SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to accomplish a great engagement mechanism, and might continue to keep a noise level remarkably reduced than typical roller chains.
SC type silent chains could be applied for higher speed and substantial tension transmission just like a toothed metallic belt because the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are created with inner engaging construction for even further decreased noise degree.
PS silent chain
A PS variety silent chain includes a framework by which a set of specially formed connecting pins and locker pins speak to each other while rotating at just about every flexible bearing place. Consequently, it generates less heat primarily in high pace operation and it is excellent in durability. Additionally, the specially formed pins greatly decrease shock when the chain is engaged with sprockets, providing a increased silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× within the preceding webpage and PS silent chains to make sure silent large pace operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
