This paper studies the influence of macrogeometry and material type of spur gears on their torque capacity, reliability, and acquisition cost. The developed model indicates how costly it is to enhance the torque capacity or the reliability of gears. The results are in agreement with the catalog prices of a manufacturer in a wide size range and different modules. The model provides a simple cost estimation tool for multi-objective gear design and optimization.
