The possibility of creating molecular gears able to transfer motion has opened novel routes to implement true molecule-based mechanical analogs of computational machine. Here, we use a classical description of rigid molecules to investigate the dynamics of coupled gears for different arrangement and in presence of disorder. To be specific, we consider two gears and many gears problem; Then we demonstrate the solution analytically and numerically. In particular, we focus on the question of transfer of angular momentum acting on assembly of gears, which is relevant in light of recent experiments.
