SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to attain an ideal engagement mechanism, and might continue to keep a noise degree remarkably reduce than conventional roller chains.
SC kind silent chains might be used for high pace and substantial tension transmission much like a toothed metallic belt since the plates right engage using the sprockets for driving.
SCR-04 silent chains are intended with inner engaging framework for additional diminished noise level.
PS silent chain
A PS type silent chain has a construction in which a set of specially formed connecting pins and locker pins get in touch with each other even though rotating at each and every versatile bearing position. Consequently, it generates significantly less heat specially in substantial speed operation and is fantastic in sturdiness. Additionally, the specially formed pins significantly reduce shock once the chain is engaged with sprockets, delivering a greater silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× within the preceding web page and PS silent chains to make certain silent large speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
