Abstract

The invention discloses a magnetic-air suspension axial bearing with a porous medium, which comprises a static air pressure system and an electromagnetic suspension system. The bearing comprises a shaft, a thrust disc, a first stator, a second stator and an adjustment pad, wherein eight magnetic poles are arranged on the first stator and arrayed according to an NSSNNSSN manner; every two adjacentmagnetic poles are a pair; and the second stator and the first stator have the same structure. An assembly relationship is as follows: the external circumference of the thrust disc is sleeved with theadjustment pad; the first stator and the second stator are oppositely mounted on the two sides of the thrust disc; and the magnetic poles of the first stator and the second stator face towards the inner side. The bearing can integrate the static air pressure system and the electromagnetic suspension system; an auxiliary support and circulatory cooling system is not required to be adopted independently; the friction and abrasion of the bearing can be greatly reduced; and the carrying capacity and rigidity are improved.

Description

[0001] Field of study [0002] The invention relates to the design field of sliding bearings, in particular to a magnetic double-suspended axial bearing with porous media. Background technique [0003] The air static pressure bearing uses air as the lubricating medium. When the external compressed gas enters the bearing gap through the restrictor, a layer of lubricating gas film with a certain load-bearing and rigidity will be formed in the gap. float in the bearing. Aerostatic bearings have the advantages of low friction, low power, high speed, and high cleanliness, so they are widely valued and widely used. However, the support stiffness and bearing capacity of aerostatic bearings are low, and they are not suitable for high-power and heavy-load operation. SUMMARY OF THE INVENTION [0004] According to the above-mentioned problems in the prior art, a magnetic double-suspended axial bearing with porous media is provided. The invention uses the electromagnetic suspension b...
