SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to achieve an excellent engagement mechanism, and may continue to keep a noise level remarkably reduce than conventional roller chains.
SC style silent chains may be used for substantial speed and huge tension transmission just like a toothed metallic belt because the plates right engage using the sprockets for driving.
SCR-04 silent chains are created with inner engaging framework for additional lowered noise level.
PS silent chain
A PS form silent chain has a structure in which a set of specially formed connecting pins and locker pins contact just about every other whilst rotating at each versatile bearing position. As a result, it generates much less heat specially in substantial speed operation and is exceptional in sturdiness. Additionally, the specially formed pins significantly cut down shock when the chain is engaged with sprockets, delivering a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth varieties for that SCA 04××, SC 25××, SC 06×× within the prior page and PS silent chains to make sure silent higher speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
