SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to achieve a great engagement mechanism, and might preserve a noise level remarkably decrease than typical roller chains.
SC style silent chains can be applied for large velocity and huge stress transmission much like a toothed metallic belt because the plates right engage with the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for even further decreased noise level.
PS silent chain
A PS type silent chain includes a structure in which a set of specially formed connecting pins and locker pins get hold of each other although rotating at each flexible bearing place. As a result, it generates less heat specifically in large speed operation and it is fantastic in sturdiness. Additionally, the specially formed pins significantly reduce shock when the chain is engaged with sprockets, giving a greater silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth forms to the SCA 04××, SC 25××, SC 06×× about the preceding webpage and PS silent chains to guarantee silent high pace operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
