Embodiment Construction
[0022] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] The invention mainly aims at the basic requirements of not increasing the axial length of the bearing and not increasing the air gap between the electromagnetic bearing and the rotor journal, and designs the structure for installing the elastic foil bearing.
[0024] refer to figure 1 , an overall structure of an electromagnetic-elastic foil hybrid bearing arranged in series, including a bearing seat 17, an electromagnetic bearing 1 is arranged in the bearing seat 17, a magnetic pole 6 is arranged on the electromagnetic bearing 1, and a coil 7 is wound on the magnetic pole 6, and the electromagnetic bearing 1 A left end cover 2 and a right end cover 3 for pressing the magnetic pole 6 are arranged in the axial direction, and two elastic foil bearings 5 are nested between the left end cover 2 and the ri...
