Abstract

L’invention a pour but de résoudre les problèmes posés par les éléments coulissants conventionnels qui doivent être grands et qui nécessitent un cycle de maintenance court pour lubrifier la surface coulissante au moyen de douilles et de paliers comportant des rainures de graissage. Dans la broche coulissante (1), des rainures annulaires (11) sont formées dans la surface latérale de celle-ci et une matière de résine anti-frottement (12) est incorporée dans les rainures annulaires (11). L’adhérence de la matière de résine anti-frottement (12) sur les surfaces latérales et les surfaces de fond des rainures (11) est améliorée car elle contient de l’huile ou une poudre particulaire (13). En outre, la matière de résine anti-frottement (12) dans le voisinage de l’ouverture de la rainure (11) crée une forme poreuse qui constitue une structure qui retient facilement l’huile à l’intérieur de la matière de résine anti-frottement (12), la lubrification de la surface coulissante étant de ce fait améliorée.
