Simulation on Temperature Field of Gap Oil Film in Constant Flow Hydrostatic Center Frame
In order to solve the thermal deformation of the hydrostatic center flame in the heavy type horizontal lathe,a simulation research concerning temperature field of hydrostatic center frame is described.The Finite Volume Method of CFX has been used to compute three-dimensional temperature field of gap fluid between workpiece and bearing pillow.This research theoretically analyzes the influence of angular velocity on the bearing temperature performance according to lubricating theory and computational fluid dynamics,and it has revealed its temperature distribution law of gap oil film.Results indicate that an improved characteristic will be affected by angular velocity easily,and oil cavity temperature increases by gradually with angular velocity enhancing.Through this method,the safety of a hydrostatic center frame can be forecasted,and the optimal design of such products can be achieved,so it can provide reasonable data for design,lubrication,experience and thermal deformation computation for hydrostatic center frame in the heavy type horizontal lathe.
