Downsizing gears to the nanoscale has become an emergent technology for implementing microscopic mechanical system. Here, we theoretically investigate how rotational motion can be transmitted across many gears by using molecular dynamics simulations. In particular, the influence of the elastic properties and the shape of the gears is elucidated. Furthermore, we study the effect of friction coming from the substrate and we find that the dissipation is dependent on the gear size and also its initial angular velocity.
