Clamping unit wanted
Hello :) (sorry for the bad english, but i really am in need of help)
I currently attend a mechanical school in Austria and have to design a new clamping unit for a lid.
The circular lid is loaded with a force of 60kN (the force acts on the center) and clamped with 4 units.
The currently existing units are equipped with star-shaped grips which have to be turned clockwise to clamp the lid.
The problem here is the particle generation of the thread.
Therefore, i am looking for another solution, which can applie the force needed to clamp the lid, but without the particle generation.
It has to be a manually operated solution.
I am thankful for every kind of advice you can give me and am thankful for you spending your time helping me.

These notes should get you started on the right track to determining the requirements for whatever you use to replace the screws in your flange.
