Description

reculement comportant au moins une bague fractionnes et une liaison d assemblage. recess comprising at least one split ring and an assembly link.

L inventi on concerne un roulement comportant au molns une bague fractionnée et une liaison d'assemblage. The invention relates to a bearing comprising at the molns a split ring and an assembly connection.

6ur cr type de roue ment une bague d assemb age en matériau elastique est habituellement emmanchée dans l'alesage des deux bagues intérieures et/ou sur le diamètre extérieur des deu bagues extérieures et permet leur liaison pendant le transport et les opérations de manutention avant montage. Cette bague d-assemblage est généralement chassée au montage lors de iem- manchement des bagues intérieures sur un arbre ou des bagues extérieures dans un alésage. Au cours du démontage du roulement. With a type of wheel, an assembly ring of elastic material is usually fitted into the bore of the two inner rings and / or the outer diameter of the two outer rings and allows their connection during transport and handling operations before assembly. . This assembly ring is generally driven to assembly when iem- nagement of the inner rings on a shaft or outer rings in a bore. During the dismantling of the bearing.

lors d-une intervention d'entretien, les deux bajoues intérieures sont désolidarisées. Il s'ensuit un risque de mélange des pièces ainsi qu'une possibilité de pollution des parties inter- nes du roulement.during a maintenance intervention, the two inner jowls are disconnected. This results in a risk of mixing of the parts as well as a possibility of pollution of the internal parts of the bearing.

Lut emploi de clips élastiques peut également nécessiter des opérations d'usinage supplémentaire sans rapport avec le bon fonctionnement du roulement. The use of elastic clips may also require additional machining operations unrelated to the proper operation of the bearing.

La differenciation dimensionnelle des roulements nécessite également la realisation de séries de pièces d'assemblage, une gestion quantitative et des mesures de recyclage
L'invention a pour but de remédier à ceE inconvénients. Elle a donc pour objet une liaison des bagues intérieures et/ou extérieures integree au roulement dans le but de rendre les éléments du roulement inséparables pendant les opérations de transport, de manutentions, de montage et de demontage, c'est-a- dire pendant toute la durée de vie du roulement.The dimensional differentiation of the bearings also requires the realization of series of assembly parts, quantitative management and recycling measures
The object of the invention is to overcome these disadvantages. It therefore relates to a connection of the inner and / or outer rings integrated in the bearing in order to make the bearing elements inseparable during transport, handling, assembly and disassembly, that is to say during the entire life of the bearing.

L'invention a également pour objet une liaison fusible des bagues intérieures et/ou extérieures notamment sous l'effet d'efforts engendrés par des percussions ou chocs dans le but de détecter visuellement les roulements impropres b l'usage. The subject of the invention is also a fusible connection of the inner and / or outer rings, in particular under the effect of forces generated by percussions or shocks in order to visually detect the bearings that are unfit for use.

Selon l'invention la liaison est constituée par un film d colle d épaisseur inférieure à 60 microns situé entre les deux parties de la bague au contact des surfaces rectifiées de rugo sité a comprise entre 0.2 et 0.5 micron . Dans le roulement ainsi assemble la liaison des élements de la bague peut étre assures pour des efforts mic en jeu pendant le transport. la manutention ou l'extraction du roulement.La liaison mettra avantageusement en oeuvre des col les du type anaérobie, cyanoa- crylate ou des adhésifs instantanés, connues par leurs caractéristique mécaniques:
- résistance à la traction jusqu'à 45 N/mm2
- tempereture admissible - 55u à + 125 C
- résistance aux chocs jusqu'à 3,5 N.mm/mm
- résistance au cisaillement jusqu'à 25 N/mm
D'autres caractéristiques et avantages de l'invention appa raieront a la lecture de la description faite en référence au dessin annexe dans lequel les figures 1 å 10 sont des reprEsen- tations schématiques de roulements montrant divers agencements de bagues et de corps roulants qui font application dune liaison collée entre deux parties d une me me bague.According to the invention, the bond is constituted by a glue film with a thickness of less than 60 microns located between the two parts of the ring in contact with the ground surfaces of roughness between 0.2 and 0.5 micron. In the bearing thus assembled the connection of the elements of the ring can be ensured for mic efforts in play during transport. The bonding will advantageously employ anaerobic type, cyanoacrylate or instant adhesive adhesives, known by their mechanical characteristics:
- tensile strength up to 45 N / mm2
- admissible temperure - 55u to + 125 C
- impact resistance up to 3.5 Nm / mm
- shear strength up to 25 N / mm
