Document Type and Number:
WIPO Patent Application WO/2020/217576
Kind Code:
A1
Abstract:
This bearing structure includes a rotation axis, a thrust collar, and a first thrust bearing. The rotation axis has a central axis. The thrust collar is attached to the rotation axis. The first thrust bearing includes a first dynamic pressure generation mechanism. The first dynamic pressure generation mechanism is opposed to the thrust collar. When the length from the central axis to a peripheral edge of the thrust collar is defined as Rt and the length from the central axis to a peripheral edge of the first dynamic pressure generation mechanism is defined as Rf1, the relation Rt > Rf1 is satisfied.
