and eventually deteriorate and damage the surfaces in contact with rapid degradation of the clamping power. Similar devices are also described in DE10309787, DE916370 and EP0748944.
RESUME DE L'INVENTION L'invention vise à mettre en oeuvre un dispositif, de conception simple, facile à utiliser, conservant ses performances dans le temps et ce quelque soit le nombre et la fréquence des démontages, ne détériorant pas les surfaces en contact, autrement dit supprimant les inconvénients susmentionnés. SUMMARY OF THE INVENTION The invention aims to implement a device of simple design, easy to use, maintaining its performance over time and whatever the number and frequency of disassembly, does not deteriorate the surfaces in contact, in other words, eliminating the aforementioned drawbacks.
Le dispositif selon l'invention est du type constitué : a) d'un manchon déformable apte à être intercalé entre une partie de la bague intérieure dudit roulement et une partie de l'extrémité dudit arbre ; b) d'un nez de blocage pourvu d'une bague cylindrique apte à se loger dans l'espace libre existant entre le manchon déformable, l'autre partie de la bague intérieure dudit roulement et l'autre partie de l'extrémité dudit arbre et à se déplacer dans ledit espace, sous l'effet d'une pression exercée axialement sur celle-ci, de manière à comprimer ledit manchon déformable jusqu'à l'obtention du blocage de l'arbre sur la bague intérieure du roulement. Il se caractérise essentiellement, en ce que le manchon déformable est totalement cylindrique et possède des parois interne et externe lisses, en ce que son épaisseur au repos est légèrement inférieure à l'espace compris entre l'extérieur de l'arbre et l'intérieur du roulement ou du palier lisse et en ce qu'il est réalisé en élastomère. Un tel dispositif permet un démontage et un remontage aisé du palier par simple dévissage ou revissage (quelques tours seulement) de l'écrou, autant de fois que nécessaire et ce sans le moindre effort: ni risque de grippage ou de détérioration de la jonction arbre et palier puisque la rnatière une fois décompressée, reprend son épaisseur initiale. PRESENTATION DES FIGURES Les caractéristiques et les avantages de l'invention vont apparaître plus clairement à la lecture de la description détaillée qui suit d'au moins un rnode de réalisation préféré de celle-ci donné à titre d'exemple non limitatif et représenté aux dessins annexés. The device according to the invention is of the type consisting of: a) a deformable sleeve capable of being interposed between a portion of the inner ring of said bearing and a portion of the end of said shaft; b) a locking nose provided with a cylindrical ring adapted to be housed in the free space existing between the deformable sleeve, the other part of the inner ring of said bearing and the other part of the end of said shaft and to move in said space, under the effect of a pressure exerted axially thereon, so as to compress said deformable sleeve until the locking of the shaft on the inner ring of the bearing. It is essentially characterized in that the deformable sleeve is completely cylindrical and has smooth inner and outer walls, in that its thickness at rest is slightly less than the space between the outside of the shaft and the inside. of the bearing or plain bearing and in that it is made of elastomer. Such a device allows easy disassembly and reassembly of the bearing by simply unscrewing or screwing (a few turns only) of the nut, as many times as necessary and without the slightest effort: no risk of seizing or deterioration of the shaft junction and bearing since the material once decompressed, resumes its initial thickness. PRESENTATION OF THE FIGURES The characteristics and advantages of the invention will appear more clearly on reading the detailed description which follows of at least one preferred embodiment thereof given by way of non-limiting example and shown in the drawings. attached.
