SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize a perfect engagement mechanism, and may continue to keep a noise level remarkably reduce than typical roller chains.
SC kind silent chains is often utilized for large velocity and massive stress transmission much like a toothed metallic belt because the plates immediately engage with the sprockets for driving.
SCR-04 silent chains are built with inner engaging structure for further reduced noise level.
PS silent chain
A PS form silent chain includes a structure in which a set of specially formed connecting pins and locker pins get in touch with every single other although rotating at just about every flexible bearing place. Thus, it generates much less heat specially in higher velocity operation and it is fantastic in sturdiness. On top of that, the specially formed pins drastically lessen shock once the chain is engaged with sprockets, supplying a larger silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth varieties for that SCA 04××, SC 25××, SC 06×× to the prior webpage and PS silent chains to make sure silent high velocity operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
