Why we need Pitch Transition coil in the compression springs?. And how to choose the number of pitch transition coil ?
Thank you for your inquiry.
I will answer assuming that the Pitch transition coil is the end turn of the coil spring.
Basically, the seat winding of a coil spring is considered to be one winding at each end.
We can design it to be 0.75 or 1 or more depending on the stability of the spring and the space available.
If you have any questions, please contact us.
