LINEAR SLIDE RAIL HAVING THE EXTENDABLE LIFE CYCLE

摘要

Provides a linear slide rail for extended service life. The present invention is a linear slide rail that can extend the service life, and includes a guide rail, a slide block, and a plurality of rolling pillar units, and a plurality of rolling pillar accommodation holes are provided between the guide rail and the slide block, and each The rolling pillar receiving hole is composed of two V-shaped grooves jointly, and each V-shaped groove has two inclined surfaces, and the rolling pillars of the rolling pillar unit are in linear contact with one of the inclined surfaces, and the inclined surfaces are After being worn, the rolling posts can be rolled into line contact by selecting another unweared inclined surface, thereby achieving the effect of doubling the service life, and also having different lengths at both ends of the rolling posts in the middle line. 1st and 2nd cross section is provided, and the contact line position of a rolling post and a V-shaped groove inner wall by selecting another cross section and inserting it into a rolling post receiving hole. It can achieve the effect of doubling the service life of the linear slide rail by generating the variation movement.
