Introduction to the HDP Series: right-angle excellence

The Bonfiglioli HDP Series represents excellence in the field of right-angle gearboxes for Heavy Duty industrial applications. These gearboxes have been developed to offer maximum torque and robustness in configurations requiring a 90-degree motion deviation.

Choosing an HDP Series gearbox means opting for a successful solution. Thanks to their high load capacity, they are able to handle the most severe stresses typical of large production and handling plants.

The right-angle design allows for the optimization of space on the driven machine, offering a more compact and rational component layout. It is the number 1 choice for those who do not want to compromise between power and footprint.

Valuable technical features of the HDP range

The engineering value of the HDP Series is manifested in its superior construction quality. The spheroidal graphite cast iron monobloc housing guarantees exceptional structural rigidity, fundamental for maintaining perfect gear alignment under load.

The series covers a wide range of transmissible torques and reduction ratios, allowing for extraordinary versatility of use in every industrial sector.

Here are the main technical features:

• Precision Bevel Gear Set: Ground Gleason spiral bevel gears for quiet operation and extremely high efficiency.

• Monolithic Housing: Structure designed to absorb vibrations and withstand the most violent mechanical shocks.

• Output Versatility: Hollow shafts with shrink disc, solid or splined shafts for a secure connection to the driven machine.

• Thermal Management: Possibility of integrating forced cooling systems to operate at optimal temperatures even in hot environments.

Effectiveness in 90-degree applications

The use of the HDP Series is particularly effective when the machinery layout requires a right-angle power transmission. In sectors such as mining or steelworking, this configuration is often mandatory for space or mechanical architecture reasons.

Every internal component is dimensioned to guarantee superior fatigue resistance. The precision of the right-angle gears reduces internal friction, transforming almost all the motor energy into effective driving force.

Focusing on the HDP Series is a successful choice that translates into visible energy savings and an operational lifespan that exceeds category standards. It is an investment that guarantees stability and performance over time.

Modular design for complex challenges

The design of the HDP Series allows for a tailored configuration for every need. FP Trasmissioni supports customers in defining every detail, from lubrication devices to external protection systems.

It is possible to integrate various accessories such as backstop devices for inclined belts, hydraulic or pneumatic brakes, and sensors for predictive maintenance.

Competitive advantages of the HDP Series include:

1. Reinforced Seals: Protection systems against external contaminants such as dust, sand, or chemical agents.

2. Input Modularity: Wide range of flanges for coupling with electric or hydraulic motors.

3. Ease of Maintenance: Design studied to allow for rapid inspections and convenient service interventions.

Ideal applications for the HDP Series

The HDP Series finds its natural application in all contexts where 90-degree force and orientation are necessary. It is considered the number 1 solution for various industrial machineries.

Main applications include:

• Large Bucket Elevators: Where motion safety and starting torque are critical.

• Vertical Agitators and Mixers: Ideal for the chemical and cement industries.

• Heavy-duty Conveyor Belts: For handling raw materials in confined spaces.

• Crushing Plants: Where resistance to radial and axial loads is put to the test.

The adoption of this valuable technology allows for raising the quality level of the entire plant, reducing the risks of unforeseen breakdowns and optimizing production cycles.
