A chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, 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. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. Sometimes the pow…

In aeronautics, an aircraft propeller, also called an airscrew, is an aircraft propulsion device that converts rotary motion from an engine or other power source into a swirling slipstream that generates thrust. A typical propeller engine comprises the motor driving a rotating shaft (driveshaft), to which several radial airfoil-section blades are attached, so that the whole blade assembly (i.e. the propeller) rotates around an axis of rotation longitudinal to the direction of travel. The propeller blades, which can be made from wood, metal or composite materials, attaches to the driveshaft either directly or through reduction gearing, and the blade pitch may be fixed, manually variable to a…

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. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission. Sketches by Leonardo da Vinci in the 16th century show a chain with a roller bearing. In 1800, James Fussell patented a roller chain on development of his balance lock and in 1880 Hans Renold patented a bush r…
