Title:
BEARING, PRECESSION BEARING, GYROSCOPE, ON-TRACK TRAVELLING SYSTEM FOR ROTATING RIGID BODY FORMED BY DEVICE IN OVERRUNNING CLUTCH MANNER, AND METHOD AND TRANSPORTATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/168544
Kind Code:
A1
Abstract:
A combined bearing (1, 2, 3), a precession bearing (1, 2, 3), a precession bearing gyroscope, a gyroscope precession type active stabilization device, an on-sloped-track travelling system (8) for a precession bearing gyroscope overrunning clutch device (4, 88), and a method and a transportation system (8). The overlapping and separation of spherical raceways (181, 182, 183, 184, 288) of an inner ring (200) and an outer ring (100) of the combined bearing correspond to that of raceways in axial directions of the inner and outer rings, and motion control modes for different rolling bodies (141, 142, 301, 302, 403, 404, 51, 52, 888) are configured; the inner ring of the combined bearing forms an annular radial spherical raceway (288) and first and second raceways (466, 455) in the axial direction of the inner ring; the outer ring forms internal raceways of split-type first and second outer rings (11, 21, 31, 12, 22, 32); and the first and second outer rings of the combined bearing have different outer diameters, the outer rings on one side thereof are in interference fit with a bearing housing, the outer rings on the other side thereof are automatically tensioned in the axial direction by means of elastic elements (811, 902, 950) equipped with bolts (901), and a pair of the rolling bodies in the axial direction are also radially and flexibly pre-tightened by means of the elastic elements on cages (151, 152, 303, 304, 401, 402, 501, 502, 808), so that a bearing clearance can be automatically and flexibly adjusted. By using the combined bearing, related components, devices and systems can maintain stable and accurate movements.
