Manufacturers Assocation (CEMA) recom-mends that wing pulleys not be used on belts traveling over 2,25 meters per second (450 ft/min). A better choice than the conventional winged tail pulley is a spiral-wrapped tail pulley (Figure 6.5). These pulleys have an additional steel strip wrapped in a spiral around the pulley circumference. The steel

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. The wrap factor can be as small as 0.08 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420 of wrap angle, or as large as 1.2 for a single drive system ...
