Pitch Circle Diameter of Studs Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pitch Circle Diameter of Engine Stud = Inner Diameter of Engine Cylinder+3*Nominal Diameter of Cylinder Head Stud
D_p = D_i+3*d
This formula uses 3 Variables

Variables Used

Pitch Circle Diameter of Engine Stud - (Measured in Meter) - Pitch Circle Diameter of Engine Stud is the diameter of the circle which passes through the center of all the studs.
Inner Diameter of Engine Cylinder - (Measured in Meter) - Inner Diameter of Engine Cylinder is the diameter of the interior or the inside surface of an engine cylinder.
Nominal Diameter of Cylinder Head Stud - (Measured in Meter) - Nominal Diameter of Cylinder Head Stud is the smallest diameter of the thread of an engine cylinder head stud.

STEP 1: Convert Input(s) to Base Unit

Inner Diameter of Engine Cylinder: 128.5 Millimeter --> 0.1285 Meter (Check conversion here)
Nominal Diameter of Cylinder Head Stud: 23.5 Millimeter --> 0.0235 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D_p = D_i+3*d --> 0.1285+3*0.0235

Evaluating ... ...

D_p = 0.199

STEP 3: Convert Result to Output's Unit

0.199 Meter -->199 Millimeter (Check conversion here)

FINAL ANSWER

199 Millimeter <-- Pitch Circle Diameter of Engine Stud

(Calculation completed in 00.020 seconds)

More on Pitch Circle Diameter

The pitch circle of gear does not physically exist as a form. Consequently, it is not possible to measure it with an instrument. There are various opinions, but for spur gears, it is generally likened to two disks equal to the pitch diameters which are side by side and transmitting power by friction.
The examples of gear terminology related to pitch circles can be listed as pitch circle diameter, meshing pitch circle diameter, outside diameter, root diameter, etc.
