Title
(EN) SMALL REDUCTION GEAR
(FR) ENGRENAGE RÉDUCTEUR DE PETITE TAILLE
(JA) 小型減速機
Abstract
(EN)
A small reduction gear 1 includes an input gear 33, a first planetary carrier 42, and a first planetary gear 44 which are formed by a molded body of a resin composition containing, in a base resin, an inorganic whisker that serves as a functional expression component, the combined content of the base resin and the inorganic whisker in the resin composition being 99.5% by weight or more. Or, the foregoing are formed by a molded body of a resin composition containing an inorganic whisker and a lubricant that serve as functional expression components in a base resin, the combined content of the base resin, the inorganic whisker, and the lubricant in the resin composition being 99.5% by weight or more, and the content of the lubricant being 1% by weight or more. The input gear 33 and the first planetary carrier 42, or the input gear 33 and the first planetary gear 44, are formed by the same material, and the first planetary gear 33 and the first planetary carrier 42 are formed by different materials.

Un engrenage réducteur de petite taille (1) comprend un engrenage d'entrée (33), un premier porte-satellite (42) et un premier satellite (44) qui sont formés au moyen d'un corps moulé d'une composition de résine contenant, dans une résine de base, une barbe inorganique qui sert de composant d'expression fonctionnel, la teneur combinée de la résine de base et de la barbe inorganique dans la composition de résine étant de 99,5 % en poids ou plus. Ou bien, les éléments précédents sont formés au moyen d'un corps moulé d'une composition de résine contenant une barbe inorganique et un lubrifiant qui servent de composants d'expression fonctionnels dans une résine de base, le contenu combiné de la résine de base, de la barbe inorganique et du lubrifiant dans la composition de résine étant de 99,5 % en poids ou plus, et la teneur en lubrifiant étant de 1 % en poids ou plus. L'engrenage d'entrée (33) et le premier porte-satellite (42), ou l'engrenage d'entrée (33) et le premier satellite (44), sont constitués du même matériau, et le premier satellite (33) et le premier porte-satellite (42) sont constitués de différents matériaux.
