| Abstract: | During the design of a hydraulic bearing system, temperature raise of oil is one of the main problems that always puzzle people, and how to determine the value of viscosity is also very important. This paper carries out researches into the simplified model of hydrostatic thrust bearing and hydrostatic slipring, and the distribution of viscosity in hydrostatic thrust bearing and building the formula of temperature raise of the hydraulic bearing's in and out oil. The results have significant theoretical and practical values to the study of fluid characteristics with variable viscosity. |
