Title:
ROLLING GUIDE DEVICE AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/004488
Kind Code:
A1
Abstract:
A rolling guide device easily manufacturable at low cost by reducing the number
of parts forming a slide member (2) and reducing man-hours for machining the slide
member. The rolling guide device comprises a track rail (1) and the slide member
(2) installed on the track rail (1) through a large number of balls (3). The slide
member (2) is formed in a channel shape by bending a metal plate member (5) so as
to have a lateral web (20) and a pair of flange parts (21). A track groove (30) for
circulating the balls (3) therein is formed in each of the flange parts (21). The
track groove (30) comprises a load straight groove (31) in which the balls (3)
roll while carrying a load, a pair of ball deflecting grooves (34) changing the
direction of the balls (3) rollingly moved in the load straight groove (31) while
removing the load from the balls, and a no-load straight groove (34) feeding the
balls (3) from one ball deflecting groove (34) to the other ball deflecting groove.
