Purchase now: Bonfiglioli VF 49 P1 100 P71 B14 B3 Gearbox
Purchase now: Atlantechdrives provides you the VF 49 P1 100 P71 B14 B3, a highly versatile, ultra-compact fractional worm gear reducer expertly engineered by the global power transmission specialists at Bonfiglioli. Belonging to the lightweight and widely utilized VF Series, this gearbox is the absolute industry standard for space-constrained, 90-degree power transmission applications. This specific unit features an extreme 100:1 reduction ratio. This massive torque multiplication factor makes it the ultimate solution for ultra-slow moving conveyor belts, heavy-duty rotary indexing tables, precision positioning machinery, and automated dosing systems where incredibly slow, deliberate mechanical movement is strictly required. Configured with a standard «P1» foot-mounted housing, it provides integral mounting feet and a hollow output shaft for seamless, direct machine integration. It is specifically pre-configured to accept a fractional IEC P71 electric motor via a compact B14 face-mount flange. The high-quality die-cast aluminum housing ensures excellent thermal heat dissipation while keeping the overall assembly extremely lightweight, minimizing structural strain on your automated frames and mobile factory machinery.
Technical Specifications of the VF 49 P1 100 P71 B14 B3
The VF 49 size utilizes a precision-machined, profile-ground steel worm shaft driving a centrifugally cast bronze worm wheel. Under the intense sliding friction of a 100:1 ratio, this premium metallurgical pairing guarantees exceptional longevity, providing reliable 24/7 continuous operation even under substantial torque loads.

Expert Tips: Absolute Static Irreversibility and Self-Locking
When selecting a worm gear, understanding the mechanical properties and tribology of your chosen ratio is critical for machine safety and efficiency. Expert Tip: The massive 100:1 reduction ratio places the VF 49 firmly into the category of absolute static irreversibility (self-locking). The lead angle of the internal steel worm thread is incredibly shallow. This precise mechanical geometry ensures that when the electric motor is turned off, the internal friction angle is so steep that absolutely no amount of kinetic load on the output shaft can back-drive the gearbox. It acts as a highly effective, natural mechanical brake, securely holding suspended loads or heavy inclined conveyors perfectly stationary. However, automation engineers must remember that this immense holding power comes at the cost of mechanical efficiency; a significant percentage of the electric motor’s energy is lost to sliding friction rather than converted to rotational torque.
Installation Advice: B14 Flange and Thermal Lubrication Limits
This specific model utilizes a B14 motor input flange, which is a face-mount design that drastically reduces the overall footprint of the assembly compared to a bulky B5 flange. The VF 49 is a factory-sealed unit, pre-filled with high-performance synthetic ISO VG gear oil. It is completely «lubricated for life,» meaning it lacks breather, drain, or fill plugs. When mounting your IEC P71 motor (which features a 14mm solid shaft and a 105mm flange diameter), you must apply a premium anti-seize paste (such as Molybdenum Disulfide) to the motor shaft before inserting it into the gearbox input quill. Because the 100:1 ratio generates massive amounts of heat, preventing fretting corrosion on the input shaft is absolutely vital, otherwise the motor will cold-weld to the gearbox over time.
Frequently Asked Questions (FAQs)
Q: What does the P1 output designation mean for the VF 49?
A: The P1 designation refers to Bonfiglioli’s standardized housing geometry. It indicates that the aluminum housing features standard integral mounting feet cast directly into its base and a hollow output shaft bore with a standard keyway for simple integration.
Q: Will the aluminum casing get hot during continuous 24/7 operation?
A: Yes, absolutely. A 100:1 worm gear generates a tremendous amount of sliding friction, converting a large portion of the electrical energy directly into radiant heat. The aluminum casing is specifically designed with cooling fins to act as a heat sink and will run very hot to the touch during continuous duty cycles.
