When your first idea is drafted you calculate which forces/pressures and so on are working on your system. And then you break the forces down into the single screws which are built in your device.
Exemplary let’s say, that screw is loaded axially with $8000 \ N$ – the transverse load could be unattended.
How do you decide to take the right screw dimension? Things that should in my opinion be also considered are:
- How is the load working on the screw?
- concentrically vs. eccentrically
- static vs. dynamic
- How is the montage of the screw realized?
- Simple tightening spindle vs. tightening by angle monitoring in the plastic range
- What degree of utilization is allowed?
- What is the strength grade of the screw?
- And perhaps many more points…
The aim that I’m expecting is, something like: With these forces, this montage, this strength grade and … (simple calculation) … you have to take a screw M16x2 10.9
I’m curious to hear your experiences.
Thanks in advance for your help.
