Based on the analysis of structural characteristics of cone column diagonal gear reducer, using PRO/ E,the three - dimensional modeling design and mechanism simulation of cone column diagonal gear reducer were designed, offered a favorable tool for reducer design.

Study on the Design of Cylindrical Gear Reducer Based on Virtual Prototyping Technology;

A discussion is made of the definition of reliability, items to be examined, and models of fault tree for cylindrical gear reducers.

This paper uses the parameterized function of the Pro/E software to give one way of parameterized modeling for the lower-case of cylindrical gear reducer.

The multi-object reliability optimization design model of helical gear reducer which is different from exiting ones is built while minimum volume and wear of helical gears are taken as the objective functions.

In the paper,by using knowledge of reliability design theory and modern optimization technology,the method is studied about how the mathematical reliability optimization model of the single helical gear reducer is built while the minimum volume of helical gears is taken as the objective function and an optimization design model of a reducer used in an engineering real example is built.
