Clutches & Gearboxes BD Engine Mounted Clutches 5 *Maximum torque figures do not include service factor. ** R = PTO to accept high radial load. The formula shown below will enable the radial loading to be calculated. The figure should be compared with the maximum permissible radial load shown against distance (x) in table (A). F = side load (daN) kW = Input power (kW) n = output shaft speed (rpm) D = pitch diameter of pulley (m) f = load factor 1.0 for chain or gear drive 2.5 for V belts 3.5forlatbelts f 1 = 2 only for reciprocating compressor or severe shock drives. The resulting F value is to be lower or equal to that quoted on the table, according to the distance X. F = 1910 x kW x f x f 1 n x D
