Top foil plate for dynamical pressure die fluid film thrust bearing

摘要

(57) Abstract The dynamical pressure die fluid film thrust bearing (10) the top foil (12), is formed from single even annular disk. From the major diameter extending it is present to inside diameter and at the same time the foil plate (16) to with faces and the radial cavity which projects (30) it possesses this annular disk, during the cavity which these adjoin in order taking the foil bumper which is stuck (14) to compensate in the foil plate, the operation aspect which is formed (39) is demarcated. Making axial direction match, it lays out the foil for cushioning upper part foil plate, or and the foil for cushioning bottom foil plate, shifts mutually and it is possible also to lay out. Shifting the foil for cushioning these 2 sets, when it lays out, the leading edge of the foil for upper part cushioning (31) it is located on high-level side the leading edge of the foil for bottom cushioning (33) (in regard to the direction of the air current inflow into the foil for cushioning).
