SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to achieve a great engagement mechanism, and may maintain a noise degree remarkably reduce than traditional roller chains.
SC sort silent chains is often applied for high pace and large stress transmission similar to a toothed metallic belt since the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are designed with inner engaging framework for further decreased noise level.
PS silent chain
A PS style silent chain includes a construction through which a set of specially formed connecting pins and locker pins contact every other while rotating at every single versatile bearing place. Consequently, it generates significantly less heat specifically in higher pace operation and is outstanding in durability. Additionally, the specially formed pins considerably cut down shock once the chain is engaged with sprockets, supplying a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× on the past webpage and PS silent chains to ensure silent substantial pace operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
