Oil Film Temperature Field Simulation of Hydrostatic Center Rack of Heavy-Duty Horizontal Boring Lathe

In order to research the temperature distribution law of the interstitial oil film on the hydrostatic center rack, the interstitial oil film on the hydrostatic center rack is taken as the research subject. Firstly, a three-dimensional model of the interstitial oil film is built by UG software. Secondly, the constructed three-dimensional model is meshed by ICEM CFD software. Lastly, the constructed finite element model is simulated using the finite element analysis software ANSYS CFX. The results of the simulation show that the temperature near the oil seal edge is higher than oil chamber and oil-returning slot. If the shaft parts rotate clockwise, the temperature of the right high-temperature zone is higher than the left. The research results provide a theoretical basis for the research on the thermal distortion of the middle pillow.
