Planetary Gearboxes

The use of planetary gear units in the field of power transmission is the modern answer to the demand for compactness, constructive simplicity and product reliability.
PG planetary gear units are divided into 21 basic groups depending on the different torques that are to be transmitted to the output shaft, which can vary from 0.5 to 65 kNm.
In fact, the SOM product modular construction permits the coupling of bevel gears, worm gears, hydraulic brakes and a variety of input shafts to the planetary units, as well as providing for a wide choise of coupling flanges for hydraulic or electric motors.
Another advantage offer by the modular construction technique of the planetary gear units is the possibility to mount a series of stages of different sizes in order to obtain a vast range of reduction ratios.
The SOM product range provides reduction ratios from 3,55:1 to 7:1 on single stage unit up to 10,000:1 and more on a 5 stage unit.
The wide selection of output shafts and flanges simplifies the reduction unit mounting operation on industrial machinery or plants.
