Embodiment Construction
[0032] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.
[0033] An elliptical tile air dynamic pressure radial foil bearing with positive and negative rotation directions, comprising a bearing sleeve 1; a corrugated foil 2; a top foil 3;
[0034]The bearing sleeve 1 is a hollow cylinder used to fix the corrugated foil 2 and the top foil 3, and one or two or three dovetail structures 4 with an angle of 120 degrees to each other can be opened on the bearing sleeve 1 (When there is only one dovetail groove, the top foil 3 and the corrugated foil 2 are circular, as shown in the attached Figure 6 (a), with Figure 7 As shown in (a), when the relative dovetail groove 4 is used, the top foil 3 and the corrugated foil 2 are double-lobe separated, as shown in the attached Figure 6 (b), with Figure 7 As shown in (b), the top foil 3 and the corrugated foil 2 used when...
