ABSTRACT

This paper presents an analytical process for predicting the mechanical efficiency of bicycle internal drive hubs composed of planetary gear mechanisms. An existing 14-speed internal drive hub is introduced and is taken as an example to demonstrate the analytical process. Kinematic analysis, static torque analysis, power flow analysis and mechanical efficiency analysis of this internal drive hub are illustrated by applying the fundamental circuit method.
