SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to achieve a great engagement mechanism, and might preserve a noise level remarkably reduced than standard roller chains.
SC type silent chains could be utilised for higher speed and large tension transmission much like a toothed metallic belt because the plates right engage with all the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for even further decreased noise degree.
PS silent chain
A PS kind silent chain has a structure by which a set of specially formed connecting pins and locker pins make contact with just about every other even though rotating at every single versatile bearing place. Thus, it generates much less heat specifically in substantial velocity operation and it is outstanding in durability. Additionally, the specially formed pins enormously lessen shock once the chain is engaged with sprockets, providing a higher silencing effect than SC silent chains.
Sprockets for silent chains adopt specific modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× about the preceding page and PS silent chains to ensure silent higher velocity operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
