Abstract

The invention discloses a magnetic gas double-suspension breaking-type cone bearing with porous media. The cone bearing with an air static pressure supporting system and an electromagnetic suspensionsupporting system comprises first and second bearing end covers, a rotor shaft, first and second stators, first and second magnetic conductive sleeves, first and second enameled coils, an adjustment ring, first and second dust-proof seal rings, and the first and second porous media; according to the air static pressure supporting system, air enters from air inlet holes of the two stators, passes through air inlet cavities to act on the two magnetic conductive sleeves through the porous media, and forms tapered aeroelastic potential energy between the two stators and the two magnetic conductivesleeves, and accordingly, axial and radial support of the bearing is realized; the electromagnetic suspension supporting system is realized by the physical principle of electromagnetic attraction onthe two stators. The magnetic gas double-suspension breaking-type cone bearing has the advantages that the abrasion of the bearing can be remarkably reduced, the rotation speed can be increased, separate arrangement of auxiliary supports and circulating cooling systems is not needed, and the adjustment capability and the precision of a bearing system are improved.

Description

technical field [0001] The invention relates to the design field of sliding bearings, in particular to a magnetic double-suspension support segmented taper bearing with small friction, high rotational speed and high control precision. Background technique [0002] Aerostatic bearings use air to provide static pressure to support the rotating shaft. They have the advantages of low friction, low power, high speed, and high cleanliness, so they have been widely valued and widely used. However, aerostatic bearings are not suitable for high-power and heavy-duty applications. The electromagnetic suspension bearing is a bearing that uses magnetic attraction and repulsion to support the rotation, also called magnetic suspension bearing. Its advantages are small torque, good for high-speed rotation, can be used in vacuum, wide applicable temperature range, low noise, long life, no pollution caused by lubrication, etc.; disadvantages are high cost and relatively low carrying capacity...
