Problems solved by technology
However, passive magnetic suspension bearings are prone to displacement shocks when the supported parts are displaced axially, which affects the reliability of the system. The current method is to add an active control coil in the axial or radial direction on the basis of passive magnetic suspension bearings. , this method can eliminate the displacement oscillation, but this will increase the controller to control the increase of the active coil current, and at the same time, the axial sensor should be set in the axial direction of the system

The invention relates to the passive axial magnetic suspension bearing with the damp action, which comprises the static part and the movable part. The static part includes the static outside bearing body, the static repulsion permanent magnet, the magnetic conductor and the damp coil; the movable part is composed of the movable outside bearing body, the movable repulsion permanent magnet, the inside bearing body, the suction permanent magnet. The movable part and the static part are justified. In the static part, the magnetic conductor is equipped in the static outside bearing, the static repulsion permanent magnet is equipped on the static outside bearing, the damp coil on the magnetic conductor; in the movable part, the inside bearing is equipped in the movable outside bearing, the movable repulsion permanent magnet on the movable outside bearing, and the suction permanent magnet on the inside bearing. The polarity of the static repulsion permanent magnet is opposite to that of the movable repulsion permanent magnet and form the repulsion state.
Description
Technical field [0001] The invention relates to a non-contact magnetic suspension bearing, in particular to a passive axial magnetic suspension bearing with damping effect, which can be used as a non-contact support for rotating parts in mechanical equipment such as motors and machine tools. Background technique [0002] Magnetic suspension bearings are divided into active and passive types. Active magnetic suspension bearings are magnetic suspension bearings that superimpose the magnetic field generated by the control coil on the basis of permanent magnetic bias. Passive magnetic suspension bearings are magnetic suspension bearings that only have permanent magnetic fields. However, passive magnetic suspension bearings are prone to displacement shocks when the supported parts are displaced axially, which affects the reliability of the system. The current method is to add an active control coil in the axial or radial direction on the basis of passive magnetic suspension bearin...
