摘要： PROBLEM TO BE SOLVED: To reduce noise from a hard disk drive.SOLUTION: A rotary apparatus 100 includes: a rotor on which a magnetic recording disk 200 is to be placed; a stator which rotatably supports the rotor; and a driving mechanism rotating the rotor to the stator. A relation between a size of a clearance between the rotor and the stator and viscosity of lubricant 92 introduced into the clearance is decided when a peak of mechanical resonance at a translation mode of the rotary apparatus 100 and a peak of torque ripple of the driving mechanism are in a range of 1(kHz) to 5(kHz) in a frequency spectrum, so that a Q value of the peak of resonance becomes three or below.

摘要： PROBLEM TO BE SOLVED: To reduce deformation of a hub in the case of pressing a yoke into the hub. SOLUTION: In a brushless motor 100, the hub 10 has a cylindrical partition put between the yoke 30 and two magnetic recording disks 200. The yoke 30 is fixed on an inner peripheral surface of the partition of the hub 100 by adhesion and pressing. On the inner peripheral surface of the partition, a first recessed part 16 and a second recessed part 18 where the yoke 30 is abutted when the yoke 30 is pressed in are formed. The first recessed part 16 and the second recessed part 18 are circular recessed parts formed around a motor rotary shaft R. The diameter of first recessed part 16 is smaller than that of the second recessed part 18. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：为了在将轭压入轮毂的情况下减小轮毂的变形。解决方案：在无刷电动机100中，轮毂10具有放置在轭30和两个磁记录盘200之间的圆柱形分隔件。轭30通过粘附固定在轮毂100的分隔壁的内周表面上，紧迫。在隔板的内周面形成有磁轭30被按压时轭30抵接的第一凹部16和第二凹部18。第一凹部16和第二凹部18是形成在马达旋转轴R周围的圆形凹部。第一凹部16的直径小于第二凹部18的直径。（C）2010 ，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To load more magnetic recording disks.SOLUTION: A rotary apparatus 100 includes: a hub 10; a shaft 20 whose one end side is fixed to the hub 10; a first annularly surrounding member 80 for annularly surrounding the shaft 20; a second annularly surrounding member 82 fixed to the first annularly surrounding member 80, for annularly surrounding the shaft 20; and a base 50 to which the first annularly surrounding member 80 is fixed. A lubricant 92 is filled in a radial gap 112 between the shaft 20 and the first annularly surrounding member 80, and a radial dynamic pressure generation groove is formed on an inner peripheral surface 80h of the first annularly surrounding member 80. Both ends in the direction of a rotary axis R of the radial gap 112 are communicated through a communication hole 80d. A gas-liquid interface 92a of the lubricant 92 is positioned between the second annularly surrounding member 82 and the shaft 20. Between an inner side upper surface 80b of the first annularly surrounding member 80 and a lower surface 82a of the second annularly surrounding member 82, a pool space 102 for storing the lubricant 92 is provided. The communication hole 80d has one end in the pool space 102.
