Sprockets

Sprockets, sometimes referred to as sprocket-wheels or toothed wheels, drive the mechanical power in a chain drive. Any wheel design which has radial projections and meshes with a chain or track is known as a sprocket. Unlike gears, sprockets are not directly meshed together. Unlike pulleys, which are smooth, sprockets have teeth. Sprockets enable rotary motion between two shafts or linear motion. Sprockets come in various designs and types to enable maximum efficiency in particular applications. Sprockets can be in chain sprocket or plate wheel versions and in simplex, duplex and triplex styles. The two main types of sprockets are pilot bore and taper bore. Sprockets can be constructed from various materials, including steel, stainless steel, cast iron and nylon. Sprockets need to be made to the relevant British Standards, such as DIN8187 ISO/R606. As sprockets can be used in bore, grubscrew and keyway machining options and are extremely versatile. The most common use of sprockets is in bicycle chains but they are also used in the caterpillar tracks of large outdoor vehicles as well as whole host of other machine applications.
