SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to achieve an excellent engagement mechanism, and might hold a noise degree remarkably reduced than traditional roller chains.
SC style silent chains is often employed for large speed and big stress transmission similar to a toothed metallic belt since the plates immediately engage with the sprockets for driving.
SCR-04 silent chains are made with inner engaging structure for more diminished noise level.
PS silent chain
A PS form silent chain features a framework during which a set of specially formed connecting pins and locker pins contact every single other though rotating at each versatile bearing position. As a result, it generates significantly less heat primarily in substantial speed operation and it is exceptional in durability. Furthermore, the specially formed pins considerably cut down shock when the chain is engaged with sprockets, supplying a higher silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× to the earlier web page and PS silent chains to be sure silent high pace operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
