High speed spindle, spindle housing, double helical cooling channel and Turbulence analysis
The purpose of this paper is to numerically analyze the fluid motion and temperature distribution in built-in motorized high-speed spindle housing with double helical water cooling channel. A three dimensional finite element model of high speed spindle housing is developed and simulated using computational fluid dynamics software to determine the temperature distribution. The model is based upon a machine tool spindle of 5KW and maximum speed of 40,000 rpm. The effect of heat flux (q"= 3I0867 W/m2) with different cooling water velocity are examined in detail. The results are compared with a single helical cooling channel and it indicates that the designed cooling loop is more effective and increase in temperature can be reduced significantly.
