Abstract
A fluid dynamic bearing includes a bearing sleeve and a shaft rotatably received in the bearing sleeve with a bearing clearance formed therebetween. Lubricating fluid is received in the bearing clearance. A number of dynamic pressure generating grooves are formed on an inner peripheral surface of the bearing sleeve. The inner peripheral surface of the bearing sleeve and the shaft form therebetween first and second radial distances along a rotating direction of the shaft. The first radial distance is greater than the second radial distance. Upon rotating of the shaft, the lubricating fluid at the first radial distance is driven toward the second radial distance to establish a pressure separating the bearing sleeve and the shaft apart.
