SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to accomplish a perfect engagement mechanism, and may continue to keep a noise degree remarkably reduced than typical roller chains.
SC type silent chains may be made use of for large velocity and substantial stress transmission similar to a toothed metallic belt since the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are designed with inner engaging construction for additional lowered noise degree.
PS silent chain
A PS form silent chain features a structure by which a set of specially formed connecting pins and locker pins get in touch with just about every other even though rotating at every single flexible bearing place. Consequently, it generates significantly less heat primarily in large velocity operation and is superb in sturdiness. Furthermore, the specially formed pins significantly lower shock when the chain is engaged with sprockets, delivering a higher silencing impact than SC silent chains.
Sprockets for silent chains adopt special modules in involute tooth kinds for that SCA 04××, SC 25××, SC 06×× to the previous webpage and PS silent chains to ensure silent substantial speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
