Selection

Е Calculate the torque to transmit (Nm)P : power (kW)C = 9550 x P N : rotation speed (rpm) N Correct the torque value mutiplying it by the service factor in the table below Internal combustion en g ines - 1 to 3 c y linders - unevenness factor : 1/80 to 1/100 Internal combustion engines - 4 to 6 cylinders - unevenness factor : 1/100 to 1/200 Electric motor - Steam turbine - Water turbine Load t yp eDriven machines LightAgitators - Conveyors - Centrifugal compressors - Dynamometers - Air filter - Generators - 1,01,52,0 dutyShafts lines - Centrifugal pumps - Centrifugal fans MediumAgitators - Lifting material - Overshot elevator - Textile machinery - Machine tools - 1,52,02,5 dutyWood working machinery - Mixers - Gyratory pumps - Printing presses - Hoist - Mining fans HighLifting material - Hammer mills - Crushers - Rotative compressors - Dredgers - Calenders - 2,02,53,0 dutyGyratory furnaces - Brick machinery - Cutting presses High inertia ShocksGyratory crushers - Alternative conveyors - Vibrating screens - Alternative compressors 2,53,03,5 Torque inversionRubber calenders - Mills - Alternative pumps Rotation inversion Օ Check that the rectified torque is below the nominal torque of the coupling >

Installation

The couplings exist in a pre-bored version (type C) or with a VECOBLOC >
ծ removable bush (type CV) For the CV type, the installation position of the FF, HH or FH bush (see over) must be specified with order Օ A correct alignment of the shafts gives the length of live of the coupling >
