SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to realize an ideal engagement mechanism, and can continue to keep a noise level remarkably reduced than typical roller chains.
SC kind silent chains is usually utilized for large pace and large tension transmission similar to a toothed metallic belt since the plates directly engage using the sprockets for driving.
SCR-04 silent chains are developed with inner engaging framework for even further diminished noise degree.
PS silent chain
A PS type silent chain features a construction through which a set of specially formed connecting pins and locker pins get in touch with every single other even though rotating at just about every versatile bearing position. So, it generates much less heat specially in higher speed operation and it is fantastic in durability. On top of that, the specially formed pins enormously decrease shock when the chain is engaged with sprockets, delivering a higher silencing impact than SC silent chains.
Sprockets for silent chains adopt specific modules in involute tooth forms for the SCA 04××, SC 25××, SC 06×× within the previous web page and PS silent chains to guarantee silent higher velocity operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
