Hydraulic gearmotors

Gearboxes are mechanical transmission devices that multiply the output torque of the input axle. They can increase the torque of a hydraulic motor as well as the rotation speed of the driven gear.

Are you looking for a company that sells Bonfiglioli Trasmital gearboxes? Do you need to purchase gearboxes for lifting and traction systems? Would you like delivery stock availability of gearboxes for earth moving machines, agricultural machines and mini excavators?

Please contact us. Our engineers are available to size and configure the servo motor and gearbox that best fits your requirements.

There are 4 types of gearboxes:

  • Planetary gearboxes
  • Worm gearboxes
  • Gearboxes with gear train
  • Bevel gearboxes

Based on the application, we will assist you in finding the type of gearbox that best suits your needs.


Factors to consider before purchasing a gearbox

Before buying a gearbox, you need to take into account a number of factors.

Firstly, you need to consider torque. Gearboxes make it possible to increase the torque of a motor and therefore change the rotation speed of the driven gear. Some manufacturers indicate for each product the minimum and maximum torque, expressed as Newton-metre (Nm), that the gearbox can withstand. Torque density varies from gearbox to gearbox.

Another function served by these devices is to reduce motor speed. If you need a gearbox for this purpose, we recommend you calculate the ideal reduction ratio for your application before making your purchase. Once you have the reduction ratio, you can calculate the output rotation speed from the rotation speed of the motor.  This value is included in the technical specifications provided by manufacturers and is expressed as rotation per minute (rpm).

Finally, you need to take into account the type of gearbox installation. The input and output shafts of the gearbox can be coaxial, parallel or orthogonal. The choice of axle orientation will depend on the application of the gearbox.
