Abstract

The invention discloses a permanent magnetic suspension carrier roller. The permanent magnetic suspension carrier roller comprises an axial magnetic unit (2) and a radial magnetic unit (3). The axial magnetic unit (2) comprises an axial outer ring magnet (21) installed on an outer magnet base (4) and an axial inner ring magnet (22) installed on an inner magnet base (5), the polarities of the magnetic fields on the opposite faces of the axial outer ring magnet (21) and the axial inner ring magnet (22) are opposite, and the axial outer ring magnet (21) and the axial inner ring magnet (22) are in non-contact rotary fit. The radial magnetic unit (3) comprises a radial outer ring magnet (31) installed on the outer magnet base (4) and a radial inner ring magnet (32) installed on the inner magnet base (5), the polarities of the magnetic fields on the opposite faces of the radial outer ring magnet (31) and the radial inner ring magnet (32) are opposite, and the radial outer ring magnet (31) and the radial inner ring magnet (32) are in non-contact rotary fit. The magnetic field of the carrier roller is stable; mechanical friction can be eliminated; abrasion, energy consumption and noise are reduced; lubricated seal is not needed; the service life is long; the flexibility and the bearing capacity of the carrier roller are improved.

Description

technical field [0001] The invention relates to a bearing device, in particular to a permanent magnet magnetic levitation idler roller capable of generating stable radial levitation force and axial force at the same time, specifically a permanent magnet magnetic force line with longitudinal tensile resistance and transverse compression resistance The nature of the force makes the suspension support force between the permanent magnets and the axial force respectively perpendicular to the air gap magnetic lines of permanent magnetic maglev idler. Background technique [0002] At present, idler rollers are widely used in various industries. The role of idler rollers is to support the weight of conveyor belts and materials. The quality of the idler is mainly reflected in: the radial runout of the idler, the flexibility of the idler and the axial movement. But it is not easy to manufacture high-quality rollers. Contents of the invention [0003] The object of the present inve...
