SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to attain an excellent engagement mechanism, and may maintain a noise level remarkably reduced than traditional roller chains.
SC sort silent chains is usually employed for high velocity and substantial tension transmission similar to a toothed metallic belt because the plates immediately engage together with the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for even more decreased noise level.
PS silent chain
A PS variety silent chain has a structure during which a set of specially formed connecting pins and locker pins get in touch with each and every other whilst rotating at every versatile bearing place. As a result, it generates much less heat primarily in substantial speed operation and it is excellent in durability. Furthermore, the specially formed pins tremendously minimize shock once the chain is engaged with sprockets, providing a higher silencing impact than SC silent chains.
Sprockets for silent chains adopt specific modules in involute tooth types for that SCA 04××, SC 25××, SC 06×× around the preceding page and PS silent chains to make certain silent higher speed operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
