Geek-of-All

The biggest difference between a sprocket and a gear is how each works on a functional level. Both tend to be grooved wheels used in machinery, and their basic appearance is often really similar — but how they operate and what, exactly, it is they do tends to be really different. In general, a gear is a toothed wheel designed to mesh with other gears and transmit movement to them , which in turn can cause movement elsewhere. A sprocket, conversely, is a toothed wheel designed to engage and directly move a flexible indented or perforated item, like a chain or belt. The applications of each are different as a result. Sprockets are most common when there’s a moving belt or chain that is contained, as is commonly the case in bicycles, conveyor belts, and film projection reels. Gears are typically preferable in all other scenarios, cars and heavy machinery included. Not only are gears more universally useful, but they also aren’t as likely to need repairs or re-fittings...
