Applied Methodology for Designing and Calculating a Family of Spur Gear Pumps

The paper presents in an applicative manner a parameter-based methodology about design, modeling and optimization of spur gear pump, currently under production Romanian company. Wanting to expand their product range, the company asked for design this type FEM simulations its conception cover wider range flow rates, as required by current beneficiaries. purpose research was find improved alternative solutions via parametric mathematical validation finite element simulation manufacturing solutions. pump model is well known has been manufactured decades many countries, various licenses constructive variants. process analyzed functional role structure, 3D model, which reconstructed from last solution, while identifying certain dimensions be optimized used relations. author CATIA V5 software Visual Basic programing language. By computation, there were identified pressure values forces generated pump’s gears, applied later check behavior components at loads these pressures. identifies summary table maximum stress values, deformations percentages computation errors each solution.
