Research And System Realization On The Parameterized Design Of Gear Pumps

Parametric Design technology is an effective way of the rapid enterprises design, and the current mainstream CAD software also realize the parametric function. However, due to the generic functions of CAD software focus on a comprehensive, covering almost every aspect of the manufacturing sector, professional targeted poor, and does not adequately meet the actual design requirements. Parametric design technology has not really played its due benefits. Therefore, general CAD software must be secondary development on its basis, achieve its specialization and localization.This paper has an in-depth study on the parts of the design parameters and made the binding on the assembly of components of the design method. Develop the internal gear pump parametric design system, combining the technology of SolidWorks secondary development.On the gear pump parts parameter optimization, such as gear, transmission shaft, Axial spacing, spline.Established the basic parameter of internal gear pump optimization design model which make the smallest in the body as the objective function and more parts bound for restrictive conditions. And use genetic algorithms to solve the model.Through analysising the mathematical relationship of various gear pump parts between the main parameters and secondary parameters, established correlation parameters function. On this basis, create a gear pump parametric feature model parameters to achieve the components of the programming.Created the database of gear pump assembly and parts, and using ADO technology to manage the database, which implement the operation of various parameters information in the database, such as enquiries, output, modification, delete and preservation.This paper passes through complete gear optimization program, parameter drawing, has shortened the design period of gear pump greatly, has reduced the cost of gear pump, this has positive help for the of gear pump.
