Leadscrewdriven
Leadscrew-driven systems use a lead screw to convert rotary motion into linear motion. A lead screw is a threaded shaft and a corresponding nut that travels along the threads as the screw turns. The linear travel per revolution, known as the pitch, is determined by the screw design; single-start screws have a single thread and larger multi-start designs can increase advance per turn.
Key characteristics include simple construction, low cost, and the ability to hold position without power due
Compared with ball screws, lead screws generally offer lower efficiency, lower load capacity, and higher friction,
Applications span manual and motorized linear actuators, positioning stages, 3D printers, CNC machine slides, and general
