Abstract: Bevel gears are used in developing new type of power distribution box driven by single force. The device needs high precision gears which are hard to accomplish by traditional design. So gears designed by using Solid Edge can be directly processed by NC manufacturing after modeling and will be improved both in their precision and carrying capacity without changing parameters and materials. The research is based on the combination of Solid Edge and Excel. The method of design can be used in various bevel gears in power distribution box and also has a reference value for modeling of complicated parts.

Key words: computer application, parameterized modeling, collaborative computing, straight bevel gear
