SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to attain a great engagement mechanism, and will keep a noise level remarkably reduce than typical roller chains.
SC form silent chains may be utilized for substantial speed and huge stress transmission much like a toothed metallic belt because the plates right engage together with the sprockets for driving.
SCR-04 silent chains are built with inner engaging framework for even more 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 just about every other when rotating at every versatile bearing position. Hence, it generates significantly less heat in particular in high velocity operation and it is excellent in durability. On top of that, the specially formed pins enormously lower shock once the chain is engaged with sprockets, supplying a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× about the former page and PS silent chains to guarantee silent substantial velocity operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
