(EN) THRUST WASHER
(FR) RONDELLE DE BUTÉE
(JA) スラストワッシャ
Abstract
(EN)
Provided is a thrust washer that exhibits excellent heat resistance, ductility, low friction properties and abrasion resistance. A thrust washer 1 is obtained by molding a resin composition. The resin composition contains, as a base resin, a polyamide resin comprising a dicarboxylic acid component and a diamine component, and the resin composition is obtained by blending a fibrous reinforcing material with the base resin. The dicarboxylic acid component contains mainly terephthalic acid, the diamine component contains mainly 1,9-nonanediamine or 1,10-decanediamine, and the fibrous reinforcing material is at least one type selected from among glass fibers and carbon fibers and is contained at a quantity of not less than 10 mass % but less than 60 mass % relative to the overall resin composition.

L'invention concerne une rondelle de butée qui présente une excellente résistance à la chaleur, une ductilité, des propriétés de faible frottement et une résistance à l'abrasion. Une rondelle de butée 1 est obtenue par moulage d'une composition de résine. La composition de résine contient, en tant que résine de base, une résine de polyamide comprenant un composant acide dicarboxylique et un composant diamine, et la composition de résine est obtenue par mélange d'un matériau de renfort fibreux avec la résine de base. Le composant acide dicarboxylique contient principalement de l'acide téréphtalique, le composant diamine contient principalement 1,9-nonanediamine ou 1,10-décanediamine, et le matériau de renfort fibreux est au moins un type choisi parmi des fibres de verre et des fibres de carbone et est contenu en une quantité supérieure ou égale à 10 % en masse mais inférieure à 60 % en masse par rapport à la composition de résine globale.
