Gas-cooling Vacuum Pump Silent chain, or inverted-tooth 
chain, can be a type of chain with teeth formed on its links to engage with one’s teeth in the sprockets. Silent chains drives are not really silent. The links in a silent chain drive, however, engage with the sprocket tooth with little impact or sliding, and consequently a silent chain creates less vibrations and sound than various other chains. The amount of noise generated by a silent chain drive depends of many factors including sprocket size, velocity, lubrication, load, and drive support. A web link belt silent chain contains removable links became a member of by rivets or interlocking tabs. These chains provide advantage of installation without dismantling drive elements, reducing inventory, and increasing temperature ranges
