This calculator is designed to calculate torque required to raise the load and torque required to lower the load for Acme Lead Screw according to ASME/ANSI B1.5-1988 standard. This calculation may control the design of wide flange and similarly shaped columns when the torsional unbraced length is larger than the lateral unbraced length.
Haydon Kerk uses a unique precision rolling process for screw manufacturing. In most cases, even a properly connected free standing, built -up column will have about 60% of the strength of a solid column of the same material.
In the PV equation, pressure is simply the axial load divided by the contact area between the nut and the screw. However, finding the contact area for a helical mechanism, such as a lead screw, is more complicated than for a cylindrical design, such as linear bushing and shaft assembly.
