A sprocket is a wheel with the teeth, cogs, or even sprockets that mesh with the holes in the links of chain, monitor, or other perforated materials. A sprocket differs from a gear just because a sprocket by no means meshes straight with another sprocket. Sprockets are designed to be utilized with a planetary gearbox specific chain. Choosing the right sprocket optimizes sprocket/chain interaction, ensures drive overall performance, and decreases maintenance.
