Title:
MAGNETIC SUSPENSION BEARING
Document Type and Number:
WIPO Patent Application WO/2006/122448
Kind Code:
A1
Abstract:
The present invention discloses a magnetic suspension bearing, it comprising: an outer layer which encloses a plurality of magnets and is made of magnetic material, an inner layer which encloses a plurality of magnets and is made of magnetic material, an outer enclosure which is located at one side of the outer layer and encloses the outer layer to form a magnetic barrel, and an inner enclosure which is located at one side of the inner layer and encloses the inner layer to form a magnetic barrel. As mentioned above, when assembling the bearing, the outer layer and the inner layer are assembled together, and the magnets in the inner layer and the outer layer are disposed staggeringly up and down, remaining a gap between each pair of the magnets so as to generate a magnetic suspension force produced from repulsion force between magnets of the same polarity. With this magnetic suspension bearing, the shaft is able to rotate with high speed yet less generation of heat by friction, due to a gap between an upper end and a lower end of the inner and outer layer the magnets therein will not impact each other even if vibration therebetween is more than a limit, and the outer enclosure and the inner enclosure as magnetic barrels encloses the outer layer and the inner layer so that some components are protected from magnetic force generated by the magnets, which improve the durability of the bearing compared with a conventional pivot or ball bearing.
