MINIMUM RECOMMENDED DIAMETERS FOR BELT'S PULLEYS
Diameters changes in
function to the number, the type of the belts, and work conditions.
Diameters
values to
the EP-125 and carcass with 2,3 and 4 stuffs are as follows:
| UNTIL 30% MAT | BETWEEN 30% - 60% | MORE THAN 60% MAT |
| MP | TP | DP | MP | TP | DP | MP | TP | DP | |
| 250/2 | 160 | 160 | 125 | 200 | 200 | 160 | 250 | 250 | 200 |
| 400/3 | 315 | 250 | 200 | 315 | 250 | 250 | 400 | 315 | 250 |
| 500/4 | 400 | 315 | 250 | 400 | 400 | 315 | 500 | 500 | 400 |
MAT = Maximum admissible tension.
MP = Driving pulley and pulleys under maximum tension.
TP = Tail pulley.
DP = Deflection pulley.
