SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to attain an ideal engagement mechanism, and can preserve a noise degree remarkably lower than conventional roller chains.
SC variety silent chains may be employed for high velocity and big stress transmission similar to a toothed metallic belt since the plates directly engage with all the sprockets for driving.
SCR-04 silent chains are created with inner engaging structure for more lowered noise level.
PS silent chain
A PS sort silent chain has a structure during which a set of specially formed connecting pins and locker pins get hold of each other even though rotating at just about every versatile bearing position. Hence, it generates much less heat specifically in higher speed operation and it is exceptional in sturdiness. Additionally, the specially formed pins enormously cut down shock once the chain is engaged with sprockets, providing a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× about the prior webpage and PS silent chains to ensure silent large velocity operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
