SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to attain a perfect engagement mechanism, and can retain a noise degree remarkably decrease than typical roller chains.
SC style silent chains might be utilised for large speed and huge tension transmission similar to a toothed metallic belt because the plates right engage with all the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for additional reduced noise degree.
PS silent chain
A PS form silent chain has a framework through which a set of specially formed connecting pins and locker pins contact every other even though rotating at just about every versatile bearing position. So, it generates much less heat specifically in substantial pace operation and it is exceptional in sturdiness. Furthermore, the specially formed pins considerably cut down shock once the chain is engaged with sprockets, providing a higher silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth types for the SCA 04××, SC 25××, SC 06×× around the earlier webpage and PS silent chains to ensure silent higher speed operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
