碩士 === 國立中央大學 === 機械工程研究所 === 97 === Because the design procedure for the mature product gearbox is almost unaltered, the designers are engaged in routine tasks for developing new gearboxes. The cost for development and design of gearboxes might be reduced if the routine works can be replaced by software. The aim of the thesis is to establish program modules for gearbox from a developed software based on the concept of object orient programming. The modules that integrate both calculation and graphics of gearbox design offer also the benefits in simplifying the complexities of the design software for gearboxes as well as in expanding the application range of such a software. The object oriented programming modules are at first established with aid of analysis of the important machine elements of gearboxes and their corresponding design procedures. The modules not only offer the calculation for deigning the elements such like gears and bearings, but also generate the 3D-solid models of the related machine elements and assembly by using the CAD software Autodesk Inventor. Finally based on the OOP method RUP (Rational Unified Process), two programs using the modules are developed for different gearboxes: standard helical gearboxes and single screw extruder gearboxes. The expected goals of the developed program modules are verified by the mentioned examples.
