SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to achieve an ideal engagement mechanism, and can hold a noise degree remarkably reduced than traditional roller chains.
SC variety silent chains may be employed for large velocity and huge tension transmission similar to a toothed metallic belt because the plates immediately engage using the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for further reduced noise degree.
PS silent chain
A PS sort silent chain includes a construction by which a set of specially formed connecting pins and locker pins speak to just about every other even though rotating at each and every flexible bearing position. So, it generates less heat particularly in substantial speed operation and it is superb in sturdiness. On top of that, the specially formed pins drastically lessen shock when the chain is engaged with sprockets, giving a larger silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth forms for the SCA 04××, SC 25××, SC 06×× on the earlier web page and PS silent chains to be sure silent high speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
