The Addendum Circle Diameter of Spur Gear is defined as a circle touching the outermost points of the teeth of a circular gear wheel. It represents the maximum diameter of the gear including the tooth addendum.
The calculator uses the formula:
Where:
Explanation: The addendum circle diameter is calculated by adding twice the addendum value to the pitch circle diameter, accounting for the tooth height on both sides of the gear.
Details: Accurate calculation of addendum circle diameter is crucial for gear design, manufacturing, and ensuring proper meshing between gears. It determines the outer dimensions of the gear and affects clearance requirements in gear assemblies.
Tips: Enter pitch circle diameter and addendum values in meters. Both values must be positive numbers. The calculator will compute the addendum circle diameter based on the input parameters.
Q1: What is the difference between pitch circle and addendum circle?
A: The pitch circle is the theoretical circle where gear teeth effectively mesh, while the addendum circle is the outer circle that touches the tips of the gear teeth.
Q2: Why is addendum important in gear design?
A: Addendum determines the height of the tooth above the pitch circle and affects the gear's strength, contact ratio, and overall performance.
Q3: Can this formula be used for all types of gears?
A: This specific formula is primarily used for spur gears. Other gear types (helical, bevel, worm) may have different calculation methods.
Q4: What units should be used for input values?
A: The calculator uses meters for all dimensions, but you can use any consistent unit system as long as all inputs are in the same units.
Q5: How accurate is this calculation?
A: The calculation is mathematically precise based on the input values. The accuracy of the result depends on the accuracy of the input measurements.
