Title:
LINEAR GUIDE DEVICE WITH OFFSET-LOAD PREVENTION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2005/010384
Kind Code:
A1
Abstract:
A linear guide device where, even when an offset load is applied to rollers rolling in a load rolling path, the offset load can be effectively reduced and the movement of a slider relative to a raceway rail can be smoothened, and wear of the rollers can be prevented as far as possible. In the linear guide device, a bearing race with a load rolling surface where rollers roll is provided, and a reception groove where the bearing race is fitted is provided on the slider, at a position opposed to a raceway rail-side rolling surface. The bearing race and the reception groove are formed in a substantially semi-circular cross-section in the direction orthogonal to the rolling direction of the rollers. The bearing race is structured so as to be oscillatable in the reception groove with the outer peripheral surface of the bearing race in sliding contact with the inner peripheral surface of the reception groove. The center of the oscillation of the bearing race in the reception groove is positioned between the raceway rail-side rolling surface and the slider-side load rolling surface that are opposed to each other.
