Pulley Drawings Symbols
N = Number of pitch lengths or teeth on a pulley
P = Pitch is the distance between the axes of two adjacent teeth irrespective of whether these teeth are on the pulley or
the belt provided that measurement is taken on the circumferenceor pitch line
t = Belt thickness
Dp = The diameter of the pulley pitch is obtained from formula Dp = (P · N)/P
De = External diameter of pulley De=Dp – NF
Df = Flange diameter
d = Bore diameter
Dm = Hub diameter
F = Tooth width
L = Total length incl. Hub
