Linear motion guide device

Abstract

A linear motion guide device allowed to be manufactured easily in a large size and capable of preventing long and thin-walled holding members and relief passage component members from being deformed and inner peripheral guide part component members from being opened, wherein holding members (11, 12, 13) extending along both side edges of load roller rolling surfaces and preventing rollers from falling down from the load roller rolling surfaces when a moving block (2) is removed from a track rail (1), relief passage component members (14, 14) forming a roller relief passage, and inner peripheral guide part component members (15a, 15b) forming the inner peripheral guide part for directional change are formed of a resin separately from a block main body (4) and separately from each other and assembled into the block main body (4), whereby the amount of shrinkage of each of the holding members (11, 12, 13), relief passage component members (14, 14), and inner peripheral guide part component members (15a, 15b) can be calculated before production, and thus the long and thin-walled holding members (11, 12, 13) and relief passage component members (14, 14) can be prevented from being deformed and the inner peripheral guide part component members (15a, 15b) can be prevented from being opened.

Description

technical field [0001] The present invention relates to a motion guide equipped with a movable member having a main body in which a channel forming member formed of a resin material is assembled. Background technique [0002] There is a motion guide device that is equipped with a guide rail on which a rolling member rolling portion is formed, and a movable unit is provided that can move along the track through a plurality of rolling members such as balls and rollers. The movable assembly includes a loaded rolling element rolling part corresponding to the rolling part of the track rolling element; a rolling element escape channel formed by separating a predetermined gap in parallel with the loaded rolling element rolling part; a pair of rolling element rolling direction Changing channels, each of which is interconnected with the rolling part of the loaded rolling element and with the rolling element escape channel, constitutes a rolling element circulating channel for circula...

AI Technical Summary

Problems solved by technology

Therefore, when the connecting part of the supporting member, the escape channel forming part and the inner peripheral guide part forming part is integrally formed, the thin and long supporting part and the escape channel forming part may be bent, and the inner peripheral guiding part constitutes files may be left open, which poses another problem
