초록
In this study, the ways of calculating the efficiency of ball screws are presented to fix the design variables effectively. To calculate the efficiency of ball screws, the frection coefficient is needed to be deduced. Therefore it is deduced measuring the preload torque of double nut ball screws of which the preload can be varied by springs. The efficieny of ball screws and the mazimum efficiency condition are calculated with the deduced friction coefficient. In addition, the characteristic of friction and lubrication is considered.
