SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to achieve an excellent engagement mechanism, and may maintain a noise level remarkably reduce than standard roller chains.
SC type silent chains can be made use of for large speed and massive stress transmission just like a toothed metallic belt because the plates directly engage together with the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for further reduced noise degree.
PS silent chain
A PS sort silent chain has a framework in which a set of specially formed connecting pins and locker pins speak to every single other even though rotating at just about every versatile bearing position. As a result, it generates much less heat primarily in high velocity operation and is great in durability. In addition, the specially formed pins enormously lower shock once the chain is engaged with sprockets, supplying a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt particular modules in involute tooth types for the SCA 04××, SC 25××, SC 06×× on the prior webpage and PS silent chains to ensure silent substantial speed operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
