SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to accomplish a great engagement mechanism, and can retain a noise level remarkably lower than conventional roller chains.
SC type silent chains might be used for large pace and big tension transmission much like a toothed metallic belt since the plates directly engage using the sprockets for driving.
SCR-04 silent chains are made with inner engaging structure for additional diminished noise degree.
PS silent chain
A PS kind silent chain includes a framework in which a set of specially formed connecting pins and locker pins get hold of each other though rotating at just about every flexible bearing position. Therefore, it generates less heat specifically in higher velocity operation and is great in sturdiness. Additionally, the specially formed pins enormously reduce shock when the chain is engaged with sprockets, delivering a increased silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth forms to the SCA 04××, SC 25××, SC 06×× over the prior web page and PS silent chains to ensure silent substantial velocity operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
