Purchase now: Bonfiglioli VF 49 F1 10 P80 B5 Gearbox
Purchase now: Atlantechdrives provides you the VF 49 F1 10 P80 B5, a highly versatile, industrial-grade worm gear reducer expertly engineered by the global power transmission specialists at Bonfiglioli. Belonging to the widely utilized and extremely reliable VF Series, this gearbox is the industry standard for space-constrained, 90-degree power transmission applications. This specific unit features a fast 10:1 reduction ratio. This minimal torque multiplication factor provides a very high output rotational speed, making it the ultimate solution for fast-moving conveyor belts, rapid packaging lines, and quick rotary sorting mechanisms. Configured with a specialized «F1» side-mounted output flange, it allows for rigid, direct bolting to your machine’s chassis. It is pre-configured to seamlessly accept a standard IEC P80 electric motor via a large B5 mounting flange. The high-quality die-cast aluminum housing ensures excellent thermal heat dissipation while keeping the overall assembly incredibly lightweight, drastically reducing structural strain on your automated frames.
Technical Specifications of the VF 49 F1 10 P80 B5
The VF 49 size utilizes a precision-machined, profile-ground steel worm shaft driving a centrifugally cast bronze worm wheel. Because of the low 10:1 ratio, the lead angle of the worm is steep, providing exceptionally smooth sliding friction and high mechanical efficiency for a worm drive.

Expert Tips: Total Dynamic Reversibility of Fast Ratios
When selecting a worm gearbox, understanding the mechanical properties and tribology of your chosen ratio is absolutely critical for machine safety. Expert Tip: Many engineers make the dangerous assumption that all worm gearboxes are inherently self-locking and will act as mechanical brakes. Because the VF 49 features a fast 10:1 reduction ratio, the lead angle of the internal steel worm thread is incredibly steep. This geometry means the gearbox is completely dynamically reversible. Any heavy load or kinetic energy applied to the output shaft will easily «back-drive» the gearbox and spin the electric motor backward when the power is turned off. It offers almost zero mechanical braking resistance. If your application involves an inclined conveyor, a suspended load, or requires precise emergency stops, you must never rely on a 10:1 worm gear to hold the load. You must install an external electromechanical brake on your AC motor.
Installation Advice: F1 Flange and Fretting Prevention
This specific model utilizes an F1 output flange, allowing the gearbox to be securely bolted directly to the sidewall of your machinery, eliminating the need for bulky reaction torque arms. The VF 49 is a factory-sealed unit, pre-filled with high-performance synthetic ISO VG gear oil. It is «lubricated for life,» meaning it lacks breather or drain plugs, allowing for installation in almost any physical orientation. When mounting your IEC P80 motor into the B5 input flange, you must apply a premium anti-seize paste (such as Molybdenum Disulfide) to the solid motor shaft before inserting it into the gearbox input quill. Without this paste, microscopic vibrations will cause fretting corrosion, essentially cold-welding the motor to the gearbox.
Frequently Asked Questions (FAQs)
Q: Can I change the orientation of the F1 output flange?
A: Yes. The F1 flange is modular. By removing the retaining bolts, the flange can generally be swapped to the opposite side of the gearbox housing to accommodate different machine mounting configurations.
Q: Will the aluminum casing get hot during continuous operation?
A: Yes. Because a worm gear relies on sliding friction, a portion of the electrical energy is converted into radiant heat. The aluminum casing is designed to run warm or hot to the touch during continuous duty cycles.
