SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to attain a great engagement mechanism, and will retain a noise level remarkably lower than standard roller chains.
SC form silent chains is often made use of for high 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 intended with inner engaging construction for more lowered noise level.
PS silent chain
A PS variety silent chain has a structure by which a set of specially formed connecting pins and locker pins get hold of each other while rotating at each and every versatile bearing place. Hence, it generates significantly less heat particularly in high velocity operation and is outstanding in sturdiness. Moreover, the specially formed pins tremendously lower shock once the chain is engaged with sprockets, supplying a larger silencing impact than SC silent chains.
Sprockets for silent chains adopt special modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× on 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.
