SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize an ideal engagement mechanism, and can continue to keep a noise degree remarkably reduce than standard roller chains.
SC sort silent chains might be utilized for high speed and significant tension transmission just like a toothed metallic belt since the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are created with inner engaging framework for additional diminished noise degree.
PS silent chain
A PS variety silent chain features a framework during which a set of specially formed connecting pins and locker pins make contact with every single other though rotating at each and every versatile bearing position. Thus, it generates much less heat primarily in high pace operation and is outstanding in durability. Moreover, the specially formed pins considerably lessen shock once the chain is engaged with sprockets, supplying a larger silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× on the previous page and PS silent chains to make sure silent large speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
