Bolt Circle With Odd Number of Holes Within Circle
Measurement and Conversion Calculator #3

For more quations and illustrative graphics see:
Measuring Large Bolt Circle Equations and Review To measure the unknown distance x over semi-opposite holes using pins (largest gage pins that can fit into holes) and the number of holes n is odd and greater than 3, and the distance c between adjacent holes (pins) is known as shown left in Illustration C, use the equation: Where:

c = the distance over adjacent pins
d = the diameter of the holes
θ = 360°/n or angle between adjacent holes.

All units shall be consistant and given in inches or mm. Angles (theta) are given in degrees

 Variables Distance over alternate pins (c) =?? Diameter of holes (d) = Angle between adjacent holes (Theta) = Results Distance over opposite pins (x) =  © Copyright 2000 - 2019, by Engineers Edge, LLC www.engineersedge.com Membership Register | Login   Home Engineering Book Store Engineering Forum Excel App. Downloads Online Books & Manuals Engineering News Engineering Videos Engineering Calculators Engineering Toolbox GD&T Training Geometric Dimensioning Tolerancing DFM DFA Training Training Online Engineering Advertising Center Copyright Notice
