What is the pitch circle diameter of a 50-tooth spur gear having a circular pitch of 0.375 inch

Pitch circle diameter = 5,66 inch

Explanation:

According to the pitch circle diameter formula

      Dc= Dp - 2b ; where Dp= primitive diameter, b= dedendum of the tooth and also the dedendum formula is b= 1,25 Pc/π.

     The definition of primitive diameter is equal to (Pc*Z)/π ; Pc= circular pitch and Z= number of teeths.

    Replacing in the formula

        ⇒ Dc= (Pc*Z)/π - 2* 1,25 Pc/π,    Pc= 0,375 ; Z=50

  In conclusion the pitch circle diameter is equal to:

            Dc= 5,66 inch.
