Thermal Analysis of High Speed Built-In Spindle by Finite Element Method

Article Preview

Abstract:

In this paper,the characteristics of GD-II built-in motorized spindle is introduced;the thermal features of the frameless motor and the hybrid bearings have been studied;the 2D temperature field model has also been developed by finite element method.The results of the calculation show that a good efficiency of heat transferring has been achieved with the oil-air lubrication and oil-water heat exchanger.
