Coefficient of Friction of Power Screw given Effort Required to Lift Load

LaTeX Go Coefficient of friction at screw thread = (Effort in lifting load-Load on screw*tan(Helix angle of screw))/(Load on screw+Effort in lifting load*tan(Helix angle of screw))

Helix Angle of Power Screw given Effort Required to Lift Load

LaTeX Go Helix angle of screw = atan((Effort in lifting load-Load on screw*Coefficient of friction at screw thread)/(Effort in lifting load*Coefficient of friction at screw thread+Load on screw))

Load on Power Screw given Effort Required to Lift Load

LaTeX Go Load on screw = Effort in lifting load/((Coefficient of friction at screw thread+tan(Helix angle of screw))/(1-Coefficient of friction at screw thread*tan(Helix angle of screw)))

Effort Required in Lifting load using Power Screw

LaTeX Go Effort in lifting load = Load on screw*((Coefficient of friction at screw thread+tan(Helix angle of screw))/(1-Coefficient of friction at screw thread*tan(Helix angle of screw)))

Load on Screw given Overall Efficiency Formula

LaTeX Go

Axial load on screw = 2*pi*Torsional Moment on Screw*Efficiency of power screw/Lead of Power Screw
W_a = 2*pi*Mt_t*η/L

Axial Load and Overall Efficiency

Input work can be mathematically expressed as the product of Axial load and Lead of the Screw. Since the Overall Efficiency of any Screw-Nut Pair is constant, an increase in Axial load implies an increase in input and output work, Thus making a requirement for a bigger External Torque to rotate the screw.
