SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to realize a perfect engagement mechanism, and can preserve a noise degree remarkably decrease than standard roller chains.
SC variety silent chains is often employed for large speed and substantial tension transmission much like a toothed metallic belt since the plates straight engage with the sprockets for driving.
SCR-04 silent chains are made with inner engaging structure for even more decreased noise degree.
PS silent chain
A PS form silent chain features a framework in which a set of specially formed connecting pins and locker pins make contact with every single other even though rotating at just about every flexible bearing position. Consequently, it generates significantly less heat specifically in large velocity operation and is fantastic in durability. Moreover, the specially formed pins tremendously minimize shock when the chain is engaged with sprockets, providing a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth types for the SCA 04××, SC 25××, SC 06×× about the earlier web page and PS silent chains to make sure silent large speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
