Abstract
This paper describes a Computer Aided approach to the design of the epicyclical gear system. It aims, to determinate all geometrical and kinematic parameters of an epicyclical gear train system with spur gears, such as the number of teeth of each gear, the global calculation of spur gears profile, the transmission ratio, the function of volume and the global weight of the planetary gear system. It also provides the selection of optimal concept of the planetary gear train in order to satisfy the assembly and the balance conditions, the drafting of the sun and the planets gears. This approach applies standard design equations on spur gears and the balance constraints of the epicyclical gears system. It links them together using a programming language (C#) in order to develop a special application or computer-aided design named Planetary Gear Train Calculator (PGTC). This study presents the algorithms involved in the design of the epicyclical gear system and the development of the aided computer design. Using this approach facilitates the calculation of design parameters and the drafting of the spur gears, which gives a big choice of the perfect concept of the epicyclical gear train with a different number of planets. The computer program has been tested successfully and evaluated compared to the manual calculation. In the last part of the present paper, an example of the application of the PGTC has been illustrating.
