Reduction Gearbox Efficiency = Consult unit details, if no reduction gearbox present assume efficiency of 100% Note For actuators connected in-line the worm shaft can transmit up to 3 times the torque for a single actuator atits maximum capacity, except the 1820 Unit which can transmit 1.5 times the torque (refer 1.5.2.2.2.).

1.1.3.2.9.Typical System Configurations

‘H’ Configuration‘U’ Configuration ‘H’ and ‘U’ configured actuator systems are typical and include actuators, motor, bevel gearboxes, reduction gearboxes, drive shafts,couplings and plummer blocks.Actuator arrangements can be built in many formats with the use of bevel gear boxes which allow the direction of drive rotation to beselected on assembly. The gear boxes come in 2, 3 and 4 way drive types (refer 4.0).
