SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize a great engagement mechanism, and can maintain a noise level remarkably lower than standard roller chains.
SC kind silent chains might be utilised for large pace and large tension transmission just like a toothed metallic belt because the plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for more diminished noise degree.
PS silent chain
A PS sort silent chain includes a structure in which a set of specially formed connecting pins and locker pins speak to just about every other while rotating at every single flexible bearing place. Thus, it generates much less heat primarily in higher velocity operation and it is fantastic in sturdiness. Furthermore, the specially formed pins considerably cut down shock when the chain is engaged with sprockets, giving a higher silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth varieties for that SCA 04××, SC 25××, SC 06×× on the preceding web page and PS silent chains to ensure silent high velocity operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
