Helical gear pitch diameter formula
WebThe pitch circle diameter, PCD, will be: PCD = n * mod The outside diameter of the gear is OD In the metric system OD is – OD = (number of teeth + 2) * MOD In the imperial system OD is OD = (number of teeth + 2) / DP Circular pitch is the space between one tooth and the next on the pitch circle. In the metric system this is CP = Mod * pi WebStandard modules for straight and helical gears are defined by ISO 54:1996 and indicate the amount of pitch diameter (or pitch length, in the case of a straight rack) that each …
