Title: Magnetic disc device and bearing constituting body
Inventor: ARAI KATSUTOSHI
IPC: F16C33/10
Filed: 1989-04-17
Abstract: PURPOSE:To remove leakage and protect from dust by supporting an inner ring fixed on a spindle with a radial bearing, constituting magnetic fluid seals on both ends of the radial bearing with the inner cylinder surface of the inner ring, permanent magnets and pole pieces, and filling them with magnetic fluid in advance. CONSTITUTION:A bearing constituting body 18 is composed of an inner ring 20, a radial bearing 19 and magnetic fluid seals 4. The magnetic fluid seals 4 are composed of a permanent magnet 21, pole pieces 22, 23 and an inner ring 20. When an appropriate amount of magnetic fluid 24 is filled through a hole 26, it enters between the pole piece 23 and the inner ring 20 to form a magnetic fluid seal. The inner ring 20 becomes smaller in its diameter at a position slightly away from the gap 28 of its sliding surface, so that it does not come off from the bearing constituting body 17 because of the presence of a pole piece 23. Since the magnetic fluid seals 4 are located on both sides of the inner ring 20, the fluid does not leak and polluite the outside. Handling is easy since it can be installed on a spindle with the magnetic fluid self-contained. The bearing constituting body 17 is particularly suited for incorporation into a magnetic disc device 2.
