Title: Dynamic pressure bearing, rotary body device and motor
Inventor: GOTO HIROMITSU
IPC: G11B19/20
Filed: 2002-08-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing having a seal part for effectively restraining leakage of oil.  <P>SOLUTION: The seal part 15 is constituted by using a tapered shaft side taper part 16 formed on a shaft 6 and a sleeve side taper part 17 formed in an inserting hole 21 of a sleeve 12. When the shaft 6 inclines from the rotational axis at stopping or rotation, clearance between an outer peripheral surface of the shaft 6 and an inner peripheral surface of the inserting hole 21 reduces in an opening part of the inserting hole 21. However, even if the clearance reduces by the shaft side taper part 16 and the sleeve side taper part 17, the clearance for holding the oil 13 in a dynamic pressure bearing part 23 is secured so that the oil 13 can be effectively restrained from leaking from the opening part of the inserting hole 21.  <P>COPYRIGHT: (C)2004,JPO
