A twisting motion on the ballnut. Applying force that pushes each end of the ballnut in the opposite direction from the center of the screw, in a radial direction.
A load that pulls the screw, such that the load is pulling from each end, away from the center of the screw
A load that compresses the screw, such that the load is pushing from each end of the screw towards the center
The thrust load is applied parallel to the assembly
The static load is the maximum thrust load that can be applied to a ballscrew assembly without causing damage. Usually, it is considered a single load that will cause catastrophic failure. At PST, we calculate the static load using the…
