Worm & Wheel Gears

Multibloc 2000 geared motors, with worm and wheel gears, are used to adapt the speed of the electric motor to that of the driven machine.

Their size is, therefore, determined by the motor power (P) expressed in kilowatts (kW) and the output rotation speed of the gear box (nS) in revolutions per minute (min-1). The main characteristic of the speed reducers is the rated output torque (MnS) expressed in Newton-metres (Nm):
