SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to achieve a great engagement mechanism, and can continue to keep a noise degree remarkably lower than standard roller chains.
SC form silent chains can be made use of for high pace and huge stress transmission just like a toothed metallic belt because the plates directly engage with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging structure for even more diminished noise degree.
PS silent chain
A PS style silent chain includes a construction during which a set of specially formed connecting pins and locker pins speak to every other even though rotating at each and every versatile bearing place. So, it generates significantly less heat particularly in large pace operation and is great in sturdiness. Furthermore, the specially formed pins considerably lower shock when the chain is engaged with sprockets, providing a larger silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt particular modules in involute tooth types for that SCA 04××, SC 25××, SC 06×× on the earlier webpage and PS silent chains to make sure silent substantial pace operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
