Abstract

The invention discloses an axial magnetic and gaseous combination bearing device and belongs to the technical field of high-speed rotary machinery. The axial magnetic and gaseous combination bearing device comprises a rotor spindle, a casing, a magnetic bearing thrust disc, an axial electromagnetic bearing, a first thrust disc and a dynamic pressure gas thrust bearing; the casing is used for mounting the rotor spindle; the magnetic bearing thrust disc is used for supporting the middle of the rotor spindle; the axial electromagnetic bearing is used for controlling the magnetic bearing thrust disc to be kept in the suspension state; the first thrust disc is used for supporting the end part of the rotor spindle; the dynamic pressure gas thrust bearing is used for controlling the first thrustdisc to be kept in the suspension state; permanent magnets are fixedly connected with the dynamic pressure gas thrust bearing and the first thrust disc and are spiral; and the dynamic pressure gas thrust bearing and the first thrust disc repel mutually. The axial magnetic and gaseous combination bearing device can provide auxiliary support, also has a bearing protection function and can effectively improve the working performance of a magnetic bearing.

Description

technical field [0001] The invention relates to the technical field of high-speed rotating machinery, in particular to an axial magnetic-air combined bearing device. Background technique [0002] Magnetic bearing is a supporting part that uses magnetic field force to support the rotor. It has the advantages of high speed, no friction, low power consumption, and low noise. It is especially suitable for high-precision and high-speed rotating machinery; Heat generation, in other words, it is easy to generate heat when the power consumption is large and the running time is long. When the magnetic suspension bearing fails, the rotor falling will cause serious damage to the magnetic suspension bearing and the rotor; therefore, it is necessary to reduce power consumption and provide auxiliary support, It also has an axial magnetic-air combination bearing device for protecting the bearing. Contents of the invention [0003] The purpose of the present invention is to solve the def...
