ABSTRACT　　The　invention　relates　to　a　magnetically　levitated　nutation　spherical　bearing　and　a　　working　method　thereof.　The　magnetically　levitated　nutation　spherical　bearing　　comprises　a　bearing　cover　and　nutation　balls　positioned　in　the　bearing　cover,　　wherein　　the　bearing　cover　comprises　an　upper　bearing　cover　and　a　lower　bearing　cover;　　a　　plurality　of　grooves　are　arranged　in　the　upper　bearing　cover　and　the　lower　bearing　　cover,　　and　permanent　magnets　II　are　arranged　in　the　grooves;　　the　nutation　ball　includes　　a　nutation　sphere,　　which　is　fixedly　connected　with　a　plurality　of　nutation　input　shafts,　　　a　plurality　of　grooves　are　arranged　on　the　nutation　sphere,　　and　a　first　permanent　magnet　　is　arranged　in　the　groove　of　the　nutation　sphere;　　the　number　of　grooves　on　the　upper　　bearing　cover　and　the　lower　bearing　cover　are　consistent　and　their　positions　are　　opposite,　　and　the　grooves　on　the　nutation　sphere　are　opposite　to　those　in　the　bearing　　cover.　The　first　permanent　magnet　and　the　second　permanent　magnet　are　radially　　magnetized,　　and　the　opposite　faces　of　first　permanent　magnet　and　second　permanent　　magnet　have　the　same　magnetism.　The　spherical　bearing　of　the　invention　adopts　　permanent　magnet　suspension,　　which　has　the　advantages　of　no　friction,　　no　lubrication,　　　low　noise,　　less　heat　generation,　　high　energy　efficiency　ratio　and　the　like,　　it　can　realize　　nutation　transmission,　　thoroughly　solves　the　problem　of　mechanical　wear,　　and　greatly　　improves　the　performance　and　service　life　of　the　spherical　bearing.　1/2　　FIGURES　　Figure　1　　4　　Fr　　Figure　2
