Link belt

[Lee Schierer]

Can someone tell me what function those transverse, or lateral, outer ribs might serve for SawStop? To my eyes it would only increases air turbulence with slightly increased mass and power loss.

Some of the molded poly ribbed v belts have the transverse ribs. I think it makes them slightly more flexible. We used to use them in our assembly machines where I used to work. Sears also used them in some later model Craftsman saws for drive belts. Gates also has one called the gator back that has diagonal notches in the v-ribs.

Link belts come in many sizes. I saw their booth at an industrial trade show. I'm pretty sure I saw them up to at least 1".

The cogs on the poly v belts are to keep them flat across the width of pulley surface. IThe cogging gives you the flexibility to get around relatively small pulley diameters.
