CA 2220214

The linear guide device of the present invention has a structure in which a solid lubricating film is applied on the ball guide grooves of the main rail and the ball circulating paths of the slider, and the surfaces of the balls housed to be rotatable and movable in the ball circulating paths, are formed porous. Thus, when the slider is urged to move with respect to the main rail, and the balls rotate and move within the ball circulating paths, the balls are brought into contact with the solid lubricating films on the ball circulating paths and the films on the ball guide grooves of the main rail. Due to the effect of the surfaces of the balls, the solid lubricating film is transferred onto the surfaces of the balls, thus achieving solid lubrication.

Le dispositif de guidage linéaire de la présente invention possède une structure dans laquelle un film lubrifiant solide est appliqué sur les rainures de guidage des billes du rail principal et les chemins de roulement des billes de la partie coulissante, et où les surfaces des billes placées de manière à pouvoir tourner et à se déplacer dans leurs chemins de roulement sont poreuses. De cette façon, lorsque la partie coulissante est forcée de bouger par rapport au rail principal, et que les billes tournent et se déplacent à l'intérieur de leurs chemins de roulement, elles sont mises en contact avec les films lubrifiants solides dans les chemins de roulement et les films sur les rainures de guidage des billes du rail principal. Par l'effet des surfaces des billes, le film lubrifiant solide est transféré sur ces dernières, et il y a alors lubrification solide.
