Integrated magnetic levitation bearing

Abstract

An integrated magnetic levitation bearing relates to the technical field of bearings. The integrated magnetic levitation bearing includes an axial bearing component and a radial bearing component. Theaxial bearing component is provided with a receiving groove in the axial direction. The radial bearing component is disposed in the receiving groove and is fixed to the axial bearing component. The inner diameter of the axial bearing component is aligned with the inner diameter of the radial bearing component. The radial bearing component is fixed in the receiving groove disposed in the axial direction of the axial bearing component, thereby integrating the radial bearing and the axial bearing into one body, effectively reducing the axial size of the magnetic levitation bearing, and optimizing the overall structure, reducing the overall axial size, and making the integrated magnetic levitation bearing convenient to be used in to small spaces. Further, the radial and axial bearings are notrequired to be assembled separately when a whole machine is assembled, which reduces the assembly difficulty and improves the assembly efficiency. An good axiality effect is achieved after the wholemachine is assembled, which helps the magnetic levitation bearing to control and adjust rotor levitation accuracy.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an integrated magnetic suspension bearing. Background technique [0002] Magnetic suspension bearings use electromagnetic force to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator, and there is no mechanical friction. It is a low-loss, high-performance bearing. While achieving high rotor speed, it also has the advantages of no mechanical wear, low energy consumption, low noise, long life, no need for lubrication and sealing, and no oil pollution. The rotor speed of the magnetic suspension bearing is only limited by the tensile strength of the rotor material, so The peripheral speed of the magnetic suspension bearing can be very high, and it is more and more widely used in high-speed equipment. [0003] Magnetic suspension bearings can be divided into three categories according to the working principle of magnetic suspension b...

Problems solved by technology

[0007] Among the above three magnetic suspension bearing structures, the active magnetic suspension bearing is the most widely used at present. Usually, the active magnetic suspension bearings are arranged separately from the radial and axial bearings, resulting in an increase in the axial dimension, which affects the overall size of the product in the axial direction.
