SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to attain a perfect engagement mechanism, and may maintain a noise degree remarkably reduce than typical roller chains.
SC variety silent chains could be utilized for large pace and big stress transmission similar to a toothed metallic belt since the plates straight engage with the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for even further reduced noise level.
PS silent chain
A PS type silent chain features a structure in which a set of specially formed connecting pins and locker pins speak to each and every other although rotating at every versatile bearing place. Thus, it generates much less heat primarily in high velocity operation and is superb in sturdiness. On top of that, the specially formed pins enormously reduce shock when the chain is engaged with sprockets, supplying a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt particular modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× on the former web page and PS silent chains to be sure silent large pace operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
