Hello. Nice to meet you, my name is Super Beginner.
There are some things that I don’t understand when ordering a flat spiral spring. In an experiment, I wanted to use a flat spiral spring, but I didn’t know the torque, so I used a rubber band. As a result, I found that the required torque from the rubber band was 5.75 [N* mm]. So I have a question.
The flat spiral spring is used by winding it several times in the opposite direction of rotation, right? When I disassembled the headphones, it was like that … Considering that the flat spiral spring is wound in the opposite direction about 5 times at the beginning, I think that the required torque will be 5.75/5. Is the torque when ordering 1.15 [N * mm]/1 time?
This may be a rudimentary question, but I would appreciate your advice.
Super Beginner, thank you for writing!
[Question] The mainspring is used by first winding it several times in the opposite direction of rotation, isn’t it?
[Answer] That’s right!
[Question] Will the torque, when ordering, be 1.15 [N * mm]/1 time?
[Answer] It is 5.75 N*mm at 5 rotations. Thanks for your question!
