Why choose Bonfiglioli worm gearboxes?

Worm gearboxes represent a fundamental solution for the industrial transmissions sector. Choosing a brand like Bonfiglioli means focusing on a product that has made mechanical history, guaranteeing a perfect balance between high performance, exceptional operational efficiency, and durability over time, even in the most demanding environments.

The efficiency of these worm gearboxes is reflected in smooth and silent motion transmission, ideal for machinery requiring constant precision and reliability. Relying on FP Trasmissioni for the supply of these products ensures not only access to high-quality components but also specialized technical support for every design requirement, ensuring that each technical selection perfectly aligns with your specific industrial application and performance targets.

VF Series and W Series: an innovative and flexible design

The VF and W series are the benchmark for those seeking a worm gearbox that combines tradition and modernity. Their innovative design is not merely an aesthetic matter, but a structural one. Worm gearboxes guarantee absolute flexibility through the choice of numerous product configurations, on both the input and command sides, all offered on a standard basis.

The VF Series stands out for its lightness, while the W Series is designed for heavy loads. Helical-worm and double-worm configurations are also available, with or without a torque limiter device, to create a versatile and complete system. This modularity allows for a precise response to the most complex technical challenges.

Technical Specifications of the VF and W Series

For designers requiring certain data, here are the main performances offered by our range:

• Transmissible torque: from 13 Nm to 7,100 Nm.

• Rated power (n1=1400 min-1): from 0.04 kW to 75 kW.

• Gear ratios: from 7 to 10,000.

Regarding the output configuration, it is possible to choose between a hollow output shaft with keyway, a cylindrical shaft (single or double-sided), and the torque limiter option. On the input side, IEC standard motor adapters or cylindrical shafts are available, making every worm gearbox extremely adaptable.

Motorizations and cutting-edge options

Motor coupling is a crucial aspect. Our solutions include three-phase motorizations with M series compact motors or IEC series BN normalized motors, both available with or without brakes and in single or double polarity versions.

The braking system is another element of safety and precision, with DC or AC power supply and different reactivity levels obtainable through AC/DC rectifiers. Among the main motor options, we find:

• Thermistor or bimetallic thermal probes.

• Forced ventilation with separate power supply.

• Incremental encoder of line driver or push-pull type.

3D model visualization of the gearbox

To provide a clear overview of the product’s conformation, we have included a section dedicated to 3D model visualization. This is a unique model for each type of gearbox, designed exclusively to allow a close observation of the component’s aesthetics and structure directly online.

This visual resource is useful for better understanding how the gearbox is constructed in its essential lines. It is important to emphasize that, as these are simplified models for illustrative purposes, they are not intended for verifying technical dimensions during the CAD design phase, but represent an informative value for quickly identifying the VF or W series.
