SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to accomplish an excellent engagement mechanism, and may retain a noise degree remarkably lower than conventional roller chains.
SC kind silent chains can be employed for substantial pace and big stress transmission just like a toothed metallic belt since the plates right engage with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for even further reduced noise degree.
PS silent chain
A PS form silent chain has a construction during which a set of specially formed connecting pins and locker pins contact every single other while rotating at just about every versatile bearing position. So, it generates less heat especially in higher pace operation and it is superb in sturdiness. In addition, the specially formed pins tremendously lessen shock once the chain is engaged with sprockets, supplying a larger silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× about the preceding page and PS silent chains to be sure silent large velocity operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
