Study on the Thermal Characteristics of a Motorized Spindle Unit

Abstract:

Heat generation and heat transfer of motorized spindle unit are studied in this paper, including heat generation of built-in motor and rolling bearings, heat conduction, convection and radiation between spindle components. By modeling a FEM model of a high performance motorized grinding spindle, thermal characteristics simulation of the spindle unit is completed. The thermal characteristics under different spindle speeds, different cooling water flow rates and different forced air flow rates are simulated. The numerical results show that spindle speed and cooling water flow rate have significant influences on thermal characteristics of motorized spindle unit. These results are useful to guide the design and verification of motorized spindle unit.
