Hi everyone,
Im gonna use ACME screw to build my second machine, i faced some doubts when choosing the leadscrews... Its not the pitch or diameter... I want to know how does the starts affect on the efficiency of everything...
Lets say I choose a ACME screw with 14mm diameter and 4mm pitch, with one start only... Lets supose that this will give me a efficency of 50% ( i dont know im just making the number for an example)
What about if I use the same 14mm diameter and 4mm pitch but with 2 starts... So the spacing of each thread it would be smaller... But it will still move 4mm with a turn.... Will it be more efficient or less efficient? I suspect it would be better with 2 starts, or maybe even more! If its possible to make...
Lets consider both situations using the same length, size, kind and material of nut
So... Any mechanicals enginners that knows the answer for this? Or other person who got the knowledge of that...
Thank you in advance to everyone
