Title (EN) LUBRICATING CAP, FASTENER COMPRISING THIS TYPE OF CAP AND INTERFERENCE ASSEMBLY PROCESS
(FR) CAPUCHON DE LUBRIFICATION, ÉLÉMENT DE FIXATION COMPRENANT CE TYPE DE CAPUCHON ET PROCÉDÉ D'ASSEMBLAGE AVEC INTERFÉRENCE
Abstract:
(EN) The object of the invention is a cap to lubricate an inner wall of a perforation going through at least two elements of the structure. The cap comprises a tubular body and at least one lubricant reserve, and before installation in the structure said cap has a largest external diameter larger than an internal diameter (DS) of the perforation, and the cap lubricates the internal surface of the perforation when its largest external diameter is radially compressed by a wall of the perforation. The invention also concerns a fastener comprising this type of cap, and an interference assembly process for the fastener equipped with the cap. The invention is applicable to the assembly of aircraft structures.
(FR) La présente invention concerne un capuchon permettant de lubrifier une paroi interne d'une perforation traversant au moins deux éléments de la structure. Le capuchon comprend un corps tubulaire et au moins une réserve de lubrifiant, et avant installation dans la structure, ledit capuchon a un diamètre externe le plus grand supérieur à un diamètre interne (DS) de la perforation, et le capuchon lubrifie la surface interne de la perforation lorsque son plus grand diamètre externe est radialement comprimé par une paroi de la perforation. L'invention concerne également un élément de fixation comprenant ce type de capuchon, et un procédé d'assemblage avec interférence destiné à l'élément de fixation équipé du capuchon. L'invention est applicable à l'assemblage de structures d'aéronefs.
