Abstract

L'invention concerne une chaîne (1) pour un entraînement à chaîne d'une pompe à huile. La chaîne comprend une pluralité de brides extérieures et intérieures (2, 3) qui sont reliées les unes aux autres de manière à pouvoir pivoter par l'intermédiaire d'éléments de liaison (4) cylindriques. La bride extérieure respective et la bride intérieure respective (2, 3) comportent respectivement un premier et un deuxième alésage (5, 6) servant à recevoir et à faire passer axialement l'élément de liaison (4) respectif. Le premier alésage (5) de la bride extérieure respective et de la bride intérieure respective (2, 3) présente un ajustement serré sur l'élément de liaison (4). Le deuxième alésage (6) de la bride extérieure respective et de la bride intérieure respective (2, 3) présente un ajustement glissant sur l'élément de liaison (4).
