Apr 20, 2020This formula differs from the friction factor based formulations in the inter national standards like DIN-22101 and ISO-5048 in one important aspect: the CEMA classic method provides designers with charts of friction factor vs belt tension, belt load, temperature, and idler pitch. The other standards simply state that belt friction should be set based on the experience

The historical method that CEMA provides to calculate T2 slip is as follows: T2 slip = Te x Cw, where Cw is the CEMA wrap factor for a rubber surfaced belt.
