SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to accomplish a great engagement mechanism, and will hold a noise level remarkably reduced than standard roller chains.
SC kind silent chains is usually utilised for high velocity and substantial stress transmission just like a toothed metallic belt because the plates right engage with all the sprockets for driving.
SCR-04 silent chains are made with inner engaging structure for additional lowered noise level.
PS silent chain
A PS sort silent chain has a construction through which a set of specially formed connecting pins and locker pins contact just about every other when rotating at every single flexible bearing place. Hence, it generates less heat particularly in higher pace operation and it is fantastic in sturdiness. Moreover, the specially formed pins tremendously lessen shock once the chain is engaged with sprockets, delivering a higher silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth forms to the SCA 04××, SC 25××, SC 06×× to the preceding page and PS silent chains to ensure silent high speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
