by Jignesh Sabhadiya A lead screw is usually a type of mechanical energy transmission used in equipment for top-precision actuation. It converts rotational movement into linear motion. Other names for any lead screw (or leadscrew) are power screw and translation screw.
Since the failure of lead screws may possibly lead to really serious mishaps, an increased component of basic safety of 3 to 5 is taken. Threads could fail as a result of shear, which may be avoided by using a nut of ample top. Don is an additional achievable mode of thread failure is as nuts and bolts rub against one another.
