Combined gearboxes - specifications Output speed Bonfiglioli’s 3/H gearboxes combine the high technology, performance and efficiency of planetary gearboxes with the robustness, quality and reliability of bevel helical gearboxes. These planetary/bevel helical combination gearboxes deliver the high transmissible torque of our 300 Series along with the excellent power transmission characteristics of our HDO Series and are ideal for applications that demand high power density along with medium-low output speeds. The 3/H range consists of 10 standard catalogue sizes that can transmit up to 1200 kNm...

Fields of application 3/H combined gearboxes are specially designed for use in high power applications in industries like mining, metal, paper and sugar. Mining industry Metal industry Sugar industry Paper industry

Variants Output versions • solid cylindrical shaft • solid shaft with keyway p a • solid shaft with supporting feet • solid shaft with keyway and supporting feet • hollow shaft with shrink disc • hollow shaft with keyway Input versions • Single sided cylindrical shaft • Flange with motor coupling bell and intermediary elastic joint between the cylindrical shafts of the motor and gearbox. Mounting position • Horizontal input shaft • Vertical input shaft Shaft arrangement Depending on the needs of the application, 3/HDO combination □□ □□ gearboxes can be supplied with output shafts on the...

Auxiliary thermal devices The heat dissipation of 3/HDO combination gearboxes can be improved by the addition of devices like: • cooling fans keyed on to the shaft • integrated cooling circuit with heat exchange coil • autonomous cooling units • electrical heating elements if very low ambient temperatures make it necessary to pre-heat the lubricant in the casing before start-up and/or during operation. Forced lubrication Standard lubrication is based on a splash system, but forced lubrication can be provided for use in special applications based on: • forced lubrication circuits with mechanically...

Special solutions Special, complete and custom power transmission solutions are available for specific applications involving: • Torque arms The design of this accessory generally depends on the customer's machine. In addition to a standard offering, Bonfiglioli can also supply made to measure torque arms for specific applications. • Base plates Depending on the weight of the motor and/or the number of accessories needed for the combination gearbox, it may prove necessary to install a base plate. Base plate configuration depends on the overall weight of the assembled gearbox, motor and accessories. •...
