Frequently Asked Questions

What does this calculator calculate?

The Spur Gear Tooth Bending Stress (Lewis Form Factor Method) calculator estimates Bending Stress based on the input parameters you provide

Why is tangential force important in this calculation?

tangential force is directly proportional to bending stress. When you enter tangential force in N, the calculator uses it in the engineering formula to compute the output

How should I interpret the result bending stress?

The calculator outputs bending stress in Pa. For higher pressures, divide by 1000 to express in kPa, or by 101325 for atmospheres. The result is computed directly from the input values using the defined engineering formula

What units should I use for the inputs?

Enter each value in the units shown next to the input field: Tangential Force (N), Diametral Pitch (1/m), Face Width (m), Lewis Form Factor (dimensionless). Make sure all inputs use the specified units for consistent results

What assumptions does this calculator use?

This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
