Chain, series of links, generally of metal, joined jointly to form a flexible connector for various purposes, such as keeping, pulling, hoisting, hauling, conveying, and transmitting power.
The easiest and oldest kind of chain is the coil chain, which is manufactured out of straight metal bars that are bent to an oval shape, looped together, and welded shut. These bars were traditionally made of wrought iron, but chains manufactured from metal have gained favour recently. This kind of chain was typically used in slings, cranes, and power shovels, nonetheless it provides partly been changed by cable or wire rope. On some hoists, coil chains run on special pulleys with recesses where the chain matches. A variant of the coil chain is the stud-link chain, each of whose links has a bar or stud across its inside width. These studs add weight, keep the chain from fouling or kinking, and assist in preventing deformation; stud-link chains are preferred for use as anchor and cable chains on ships.
A silent chain is essentially an assemblage of equipment racks, each with two the teeth, pivotally connected to form a closed chain. The links are pin-connected, flat steel plates with directly tooth. Silent chains are quieter than roller chains, can operate at higher speeds, and may transmit more load for the same width.
Silent chain comprises stacked rows of smooth, tooth shaped driving links that mesh with sprockets having compatible tooth spaces. Silent chains contain guide links to maintain proper tracking on sprockets. Spacers and washers could also within some silent chain constructions. The silent chain is certainly held collectively by riveted pins positioned in each chain joint. All silent chains possess these basic features but there are many different styles, designs, and configurations.

Silent chain is utilized in both power transmission and conveying applications. It is important to recognize the application when considering purchasing silent chain. Silent chain is definitely available center guided, part guided or with two center guides. It is available with single pin or two pin joints. It is important to note the pitch and width when identifying silent chain, and also the build type. Silent chains are found in a variety of demanding commercial and automotive applications, especially those industries needing high speeds and quiet operation.
Silent chain, or inverted-tooth chain, is a type of chain with teeth formed upon its links to activate with one’s teeth in the sprockets. Silent chains drives are not truly silent. The links in a silent chain drive, however, engage with the sprocket tooth with little impact or sliding, and as a result a silent chain generates less vibrations and noise than various other chains. The amount of noise produced by a silent chain drive is dependent of many factors including sprocket size, rate, lubrication, load, and drive support. A web link belt silent chain includes removable links became a member of by rivets or interlocking tabs. These chains offer the advantage of set up without dismantling drive elements, reducing inventory, and increasing temperature ranges.
Pitch
A silent chain’s pitch is normally expressed in inches; the most common are .375 in, .500 in, .750 in, 1.000 in, 1.500 in, and 2.000 in. Chain pitch can be determined by measuring distance over the consecutive pin heads and dividing by three. Width is also used to express the size of a silent chain which includes: width over heads (the maximum chain width, measured over the ‘headed’ pins), width over links (the measurement across link plates, excluding pin heads or washers), width between guides (measured between guidebook plates; used just with side information silent chains), and nominal width (not a measurement, but an approximation of chain sized for catalogs).

Applications
Silent chain can be used in a number of power transmission and conveying applications. When found in power transmission applications, silent chains can transmit loads at speeds more than other styles of chains and belts. Furthermore, silent chain drives transmit power more efficiently and with less noise and vibration. Silent chains are also used in conveying applications because their conveying surface is durable, resistant to heat, is flat, and non-slip. Silent chains from different manufactures are different in design; parts shouldn’t be used interchangeably.
