SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize an ideal engagement mechanism, and can hold a noise degree remarkably reduce than traditional roller chains.
SC form silent chains is usually applied for higher pace and massive tension transmission much like a toothed metallic belt since the plates directly engage using the sprockets for driving.
SCR-04 silent chains are built with inner engaging structure for further decreased noise level.
PS silent chain
A PS variety silent chain features a framework in which a set of specially formed connecting pins and locker pins contact every single other although rotating at each and every versatile bearing position. Hence, it generates significantly less heat specially in higher pace operation and is excellent in sturdiness. Additionally, the specially formed pins enormously lessen shock once the chain is engaged with sprockets, offering a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth types to the SCA 04××, SC 25××, SC 06×× within the past web page and PS silent chains to guarantee silent large velocity operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
