Purchase now: Bonfiglioli VF 49 P1 45 P80 B14 B3 Gearbox
Purchase now: Atlantechdrives provides you the VF 49 P1 45 P80 B14 B3, a highly durable, compact worm gear reducer engineered by the global specialists at Bonfiglioli. As a core component of the widely utilized VF Series, this gearbox is the absolute industry standard for reliable, 90-degree power transmission in space-constrained industrial environments. This specific unit is configured with a mid-to-high 45:1 reduction ratio, making it an excellent torque multiplier for conveyor belt drives, rotary packaging tables, and automated gate operators. Featuring a P1 output configuration, it is ready to accept a standard IEC P80 electric motor via a compact B14 face-mount flange. The aluminum die-cast housing provides excellent heat dissipation while ensuring the unit remains lightweight enough for integration into mobile machinery or suspended conveyor frames.
Technical Specifications of the VF 49 P1 45 P80 B14 B3
The VF 49 size is engineered with a profile-ground steel worm shaft driving a high-grade bronze worm wheel. This time-tested metallurgical pairing guarantees smooth sliding friction, low operational noise, and exceptional longevity under varying loads.

Expert Tips: The «Gray Zone» of Self-Locking
When selecting a worm gearbox, engineers must carefully evaluate the self-locking capabilities of the chosen ratio. Expert Tip: The 45:1 reduction ratio places the VF 49 squarely in the mechanical «gray zone.» Gearboxes with a ratio below 30:1 are highly reversible (they will spin backward if pushed). Gearboxes with a ratio of 60:1 or 80:1 are statically irreversible (they act as a mechanical brake and will not spin backward). At 45:1, the gearbox will generally hold a load stationary, but if the machine frame experiences a sudden vibration, a shock, or a temperature change that alters the oil viscosity, the static friction will break, and the load will suddenly back-drive the motor. Therefore, if your application involves an inclined conveyor or a lifting hoist where a falling load presents a safety hazard, you must not rely on the 45:1 worm gear to act as a brake. Always install an external failsafe electromechanical brake on your AC motor.
Maintenance and B14 Flange Integration
The VF 49 is a factory-sealed unit, pre-filled with high-performance synthetic gear oil. It is «lubricated for life,» meaning it has no breather, drain, or fill plugs, completely eliminating the need for periodic oil changes and preventing leaks regardless of mounting orientation. This specific model features a B14 motor input flange. Unlike the massive B5 flange, the B14 is a «face-mount» design. The mounting bolts pass directly through the gearbox casting and thread into the face of the electric motor. This significantly reduces the outer diameter of the assembly, making it the perfect choice for squeezing into tight machine guards where radial space is at a premium. Always ensure you apply anti-seize paste to the motor shaft before inserting it into the gearbox quill to prevent fretting corrosion.
Frequently Asked Questions (FAQs)
Q: What does the P1 output designation mean?
A: The P1 designation refers to Bonfiglioli’s standardized housing geometry for this size. It means the gearbox housing features standard mounting feet and a standard hollow output shaft bore, as opposed to specialized flange-mount (F) or extended shaft configurations.
Q: Will the gearbox get hot during normal operation?
A: Yes. Because a 45:1 worm gear relies on sliding friction, it is less efficient than a helical gear (typically operating around 60-70% efficiency). The lost energy is converted into radiant heat. The aluminum casing is designed to run hot to the touch during continuous duty cycles.
