I need to add 0.1nm torque to my system
Hello,
I am designing this device. I am stuck with a problem that I can't find an off the shelf solution for.
Basiclly this device needs to rotate in two directions (refer to picture 2) **very smoothly** **and with very prceise small angle rotations (like 1 degree)** and when left alone it should hold its position. to achive that I added torque hinge.
I started with 1NM torque hinge. the hinge was thick and sturdy. The problem I got is because the torque is too high, the rotation was not precise. if I apply small force to rotate, the system would rotate back to its old position. I would need more force to make the torque hinge slip. but if I apply more force the system would rotate like 5 degrees.
I tried a 0.1 NM hinge. the hinge was thin and weak. I managed to get the small angles rotation that I needed but the weight of the system caused the hinge to bend.
There is no thick and sturdy 0.1 NM hinges on the market.
What I plan to do now is have a 0 NM thick and study hinges installed. Then put around the hinges something that could introduce small torque.
Are there any suggestions? I can edit my design to integrate new parts.
