Title (EN) BEARING MATERIAL, BEARING AND METHOD
(FR) MATÉRIAU DE PALIER, PALIER ET PROCÉDÉ
Abstract:
(EN) In a bearing element, for a sliding journal bearing such as a crankshaft main bearing, a bearing shell 4 supports a sliding layer, or overlay, 12. The overlay is formed from a bearing material of a polyamide-imide (PAI) plastics polymer material functionalised with hydrocarbon groups. A method for making the bearing material includes the steps of preparing a polyamide-imide polymer material; and when the resulting polymer material reaches a predetermined molecular weight, adding a hydrocarbon-containing reactant to the reaction mixture to form a bearing material comprising a polyamide-imide plastics polymer material functionalised with hydrocarbon groups with reactive functionality. Another method for making the bearing material involves mixing a polyamide-imide plastics polymer with a catalyst; and adding a hydrocarbon-containing reactant to the reaction mixture.
(FR) Dans un élément de palier, pour un palier lisse coulissant tel qu'un palier principal de vilebrequin, une coque 4 de palier supporte une couche de coulissement, ou un revêtement, 12. Le revêtement est formé à partir d'un matériau de palier d'un matériau polymère plastique de polyamide-imide (PAI) fonctionnalisé avec des groupes hydrocarbonés. Un procédé de fabrication du matériau de palier comprend les étapes de préparation d'un matériau polymère de polyamide-imide ; et lorsque le matériau polymère obtenu atteint un poids moléculaire prédéfini, d'ajout d'un réactif contenant des hydrocarbures au mélange de réaction pour former un matériau de palier comprenant un matériau polymère plastique de polyamide-imide fonctionnalisé avec des groupes hydrocarbonés ayant une fonctionnalité réactive. Un autre procédé de fabrication du matériau de palier consistant à mélanger un polymère plastique de polyamide-imide avec un catalyseur ; et à ajouter un réactif contenant des hydrocarbures au mélange de réaction.
