SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to achieve an ideal engagement mechanism, and may continue to keep a noise level remarkably decrease than standard roller chains.
SC form silent chains is usually applied for large pace and significant stress transmission just like a toothed metallic belt since the plates directly engage using the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for even further diminished noise level.
PS silent chain
A PS kind silent chain features a framework during which a set of specially formed connecting pins and locker pins contact each and every other while rotating at each versatile bearing place. Hence, it generates less heat especially in high velocity operation and is great in sturdiness. Additionally, the specially formed pins tremendously cut down shock once the chain is engaged with sprockets, giving a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth types for that SCA 04××, SC 25××, SC 06×× about the prior page and PS silent chains to guarantee silent higher speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
