Technical Description: Bonfiglioli RAN 15 DA 1
The Bonfiglioli RAN 15 DA 1 is a precision right-angle bevel gear unit designed for industrial transmissions requiring high accuracy and a compact layout. The RAN series is engineered to provide efficient direction change in power transmission lines, making it a vital component in synchronized conveyor systems, shaft-driven machinery, and positioning equipment where multiple outputs are required from a single input.
Configuration and Mechanical Integrity
The RAN 15 size features a robust, high-quality aluminum housing that provides structural rigidity and lightweight handling. This specific model, the DA 1, indicates a double output shaft configuration with a 1:1 gear ratio. This allows the unit to transmit torque at the same speed as the input while splitting the drive into two 90-degree directions, ensuring perfect synchronization between two separate machine sections.
Detailed Characteristics
- Series: RAN (Bevel Gear).
- Size: 15.
- Gear Ratio (i): 1:1.
- Shaft Arrangement: DA (Double Output Shaft).
- Input Power: Optimized for high-speed mechanical drives.
- Gears: Case-hardened spiral bevel gears for quiet operation.
- Lubrication: Long-life lubricant pre-filled.
Operational Benefits
Bonfiglioli spiral bevel gears are ground to high tolerances to ensure minimal backlash and high mechanical efficiency (often exceeding 95%). The RAN 15’s compact dimensions allow for easy integration into tight machine designs. Its multi-surface mounting capabilities make it one of the most versatile right-angle units in the power transmission market, capable of horizontal, vertical, or side-wall installation.
