A kind of distributed hybrid thrust bearing with tilting pad is proposed in this paper, and the influence plate tilt on performance analyzed. The film thickness equation constructed, considering machining error installation synthetically which are main causes tilt. Substituting to classical calculation bearing, time-varying stiffness obtained. angle analyzed through case controlled by change pi...

The orifice-compensated with feeding pocket annular hydrostatic (OCFPAH) thrust bearing is a unique type of gas bearing with many distinguishing characteristics. It is finding many applications in ultra high-speed rotors. A computer code was written to overcome the difficulties involved in the design of such a bearing. Initially, the design charts were converted into the alternative equations u...

In this article, the main causes of vibration in thrust bearing hydrogenerator motors rated 320 MW are considered. The types internal and surface defects that appear on working disc during long-term operation A method three-dimensional modeling such is presented, an assessment stress-strain state heel proposed, taking into account forces acting using finite element method. An analysis possible ...

The axial loads of high-speed rotating turbo machines are supported by self-acting hydrodynamic components known as air foil thrust bearings (AFTB). load bearing capability these depends primarily on the structure and secondarily operating conditions. present review enlightens tribological performance parameters said in enhancing carrying capacity. Various design fabrication methods including t...
