SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and particular plates to accomplish an ideal engagement mechanism, and may maintain a noise level remarkably lower than standard roller chains.
SC kind silent chains is often employed for large velocity and substantial stress transmission just like a toothed metallic belt since the plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are built with inner engaging structure for even further lowered noise degree.
PS silent chain
A PS sort silent chain features a framework in which a set of specially formed connecting pins and locker pins get hold of each and every other although rotating at each and every flexible bearing position. Therefore, it generates less heat particularly in substantial speed operation and is superb in durability. In addition, the specially formed pins significantly lower shock when the chain is engaged with sprockets, giving a larger silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× within the preceding webpage and PS silent chains to make certain silent higher speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
