Title: Fluid bearing device
Inventor: ASADA TAKAFUMI
IPC: F16C33/10
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent the outflow of a lubricant by making the outer diameter of an upper shaft part and the diameter of an inner diameter part of a thrust plate smaller than the inner diameter of a sleeve bearing hole, providing a smaller diameter part than the bearing hole, on the base member side of a radial dynamic pressure groove, adjacently to the bearing hole, and providing an opposed fixed shaft with a small diameter shaft part. SOLUTION: A sleeve 10 and a thrust plate 7 are rotated by a motor rotor 13, and the sleeve 10 is rotated in a completely contactless state to a fixed shaft 2 by dynamic pressure grooves 3A, 3B, 5, 6. Since the outer diameter of an upper shaft 2A and the inner diameter of the thrust plate 7 are smaller than the inner diameter of a bearing surface 10F where the fixed shaft 2 abuts the sleeve 10, a lubricant 11 is moved form a small diameter part to a large diameter part by centrifugal force acting upon the lubricant 11 even during high speed rotation to prevent the lubricant 11 from flowing outside. Since the inner diameter of a small diameter part 2i of the fixed shaft 2 and the inner diameter of a small diameter part 10G of the sleeve 10 are smaller than the inner diameter of the bearing hole 10F, centrifugal force F1 acts upon a lubricant 11A even during high speed rotation, and its component force F2 prevents the lubricant 11A from flowing out from below.
