friction is omitted purposely from the assumption, (read 1st post) there are no balls at this stage, Its just for proving the maths, thanks by the way. i find it interesting that force output through a screw can be calculated with the ratio of the pitch (distance traveled axially) to the...

bieng as the screw moved 2.5mm of linear movement for a total circular movement of 25.1327412mm , is that not proportional to the output ratio in itself? 25.1327412/2.5 = 10.05 would then an input force be multiplied by this 10.05 ratio to give what's output? i.e 10nm torque input on the short...

Hi all, my first post here, I've succumbed to some help if possible, i know its wrong but it's getting my goat! now, and many times in years gone by. I am building something as always, and reverse engineering exisiting drive components to select suitable new ones if that makes sense. In...
