A screw drive is a type of mechanical device that converts rotational motion into linear motion. It typically consists of a screw and a nut, where the screw's helical thread engages with the nut to create movement along a specific axis. This mechanism is commonly used in various applications, such as automobiles, machinery, and construction equipment. Screw drives are known for their ability to provide high levels of torque and precision. They are often used in actuators and linear motion systems to control the position of components. The efficiency and reliability of screw drives make them essential in both industrial and everyday applications.
