Research On Dynamic Pressure Effect Of Heavy Hydrostatic Thrust Bearing With Parallel Quadrilateral Oil Chamber Structure Based On Fluent

Heavy hydrostatic thrust bearings are the main load-bearing components of large equipment,with low frictional resistance,long service life,and strong vibration resistance.They have been widely used in fields such as energy,transportation,nuclear power,wind power,and heavy-duty machine tools.With the continuous improvement of production level in China’s manufacturing industry,the performance requirements for heavy-duty hydrostatic thrust bearings are also increasing.Under heavy load conditions,heavy hydrostatic thrust bearings increase the heat generation of the oil film and decrease the viscosity of the lubricating oil due to continuous shearing and squeezing of the oil film by the workbench.In severe cases,it can cause tribological failure and have adverse effects on the bearing capacity and stability of heavy hydrostatic thrust bearings.Therefore,it is necessary to improve the load-bearing capacity and performance of heavy-duty hydrostatic thrust bearings.This article conducts a detailed study on the dynamic pressure effect of heavy-duty static pressure machine tools based on a double rectangular oil cavity structure,and mainly analyzes it through simulated temperature and pressure field cloud maps.A parallelogram oil cavity structure was proposed based on the double rectangular oil cavity.Solid Works software was used to create a model of the parallelogram oil cavity,ICEM CFD software was used for grid division,and FLUENT software was used to simulate the temperature and pressure fields of the parallelogram cavity.The simulation cloud map was compared with the double rectangular oil cavity.The structural optimization of the new cavity is mainly analyzed from two aspects: the position of the oil inlet and the angle of the cavity.And analyze the dynamic pressure effect of the new cavity under different working conditions through software simulation,and optimize the cavity effect.
