The Pitch Circle Diameter is the diameter of a circle which by a pure rolling action would transmit the same motion as the actual gear wheel. It should be noted that in the case of wheels which connect non-parallel shafts, the pitch circle diameter is different for each cross section of …... used for calculation of the gear heel pitch diameter. Often, the gear drawing provides the heel pitch diameter. However, the module is often given in normal to the tooth spiral. It is called normal module. Transversal module can be calculated from normal module and spiral angle. But finding a spiral angle on the heel is often not easy from the drawing. The best way to calculate the pitch

### Pitch diameter is the diameter of a pitch circle. The standard (reference) pitch circle is defined as: “The circle which intersects the involute at the point where the pressure angle is equal to the profile angle of the basic rack.” The stan-dard pitch diameter, D, is the diameter of this standard (reference) pitch circle and is obtained by D = N/P d or—in the metric or—in the metric

- Calculate and draw the Pitch Circle. The Diameter of the Pitch Circle is calculated below; a. P N D = 1.5" 24 36 D = = 2. Calculate and draw the Root Circle. The formula to determine the Root Circle Diameter is given below; a. P N RD −2 = = 24 36−2 RD = = 24 34 RD = = 1.416” 3. Calculate and draw the Outside Circle. The formula to determine the Outside Circle Diameter is given below; a
- The Pitch Diameter refers to the diameter of the pitch circle. If the gear pitch is known then the Pitch Diameter is easily calculated using the following formula; P N PD = Using the values from fig. 6.3.1.3 we find 1.5" 24 36 P N PD = = = The Pitch Diameter is used to generate the Pitch Circle. Fig. 6.3.1.3 DP = #Teeth/Pitch Diameter = 36/1.5 = 24 Fig. 6.3.1.4 Relative Sizes of Diametral
