Purchase now: Bonfiglioli VF 30 P1 15 P63 B5 B3 Gearbox
Purchase now: Atlantechdrives provides you the VF 30 P1 15 P63 B5 B3, a highly responsive, ultra-compact fractional worm gear reducer expertly engineered by the global power transmission specialists at Bonfiglioli. As a highly sought-after size within the widely implemented VF Series, this fractional gearbox represents the absolute industry standard for space-constrained, 90-degree power transmission applications. This specific unit features a fast 15:1 reduction ratio. This minimal torque multiplication factor provides a very high output rotational speed, making it the ultimate solution for fast-moving small conveyor belts, rapid automated packaging mechanisms, precision dosing pumps, and light-duty material handling where swift movements are required. Configured with a standard «P1» output housing, it provides integral mounting feet and a hollow output shaft for seamless, direct machine integration. It is perfectly built to accept a standard IEC P63 electric motor via a large B5 mounting flange. The die-cast aluminum casing guarantees exceptional thermal dissipation while keeping the overall assembly extremely lightweight, minimizing structural strain on your robotic end-effectors or mobile automated frameworks.
Technical Specifications of the VF 30 P1 15 P63 B5 B3
Despite its exceptionally small footprint, the VF 30 utilizes a precision-machined steel worm shaft driving a centrifugally cast bronze worm wheel. Because of the low 15:1 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 a 15:1 Ratio
Understanding the tribology and mechanical properties of your selected worm gear ratio is absolutely critical for machine safety. Expert Tip: Many junior engineers make the dangerous assumption that all worm gearboxes act as natural mechanical brakes. Because the VF 30 features a fast 15:1 reduction ratio, the lead angle of the internal steel worm thread is incredibly steep. This geometry makes the gearbox highly mechanically efficient, but it also means the gearbox is completely dynamically reversible. This signifies that any load or kinetic energy applied to the output shaft can effortlessly «back-drive» the gearbox and spin the electric motor backward when the power is turned off. It offers zero mechanical braking force. If your micro-application involves lifting, holding a suspended weight against gravity, or requires sudden emergency stops, you must never rely on a 15:1 worm gear to hold the load. You must install an external failsafe electromechanical brake on the AC motor.
Installation Advice: B5 Flange and Factory Lubrication
The VF 30 is a factory-sealed, completely maintenance-free unit. It is pre-filled with the exact required volume of high-performance synthetic ISO VG gear oil and is «lubricated for life.» It deliberately lacks breather, fill, or drain plugs, completely eliminating the need for periodic oil changes and allowing the unit to operate reliably in almost any orientation. When mounting your IEC P63 motor into the large B5 input flange, you must apply a premium anti-seize paste (such as Molybdenum Disulfide) to the solid motor shaft. Without this critical paste, microscopic vibrations will cause severe fretting corrosion, essentially cold-welding the motor to the gearbox’s input quill and making future motor replacement impossible without causing severe damage.
Frequently Asked Questions (FAQs)
Q: What does the P1 output designation signify for the VF 30?
A: The P1 designation refers to Bonfiglioli’s standardized housing geometry. It means the aluminum casing is cast with integral mounting feet at its base and features a standard hollow output shaft bore with a keyway for simple, direct-drive machine integration.
Q: Will the aluminum casing get hot during continuous 24/7 operation?
A: Yes. Because all worm gears rely on sliding friction, a portion of the mechanical energy is always converted into radiant heat. The aluminum casing is specifically designed with cooling fins to dissipate this energy and will run warm or hot to the touch during continuous duty cycles.
