Thrust bearing is one of the most important components in ESPCP system, which determines the life of the whole system under the restriction of some factors such as the installation depth and the viscosity of swabbed petroleum oil etc. To increase the ability of high temperature resistance of thrust bearings under the limited radial size, the damage reason of applied bearings was analyzed. Some different modified methods were employed on configuration and material. Contact problems were researched with finite element analysis software. Comparison of the analysis results shows that in the tube, it is optimum that 8 rollers thrust bearings are used in 10mm radial tube without holders.

Thrust bearing is one of the most important components in esPCP system, which determines the lifespan of the whole system under the restriction of some factors such as the depth of downhole unit, the viscosity of petroleum oil to be pumped. To increase the high temperature bearing ability of the bearings under the limitation of radial size, the damage reason of pre-applied bearings was analyzed. Some different modified plans were put forward from two aspects of structure and material. Contact problems were researched for different plans with finite element analysis software of ANSIS. Comparison of results shows that, in the well of 5½" tube, the optimum selection is ball thrust bearing with 8 balls of radial size of 10mm without keeper.

Thrust Bearings

This paper proposes a method to calculate the characteristics of a coupled fluid dynamic journal and thrust bearing of a hard disk drive (HDD) spindle motor. The governing equations for the journal and thrust bearings are the two-dimensional Reynolds equations in the θz and rθ planes, respectively. The finite element method is appropriately applied to analyze the coupled bearing under the conditions of the continuity of mass and pressure at the interface between the journal and thrust bearings. The pressure in the coupled bearing was calculated by applying the Reynolds boundary condition. The validity of this application was verified by comparing the analytical results of the flying height at various rotating speeds with experimental results. The characteristics of the coupled journal and thrust bearing were also investigated due to the Reynolds and Half-Sommerfeld boundary conditions and the coupled and separate analysis. This research demonstrates that the proposed method can accurately and realistically describe the coupled fluid dynamic bearing in a HDD system.
