A sprocket is a mechanical element shaped like a toothed disk which, together with a chain, is used for the transmission of power as part of a drive system. There are two basic types of sprockets.
The first type is the classic sprocket with gear-like teeth which transfers power via roller chains. This is the type used in chain drives. The sprocket gear and the chain form a drive mechanism to harness and transmit power. A typical example of this is the chain drive of a bicycle. It is important that the sprocket teeth fit into the roller chain links precisely and smoothly so that the required driving power can be generated. These sprockets are standardized in accordance with DIN 8192 and are usually designed as disks, sometimes having a flange on one side. The minimum number of teeth is 15, otherwise the chain drive would not function smoothly and vibration would occur.
Depending on loads and intended usage, these sprockets can be designed as single, dual or triple sprocket gears. Dual and triple chain drives are more suited for handling high levels of traction.
These chains are commonly used in the automotive sector to drive camshafts.
Sprockets made of steel or brass are typically used for this purpose.
Sprockets are also used with link chains. These sprockets differ in form and shape as well as sprocket size, and they are made of steel or stainless steel.
