SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to attain an excellent engagement mechanism, and might continue to keep a noise level remarkably lower than typical roller chains.
SC sort silent chains is usually utilised for higher speed and significant tension transmission just like a toothed metallic belt because the plates directly engage using the sprockets for driving.
SCR-04 silent chains are designed with inner engaging structure for even further lowered noise level.
PS silent chain
A PS variety silent chain includes a structure during which a set of specially formed connecting pins and locker pins contact every single other though rotating at every flexible bearing position. So, it generates less heat particularly in large speed operation and it is great in sturdiness. On top of that, the specially formed pins enormously decrease shock once the chain is engaged with sprockets, delivering a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth types for that SCA 04××, SC 25××, SC 06×× on the preceding webpage and PS silent chains to be sure silent large speed operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
