Research On NGW-S Planetary Gearbox CAD Parametric Design

Based on the characteristic of NGW-S type planetary gear reducer, the objective function whose volume is the smallest is put up. In the restrained condition, the principle of equal-strength is taken to our mind that makes the gear bent strength and contact strength to be considered comprehensively.The system has accomplished design compute through C++bulider program language for NGW-S type planetary gear reducer, accomplished Feature Modeling of most of parts of NGW-S type planetary gear reducer used the Feature Modeling technology of Pro/ENGIEER software on the research object of NGW-S type planetary gear reducer, realized the parametric design and assembly design of NGW-S type planetary gear reducer, thus has realized design calculation and product model combines with nothing seam. The task work has developed one set of NGW-S type planetary gear reducer CAD's system of collection design, model building, assembly animation and possesses the important meaning to raise the design standard of the NGW-S type planetary gear reducer.
