Title:
LINEAR MOTION GUIDE UNIT
Document Type and Number:
WIPO Patent Application WO/2011/093505
Kind Code:
A1
Abstract:
Provided is a linear motion guide unit which comprises: two rods (31a, 31b) which are formed facing side surfaces where two mutually parallel linear V-shaped grooves face each other; and a holding plate (16) which holds three or more cylindrical rollers accommodated in each of guide paths (13H, 13L) formed by said opposing linear V-shaped grooves. (1) All of the rollers in guide path (13L) are arranged with the central axes thereof being mutually oriented toward the same direction, and (2) at least one of the rollers from among the rollers in guide path (13H) is arranged so that the central axis thereof is oriented toward the same direction as the central axes of the rollers of (1) above, and at least two other rollers are arranged so as to be oriented toward a direction intersecting the direction of the central axes of the rollers of (1) above and to not be adjacent to each other. Load applied to the rods is dispersed to the rollers accommodated in the guide paths, and excessive wear on one of the linear V-shaped grooves of the guide paths is therefore suppressed, resulting in excellent durability.
