High Efficiency Right-Angle Drive: Bonfiglioli MVF44/F1 20
The Bonfiglioli MVF44/F1 20 P71 B14 B3 is a high-performance worm gear unit engineered for industrial applications requiring reliable torque transmission in a compact, right-angle layout. Part of the legendary VF/MVF series, this size 44 unit is designed to provide high mechanical efficiency and silent operation. It is a critical component for conveyor systems, packaging machinery, and automated gates where durability and space-saving design are paramount.
Technical Configuration and Performance
This unit features a reduction ratio of 20:1, providing a significant mechanical advantage. It is configured with an IEC motor flange (P71) and a B14 face, specifically designed for a B3 mounting position (horizontal foot mounting). The «F1» designation indicates a specific output flange configuration, allowing for direct integration into machine frameworks without the need for additional couplings.
Key Features
- Frame Size: 44 (Aluminum die-cast housing).
- Gear Ratio (i): 20.
- Input Flange: P71 B14 (IEC Standard).
- Mounting Position: B3 (Horizontal).
- Lubrication: Typically pre-filled with synthetic oil for maintenance-free operation.
- Gearing: Hardened steel worm and high-quality bronze wheel.
Operational Reliability
The MVF series is recognized for its «Universal Mounting» versatility. The high-pressure die-cast aluminum housing ensures excellent thermal dissipation, preventing oil degradation during continuous S1 duty cycles. The precision-ground worm and wheel geometry minimize friction, leading to cooler operation and extended service intervals.
