Study on the Performance of Liquid Metal Lubricated V-Groove Bearing Considering Turbulence

To study the application of liquid metal (LM) in field practical lubrication, viscosity gallium based (GBLM) was measured initially, and relationship between temperature fitted to obtain under high temperature. Under simulated vacuum working environment computed tomography tube (CTT) machines, considering influence turbulence, changes, with eccentricity, bearing capacity, discharge, friction power consumption, rise, stiffness, critical mass GBLM lubricated V-groove (V-g B) were analyzed. Due special structure V-g B, coordinate transformation carried out turbulent Reynolds equation solved by using finite difference method local integral method. The film thickness pressure distribution two systems analyzed compared B small eccentricity large studied, respectively. performance which provides theoretical guidance an analytical for LM high-performance CT equipment.
