Title:
MOVEMENT GUIDE DEVICE AND ROLLING ELEMENT USED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2007/026702
Kind Code:
A1
Abstract:
A non-magnetized, highly corrosive-resistant, and lightweight linear guide device
(40), wherein balls (42) forming the linear guide device (40) are formed of a superelastic
material and a track rail (41) and a moving block (43) are formed of a nonmagnetic
material such as a ceramics. The track rail (41) and the moving block (43) receiving
rolling and sliding loads from the balls (42) can be formed of a material with a
thin hard layer by forming the balls (42) of the superelastic material. Furthermore,
since the track rail (41) and the moving block (43) can be machined with a rough
machining accuracy by forming the balls (42) of the superelastic material, the
manufacturing cost of the linear guide device (40) can be reduced. By realizing
the linear guide device (40) having these working effects, the scope of application
of the movement guide device can be increased.
