The simplicity of screw threads and the ubiquity of threaded fasteners belie the physics behind these mechanisms, but understanding the basics is a great place to start.

Planetary roller screw mechanisms (PRSM) are advanced mechanical systems that convert rotational motion into linear motion, commonly used in applications requiring high load capacity and precision ...

particularly in planetary roller screw mechanisms (PRSM). This research highlighted the challenges associated with grinding such intricate profiles and established a numerical model to analyze the ...

Keen-eyed readers will recall [Andy]’s recent scratch-built ball screw build ... were a great lesson in how to machine a complex mechanism to work in a constrained space. Still, it left folks ...
