LINEAR MOTION GUIDING UNIT, CAPABLE OF SMOOTH STRAIGHT MOTION GUIDE AND LOAD SUPPLY WITHOUT THE DECREASE OF ROLLERS

摘要

PURPOSE: A linear motion guiding unit is provided to prevent the location change due to the sliding motion of a roller cage assembly between first and second guide rails.;CONSTITUTION: A linear motion guiding unit comprises first and second guide rails(110,120) and a roller cage assembly(130). The track units(115,125) of the first and second guide rails are formed in a concave shape having a V-shaped section. The roller cage assembly is located between the first and second guide rails. The roller cage assembly is composed of a plurality of rollers(135), a cage board(145), and a pinion(155). A plurality of roller mounting holes of the cage board rotatably restricts each roller. The cage board is located between the first and second guide rails. One side of the width direction of the pinion is mesh with the first guide rail. The other side of the pinion is meshed with the second guide rail.;COPYRIGHT KIPO 2011
