Abstract: The temperature rise and thermal deformation of the magnetic-hydraulic double suspension bearing can easily lead to thermal balance instability and reduce the running stability of the bearing. In this paper, the influence of structural parameters on the temperature rise and thermal deformation of the magnetic pole is studied, and the stator of the bearing is optimised. The research shows that with the increase of the number of magnetic poles, the temperature rise and thermal deformation are basically unchanged; with the increase of the number of coil turns, the temperature rise and thermal deformation show a linear growth trend; with the increase of the wire diameter, the temperature rise and thermal deformation decrease rapidly. The order that affects the temperature rise and the degree of thermal deformation is the number of turns of the coil > the diameter of the wire > the number of magnetic poles.

Keywords: magnetic-liquid double suspension bearing; electromagnetic suspension; hydrostatic bearing; liquid-solid-thermal coupling; structure parameters; orthogonal experiment.
