“…At present, domestic and foreign scholars studied the thermal characterization of ball screws mainly through the friction torque, heat generation, and thermal convection formula to calculate the heat of each heat source and convective heat transfer coefficient, and then imported into the ABQUS software to get the simulation thermal field. G. Palazzo [2] has investigated the heat transfer in the working process of CNC machine tools and proposed a modeling method to study the thermal equilibrium of machine tools. Li Y [3] developed a finite difference method-based thermal properties model for a ball screw feed drive system considering moving heat sources, which can better predict the temperature change of the ball screw sub-system.…”

Aerospace ball screws cannot be lubricated for maintenance and replacement, so they use grease that can run for a long time and keep the performance. Under high speed and high load conditions, the ball screw will be warmed up rapidly, and the temperature has a great effect on the capability of the grease. In this paper, we deduce the formula for calculating the screw temperature, establish a thermodynamic simulation of the ball screw model to get its temperature under different conditions, and set up a test bench to try out the screw temperature rise to investigate thermal properties in the grease lubrication conditions.
