power screw
Quick Summary
A power screw is a type of screw used to modify motion and force, functioning as a simple machine. It converts torque, or turning force, into thrust. This is achieved by turning a screw within a stationary nut. By using a long bar to turn the screw, a small applied force can generate a large thrust force, making it useful for lifting heavy objects, as in a screw jack. Power screws are also employed in machine tools to move workpiece tables linearly along guiding ways. This mechanism allows for precise linear motion through rotational input.12
