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 ...
A chain drive and rear derailleur gear change, the most popular system in use today A shaft-drive with crankset and rear gear hub. Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels.
Shaft-drive: alternate to chain-drive; Shifter: gear shifting control; Shock absorber: for bicycles with suspensions, a device that limits the rate at which suspension rebounds after absorbing an impact; Side view mirror: aids in looking at the sides prior to moving slowly or turning to the left or to the right
In a chain-drive, the power is transmitted into the rear wheel via a cush drive. Conventional roller chain-drives suffer the potential for vibration, as the effective radius of action in a chain and sprocket combination constantly changes during the revolution ("chordal action"). If a drive sprocket rotates at constant RPM, then the chain (and ...
For motorcycles with chain drive, the gearbox output shaft is typically connected to the sprocket which drives the final drive chain. Most modern manual motorcycle gearboxes have "constant-mesh" gears which are always mated but may rotate freely on a shaft until locked by a toothed sliding collar, or " dog clutch ".
Chain track drive sprocket (Leclerc battle tank, 2006) In the case of vehicles with caterpillar tracks the engine-driven toothed-wheel transmitting motion to the tracks is known as the drive sprocket and may be positioned at the front or back of the vehicle, or in some cases both. There may also be a third sprocket, elevated, driving the track.

Roller chain and sprocket The sketch of roller chain, Leonardo da Vinci, Codex Atlanticus. Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles.
