Technical Description: Bonfiglioli A 10 2 NH 15 P71 B5
The Bonfiglioli A 10 2 NH 15 P71 B5 is a right-angle helical-bevel gearbox engineered for applications where space and energy efficiency are critical. Unlike traditional worm gearboxes, the A Series offers significantly higher efficiency, translating to lower energy consumption and reduced heat generation. The size 10 frame is a robust solution for medium-torque requirements in automated logistics and food processing lines.
Mechanical Configuration
This model features a 2-stage reduction with a ratio of 15:1. The NH designation indicates a hollow shaft with a keyway, which allows for direct mounting onto the driven machine’s shaft, eliminating the need for couplings. It is prepared for a P71 B5 IEC motor, making it a «plug-and-play» solution for standard industrial motors.
Detailed Characteristics
- Part Number: A 10 2 NH 15 P71 B5.
- Type: Helical-Bevel (Right Angle).
- Stages: 2 stages of reduction.
- Output Shaft: Hollow shaft with keyway (NH).
- Gear Ratio: 15.
- Motor Connection: P71 B5 flange.
- Housing Material: High-pressure die-cast aluminum (Size 10).
Operational Benefits
The A 10 2 NH is designed for «Universal Mounting,» meaning it can be installed in any orientation without major modifications (check oil levels for vertical positions). The helical-bevel gears provide a smooth, low-noise power transmission that is essential for clean-room or quiet factory environments. The hollow shaft design reduces the overall length of the drive train, allowing for more compact machine footprints.
