Reducer is an important telekinesis device extensively used in machine technology. Its processes of designing are very complicated, dull and overelaborate, because they involve a large amount of calculation and looking up a great number of charts in machine design handbook. At present designers mainly adopt traditional hand-made method, thus design cycle is so long that efficiency is very low. By using visual technology, CAD and CAI technology, the author develops the system software for reducer designing and higher education teaching on WINDOWS platform with visual FoxPro tool. It is proved by experience that the software runs steadily and has reliable results. The software can aid machine design as well as teaching. Its friendly interface can make complicated and dull design become easier,quicker, more exact and more imaginable. The crucial technology used in the process of reducer designing and other designing methods have an important significance and value for developing other CAD/CAI software, therefore the software will have wide application.
