ROLLING GUIDE DEVICE AND DRIVE SYSTEM USING ROLLING GUIDE DEVICE

摘要

PURPOSE: A rolling guide device and drive system using rolling guide device is provided to take a large expansion/contraction stroke and sufficiently bearing moment load, radial load and thrust load at any expanded(contracted) attitude. CONSTITUTION: A rolling guide device comprises a track rail(7) formed with a rolling member rolling surface(11) extending along a longitudinal direction thereof; a movable rail(8) formed with a loaded rolling member rolling surface(15) extending along a longitudinal direction thereof so as to oppose to the rolling member rolling surface of the track rail; a track rail side rolling member circulation passage(14) formed to the track rail so as to circulate the rolling members rolling between the track rail and the movable rail; a movable rail side rolling member circulation passage(16) formed to the movable rail so as to circulate the rolling members rolling between the track rail and the movable rail; and a number of rolling members(12,13) disposed and arranged in the track rail side rolling member circulation passage and the movable rail side rolling member circulation passage.
