| Abstract | ||
| Recently, there has been an increasing interest in the development of bicycles speed changers. Multi-speed changers allow cyclists to pedal at their most efficient pace at different road conditions. In this paper, a modified solution technique based on a flawed previous one is presented to investigate the kinematics, the torque distributions and the power flow through one-degree of freedom planetary gear trains. Nomographs are used as a design tool to enable the designer to simultaneously visualize these one-degree of freedom variables without first selecting a particular PGT and without the need to solve equations repeatedly. After that, these techniques will be applied to design a three-speed automatic speed changer. Three design examples are demonstrated to illustrate this modified methodology. | ||
