Abstract
Un dispositivo de guia para miembros mecánicos, que consta de dos partes diseñadas para interactura mediante fricción por deslizamiento, una de las dos partes, llamada la parte lisa, tiene una superficie funcional lisa, es decir de fricción, y la otra parte, llamada la parte perforada, tiene por lo menos una superficie funcional, es decir de fricción que incluye cavidades emergentes diseñadas para acomodar una grasa del tipo de pasta de lubricante y especialmente una grasa EP (grasa de presión extrema) que contiene un constituyente de tipo de jabón, un constituyente de tipo aceite y un aditivo de presión extrema caracterizado porque el ángulo de contacto 0 entre la superficie funcional de la parte lisa y la grasa es entre 20 y 40 grados y porque el material de la parte perforada se escoge de tal manera que el ángulo de contacto entre la superficie funcional de la parte perforada y la grasa es entre 45 y 75 grados, el dispositivo de la invención puede ser del tipo de vía de deslizamiento/superficie de rodamiento, tipo de flecha/cojinete, tipo de articulación de bola/receptáculo, etc.A guide device for mechanical members, consisting of two parts designed to interact by sliding friction, one of the two parts, called the smooth part, has a smooth functional surface, that is to say, friction, and the other part, called the perforated part, has at least one functional, i.e. friction surface including emerging cavities designed to accommodate a lubricating paste type grease and especially an EP (extreme pressure grease) grease containing a soap type constituent, an oil-type constituent and an extreme pressure additive characterized in that the contact angle 0 between the functional surface of the smooth part and the grease is between 20 and 40 degrees and that the material of the perforated part is chosen in such a way that the contact angle between the functional surface of the perforated part and the grease is between 45 and 75 degrees, the device of the invention can be of the slip / bearing surface, arrow / bearing type, ball / socket joint type, etc.
