SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to accomplish an ideal engagement mechanism, and can preserve a noise level remarkably reduce than standard roller chains.
SC form silent chains can be made use of for large speed and huge stress transmission just like a toothed metallic belt since the plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for even further diminished noise degree.
PS silent chain
A PS form silent chain includes a construction through which a set of specially formed connecting pins and locker pins make contact with just about every other whilst rotating at every single flexible bearing position. Hence, it generates significantly less heat specifically in substantial pace operation and it is great in sturdiness. On top of that, the specially formed pins significantly lessen shock once the chain is engaged with sprockets, delivering a increased silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth varieties for that SCA 04××, SC 25××, SC 06×× about the preceding page and PS silent chains to ensure silent substantial pace operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
