Model: V03 Belt Drive with Variable Axle Direction Pulleys
In this belt drive mechanism, the input and output axes can be set at arbitrary angles to one another. The belt is guided by a single intermediary pulley with a crowned radius to assist self alignment. The position of this intermediate pulley is also adjustable. Belt and cable drives were common in the 19th century to distribute power from a central prime mover such as a steam engine. Today cable and pulley mechanisms are part of cablecar and lift systems to carry people up to high mountain terrains.
