They hold together everything from the most delicate watch to the largest bridge. The world is literally kept from coming apart by screws and bolts, and yet we don’t often give a thought to these ...

Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism ...

Planetary roller screw mechanisms (PRSMs) are advanced mechanical devices that convert rotational motion into precise linear displacement. Their design capitalises on an array of rolling elements ...

For automatic correction of accumulated errors in the lead screw in the pitch and in the inside pitch of lead screw we use the same lead screw: 1. On the top of the helixes of screw we make a ...
