SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and particular plates to accomplish an excellent engagement mechanism, and may keep a noise level remarkably lower than conventional roller chains.
SC form silent chains may be employed for higher velocity and massive tension transmission much like a toothed metallic belt because the plates right engage with all the sprockets for driving.
SCR-04 silent chains are built with inner engaging structure for more diminished noise degree.
PS silent chain
A PS style silent chain features a structure through which a set of specially formed connecting pins and locker pins get hold of each and every other though rotating at each flexible bearing place. As a result, it generates significantly less heat in particular in large velocity operation and is outstanding in sturdiness. Furthermore, the specially formed pins tremendously minimize shock once the chain is engaged with sprockets, delivering a increased silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth types for the SCA 04××, SC 25××, SC 06×× over the preceding web page and PS silent chains to ensure silent large velocity operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
