Webb21 maj 2015 · When a ball screw is used in a vertical application, it sees the full load as an axial force, which makes buckling a more important concern. Mounting the screw assembly with the most rigid support (typically the fixed bearing) at the top puts the screw in tension rather than compression and counters the effects of the axial load. Webb2.11 Tensile/Compressive stress in the direction of the screw axis . Tensile/Compressive stress in the screw core. 2.12 Equivalent stress. In case of simultaneous action of tensile stress / pressure and torsion, it is necessary to deal with combined stress and loads. The reduced stress should be less than the allowed tensile stress.
