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.
Bicycle chains Roller chain and sprocket. A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it.Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.
Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, [1] passing over a sprocket, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system.
16 tooth sprocket. Do = Sprocket diameter. Dp = Pitch diameter A sprocket and roller chain.

Skip-link chain is an obsolete roller chain for bicycles in which side plates are alternately short and long, and so rollers are alternately close together and far apart. A skip-link chain running over the rear sprocket on a bicycle. In bicycle chains, skip-link chain has the same one-inch spacing as the earlier block chain. Due to the ...
