· Belt drive, chain drive and rope drive are examples of flexible drive due to presence of belt, chain and rope, respectively as intermediate linkage between two shafts. Such linkage introduces flexibility in the drive unit and thus they can be utilized for long distance power transmission. On the other hand, when no such intermediate linkage exist then that .
Drive shafts are another common method used to move mechanical power around that is sometimes evaluated in comparison to chain drive; in particular belt drive vs chain drive vs shaft drive is a key design decision for most motorcycles. Drive shafts tend to be tougher and more reliable than chain drive, but the bevel gears have far more friction than a chain. For this .
