TL;DR: In this article, a reasonably simplified model of the pad is put forward, and the mathematical model of bearing characteristics of the multiple oil pad hydrostatic bearing is built with consideration of variable viscosity.

TL;DR: In this paper, the influence of the oil cavity depth on the temperature field in the heavy hydrostatic bearing is discussed in the context of variable viscosity, and the results of numerical calculations provide the temperature distribution state inside the heavy bearing, which would help the selection and the design of hydrostatic bearings in engineering practice.

TL;DR: In this paper, the effect of recess depth on the lubrication performance of a hydrostatic thrust bearing by constant rate flow was investigated. And the results demonstrated that the film temperature decreases and the oil film pressure first increases, and then decreases with the depth of recess.

TL;DR: In this article, a wedge-shaped structure opened on an edge of oil seal is put forward, the loss and insufficiency for hydrostatic bearing capacity are made up by using dynamic pressure, and then, hydrostatic hydrodynamic lubrication is realized.

TL;DR: In this paper, the deformation of the four-oil-pad radial hydrostatic bearing was calculated by using the finite element method, and the formula of film stiffness, film thickness and carrying capacity was established; the influence of the main parameters, such as load, load area and deformation on the supportability was analyzed.
