A sprocket is a wheel with tooth, cogs, or even sprockets that mesh with the holes in the links of chain, monitor, or other perforated material. A sprocket is different from a gear because a sprocket by no means meshes directly with another sprocket. Sprockets are made to be planetary gearbox utilized with a specific chain. Selecting the most appropriate sprocket optimizes sprocket/chain interaction, ensures drive functionality, and decreases maintenance.
