Title: Magnetic bearing
Inventor: ABUKAWA TOSHIMI
IPC: F16C32/04
Filed: 1979-03-28
Abstract: PURPOSE: To obtain a magnetic bearing whose radial spring constant is almost not changed axially for a displacement, by forming one magnet at either rotary side or fixed side into a height in the direction of axis larger than that of the other magnet at the other side.  
     CONSTITUTION: The magnetic bearing comprises a magnet 2 at rotary side installed to a shaft 4 by a ring 3 and a magnet 5 at fixed side which is in the same height, axially magnetized in the same polarity as the magnet 2 at rotary side and arranged concentrically with radially outside the magnet 2 at rotary side. Here the height h 2  axially of the magnet 5 at fixed side is formed longer than the height h 1  axially of the magnet 2 at rotary side. In this way, if the height axially of the magnet 5 at fixed side is formed larger than that of the magnet 3 at rotary side, the amount of displacement can be less affected for the radial force even for displacement axially of the magnet 2 at rotary side, resulting in the provision of a characteristic of radial spring constant almost not changing its value even for a considerable amount of displacement axially caused.
