Title:

PIVOTING MICRO-FRICTION OR FRICTION-FREE RADIAL PERMANENT MAGNET FLOATING BEARING

Document Type and Number:

WIPO Patent Application WO/2015/101276

Kind Code:

A1

Abstract:

A radial permanent magnet floating bearing, comprising: a horizontal shaft (2), a support bearing (4), and a radial permanent magnet floating bearing (3); the permanent magnet floating bearing (3) comprises a stator pull-push magnet (31) disposed on a stator casing (1) via a magnetic substrate (322), and a rotor pull-push magnet (32) disposed on the horizontal shaft (2) correspondingly via an annular magnetic substrate (322), having a radial gap and forming an axial pull-push magnetic circuit with the stator pull-push magnet (31); the rotor pull-push magnet (32) consists of two or more annular permanent magnets axially and closely attached, with magnetic poles alternately arranged in the axial direction; the stator pull-push magnet (31) consists of two or more annular permanent magnets axially and closely attached, with magnetic poles alternately arranged in the axial direction, disposed over the horizontal panel where the axle center of the horizontal shaft (2) is located, and being symmetrical about the perpendicular bisection plane of the horizontal axis. The bearing has a simple structure and greatly reduces energy consumption, without wear or bearing maintenance.
