Purchase now: Bonfiglioli VF 30 P1 40 P63 B14 B3 Gearbox
Purchase now: Atlantechdrives provides you the VF 30 P1 40 P63 B14 B3, an ultra-compact, highly reliable worm gear reducer engineered by the global transmission specialists at Bonfiglioli. As the smallest and most space-efficient member of the widely utilized VF Series, this gearbox is the absolute industry standard for fractional horsepower, 90-degree power transmission. This specific unit is configured with a versatile 40:1 reduction ratio, making it an excellent solution for slow-moving conveyor belts, small indexing tables, and precision automated dispensing machinery. Featuring a standard P1 output configuration, it is ready to accept an IEC P63 electric motor via a compact B14 face-mount flange. The die-cast aluminum housing provides exceptional heat dissipation while ensuring the unit remains extremely lightweight, perfect for integration into mobile machinery, robotic end-effectors, or suspended frames without causing excessive structural strain.
Technical Specifications of the VF 30 P1 40 P63 B14 B3
The VF 30 size utilizes a precision-machined steel worm shaft driving a centrifugally cast bronze worm wheel. This metallurgical pairing guarantees smooth sliding friction, low operational noise, and exceptional longevity under fractional loads.

Expert Tips: Static Irreversibility
Understanding the mechanical properties of a 40:1 worm gear ratio is critical for machine safety. Expert Tip: The 40:1 reduction ratio places the VF 30 firmly in the category of static irreversibility (self-locking). This means that when the electric motor is turned off, the friction angle of the internal worm thread is steep enough that a load on the output shaft will generally not be able to «back-drive» the motor. It acts as a natural mechanical brake holding the load in place. However, if the machine frame is subjected to sudden shocks or intense vibrations, the static friction can break, causing the load to slip. If your application involves a critical safety lift, you must still install an external electromechanical brake on your AC motor.
Installation Advice: B14 Flange Integration
The VF 30 is a factory-sealed unit, pre-filled with high-performance synthetic gear oil. It is completely «lubricated for life,» meaning it lacks breather, drain, or fill plugs. This eliminates the need for periodic oil changes and prevents leaks. This specific model features a B14 motor input flange. Unlike the massive B5 flange, the B14 is a «face-mount» design. When mounting your IEC P63 motor, you must apply a premium anti-seize paste (such as Molybdenum Disulfide) to the motor shaft before inserting it into the gearbox input quill. Without this paste, fretting corrosion will occur over time, essentially cold-welding the motor to the gearbox and making future maintenance impossible.
Frequently Asked Questions (FAQs)
Q: What does the P1 output designation mean?
A: The P1 designation refers to Bonfiglioli’s standardized housing geometry for the VF series. It indicates that the gearbox housing features standard integral mounting feet and a hollow output shaft bore with a standard keyway.
Q: Will the aluminum casing get hot during normal operation?
A: Yes. Worm gears rely on sliding friction, which converts lost energy into radiant heat. The aluminum casing is designed to run warm or even hot to the touch during continuous duty cycles, which is a perfectly normal characteristic of worm drives.
