This is my first time posting here.
Regarding compression springs, could you make a spring with a total number of 10 coils and 0.5 end coil for each end? Also, what is the difference between this spring and another one which has a total number of 11 coils and 1 end coil for each end? I look forward to hearing from you.
Spring Newbie, thank you for posting!
It is possible to manufacture a compression coil spring with a total number of 10 coils springs and 0.5 end coil for each end! In addition, the number of active coils according to the total number of coils and the number of end coils described is as follows.
With the total number of 10 coils and 0.5 end coil for each end, there are 9 active coils. If the total number of coils is 11 and the number of end coils is 1 for each end, the active number of coils is 9.
*Active coils (the part that operates to obtain repulsive force during compression)
In the case of 1 end coil, the non-active part is 1 coil and in the case of 0.5 end coil, the non-active part is 0.5 coil. Regarding the end shape, please check here .
Thank you!!!
Thank you for your reply.
I have another question, is it correct to think it is impossible to manufacture closed-ends for a compression spring with less than 1 end coil?
Spring Newbie, thank you for your question!
If both ends of the compression coil springs are in closed-contact with each other (= there is no gap at the end), it is obvious that the end coil is 1. Therefore, 0.5 end coil means that there is a gap at the end and it will be an open end.
