The relationship between pitch of the chain (p) and pitch circle diameter of the chain sprocket (D) is given by
1
\(p = D\sin \left[ {\frac{{{{90}^o}}}{T}} \right]\)
2
\(p = D\sin \left[ {\frac{{{{120}^o}}}{T}} \right]\)
3
\(p = D\sin \left[ {\frac{{{{180}^o}}}{T}} \right]\)
4
\(p = D\sin \left[ {\frac{{{{360}^o}}}{T}} \right]\)
