SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to realize a perfect engagement mechanism, and will hold a noise level remarkably reduced than typical roller chains.
SC variety silent chains might be utilized for high pace and significant tension transmission much like a toothed metallic belt since the plates straight engage with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging framework for more lowered noise level.
PS silent chain
A PS form silent chain includes a structure during which a set of specially formed connecting pins and locker pins contact each other while rotating at every flexible bearing place. Thus, it generates less heat particularly in higher pace operation and it is superb in sturdiness. On top of that, the specially formed pins significantly decrease shock when the chain is engaged with sprockets, delivering a increased silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth varieties to the SCA 04××, SC 25××, SC 06×× within the preceding page and PS silent chains to make certain silent higher velocity operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
