SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to achieve a perfect engagement mechanism, and might continue to keep a noise level remarkably decrease than traditional roller chains.
SC kind silent chains might be utilised for high velocity and large stress transmission similar to a toothed metallic belt since the plates right engage with the sprockets for driving.
SCR-04 silent chains are designed with inner engaging construction for additional diminished noise level.
PS silent chain
A PS variety silent chain features a construction during which a set of specially formed connecting pins and locker pins get hold of every other when rotating at each and every versatile bearing position. So, it generates much less heat specially in high pace operation and it is fantastic in sturdiness. Moreover, the specially formed pins tremendously minimize shock when the chain is engaged with sprockets, offering a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× on the earlier web page and PS silent chains to make certain silent higher velocity operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
