SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and particular plates to accomplish an excellent engagement mechanism, and can maintain a noise level remarkably decrease than traditional roller chains.
SC type silent chains could be used for high pace and massive tension transmission just like a toothed metallic belt because the plates right engage together with the sprockets for driving.
SCR-04 silent chains are designed with inner engaging framework for even more diminished noise level.
PS silent chain
A PS style silent chain features a framework through which a set of specially formed connecting pins and locker pins contact just about every other although rotating at just about every flexible bearing position. Thus, it generates significantly less heat particularly in high velocity operation and is outstanding in durability. Furthermore, the specially formed pins considerably lessen shock when the chain is engaged with sprockets, offering a larger silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth varieties to the SCA 04××, SC 25××, SC 06×× to the prior page and PS silent chains to ensure silent substantial speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
