SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to accomplish a perfect engagement mechanism, and will maintain a noise level remarkably lower than standard roller chains.
SC variety silent chains is usually employed for high speed and substantial stress transmission just like a toothed metallic belt since the plates right engage using the sprockets for driving.
SCR-04 silent chains are created with inner engaging construction for additional diminished noise level.
PS silent chain
A PS type silent chain has a structure during which a set of specially formed connecting pins and locker pins speak to just about every other although rotating at every single versatile bearing position. Thus, it generates less heat primarily in higher velocity operation and it is superb in sturdiness. Furthermore, the specially formed pins tremendously cut down shock when the chain is engaged with sprockets, supplying a higher silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× around the earlier web page and PS silent chains to ensure silent large speed operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
